An exploitable stack buffer overflow vulnerability exists in the iocheckd service ‘I/O-Check’ functionality of WAGO PFC 200 version 03.02.02(14). A specially crafted XML cache file written to a specific location on the device can cause a stack buffer overflow, resulting in code execution. An attacker can send a specially crafted packet to trigger the parsing of this cache file.
