ssh-audit

build status
ssh-audit is a tool for ssh server auditing.

Features

  • SSH1 and SSH2 protocol server support;
  • grab banner, recognize device or software and operating system, detect compression;
  • gather key-exchange, host-key, encryption and message authentication code algorithms;
  • output algorithm information (available since, removed/disabled, unsafe/weak/legacy, etc);
  • output algorithm recommendations (append or remove based on recognized software version);
  • output security information (related issues, assigned CVE list, etc);
  • analyze SSH version compatibility based on algorithm information;
  • historical information from OpenSSH, Dropbear SSH and libssh;
  • no dependencies, compatible with Python 2.6+, Python 3.x and PyPy;

Usage

usage: ssh-audit.py [-bnv] [-l <level>] <host[:port]>

   -1,  --ssh1             force ssh version 1 only
   -2,  --ssh2             force ssh version 2 only
   -b,  --batch            batch output
   -n,  --no-colors        disable colors
   -v,  --verbose          verbose output
   -l,  --level=<level>    minimum output level (info|warn|fail)
  • batch flag -b will output sections without header and without empty lines (implies verbose flag).
  • verbose flag -v will prefix each line with section type and algorithm name.

ChangeLog

v1.6.0 (2016-10-14)

  • implement algorithm recommendations section (based on recognized software)
  • implement full libssh support (version history, algorithms, security, etc)
  • fix SSH-1.99 banner recognition and version comparison functionality
  • do not output empty algorithms (happens for misconfigured servers)
  • make consistent output for Python 3.x versions
  • add a lot more tests (conf, banner, software, SSH1/SSH2, output, etc)
  • use Travis CI to test for multiple Python versions (2.6-3.5, pypy, pypy3)

v1.5.0 (2016-09-20)

  • create security section for related security information
  • match and output assigned CVE list and security issues for Dropbear SSH
  • implement full SSH1 support with fingerprint information
  • automatically fallback to SSH1 on protocol mismatch
  • add new options to force SSH1 or SSH2 (both allowed by default)
  • parse banner information and convert it to specific sofware and OS version
  • do not use padding in batch mode
  • several fixes (Cisco sshd, rare hangs, error handling, etc)
