CVE-2018-15473 - SSH Username Enumeration Exploit

A tool for enumerating valid usernames on vulnerable SSH servers (OpenSSH 2.3 through 7.7).

📋 Vulnerability Description

CVE-2018-15473 allows enumeration of existing users on SSH servers by sending malformed authentication packets. The server responds differently to malformed packets depending on whether the user exists:

  • If user DOES NOT exist → Server immediately returns SSH2_MSG_USERAUTH_FAILURE
  • If user EXISTS → Server attempts to parse the packet, encounters an error, and closes the connection without any response

This tool sends specially crafted packets and interprets the server's response to determine which usernames are valid.

⚙️ Requirements

  • Python 3.6 or newer
  • paramiko library

Install Dependencies

root@kitploit:~
pip3 install paramiko
