Descriptions

An exploitable command injection vulnerability exists in the iocheckd service ‘I/O-Check’ function of the WAGO PFC 200 Firmware 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 0x1ea28 the extracted type value from the xml file is used as an argument to /etc/config-tools/config_interfaces interface=X1 state=enabled config-type=<contents of type node> using sprintf(). This command is later executed via a call to system().

Se presenta una vulnerabilidad de inyección de comando explotable en la función "I/O-Check" del servicio iocheckd de WAGO PFC 200 en la versión de firmware 03.02.02(14). Un archivo cache XML especialmente diseñado escrito en una ubicación específica en el dispositivo puede ser usado para inyectar comandos de Sistema Operativo. Un atacante puede enviar un paquete especialmente diseñado para activar el análisis de este archivo cache.
