CVE-2024-39567 Siemens CVE debrief

CVE-2024-39567 is a high-severity command injection vulnerability in Siemens SINEMA Remote Connect Client, published on July 9, 2024. The vulnerability exists in the system service due to missing server-side input sanitization when loading VPN configurations. An authenticated local attacker can exploit this flaw to execute arbitrary code with system privileges. The CVSS 3.1 score of 7.8 reflects high impacts to confidentiality, integrity, and availability. Siemens has released a vendor fix in version 3.2 HF1 or later. Organizations should prioritize patching given the local privilege escalation risk and system-level code execution capability.

Who should care

Organizations operating Siemens SINEMA Remote Connect Client in industrial environments, OT security teams managing remote access VPN infrastructure, and asset owners with distributed industrial control systems requiring secure remote connectivity.

Technical summary

The SINEMA Remote Connect Client system service fails to sanitize input when loading VPN configurations, creating a command injection vulnerability. An authenticated attacker with local access can inject malicious commands through crafted configuration data, resulting in arbitrary code execution with system-level privileges. The attack requires local access and valid authentication but does not require user interaction. The vulnerability affects confidentiality, integrity, and availability with high impact across all three dimensions.

Defensive priority

high

Recommended defensive actions

  • Apply vendor fix: Update SINEMA Remote Connect Client to version 3.2 HF1 or later
  • Validate VPN configuration sources and restrict configuration file permissions
  • Implement principle of least privilege for local user accounts
  • Monitor for anomalous system service behavior and unexpected process execution
  • Review and apply CISA ICS recommended practices for industrial control systems defense in depth

Evidence notes

Vulnerability confirmed through CISA ICS advisory ICSA-24-193-15 and Siemens security advisory SSA-868282. Command injection vector specifically tied to VPN configuration loading without input sanitization. Authentication and local access requirements confirmed in source documentation.
