A vulnerability has been identified in SIMATIC RTLS Locating Manager (All versions < V2.10.2). The directory of service executables of the affected application could allow a local attacker to include arbitrary commands that are executed with SYSTEM privileges when the system restarts.

Weakness

During installation, installed file permissions are set to allow anyone to modify those files.

Affected Software

Name Vendor Start Version End Version
Simatic_rtls_locating_manager Siemens * 2.10.2 (excluding)

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
