Synopsis

Joomla! 3.x < 3.9.27 Multiple Vulnerabilities

Description

According to its self-reported version, the instance of Joomla! running on the remote web server is 3.x prior to 3.9.27. It is, therefore, affected by multiple vulnerabilities.

 - HTML was missing in the executable block list of MediaHelper::canUpload, leading to XSS attack vectors. (CVE-2021-26032)

 - A missing token check causes a CSRF vulnerability in the AJAX reordering endpoint. (CVE-2021-26033)

 - A missing token check causes a CSRF vulnerability in data download endpoints in com_banners and com_sysinfo. (CVE-2021-26034)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to Joomla! version 3.9.27 or latest.
