VAR-201912-0773
Vulnerability from variot - Updated: 2023-12-18 12:27An exploitable stack buffer overflow vulnerability exists in the iocheckd service ''I/O-Check'' functionality of WAGO PFC200 Firmware version 03.01.07(13), WAGO PFC200 Firmware version 03.00.39(12) and WAGO PFC100 Firmware version 03.00.39(12). A specially crafted set of packets can cause a stack buffer overflow, resulting in code execution. An attacker can send unauthenticated packets to trigger this vulnerability. WAGO PFC 200 and PFC100 The firmware contains a classic buffer overflow vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. WAGO PFC 200 is a programmable logic controller (PLC) from the German company WAGO.
A buffer overflow vulnerability exists in the I / O-Check function in WAGO PFC 200. The vulnerability originates from a network system or product that incorrectly validates data boundaries when performing operations on memory, causing incorrect read and write operations to be performed on other associated memory locations. An attacker could use this vulnerability to cause a buffer overflow or heap overflow
