Vulnerability from variot

An exploitable command injection vulnerability exists in the iocheckd service ‘I/O-Check’ function of the WAGO PFC 200 version 03.02.02(14). An attacker can send a specially crafted XML cache file At 0x1e8a8 the extracted domainname value from the xml file is used as an argument to /etc/config-tools/edit_dns_server domain-name= using sprintf().This command is later executed via a call to system(). (DoS) It may be put into a state. WAGO PFC200 is a programmable logic controller (PLC) from German WAGO company
