CVE-2024-47563 Siemens CVE debrief

CVE-2024-47563 is a path traversal vulnerability in Siemens SINEC Security Monitor that allows unauthenticated remote attackers to create files outside intended directories via a CSR file creation endpoint. The vulnerability stems from improper validation of file paths supplied to this endpoint, enabling attackers to compromise file integrity in writable directories. Published October 8, 2024, this medium-severity issue (CVSS 5.3) was last modified March 12, 2026, when CISA republished the advisory based on updated Siemens ProductCERT guidance. Siemens has released version 4.9.0 to address this vulnerability.

Who should care

Organizations operating Siemens SINEC Security Monitor in industrial environments, OT security teams managing network security monitoring infrastructure, and asset owners responsible for maintaining integrity of security monitoring systems should prioritize this remediation.

Technical summary

The SINEC Security Monitor application fails to properly sanitize file paths provided to an endpoint designed for Certificate Signing Request (CSR) file creation. An unauthenticated remote attacker can supply malicious path sequences (e.g., ../) to traverse outside the intended directory structure and create files in any writable location accessible to the application. This compromises file integrity in those directories. The attack requires no authentication, has low complexity, and is exploitable over the network. The vulnerability is classified as CWE-22 (Improper Limitation of a Pathname to a Restricted Directory).

Defensive priority

Recommended defensive actions

  • Apply Siemens SINEC Security Monitor version 4.9.0 or later to remediate the path traversal vulnerability
  • Restrict network access to SINEC Security Monitor administrative interfaces to trusted hosts only
  • Monitor file system integrity in writable directories used by SINEC Security Monitor for unauthorized file creation
  • Review and implement CISA ICS recommended practices for industrial control system defense in depth
  • Validate that CSR file creation endpoints are not exposed to untrusted networks

Evidence notes

CISA ICS advisory ICSA-24-284-06 published October 8, 2024, with subsequent revisions through March 12, 2026. Siemens ProductCERT advisory SSA-430425 provides vendor remediation guidance. CVSS 3.1 vector confirms network-accessible, low-complexity attack with no privileges required.
