Linux Exploit Suggester
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:

Again, here is similar output for a more modern 3.0.0 Kernel:

Downside
Unfortunately; in all honesty it can not take into account patches or back ported patches. So may yield false positives.
