Vulnerability from variot
An exploitable heap buffer overflow vulnerability exists in the iocheckd service "I/O-Check" functionality of WAGO PFC200 Firmware versions 03.01.07(13) and 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 The firmware contains an out-of-bounds write vulnerability for a critical function.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. WAGO PFC200 is a programmable logic controller (PLC) from the German company WAGO.
WAGO PFC200 has a buffer overflow vulnerability. 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
