CVE-2024-41904 Siemens CVE debrief

CVE-2024-41904 is a HIGH severity (CVSS 7.5) authentication weakness in Siemens SINEC Traffic Analyzer (6GK8822-1BG01-0BA0), published 2024-08-13. The affected application fails to enforce restrictions on excessive authentication attempts, enabling unauthenticated attackers to conduct brute force attacks against legitimate user credentials or keys. The vulnerability is network-exploitable with low attack complexity, requiring no privileges or user interaction. Siemens has released a vendor fix: update to V2.0 or later version. CISA published advisory ICSA-24-228-04 on the same date as the CVE publication. No known exploitation in ransomware campaigns has been reported, and the vulnerability is not listed in CISA's Known Exploited Vulnerabilities catalog.

Who should care

Organizations operating Siemens SINEC Traffic Analyzer in industrial network environments, OT security teams, ICS asset owners, and critical infrastructure operators relying on network traffic monitoring for operational visibility should prioritize this vulnerability. The unauthenticated exploitation path and high confidentiality impact pose significant risk to network segmentation strategies and sensitive operational data. Organizations subject to NERC CIP, IEC 62443, or similar industrial cybersecurity frameworks should assess exposure and apply compensating controls pending patch deployment.

Technical summary

The SINEC Traffic Analyzer application does not implement adequate rate limiting or account lockout mechanisms to prevent excessive authentication attempts. An unauthenticated remote attacker can exploit this weakness to systematically guess user credentials or keys through automated brute force attacks. The vulnerability is classified as HIGH severity due to the potential for unauthorized access to network traffic analysis data and system configuration. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) indicates network attack vector, low complexity, no required privileges or user interaction, and high confidentiality impact with no integrity or availability impact.

Defensive priority

HIGH

Recommended defensive actions

  • Apply vendor fix: Update SINEC Traffic Analyzer to V2.0 or later version
  • Implement network segmentation to limit exposure of SINEC Traffic Analyzer to untrusted networks
  • Monitor for anomalous authentication patterns and repeated failed login attempts
  • Review and enforce strong password policies and consider multi-factor authentication where supported
  • Apply CISA ICS recommended practices for defense-in-depth strategies
