GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

VAR-202003-0696

Vulnerability from variot - Updated: 2023-12-18 12:43

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. WAGO PFC 200 There is an out-of-bounds write vulnerability in the firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. WAGO PFC200 is a programmable logic controller (PLC) from German WAGO company
