VAR-201608-0414
Vulnerability from variot - Updated: 2022-05-17 02:03Mitsubishi L06 is a high-end PLC of Mitsubishi. Its Ethernet communication module LJ71E71-100-CM opens web services and supports http protocol communication. You can access and set device configuration information by logging in to the web server.
In the HTTP message sent to the LJ71E71-100-CM, if it is a Connect type request, injecting a long string after the Connect field can trigger a buffer overflow of the communication module and there is a security vulnerability. Allowing an attacker to exploit this vulnerability results in a denial of service
