Fiche créée le 2007-04-07 23:18:21, dernière mise à jour le 2009-02-08 16:32:08
Advanced Guestbook contains a flaw that allows a remote attacker to execute an arbitrary php script on the target server. The issue is due to index.php not properly sanitizing user input, specifically directory traversal style attacks (../../) supplied via the 'lang' variable supplied via cookies.
This vulnerability is only present when the register_globals PHP option is set to 'on'. This has not been the default setting for PHP installs since version 4.2.0 (22-Apr-2002).
