  5. // IPB 3.0.1 sql injection exploit
  6. // Version 1.0
  7. // written by Cryptovirus
  8. // http://de.crypt.in/
  9. // 31. january 2010
  10. //
  11. // FEATURES:
  12. // 1. Fetching algorithm optimized for speed
  13. // 2. Attack goes through $_POST, so no suspicious logs
  14. // 3. Pretesting saves time if IPB is not vulnerable
  15. // 4. curl extension autoloading
  16. // 5. log format compatible with passwordspro
  17. //
  18. // NB! This exploit is meant to be run as php CLI!
