Joomla officials have announced a new release Joomla! 3.4.5 is now available. Joomla core packages 3.2 to 3.4.4 are vulnerable to a critical vulnerability – SQL injection. The newly released Joomla version fixes the SQL injection vulnerability.
The vulnerability doesn’t require any extensions for exploitation as it is directly spotted in the core package of the Joomla. This is a most critical bug which allows unauthenticated and remote exploitation. The SQL injection vulnerable file is located at /administrator/components/com_contenthistory/models/history.php (option=com_contenthistory&view=history). The vulnerable code resides into the getListQuery() protected function.
We recommend to all users to update to latest version and harden the Joomla setup / Joomla installed on your server. If you are a hosting provider and installed Softaculous, from the cPanel you can directly upgrade Joomla installation.
