TITLE:
Benja CMS Cross-Site Scripting and Security Bypass Vulnerabilities

SECUNIA ADVISORY ID:
SA30834

VERIFY ADVISORY:
http://secunia.com/advisories/30834/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Benja CMS 0.x
http://secunia.com/product/19160/

DESCRIPTION:
CWH Underground has discovered some vulnerabilities in Benja CMS,
which can be exploited by malicious people to conduct cross-site
scripting attacks and bypass certain security restrictions.

1) The application does not properly restrict access to files in the
admin/ folder. This can be exploited to manipulate the site and e.g.
upload and execute arbitrary PHP code by accessing the scripts within
the /admin/ folder directly (e.g. admin/upload.php).

2) Input passed via the URL to admin/admin_edit_submenu.php,
admin/admin_new_submenu.php, and admin/admin_edit_topmenu.php is not
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in an
administrator's browser session in context of an affected site.

The vulnerabilities are confirmed in version 0.1. Other versions may
also be affected.

SOLUTION:
Restrict access to the admin/ folder (e.g. via ".htaccess"). Edit the
source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
