CVE-2026-71948Network attack vector

Unauthenticated root command execution via diagnostic host injection

Published Aug 8, 2026 · Updated Aug 8, 2026

Command injection in D-Link DWR-M961 C1 firmware before 1.1.5_C1_202607071108 allows remote attackers to execute commands as root. The /boafrm/formDebugDiagnosticRun web-management CGI incorporates the attacker-controlled host field into an OS command without adequate neutralization. No authentication or user interaction is required; a network request to the management interface grants root-level command execution on the device.
