The specific flaw exists within the web portal listening on TCP port 443, under Maintenance → File Management → File Browser, which is affected by a directory traversal vulnerability. By exploiting this vulnerability, an authenticated attacker can access and delete files outside of the intended directory, including files belonging to the Mitel application and the underlying Linux system. Deleting critical system or application files can result in a denial-of-service condition affecting the underlying system.
