Name of the Vulnerable Software and Affected Versions WAGO PFC200 Firmware versions 03.00.39(12) through 03.02.02(14)

Description An exploitable command injection issue exists in the Cloud Connectivity functionality. An attacker can inject OS commands into the TimeoutUnconfirmed parameter value contained in the Firmware Update command.
