Vulnerability from variot - Updated: 2022-05-17 01:57

FX3U is a high-end PLC of Mitsubishi, and its transmission layer uses COTP protocol for communication.

A buffer overflow vulnerability exists in the COTP protocol packets that are sent to the FX3U's Ethernet port in a cyclically restructured packet. Allowing an attacker to exploit this vulnerability results in a denial of service
