CVE-2017-9947: A vulnerability has been identified in Siemens APOGEE PXC and TALON TC BACnet Automation Controllers in all...

A vulnerability has been identified in Siemens APOGEE PXC and TALON TC BACnet Automation Controllers in all versions <V3.5. A directory traversal vulnerability could allow a remote attacker with network access to the integrated web server (80/tcp and 443/tcp) to obtain information on the structure of the file system of the affected devices.

Security readout for executives and security teams

Siemens APOGEE PXC and TALON TC BACnet controllers below V3.5 may expose file-system structure information through their web server. This is not described as system takeover, but it can help attackers map building automation devices and prepare follow-on attacks. Exposure is most likely where affected building automation controllers are reachable on corporate, facilities, vendor remote-access, or internet-facing networks via HTTP or HTTPS. The source bundle identifies APOGEE PXC and TALON TC BACnet Automation Controllers in all versions below V3.5. Prioritize remediation for exposed or remotely reachable building automation environments. The direct impact is information disclosure, but building control systems have operational importance and exposed management interfaces create avoidable risk. Mitigation focus: Inventory APOGEE PXC and TALON TC BACnet controllers and firmware versions.; Follow Siemens SSA-148078 guidance for affected versions below V3.5.; Restrict TCP 80 and 443 access to trusted management networks only..
