CVE-2026-71947: D-Link DWR-M961 Command Injection via /boafrm/formTracerouteDiagnosticRun

D-Link DWR-M961 devices with hardware version C1 and firmware version before 1.1.5_C1_202607071108 contain a command injection vulnerability in the /boafrm/formTracerouteDiagnosticRun interface. A remote attacker can inject arbitrary malicious commands into the host and ipVer fields, resulting in command execution with root privileges.

Security readout for executives and security teams

Plain-English summary

A critical flaw in D-Link DWR-M961 routers can let a remote, unauthenticated attacker run operating-system commands as root. Successful exploitation could expose traffic or credentials, alter router settings, disrupt connectivity, or enable persistent compromise. The stated scope is hardware revision C1 running firmware older than 1.1.5_C1_202607071108.

Executive priority

Prioritize immediate identification and remediation of affected routers, especially those reachable from untrusted networks. Root-level compromise of an edge device can threaten both connectivity and downstream systems. Escalate any exposed or suspicious device for incident investigation rather than treating firmware installation alone as proof it was never compromised.

Technical view

CVE-2026-71947 is CWE-78 command injection in /boafrm/formTracerouteDiagnosticRun. Unsanitized host and ipVer values can reach command execution with root privileges. Its CVSS 3.1 score is 9.8: network-accessible, low complexity, no privileges or user interaction, with high confidentiality, integrity, and availability impact.

Likely exposure

Exposure exists where a DWR-M961 C1 running affected firmware permits network access to the vulnerable diagnostic interface. The sources do not establish whether every device exposes it from the internet by default. Internet-reachable administration or diagnostic interfaces would materially increase urgency.

Exploitation context

The supplied record does not identify this CVE as CISA KEV-listed and provides no evidence of active exploitation. The vulnerability nevertheless presents high inherent risk because exploitation is described as remote, unauthenticated, low-complexity root command execution. Treat exploit prevalence as unknown, not absent.

Researcher notes

The affected parameters are host and ipVer within /boafrm/formTracerouteDiagnosticRun. Reported execution context is root. The bundle limits the affected scope to DWR-M961 hardware C1 before firmware 1.1.5_C1_202607071108. Authentication-path details, default WAN exposure, indicators of compromise, and observed exploitation are not established by the supplied evidence.

Mitigation direction

  • Upgrade DWR-M961 C1 devices to firmware 1.1.5_C1_202607071108 or later using D-Link guidance.
  • Restrict management and diagnostic interfaces to trusted administrative networks.
  • Prevent direct internet access to the router administration interface.
  • Preserve relevant logs and investigate potentially exposed devices for compromise.
  • Replace devices that cannot receive or safely run the vendor-supported firmware.

Validation and detection

  • Inventory DWR-M961 devices and confirm each unit's hardware revision.
  • Record installed firmware and identify versions older than 1.1.5_C1_202607071108.
  • Verify the diagnostic and administration interfaces are unreachable from untrusted networks.
  • Confirm the approved firmware update completed and persisted after reboot.
  • Review available logs for unexpected requests to /boafrm/formTracerouteDiagnosticRun.
  • Investigate unexpected configuration changes, processes, accounts, or outbound connections.
