Low risk25th percentile - higher than 25% of all known CVEs
Summary
WatchGuard Dimension's web login endpoint does not enforce effective rate-limiting or account lockout by default, allowing a remote attacker to perform automated password guessing against user accounts. If the account lockout setting is enabled, brute-force attempts are blocked after a defined number of failed attempts, but this setting is not enabled by default.
Risk Assessment
The risk is the possibility of brute-force attacks on user accounts, which could lead to unauthorized access to the system. The lack of default account lockout increases susceptibility to dictionary attacks and password guessing.
Recommendation
It is recommended to enable the account lockout setting in WatchGuard Dimension and configure rate limiting for the login endpoint. Also, enforce strong passwords and consider implementing multi-factor authentication.
