"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.

This plugin only works with Tenable.ot.
