Nome do software vulnerável e versões afetadas: Versões do OPUPI0 AMQP/MQTT anteriores à V5.30 Descrição: Foi identificada uma vulnerabilidade que permite que um invasor com acesso remoto ao shell ou acesso físico obtenha credenciais devido à proteção insuficiente das senhas de clientes MQTT armazenadas, levando à perda de confidencialidade. O problema está relacionado ao armazenamento de informações confidenciais sem criptografia. Recomendações: Para versões anteriores à V5.30, atualize para a versão V5.30 ou posterior para resolver o problema. Como solução temporária, considere restringir o acesso ao dispositivo para minimizar o risco de exploração. Evite usar o dispositivo até que o problema seja resolvido.

**Name of the Vulnerable Software and Affected Versions** CP-8031 MASTER MODULE versions prior to CPCI85 V05 CP-8050 MASTER MODULE versions prior to CPCI85 V05 **Description** A vulnerability has been identified that involves an exposed UART console login interface. This issue could allow an attacker with direct physical access to attempt bruteforcing or cracking the root password to gain login access to the device. The vulnerability is related to the web server software of the Siemens SICAM processor control modules, specifically affecting the CP-8031 and CP-8050 models. Exploitation of this vulnerability may enable an attacker to elevate their privileges to the root level. **Recommendations** For CP-8031 MASTER MODULE versions prior to CPCI85 V05, consider restricting physical access to the device to prevent potential bruteforcing or password cracking attempts until a patch or update is available. For CP-8050 MASTER MODULE versions prior to CPCI85 V05, consider restricting physical access to the device to prevent potential bruteforcing or password cracking attempts until a patch or update is available. As a temporary workaround, consider disabling the UART console login interface on both CP-8031 and CP-8050 MASTER MODULEs to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** CP-8031 MASTER MODULE versions prior to CPCI85 V05 CP-8050 MASTER MODULE versions prior to CPCI85 V05 **Description** A vulnerability has been identified in the web interface of affected devices due to missing server-side input sanitation, making it vulnerable to command injection. This could allow an authenticated privileged remote attacker to execute arbitrary code with root privileges. **Recommendations** For CP-8031 MASTER MODULE versions prior to CPCI85 V05, update to version CPCI85 V05 or later to resolve the issue. For CP-8050 MASTER MODULE versions prior to CPCI85 V05, update to version CPCI85 V05 or later to resolve the issue. As a temporary workaround, consider restricting access to the web interface of affected devices to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** CP-8031 MASTER MODULE versions prior to CPCI85 V05 CP-8050 MASTER MODULE versions prior to CPCI85 V05 **Description** A vulnerability has been identified that involves the use of hard-coded credentials in the firmware of the affected devices. This could allow an attacker with direct physical access to exploit the vulnerability for UART console login to the device, potentially leading to privilege escalation. **Recommendations** For CP-8031 MASTER MODULE versions prior to CPCI85 V05, update to version CPCI85 V05 or later to resolve the issue. For CP-8050 MASTER MODULE versions prior to CPCI85 V05, update to version CPCI85 V05 or later to resolve the issue. As a temporary workaround, consider restricting physical access to the devices until a patch is applied.

**Name of the Vulnerable Software and Affected Versions** CP-8031 MASTER MODULE versions prior to CPCI85 V05 CP-8050 MASTER MODULE versions prior to CPCI85 V05 **Description** The issue is related to insufficient argument checking in the web server of the Siemens SICAM CP-8031 and CP-8050 processor control modules. This can be exploited by a remote attacker to execute arbitrary commands via the web server port 443/tcp if the `Remote Operation` parameter is enabled. By default, the `Remote Operation` parameter is disabled. The vulnerability could allow an unauthenticated remote attacker to perform arbitrary code execution on the device. **Recommendations** For CP-8031 MASTER MODULE versions prior to CPCI85 V05, update to version CPCI85 V05 or later to resolve the issue. For CP-8050 MASTER MODULE versions prior to CPCI85 V05, update to version CPCI85 V05 or later to resolve the issue. As a temporary workaround, consider disabling the `Remote Operation` parameter to minimize the risk of exploitation.
