Detailed vulnerability description
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to insufficient patch released in version 9.644. The name of the uploaded file is constructed from a user-supplied value passed via
$formSession variable. A remote authenticated attacker can upload an arbitrary file, change the session variable value to a string, containing directory traversal characters (e.g. "../"), bypass the implemented path traversal protection and upload arbitrary file to the system.
Successful exploitation of this vulnerability may result in website compromise.
