Linux Exploit Suggester

Binary code

Background

Many moons ago I stumbled across a broken script on an incident response job.  The Hackers uploaded numerous exploits and scripts in an attempt to compromise a Linux RedHat server.  Among these files was a broken script (that did not work) that would suggest possible exploits given the release version ‘uname -r’ of the Linux Operating System.

This gave me an idea; create my own that actually works….

As the name suggests, this is a Linux Exploit Suggester, with no frills and no fancy features; just a simple script to keep track of vulnerabilities and suggest possible exploits to use to gain ‘root‘ on a legitimate penetration test, or governing examining body 🙂

Demo Time

Actions speak louder than words, so attached is sample output for querying a 2.6.28 Kernel:

$ perl ./Linux_Exploit_Suggester.pl -k 2.6.28

Kernel local: 2.6.28
