Description

This module abuses a buffer overflow vulnerability to trigger a Denial of Service of the BKCLogSvr component in the Yokogaca CENTUM CS 3000 product. The vulnerability exists in the handling of malformed log packets, with an unexpected long level field. The root cause of the vulnerability is a combination of usage of uninitialized memory from the stack and a dangerous string copy. This module has been tested successfully on Yokogawa CENTUM CS 3000 R3.08.50.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
