VAR-202001-0422
Vulnerability from variot - Updated: 2023-12-18 12:27An exploitable heap 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 heap buffer overflow, potentially resulting in code execution. An attacker can send unauthenticated packets to trigger this vulnerability. WAGO PFC 200 and PFC100 Firmware contains an out-of-bounds write vulnerability.Information is acquired, information is falsified, and denial of service (DoS) May be in a state. WAGO PFC 200 and WAGO PFC100 are both programmable logic controllers (PLCs) from the German company WAGO.
There is a buffer overflow vulnerability in the 'I / O-Check' function in WAGO PFC200 and PFC100. 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
