https://notcve.org/view.php?id=CVE-2023-42796
A vulnerability has been identified in CP-8031 MASTER MODULE (All versions < CPCI85 V05.11), CP-8050 MASTER MODULE (All versions < CPCI85 V05.11). The web server of affected devices fails to properly sanitize user input for the /sicweb-ajax/tmproot/ endpoint. This could allow an authenticated remote attacker to traverse directories on the system and download arbitrary files. By exploring active session IDs, the vulnerability could potentially be leveraged to escalate privileges to the administrator role. Se ha identificado una vulnerabilidad en: CP-8031 MASTER MODULE (Todas las versiones < CPCI85 V05.11), CP-8050 MASTER MODULE (Todas las versiones < CPCI85 V05.11). El servidor web de los dispositivos afectados no sanitiza adecuadamente la entrada del usuario para el endpoint /sicweb-ajax/tmproot/. Esto podría permitir que un atacante remoto autenticado atraviese directorios del sistema y descargue archivos arbitrarios. • https://cert-portal.siemens.com/productcert/pdf/ssa-770890.pdf • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2023-28489
A vulnerability has been identified in CP-8031 MASTER MODULE (All versions < CPCI85 V05), CP-8050 MASTER MODULE (All versions < CPCI85 V05). Affected devices are vulnerable to command injection via the web server port 443/tcp, if the parameter “Remote Operation” is enabled. The parameter is disabled by default. The vulnerability could allow an unauthenticated remote attacker to perform arbitrary code execution on the device. • http://packetstormsecurity.com/files/173370/Siemens-A8000-CP-8050-CP-8031-Code-Execution-Command-Injection.html http://seclists.org/fulldisclosure/2023/Jul/14 https://cert-portal.siemens.com/productcert/pdf/ssa-472454.pdf • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
