Name of the Vulnerable Software and Affected Versions WatchGuard Dimension (affected versions not specified)
Description The web login endpoint does not enforce effective rate-limiting or account lockout by default. This allows a remote attacker to perform automated password guessing against user accounts. While an account lockout setting exists to block brute-force attempts after a defined number of failed attempts, it is not enabled by default.
Recommendations Enable the account lockout setting to block automated password guessing attempts.
