CVE-2024-41681 Siemens CVE debrief

A medium-severity vulnerability in Siemens Location Intelligence family products allows unauthenticated on-path attackers to read and modify data due to weak default cipher configurations. Published August 13, 2024, this issue affects the web server component of affected products. The attack requires adjacent network access, high attack complexity, and user interaction, but successful exploitation enables confidentiality loss and high-impact integrity/availability compromise. Siemens has released version 4.4 as a remediation. No known exploitation in ransomware campaigns has been reported.

Who should care

Organizations operating Siemens Location Intelligence family products in industrial environments, particularly those with web-facing or network-accessible deployments. Security teams responsible for TLS/SSL configuration management and industrial control system defense should prioritize this update.

Technical summary

The web server in Siemens Location Intelligence family products ships with weak cipher suites enabled by default. An unauthenticated attacker positioned on the network path between legitimate clients and the affected device can exploit this configuration to perform a man-in-the-middle attack, decrypting and modifying traffic. The CVSS 3.1 score of 6.7 reflects adjacent network access requirements, high attack complexity, and necessary user interaction, with potential for high impact on integrity and availability. Proof-of-concept exploitation has been reported. Siemens provides version 4.4 as the vendor fix.

Defensive priority

medium

Recommended defensive actions

  • Update Siemens Location Intelligence family products to version 4.4 or later to address weak cipher configurations
  • Review TLS/SSL cipher suite configurations on affected systems to ensure only strong ciphers are enabled
  • Implement network segmentation to limit exposure of affected devices to untrusted networks
  • Monitor for anomalous network traffic patterns that may indicate on-path attack attempts
  • Apply defense-in-depth strategies per CISA ICS recommended practices for industrial control systems
