Here it is as promised - new version. It's supporting multiple target ID-s, log format is compatible with passwordspro (easy to copy-paste).

Known problems: salts, containing colon (:), are problematic and needs to be handled manually. It's because passwordspro is using colon as separator between fields :)
Anyway - feedback is welcome ...

Code:

// IPB <= 2.3.5 sql injection exploit
// Version 1.2
// written by Janek Vind "waraxe"
// 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 passwordspro
//
// 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!

I think you need a newer version of the CURL extenstion.
You can find infos here http://curl.haxx.se/libcurl/php/

Alternative way to crack your problem is to download new php package that includes curl (every since 4.0.2) and install it.

open your php.ini file in the php directory and look in the extensions section
for a line like this
Quote:
extension=php_curl.dll


probably it's commented with a leading ;
if this is the case, uncomment it and restart the webserver.
if you have no php_curl.dll entry in the extensions section of your php.ini file, add it and restart the server.
