Loading vulnerability…
CVE-2018-7750 is an improper authentication vulnerability in Paramiko's SSH server implementation. In affected versions, the transport layer processes SSH requests, including channel-open, without first verifying that user authentication has completed. A customized SSH client can omit the authentication phase and submit post-authentication requests to the server.

This repository provides a proof-of-concept (PoC) exploit for CVE-2018-7750, a remote code execution vulnerability in Paramiko SSH server versions prior to 2.4.1. The repository contains two main Python scripts: 'rce.py', which is the exploit script, and 'sample_ssh_server.py', which sets up a vulnerable SSH server for testing. The exploit works by connecting to a vulnerable Paramiko SSH server (defaulting to 127.0.0.1:2222) and sending an arbitrary command ('touch /tmp/pwn') for execution, demonstrating the ability to execute remote commands. The sample server script listens on all interfaces at port 2222 and is configured to accept public key authentication, executing any command sent via the SSH 'exec' channel. The repository is structured as a PoC for security researchers to test and demonstrate the vulnerability, not as a weaponized or production-ready exploit.
