Successful exploitation of this vulnerability could allow a low privileged remote attacker to manipulate register values, which would result in too much or too little odorant being injected into a gas line.
The following versions of GPL Odorizers GPL750 are affected:
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 8.6 | GPL Odorizers | GPL Odorizers GPL750 | Missing Authentication for Critical Function |
A low-privileged remote attacker can send Modbus packets to manipulate register values that are inputs to the odorant injection logic such that too much or too little odorant is injected into a gas line.
Mitigation
GPL Odorizers recommends users update to the latest software version of the GPL750 in connection with the latest firmware from Horner Automation for the XL4, XL4 Prime, XL7, and XL7 Prime devices.https://lincenergysystems-my.sharepoint.com/:f:/p/h_baer/IgDYaHIhXpyLQJvnKPd6b80TAUgV7Lp8qmVYBFUb0lmr7ak?e=JLeADm.

Mitigation
GPL Odorizers recommends users clear the old files from their microSD cards, keeping only the LOGS folder and the FIRMWARE.LIC file if they have a WebMI license. The compressed folder downloaded from the link above can then be extracted to the root directory of the microSD card. These files already include the corresponding firmware update. If users do not have IT permissions to access their microSD cards, GPL Odorizers can provide preconfigured SD cards that technicians can simply swap into their odorizers prior to installation.
Mitigation
For assistance in updating GPL Odorizers to the latest version, users should reach out to GPL Odorizers directly via phone number (303) 697-6701 during the hours of 8:00 a.m. to 4:00 p.m. MST.

Successful exploitation of this vulnerability could allow an attacker to login as the PROG user and modify permissions.
The following versions of Yokogawa CENTUM VP are affected:
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 4 | Yokogawa | Yokogawa CENTUM VP | Use of Hard-coded Password |
Affected products contain a hardcoded password for the user account (PROG) used for CENTUM Authentication Mode within the system. Under the following conditions, there is a risk that an attacker could log in as the PROG user. The default permission for the PROG users is S1 permission (equivalent to OFFUSER). Therefore, for properly permission-controlled targets of operation and monitoring, even if an attacker logs in as the PROG user, the risk of critical operations or configuration changes being performed is considered low. If the PROG user's permissions have been changed for any reason, there is a risk that operations or configuration changes may be performed under the modified permissions. Additionally, exploiting this vulnerability requires an attacker to already have access to the HIS screen controls.
Mitigation
Yokogawa recommends users applying the following mitigations to affected versions:
Vendor fix
CENTUM VP R5.01.00 to R5.04.20: Change the user authentication mode to Windows Authentication Mode.
Vendor fix
CENTUM VP R6.01.00 to R6.12.00: Change the user authentication mode to Windows Authentication Mode.
Vendor fix
CENTUM VP R7.01.00: Apply patch software R7.01.10.
Mitigation
NOTE:Changing to Windows Authentication Mode requires engineering work. If users wish to make this change, please contact Yokogawa directly https://contact.yokogawa.com/cs/gw?c-id=000498.

Recommended security practices and firewall configurations can help protect a process control network from attacks that originate from outside the network. Such practices include that process control systems are physically protected from direct access by unauthorized personnel, have no direct connections to the Internet, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed, and others that have to be evaluated case by case. Process control systems should not be used for Internet surfing, instant messaging, or receiving e-mails. Portable computers and removable storage media should be carefully scanned for viruses before they are connected to a control system. Proper password policies and processes should be followed.

Operators of critical power systems (e.g. TSOs or DSOs) worldwide are usually required by regulations to build resilience into the power grids by applying multi-level redundant secondary protection schemes. It is therefore recommended that the operators check whether appropriate resilient protection measures are in place. The risk of cyber incidents impacting the grid's reliability can thus be minimized by virtue of the grid design. Siemens strongly recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product. If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment. As a general security measure Siemens strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN). It is advised to configure the environment according to our operational guidelines in order to run the devices in a protected IT environment. Recommended security guidelines can be found at: https://www.siemens.com/gridsecurity

Successful exploitation of this vulnerability could allow an attacker with access to the MAVLink interface to execute arbitrary shell commands without cryptographic authentication.
The following versions of PX4 Autopilot are affected:
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 9.8 | PX4 | PX4 Autopilot | Missing Authentication for Critical Function |
The MAVLink communication protocol does not require cryptographic authentication by default. When MAVLink 2.0 message signing is not enabled, any message -- including SERIAL_CONTROL, which provides interactive shell access -- can be sent by an unauthenticated party with access to the MAVLink interface. PX4 provides MAVLink 2.0 message signing as the cryptographic authentication mechanism for all MAVLink communication. When signing is enabled, unsigned messages are rejected at the protocol level.
Mitigation
PX4 recommends enabling MAVLink 2.0 message signing as the authentication mechanism for all non‑USB communication links. PX4 has published a security hardening guide for integrators and manufacturers at https://docs.px4.io/main/en/mavlink/security_hardening.

Schneider Electric recommends you work with your local field service representative or technical service consultant for further information.
https://buyautomation.se.com/
Mitigation
If users choose not to apply the remediation provided above, they should immediately apply the following mitigations to reduce the risk of exploit: The vulnerability is attacked with manipulated data from external sources to the DCS computers. Examples for these are: * Configuration taglists * DirectAccess Scripts * Any partial or full Galaxy backups * Library files * Code snippets * ASCII files of any sort * Generally, any file getting from outside the DCS computer on a DCS computer. Only use data from trusted sources, check for correct file name endings on data files, check for reasonable file sizes for any files coming to the system, and check structured data for any fields or columns which might be unexpected. Check for unusual manipulations of data within data files and reject files containing unexpected data or structures. Use secure communication channels and encrypt communications when communicating outside the site network. Avoid and ban removable media (e.g. USB sticks or drives) Minimize count of users with engineering or administrative rights to DCS computers and ensure all interactions on DCS computers are executed with minimal user access rights. Consequently, isolating Foxboro DCS computers will help minimizing the risk of this vulnerability being exploited.

Successful exploitation of these vulnerabilities could enable attackers to gain unauthorized administrative control over vulnerable charging stations or disrupt charging services through denial-of-service attacks.
The following versions of IGL-Technologies eParking.fi are affected:
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 9.4 | IGL-Technologies | IGL-Technologies eParking.fi | Missing Authentication for Critical Function, Improper Restriction of Excessive Authentication Attempts, Insufficient Session Expiration, Insufficiently Protected Credentials |
WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then issue or receive OCPP commands as a legitimate charger. Given that no authentication is required, this can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend.
Mitigation
IGL-Technologies has updated eParking's OCPP servers to reduce the risks posed by the vulnerability. These updates implemented the following security controls:
1) Enforce modern security profiles and stronger authentication.
2) Device‑level whitelisting was implemented to ensure that only authorized charging units can connect.
3) Rate‑limiting controls prevent excessive requests and reduces DoS risk.
4) Enhanced automated monitoring and alerting to detection abnormal network activity.
Devices using the encrypted deployment of eParking's OCPP servers or IGL-Technologies proprietary eTolppa protocol are not impacted by these vulnerabilities.
Mitigation
To prevent this in the future IGL-Technologies will continue vulnerability monitoring under their ISO 27001:2022 security program and tighten security requirements for future third‑party OCPP hardware approvals.

|---|---|---|---|
| 3.1 | 9.4 | CRITICAL | CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L |
The WebSocket Application Programming Interface lacks restrictions on the number of authentication requests. This absence of rate limiting may allow an attacker to conduct denial-of-service attacks by suppressing or mis-routing legitimate charger telemetry, or conduct brute-force attacks to gain unauthorized access.
Mitigation
IGL-Technologies has updated eParking's OCPP servers to reduce the risks posed by the vulnerability. These updates implemented the following security controls:

|---|---|---|---|
| 3.1 | 7.5 | HIGH | CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H |
The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. This vulnerability may allow unauthorized users to authenticate as other users or enable a malicious actor to cause a denial-of-service condition by overwhelming the backend with valid session requests.
Mitigation
IGL-Technologies has updated eParking's OCPP servers to reduce the risks posed by the vulnerability. These updates implemented the following security controls:

WebCTRL systems that communicate over BACnet inherit the protocol's lack of network layer authentication. WebCTRL does not implement additional validation of BACnet traffic so an attacker with network access could spoof BACnet packets directed at either the WebCTRL server or associated AutomatedLogic controllers. Spoofed packets may be processed as legitimate.
Mitigation
Automated Logic notes that WebCTRL 7 is End of Life (EOL) and has been out of support since January 27, 2023. Users are advised to upgrade to the latest version of the WebCTRL server application, which supports the more secure BACnet/SC.
Mitigation
For customers using supported versions of WebCTRL (WebCTRL 8.5 cumulative releases and later), Automated Logic provides secure configuration guidance for hardware and software deployments; BACnet Secure Connect (BACnet/SC) support, which introduces TLS encryption and mutual authentication; and published best practices for network segmentation, access control, and secure protocol implementation.

Service information is not encrypted when transmitted as BACnet packets over the wire, and can be sniffed, intercepted, and modified by an attacker. Valuable information such as the File Start Position and File Data can be sniffed from network traffic using Wireshark's BACnet dissector filter. The proprietary format used by WebCTRL to receive updates from the PLC can also be sniffed and reverse engineered.

Successful exploitation of these vulnerabilities could enable attackers to gain unauthorized administrative control over vulnerable charging stations or disrupt charging services through denial-of-service attacks.
The following versions of CTEK Chargeportal are affected:
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 9.4 | CTEK | CTEK Chargeportal | Missing Authentication for Critical Function, Improper Restriction of Excessive Authentication Attempts, Insufficient Session Expiration, Insufficiently Protected Credentials |
WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then issue or receive OCPP commands as a legitimate charger. Given that no authentication is required, this can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend.

The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. This vulnerability may allow unauthorized users to authenticate as other users or enable a malicious actor to cause a denial-of-service condition by overwhelming the backend with valid session requests.

Operators of critical power systems (e.g. TSOs or DSOs) worldwide are usually required by regulations to build resilience into the power grids by applying multi-level redundant secondary protection schemes. It is therefore recommended that the operators check whether appropriate resilient protection measures are in place. The risk of cyber incidents impacting the grid's reliability can thus be minimized by virtue of the grid design. Siemens strongly recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product. If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment.

Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is used, allows remote attackers (from the client side) to trigger unnecessarily expensive server-side DHE modular-exponentiation calculations. The client may cause asymmetric resource consumption. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE and validate the order of the public key.

An application trying to decrypt CMS messages encrypted using password based encryption can trigger an out-of-bounds read and write. Impact summary: This out-of-bounds read may trigger a crash which leads to Denial of Service for an application. The out-of-bounds write can cause a memory corruption which can have various consequences including a Denial of Service or Execution of attacker-supplied code. Although the consequences of a successful exploit of this vulnerability could be severe, the probability that the attacker would be able to perform it is low. Besides, password based (PWRI) encryption support in CMS messages is very rarely used. For that reason the issue was assessed as Moderate severity according to our Security Policy. The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue, as the CMS implementation is outside the OpenSSL FIPS module boundary.

The OpenSSL HTTP client API functions can be used directly by applications but they are also used by the OCSP client functions and CMP (Certificate Management Protocol) client implementation in OpenSSL. However the URLs used by these implementations are unlikely to be controlled by an attacker. In this vulnerable code the out of bounds read can only trigger a crash. Furthermore the vulnerability requires an attacker-controlled URL to be passed from an application to the OpenSSL function and the user has to have a 'no_proxy' environment variable set. For the aforementioned reasons the issue was assessed as Low severity. The vulnerable code was introduced in the following patch releases: 3.0.16, 3.1.8, 3.2.4, 3.3.3, 3.4.0 and 3.5.0. The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue, as the HTTP client implementation is outside the OpenSSL FIPS module boundary.

Improper Input Validation vulnerability in qs (parse modules) allows HTTP DoS.This issue affects qs: < 6.14.1. SummaryThe arrayLimit option in qs does not enforce limits for bracket notation (a[]=1&a[]=2), allowing attackers to cause denial-of-service via memory exhaustion. Applications using arrayLimit for DoS protection are vulnerable. DetailsThe arrayLimit option only checks limits for indexed notation (a[0]=1&a[1]=2) but completely bypasses it for bracket notation (a[]=1&a[]=2). Vulnerable code (lib/parse.js:159-162): if (root === '[]' && options.parseArrays) { obj = utils.combine([], leaf); // No arrayLimit check } Working code (lib/parse.js:175): else if (index <= options.arrayLimit) { // Limit checked here obj = []; obj[index] = leaf; } The bracket notation handler at line 159 uses utils.combine([], leaf) without validating against options.arrayLimit, while indexed notation at line 175 checks index <= options.arrayLimit before creating arrays. PoCTest 1 - Basic bypass: npm install qs const qs = require('qs'); const result = qs.parse('a[]=1&a[]=2&a[]=3&a[]=4&a[]=5&a[]=6', { arrayLimit: 5 }); console.log(result.a.length); // Output: 6 (should be max 5) Test 2 - DoS demonstration: const qs = require('qs'); const attack = 'a[]=' + Array(10000).fill('x').join('&a[]='); const result = qs.parse(attack, { arrayLimit: 100 }); console.log(result.a.length); // Output: 10000 (should be max 100) Configuration: * arrayLimit: 5 (test 1) or arrayLimit: 100 (test 2) * Use bracket notation: a[]=value (not indexed a[0]=value) ImpactDenial of Service via memory exhaustion. Affects applications using qs.parse() with user-controlled input and arrayLimit for protection. Attack scenario: * Attacker sends HTTP request: GET /api/search?filters[]=x&filters[]=x&...&filters[]=x (100,000+ times) * Application parses with qs.parse(query, { arrayLimit: 100 }) * qs ignores limit, parses all 100,000 elements into array * Server memory exhausted → application crashes or becomes unresponsive * Service unavailable for all users Real-world impact: * Single malicious request can crash server * No authentication required * Easy to automate and scale * Affects any endpoint parsing query strings with bracket notation

Axios is a promise based HTTP client for the browser and Node.js. When Axios starting in version 0.28.0 and prior to versions 0.30.2 and 1.12.0 runs on Node.js and is given a URL with the `data:` scheme, it does not perform HTTP. Instead, its Node http adapter decodes the entire payload into memory (`Buffer`/`Blob`) and returns a synthetic 200 response. This path ignores `maxContentLength` / `maxBodyLength` (which only protect HTTP responses), so an attacker can supply a very large `data:` URI and cause the process to allocate unbounded memory and crash (DoS), even if the caller requested `responseType: 'stream'`. Versions 0.30.2 and 1.12.0 contain a patch for the issue.

Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to versions 19.2.16, 20.3.14, and 21.0.1, there is a XSRF token leakage via protocol-relative URLs in angular HTTP clients. The vulnerability is a Credential Leak by App Logic that leads to the unauthorized disclosure of the Cross-Site Request Forgery (XSRF) token to an attacker-controlled domain. Angular's HttpClient has a built-in XSRF protection mechanism that works by checking if a request URL starts with a protocol (http:// or https://) to determine if it is cross-origin. If the URL starts with protocol-relative URL (//), it is incorrectly treated as a same-origin request, and the XSRF token is automatically added to the X-XSRF-TOKEN header. This issue has been patched in versions 19.2.16, 20.3.14, and 21.0.1. A workaround for this issue involves avoiding using protocol-relative URLs (URLs starting with //) in HttpClient requests. All backend communication URLs should be hardcoded as relative paths (starting with a single /) or fully qualified, trusted absolute URLs.

Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 21.0.2, 20.3.15, and 19.2.17, A Stored Cross-Site Scripting (XSS) vulnerability has been identified in the Angular Template Compiler. It occurs because the compiler's internal security schema is incomplete, allowing attackers to bypass Angular's built-in security sanitization. Specifically, the schema fails to classify certain URL-holding attributes (e.g., those that could contain javascript: URLs) as requiring strict URL security, enabling the injection of malicious scripts. This vulnerability is fixed in 21.0.2, 20.3.15, and 19.2.17.

Successful exploitation of this vulnerability could allow an attacker to execute malicious code with OS application service account permissions that the authenticated, privileged application user did not intend on running.
The following versions of Inductive Automation Ignition Software are affected:
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 6.3 | Inductive Automation | Inductive Automation Ignition Software | Deserialization of Untrusted Data |
A privileged Ignition user, intentionally or otherwise, imports an external file with a specially crafted payload, which executes embedded malicious code during deserialization.
Mitigation
Fix - upgrade Ignition software from 8.1.x to 8.3.0 or greater.
Mitigation
MITIGATION (8.1.x Linux). Implement Ignition Security Hardening Guide Appendix A. https://inductiveautomation.com/resources/article/ignition-security-hardening-guide
Mitigation
MITIGATION (8.1.x Windows). Covered in Ignition Security Hardening Guide Appendix A. 1. Create a new dedicated local Windows account that will be used exclusively for the Ignition service (e.g. svc-ign). a. The best security practice is that the Ignition service should not be a domain account (unless otherwise needed). b. Remove all group memberships from the service account (including Users and Administrators). c. Add to security policy to log in as a service. d. Add to "Deny log on locally" security policy. 2. Provide full read/write access only to the Ignition installation directory for the service account created in #1. a. Add read/write permissions to other directories in the local filesystem as needed (e.g.: if configured to use optional Enterprise Administration Module to write automated backups to the file system). 3. Set deny access settings for service account on other directories not needed by the Ignition service. a. Specifically the C:\Windows, C:\Users, and directories for any other applications in the Program Files or Program Files(x86) directories. b. Use java param to change temp directory to a location within the Ignition install directory so the Users folder can be denied access to the Ignition service account.
Mitigation
BEST PRACTICES (8.1.x and 8.3.x)4. Restrict project imports to verified and trusted sources only, ideally using checksums or digital signatures.5. Use multiple environments (e.g. Dev, Test, Prod) with a staging workflow so that new data is never introduced directly to Production environments. See Ignition Deployment Best Practices.6. When feasible, segment or isolate Ignition gateways from corporate resources and Windows Domains.a. The Ignition service account or AD server object should never need Windows Domain or Windows Active Directory privileges. This would only be needed if an Asset Owners IT or OT department uses this for management outside Ignition.b. Ignition may be federated with Active Directory environments (e.g. OT domains) by entering "Authentication Profile" credentials within the Ignition gateway itself. This could use secure LDAP, SAML, or OpenID Connect.7. When feasible, enforce strong credential management and MFA for all users with Designer permissions (8.1.x and 8.3.x), Config Page permissions (8.1.x), and Config Write permissions (8.3.x).8. When feasible, deploy Ignition within hardened or containerized environments.

Successful exploitation of this vulnerability could allow an unauthorized attacker to access controller management settings, control components, disclose information, or cause a denial-of-service condition.
The following versions of Honeywell IQ4 Series BMS Controller (Update A) are affected:
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 9.8 | Honeywell | Honeywell IQ4 Series BMS Controller (Update A) | Missing Authentication for Critical Function |
Prior to version 3.30, Honeywell IQ4 Series of building management controllers expose a web-based HMI without authentication in its factory-default configuration. With no user module configured, the system operates under a System Guest (level 100) context, granting read/write privileges to any party able to reach the HTTP interface. Authentication controls are enforced after a web user is created during commissioning, which dynamically enables the user module. Because this function is accessible prior to authentication, a remote user can create a new account with administrative read/write permissions enabling the user module and imposing authentication under attacker-controlled credentials. This action can effectively lock legitimate users out of the controller.
Mitigation
Version 3.30, released June 2015, and later force users to install a user module upon the commissioning of the device. This user module enables authentication and other security features for the web interface. When updating previously commissioned devices to firmware versions 3.30 or later, users are not forced to install a user module unless they have changed their device configuration files after updating the firmware version. Honeywell recommends that users check their firmware versions and ensure that a user module has been set up to enable device security features, even if they are running firmware version 3.30 or later.
Mitigation
Apply product updates as available.
Mitigation
Follow guidance in the product security manual to ensure isolation of network segments hosting building automation controllers.
Mitigation
Ensure adequate security controls are in place between OT and IT segments.
Mitigation

Successful exploitation of these vulnerabilities could enable attackers to gain unauthorized administrative control over vulnerable charging stations or disrupt charging services through denial-of-service attacks.
The following versions of Everon OCPP Backends are affected:
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 9.4 | Everon | Everon OCPP Backends | Missing Authentication for Critical Function, Improper Restriction of Excessive Authentication Attempts, Insufficient Session Expiration, Insufficiently Protected Credentials |
WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then issue or receive OCPP commands as a legitimate charger. Given that no authentication is required, this can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend.

Recommended security practices and firewall configurations can help protect a process control network from attacks that originate from outside the network. Such practices include that process control systems are physically protected from direct access by unauthorized personnel, have no direct connections to the Internet, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed, and others that have to be evaluated case by case. Process control systems should not be used for Internet surfing, instant messaging, or receiving e-mails. Portable computers and removable storage media should be carefully scanned for viruses before they are connected to a control system. Proper password policies and processes should be followed.

Successful exploitation of these vulnerabilities could enable attackers to gain unauthorized administrative control over vulnerable charging stations or disrupt charging services through denial-of-service attacks.
The following versions of Mobiliti e-mobi.hu are affected:
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 9.4 | Mobiliti | Mobiliti e-mobi.hu | Missing Authentication for Critical Function, Improper Restriction of Excessive Authentication Attempts, Insufficient Session Expiration, Insufficiently Protected Credentials |
WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then issue or receive OCPP commands as a legitimate charger. Given that no authentication is required, this can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend.

Successful exploitation of these vulnerabilities could allow attackers to impersonate charging stations, hijack sessions, suppress or misroute legitimate traffic to cause large-scale denial of service, and manipulate data sent to the backend.
The following versions of CloudCharge cloudcharge.se are affected:
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 9.4 | CloudCharge | CloudCharge cloudcharge.se | Missing Authentication for Critical Function, Improper Restriction of Excessive Authentication Attempts, Insufficient Session Expiration, Insufficiently Protected Credentials |
WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then issue or receive OCPP commands as a legitimate charger. Given that no authentication is required, this can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend.

|---|---|---|---|
| 3.1 | 9.4 | CRITICAL | CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L |
The WebSocket Application Programming Interface lacks restrictions on the number of authentication requests. This absence of rate limiting may allow an attacker to conduct denial-of-service attacks by suppressing or mis-routing legitimate charger telemetry, or conduct brute-force attacks to gain unauthorized access.

|---|---|---|---|
| 3.1 | 7.5 | HIGH | CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H |
The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. This vulnerability may allow unauthorized users to authenticate as other users or enable a malicious actor to cause a denial-of-service condition by overwhelming the backend with valid session requests.
