I manage to get a shell on this website. It's from 2006 but has a grsec patch.

The uname -a:

Code

Linux xxxxxx 2.4.33.3-grsec #2 SMP Thu Sep 14 21:34:19 EDT 2006 i686

Since it's grsec, is it rootable?

Well, technically, yes.
It's still gonna be hell, though, unless you use a userland non-memory-corruption-based exploit.

Jon Oberheide and Dan Rosenberg did a great paper on a technique they call "stackjacking" that can get you root on quite a few grsecurity kernels.

Good luck, you're gonna need it, and may the source be with you.
