CRITICAL:
Moderately critical

IMPACT:
Manipulation of data, Exposure of sensitive information

WHERE:

SOFTWARE:
NeoReferences 1.x (component for Joomla)

DESCRIPTION:
S@BUN has discovered a vulnerability in the NeoReferences component
for Joomla, which can be exploited by malicious people to conduct SQL
injection attacks.

Input passed to the "catid" parameter in the Joomla installation's
index.php script (when "option" is set to "com_neoreferences") 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 administrator
usernames and password hashes, but requires knowledge of the database
table prefix.

The vulnerability is confirmed in version 1.3.3 and reported in
version 1.3.1. Other versions may also be affected.

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