Sysax 5.53 SSH Username Buffer Overflow

Disclosed

Description

This module exploits a vulnerability found in Sysax's SSH service. By supplying a long username, the SSH server will copy that data on the stack without proper bounds checking, therefore allowing remote code execution under the context of the user. Please note that previous versions (before 5.53) are also affected by this bug.

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.
