VERIFY ADVISORY:
http://secunia.com/advisories/29429/

CRITICAL:
Moderately critical

IMPACT:
Manipulation of data, Exposure of sensitive information

WHERE:

SOFTWARE:
Acajoom PRO 1.x (component for Joomla)
http://secunia.com/product/17982/

DESCRIPTION:
fataku has reported a vulnerability in the Acajoom PRO component for
Joomla!, which can be exploited by malicious people to conduct SQL
injection attacks.

Input passed to the "mailingid" parameter in the Joomla!
installation's index.php script (when "option" is set to
"com_acajoom", "act" to "mailing", and "task" to "view") 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 reported in versions 1.2.5 and 1.1.5. Other
versions may also be affected.

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