EPSS · scored 2026-10-27

A vulnerability has been identified in SINEC NMS (All versions >= V1.0.3 < V2.0), SINEC NMS (All versions < V1.0.3), SINEMA Server V14 (All versions). The affected software do not properly check privileges between users during the same web browser session, creating an unintended sphere of control. This could allow an authenticated low privileged user to achieve privilege escalation.

  • SSA-250085SSA-250085: Multiple Vulnerabilities in SINEC NMS and SINEMA Server2022-03-08csaf · siemens_psirtDE

    SINEC NMS and SINEMA Server V14 contain multiple vulnerabilities that could allow an attacker to execute arbitrary code on the system, arbitrary commands on the local database or achieve privilege escalation. Siemens has released several updates for SINEC NMS and recommends to update to the latest version. Siemens recommends specific countermeasures for products where updates are not, or not yet available.
