CVE-2014-0769: Festo CECX-X-(C1/M1) Controller Improper Authentication

The Festo CECX-X-C1 Modular Master Controller with CoDeSys and CECX-X-M1 Modular Controller with CoDeSys and SoftMotion do not require authentication for connections to certain TCP ports, which allows remote attackers to (1) modify the configuration via a request to the debug service on port 4000 or (2) delete log entries via a request to the log service on port 4001.

Security readout for executives and security teams

Certain Festo industrial controllers expose services that do not require authentication. A remote attacker who can reach the affected ports could change controller configuration or delete logs, creating operational and investigation risk for industrial environments. Exposure is most likely where these legacy Festo controllers remain deployed and TCP ports 4000 or 4001 are reachable from untrusted networks, business networks, remote access paths, or poorly segmented industrial networks. Treat this as a high-priority industrial control exposure if the affected controllers are present. The business concern is unauthorized process configuration change plus loss of device log evidence, not general IT data theft. Mitigation focus: Identify any CECX-X-C1 or CECX-X-M1 controllers in production.; Restrict access to TCP ports 4000 and 4001 to trusted engineering hosts.; Segment affected controllers from business, internet, and vendor remote-access paths..

Improper Authentication

Improper Authentication represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
