CVE-2024-47808 Siemens CVE debrief

CVE-2024-47808 is a high-severity vulnerability in Siemens SINEC NMS, published on November 12, 2024. The affected application contains a database function that fails to properly restrict user permissions for writing to the host filesystem. An authenticated attacker with medium privileges can exploit this flaw to write arbitrary content to any location on the host filesystem, potentially leading to complete system compromise. The vulnerability carries a CVSS 3.1 score of 8.4 (HIGH severity) with the vector AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H, indicating local attack vector, low attack complexity, low privileges required, no user interaction, changed scope, and high impact to integrity and availability. Siemens has released a vendor fix: users should update to SINEC NMS V3.0 SP1 or later. CISA has coordinated disclosure through advisory ICSA-24-319-04.

Who should care

Organizations operating Siemens SINEC NMS for industrial network management, particularly in critical infrastructure environments. Security teams responsible for OT/ICS asset protection, database administrators managing SINEC NMS deployments, and compliance officers tracking industrial cybersecurity standards should prioritize this vulnerability for remediation.

Technical summary

The vulnerability exists in a database function within SINEC NMS that lacks proper permission restrictions for filesystem write operations. Authenticated users with medium privileges can leverage this function to write arbitrary content to any path on the host filesystem. This represents a significant security boundary violation in an industrial network management system, as filesystem write capabilities can enable further compromise including configuration tampering, malware deployment, or denial of service. The attack requires local access or existing authenticated session, with low complexity for exploitation.

Defensive priority

high

Recommended defensive actions

  • Update Siemens SINEC NMS to V3.0 SP1 or later version as specified in vendor security advisory
  • Review and restrict database user permissions to enforce principle of least privilege
  • Monitor filesystem write operations for unauthorized or anomalous activity
  • Apply network segmentation to limit access to SINEC NMS management interfaces
  • Follow CISA ICS recommended practices for defense-in-depth strategies
