TITLE:
PHP-Nuke "modules/Search/index.php" SQL Injection

SECUNIA ADVISORY ID:
SA28624

VERIFY ADVISORY:
http://secunia.com/advisories/28624/

CRITICAL:
Moderately critical

IMPACT:
Manipulation of data, Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
PHP-Nuke 8.x
http://secunia.com/product/13524/

DESCRIPTION:
Foster & 1dt.w0lf have discovered a vulnerability in PHP-Nuke, which
can be exploited by malicious people to conduct SQL injection
attacks.

Input passed to the "sid" parameter through modules.php to
modules/Search/index.php (when "type" is set to "comments") is not
properly sanitised before being used in SQL queries. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation allows e.g. retrieving the administrator
password hash, but requires that "magic_quotes_gpc" is disabled - not
the value recommended by the installer - and having knowledge of the
database table prefix.

The vulnerability is confirmed in version 8.0. Other versions may
also be affected.

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

Set "magic_quotes_gpc" in php.ini to On.

Use another product.
