Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
WatchGuard Dimension's web login endpoint permits unlimited automated password guessing against user accounts because rate-limiting and account lockout are both absent in the default product configuration. All versions of Dimension (CPE wildcard, no version boundary) are affected in default-configured deployments. …

Vulnerability AssessmentAI
| Exploitation | The primary enabling condition is WatchGuard Dimension's default configuration: account lockout is disabled out of the box, so any deployment that has not explicitly enabled this setting accepts unlimited authentication attempts. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 6.3 with vector AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N reflects a network-exposed, unauthenticated attack path with moderate complexity. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary mitigation is to immediately enable the account lockout setting within WatchGuard Dimension's administrative configuration, which blocks further authentication attempts after a defined number of consecutive failures; administrators should set a low threshold (5-10 attempts) and a meaningful lockout duration. … Detailed patch versions, workarounds, and compensating controls in full report. |
