Name of the Vulnerable Software and Affected Versions: CIRCUTOR TCP2RS+ version 1.3b Description: The issue allows an attacker to modify any configuration value without authentication by sending packets through the UDP protocol and port 2000, deconfiguring the device and thus disabling its use, even if the device has the user/password authentication option enabled. This equipment is at the end of its useful life cycle. Recommendations: For version 1.3b, as a temporary workaround, consider restricting access to the UDP protocol and port 2000 until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: CIRCUTOR Q-SMT version 1.0.4 Description: An attacker with access to the network where the CIRCUTOR Q-SMT is located could obtain legitimate credentials or steal sessions due to the fact that the device only implements the HTTP protocol, preventing a secure communication channel from being established. Recommendations: For version 1.0.4, consider disabling the use of the HTTP protocol until a patch is available, and restrict access to sensitive data to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

This is possible even if the device has the user/password authentication option enabled. The equipment is at the end of its useful life cycle. Recommendations: For version 1.3b, consider restricting access to port 2000 to minimize the risk of exploitation, and avoid using the UDP protocol for configuration changes until a fix is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** SOCOMEC MODULYS GP Netvision versions 7.20 and prior **Description** The issue is related to weak encryption for credentials on HTTP connections, which could allow threat actors to obtain sensitive information. **Recommendations** For SOCOMEC MODULYS GP Netvision versions 7.20 and prior, consider disabling HTTP connections or restricting access to sensitive information until a fix is available. As a temporary workaround, avoid using HTTP connections for transmitting credentials.
