Tripp Lite PDUMH15AT 12.04.0053 and SU750XL 12.04.0052 devices allow unauthenticated POST requests to the /Forms/ directory, as demonstrated by changing the manager or admin password, or shutting off power to an outlet. NOTE: the vendor's position is that a newer firmware version, fixing this vulnerability, had already been released before this vulnerability report about 12.04.0053.
