CVE-2026-71948 D-Link CVE debrief

CVE-2026-71948 is a critical command injection vulnerability in D-Link DWR-M961 devices with hardware version C1 and firmware version before 1.1.5_C1_202607071108. The vulnerability exists in the /boafrm/formDebugDiagnosticRun interface, allowing remote attackers to inject arbitrary malicious commands into the host field, resulting in command execution with root privileges. This vulnerability has a CVSS score of 9.3, indicating critical severity. Affected product deployments should be identified in managed environments, and owners should be assigned for follow-up. Official advisories or CVE records should be reviewed to validate affected scope, severity, and vendor guidance. Vendor-supported updates or mitigations should be planned through normal change control where exposure is confirmed. Compensating controls for exposed systems should be reviewed while remediation is scheduled and verified. Relevant monitoring, detection, and logs should be checked for exposed assets that need extra review. Exceptions should be tracked, and remediated assets should be retested, with the item only closed after evidence is documented.
