Snap One OvrC Pro versions prior to 7.2 have their own locally running web server accessible both from the local network and remotely. OvrC cloud contains a hidden superuser account accessible through hard-coded credentials.
Weakness
The product uses weak credentials (such as a default key or hard-coded password) that can be calculated, derived, reused, or guessed by an attacker.

Extended Description
By design, authentication protocols try to ensure that attackers must perform brute force attacks if they do not know the credentials such as a key or password. However, when these credentials are easily predictable or even fixed (as with default or hard-coded passwords and keys), then the attacker can defeat the mechanism without relying on brute force. Credentials may be weak for different reasons, such as:
Even if a new, unique credential is intended to be generated for each product installation, if the generation is predictable, then that may also simplify guessing attacks.
