Descriptions

An exploitable stack buffer overflow vulnerability vulnerability exists in the iocheckd service ‘I/O-Check’ functionality of WAGO PFC 200 Firmware version 03.02.02(14). An attacker can send a specially crafted packet to trigger the parsing of this cache file. The destination buffer sp+0x440 is overflowed with the call to sprintf() for any ip values that are greater than 1024-len(‘/etc/config-tools/config_interfaces interface=X1 state=enabled ip-address=‘) in length. A ip value of length 0x3da will cause the service to crash.

Se presenta una vulnerabilidad de desbordamiento del búfer de la pila explotable en la funcionalidad "I-O-Check" del servicio iocheckd de WAGO PFC 200, versiones de Firmware 03.02.02(14). Un atacante puede enviar un paquete especialmente diseñado para activar el análisis de este archivo cache. El búfer de destino sp+0x440 es desbordado con la llamada a la función sprintf() para cualquier valor de IP que sea mayor que 1024-len(‘/etc/config-tools/config_interfaces interface=X1 state=enabled ip-address=‘) en longitud. Un valor de ip de longitud 0x3da causará el bloqueo del servicio.
