WatchGuard Dimension Web UI Authentication Brute-Force Due to Missing Rate Limiting
Source: CVE Program / CVE List V5
Vulnerability Description
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.
