Summary

SINEC Traffic Analyzer versions prior to 3.0 contain multiple memory corruption and privilege escalation vulnerabilities (CVE-2024-24989, CVE-2024-24990, CVE-2025-40766, CVE-2025-40767, CVE-2025-40768, CVE-2025-40769) that allow a local user to execute arbitrary code with elevated privileges. Additionally, CVE-2025-40770 affects all versions with no fix currently available. Siemens has released version 3.0 to address the first six CVEs but indicates CVE-2025-40770 remains unresolved.

What this means
What could happen
Multiple vulnerabilities in SINEC Traffic Analyzer could allow an attacker with local access and low privileges to execute arbitrary code with elevated permissions, potentially disrupting traffic management systems or data integrity in transportation networks.
Who's at risk
Transportation network operators and traffic management system administrators who deploy Siemens SINEC Traffic Analyzer should prioritize this vulnerability. Any traffic monitoring or control devices running SINEC Traffic Analyzer before version 3.0, or using version 6GK8822-1BG01-0BA0 for the unpatched CVE-2025-40770, are at risk.
How it could be exploited
An attacker with local system access and low-level user privileges could exploit memory corruption (CWE-476, CWE-416) or privilege escalation vulnerabilities (CWE-250) to gain elevated code execution. The attack requires local presence on the device—the high complexity rating suggests exploitation requires specific conditions or knowledge of the system state.
Prerequisites
  • Local access to the SINEC Traffic Analyzer device
  • Low-level user account credentials on the system
  • Knowledge of specific system conditions or configurations to trigger the vulnerability (high complexity)

SINEC Traffic Analyzer
HOTFIXUpdate SINEC Traffic Analyzer (6GK8822-1BG01-0BA0) to version 3.0 or later to address CVE-2024-24989, CVE-2024-24990, CVE-2025-40766, CVE-2025-40767, CVE-2025-40768, and CVE-2025-40769
Long-term hardening
0/2
SINEC Traffic Analyzer
HARDENINGPlace the SINEC Traffic Analyzer behind a firewall and isolate it from the business network to minimize local access opportunities from untrusted users
HARDENINGDisable or restrict unnecessary network services and management interfaces on the SINEC Traffic Analyzer to reduce the attack surface
