TITLE:
JAF CMS Script Insertion and PHP Code Injection

SECUNIA ADVISORY ID:
SA22143

VERIFY ADVISORY:
http://secunia.com/advisories/22143/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting, System access

WHERE:
>From remote

SOFTWARE:
JAF CMS 4.x
http://secunia.com/product/12130/

DESCRIPTION:
NanoyMaster has discovered some vulnerabilities in JAF CMS, which can
be exploited by malicious people to conduct script insertion attacks
and compromise a vulnerable system.

Input passed to the "message" parameter in jafshout.php and the
"name", "url", "title", and "about" parameters when posting in the
forum is not properly sanitised before being used. This can be
exploited to inject arbitrary HTML and script code, which is executed
in a user's browser session in context of an affected site when the
malicious user data is viewed.

This can also be exploited to inject and execute arbitrary PHP code
via the "message" parameter passed in jafshout.php.

The vulnerabilities are confirmed in version 4.0 RC1. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
NanoyMaster
