CVE-2019-5178
https://notcve.org/view.php?id=CVE-2019-5178
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. 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). • https://talosintelligence.com/vulnerability_reports/TALOS-2019-0963 • CWE-787: Out-of-bounds Write •

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 0x1e87c the extracted hostname value from the xml file is used as an argument to /etc/config-tools/change_hostname hostname=<contents of hostname node> using sprintf(). This command is later executed via a call to system().
