CRITICAL:
Moderately critical

IMPACT:
Manipulation of data, Exposure of sensitive information

WHERE:

SOFTWARE:
PHP-Nuke 7.x

DESCRIPTION:
Paisterist has discovered a vulnerability in PHP-Nuke, which can be
exploited by malicious people to conduct SQL injection attacks.

Input passed to the "cat" parameter through index.php to
blocks/block-Old_Articles.php 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 e.g. allows retrieval of administrator
usernames and password hashes, but requires that "register_globals"
is enabled, "magic_quotes_gpc" is disabled, and the attacker knows
the prefix for the database tables.

The vulnerability is confirmed in version 7.9. Other versions may
also be affected.

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

Use another product.
