Siemens Issues Security Updates for Multiple Industrial and Engineering Products
Siemens published security advisories for multiple products, prompting both CISA ICS advisories and a Canadian Centre for Cyber Security alert covering a broad set of affected industrial/engineering software and OT-adjacent components. Reported issues include a stored XSS in Siemens Polarion (CVE-2025-40587; CVSS 7.6) where authenticated users can inject JavaScript via crafted document titles, and local privilege escalation paths in Siemens SINEC NMS and its User Management Component (UMC) (CVE-2026-25655, CVE-2026-25656; CVSS 7.8) that allow low-privileged users to modify configuration/search paths to load malicious DLLs and potentially gain elevated execution (including SYSTEM-level impact). Siemens also addressed a missing authorization condition affecting Siveillance Video Management Servers Webhooks/MIP Webhooks API (CVSS 6.3), enabling a read-only user to obtain full API access.
Additional advisories cover file-parsing and third-party component risks that can lead to crashes or potential code execution. Siemens NX is affected by multiple CGM file parsing flaws (CVE-2026-22923/22924/22925; CVSS 7.8) that can be triggered when a user opens a malicious file, and Siemens Solid Edge includes an out-of-bounds read in the PS/IGES Parasolid translator when processing crafted IGS files (CVSS 7.8). Desigo CC and SENTRON Powermanager are impacted via the third-party WIBU Systems CodeMeter Runtime chain tied to CVE-2023-38545 (curl SOCKS5 heap overflow; CVSS 8.8), with Siemens providing component update instructions. Siemens SINEC OS before V3.3 aggregates a large set of third-party CVEs across supported platforms, and Siemens COMOS advisories include multiple issues (up to CVSS 10) spanning potential code execution, DoS, data exposure, and access control violations; Siemens recommends updating where fixes are available and applying countermeasures where they are not yet released.
