TITLE

WAGO PFC 200 Out-of-bounds write vulnerabilities in firmware

Trust: 0.8

sources: JVNDB: JVNDB-2019-014919

DESCRIPTION

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). A specially crafted XML cache file written to a specific location on the device can cause a stack buffer overflow, resulting in code execution. 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 subnetmask values that are greater than 1024-len(‘/etc/config-tools/config_interfaces interface=X1 state=enabled subnet-mask=‘) in length. A subnetmask value of length 0x3d9 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
