Yeah,its so weird. vulnerable code in pagestart.php at line 68. http://victim/modules/Forums/admin/admin_styles.php?phpbb_root_path=2 Warning: main(2common.php): failed to open stream: No such file or directory in C:InetpubvhostsvictimhttpdocsmodulesForumsadminpagestart.php on line 68 Just edited victim for security purposes. in pagestart.php at lines 67-68: ... include("../../../mainfile.php"); include($phpbb_root_path.'common.'.$phpEx); ... So it includes mainfile.php and i think this is making vulnerability. in mainfile.php at lines 54-56 ... if (!ini_get("register_globals")) { import_request_variables('GPC'); } ... I tried it on some servers.It didnt work but for some worked, and all this servers has register_globals off and magic_quotes_gpc on. This is so weird problem..
