Critical
Reference: CVE-2016-9836
NVD Link: https://nvd.nist.gov/vuln/detail/CVE-2016-9836
Title: Joomla Improper Access Control Vulnerability
Overview:

The file scanning mechanism of JFilterInput::isFileSafe() in Joomla CMS before 3.6.5 does not consider alternative PHP file extensions when checking uploaded files for PHP content which enables a user to upload and execute files with the .php6 .php7 .phtml and .phpt extensions. Additionally JHelperMedia::canUpload() did not blacklist these file extensions as uploadable file types.
