vulners-scanner

Description

PoC of a host-based vulnerability scanner, which uses vulners.com API. Detects operating system, collects installed packages and checks vulnerabilities in it.

Supported OS

Currently support collecting packages for these operating systems:

  • Debian-based (debian, kali, ubuntu)
  • Rhel-based (redhat, centos, fedora)

Python version

Lazy and Advanced versions were tested on a python2.6, python2.7, python3.5. If you found any bugs, don't hesitate to open issue

Docker support

Experimental support of detecting vulnerabilities in running docker containers (only advanced script). Need to activate it changing checkDocker=False to checkDocker=True in linuxScanner.py

How to use

  • Lazy scanner The simplest script to show vulners.com API capabilities. Just run script and it will return all found vulnerabilities:
# git clone https://github.com/videns/vulners-scanner
# cd vulners-scanner
# ./lazyScanner.py
OS Name - debian, OS Version - 8
