AnalysisAIv1 – Sep 15, 2026

Unauthenticated attackers positioned on an adjacent network segment can gain root-level control of Digital Watchdog VMAX A1 PLUS, VMAX A1 G4, VA1G4 and VG4 recorders and VMAX IP G4 NVRs, because a critical function performs no authentication and forwards received bytes straight into a system command. CWE-306 combined with that unsafe command handling gives full loss of confidentiality, integrity and availability on the device and on any footage, stored credentials or downstream network reachable through it. Neither public exploit code nor a CISA KEV entry appears in the supplied intelligence, so active exploitation is not confirmed, but the CVSS 4.0 base score of 8.7 reflects the near-trivial effort once adjacency is achieved.

DescriptionCVE.org

The affected products are missing authentication for a critical function, which could allow an attacker to run as root and pass received bytes directly to a system command.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
