TITLE:
PHP-Nuke Personal Menu Script Insertion and SQL Injection

SECUNIA ADVISORY ID:
SA18972

VERIFY ADVISORY:
http://secunia.com/advisories/18972/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
From remote

SOFTWARE:
PHP-Nuke 7.x
http://secunia.com/product/2385/

DESCRIPTION:
Jason Lau has discovered two vulnerabilities in PHP-Nuke, which can
be exploited by malicious people to conduct SQL injection and script
insertion attacks.

1) Input passed to the "ublock" parameter in the "Your_Home"
functionality of the "Your_Account" module isn't properly sanitised
before being saved as the user's personal menu. This can be exploited
to execute arbitrary HTML and script code in a user's browser session
in context of an affected site when the user views his personal
menu.

Example:
<img src=javascript:[code]>
(requires the Microsoft Internet Explorer browser)

2) Input passed to the "user_id" parameter in the "Your_Home"
functionality of the "Your_Account" module isn't properly sanitised
before being used in a SQL query. This can be exploited to manipulate
SQL queries by injecting arbitrary SQL code. This can be further
exploited with vulnerability #1 to inject arbitrary HTML and script
code into arbitrary user's personal menu.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerabilities have been confirmed in version 7.8. Other
versions may also be affected.

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