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 hostname values that are greater than 1024-len(‘/etc/config-tools/change_hostname hostname=‘) in length. A hostname value of length 0x3fd will cause the service to crash.

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 nombre de host que sea mayor que 1024-len (‘/etc/config-tools/change_hostname hostname=‘) en longitud.
