Detection & IOCsextracted from sources · hover to see the quote
- →CVE-2025-40735 is an unauthenticated SQL injection vulnerability in Siemens SINEC NMS (all versions prior to V4.0); monitor for anomalous or unsolicited SQL query patterns in traffic directed at SINEC NMS endpoints from unauthenticated sources. ↗
- →CVE-2025-40735 carries CVSS v3.1 score 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H); prioritize detection of low-complexity, network-accessible exploitation attempts requiring only low privileges against SINEC NMS. ↗
- →All Siemens SINEC NMS deployments running versions prior to V4.0 are affected; inventory and flag any such instances exposed to network access as high-priority targets for patching and monitoring. ↗
- ·No known public exploitation has been reported at time of advisory publication; no public proof-of-concept or exploit code is referenced in available sources. ↗
- ·The advisory covers multiple CVEs (CVE-2025-40735 through CVE-2025-40738) for SINEC NMS; CVE-2025-40735 is specifically the SQL injection; the other CVEs (missing auth, path traversal) are distinct vulnerabilities in the same product and should not be conflated in detection logic. ↗
