Description

This module detect and exploits CVE-2025-32433, a pre-authentication vulnerability in Erlang-based SSH servers that allows remote command execution. By sending crafted SSH packets, it executes a payload to establish a reverse shell on the target system. The exploit leverages a flaw in the SSH protocol handling to execute commands via the Erlang `os:cmd` function without requiring authentication.

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.
