VAR-202003-0692
Vulnerability from variot - Updated: 2023-12-18 12:27An exploitable command injection vulnerability exists in the iocheckd service ‘I/O-Check’ function of the WAGO PFC 200 version 03.02.02(14). A specially crafted XML cache file written to a specific location on the device can be used to inject OS commands. An attacker can send a specially crafted packet to trigger the parsing of this cache file.At 0x1e9fc the extracted subnetmask value from the xml file is used as an argument to /etc/config-tools/config_interfaces interface=X1 state=enabled subnet-mask= 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. The vulnerability stems from the fact that the network system or product did not properly filter the special characters, commands, etc. during the process of constructing the executable command of the operating system by external input data. An attacker could use this vulnerability to execute illegal operating system commands
