Lifecycle Timeline
3DescriptionCVE.org
WatchGuard Dimension is susceptible to a denial-of-service condition when an attacker sends a high volume of TCP SYN packets to the log listening service.
AnalysisAI
WatchGuard Dimension's log listening service can be rendered unavailable by an unauthenticated remote attacker flooding it with TCP SYN packets, a classic resource exhaustion denial-of-service technique. The CVSS 4.0 base score of 8.7 reflects high availability impact with no authentication, no user interaction, and no configuration prerequisite required. …

Vulnerability AssessmentAI
| Exploitation | No special configuration, authentication, or elevated privilege is required - the attack targets the log listening service in its default operational state. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 8.7 reflects a network-accessible (AV:N), low-complexity (AC:L), no-privilege (PR:N), no-user-interaction (UI:N) attack path with high availability impact (VA:H) and no confidentiality or integrity impact - metrics that accurately characterize a SYN flood attack. … 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 | Consult the WatchGuard PSIRT advisory at https://psirt.watchguard.com/CVE-2026-13108 for patch or upgrade details; patch availability is confirmed per vendor advisory, but no specific fixed version number is independently verifiable from the available intelligence data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all WatchGuard Dimension deployments across the organization and assess network exposure of the log listening service to untrusted networks. …
