Siemens SINEC NMS
Summary
Multiple Siemens SINEC NMS products are affected by local privilege escalation vulnerabilities, specifically CVE-2026-25655 and CVE-2026-25656. A low-privileged attacker could exploit these vulnerabilities to load malicious DLLs and achieve arbitrary code execution with elevated privileges; Siemens has released updates to address these issues.
IFF Assessment
Privilege escalation vulnerabilities in Siemens SINEC NMS products allow attackers to potentially gain elevated privileges and execute arbitrary code.
Severity
Defender Context
Defenders need to prioritize patching Siemens SINEC NMS installations to version 4.0 SP2 or later to mitigate the risk of local privilege escalation. Monitor systems for suspicious DLL loading activity, especially from low-privileged accounts. This type of vulnerability is common in software that runs with elevated privileges and has improper file handling.
