A cross-site scripting (XSS) vulnerability was discovered in the Administrator panel on the 'Setting News' module on CMS Made Simple 2.2.14 which allows an attacker to execute arbitrary web scripts.
CMS Made Simple 2.2.14 allows an authenticated user with access to the Content Manager to edit content and put persistent XSS payload in the affected text fields. The user can get cookies from every authenticated user who visits the website.
CMS Made Simple 2.2.14 allows Authenticated Arbitrary File Upload because the File Manager does not block .ptar files, a related issue to CVE-2017-16798.
The Filemanager in CMS Made Simple 2.2.13 allows remote code execution via a .php.jpegd JPEG file, as demonstrated by m1_files[] to admin/moduleinterface.php. The file should be sent as application/octet-stream and contain PHP code (it need not be a valid JPEG file).
