Security readout for executives and security teams
Plain-English summary
A remote attacker could take complete control of an affected D-Link DWR-M961 router without credentials or user interaction. Successful exploitation executes commands as root, potentially exposing traffic, changing router settings, disrupting connectivity, or enabling further compromise.
Executive priority
Treat confirmed affected, externally reachable devices as an immediate remediation priority. Root-level compromise could undermine network confidentiality and availability. Internal-only devices remain urgent because any attacker with network access may require neither credentials nor user interaction.
Technical view
CVE-2026-71955 is a CWE-78 command-injection flaw in /boafrm/formWsc. Unsanitized values in localPin, targetAPSsid, peerPin, and peerRptPin can reach command execution with root privileges. The CVSS 3.1 score is 9.8, reflecting network access, low complexity, no privileges, no interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
The description identifies DWR-M961 hardware revision C1 running software 1.1.2_C1_202602110044. Risk is greatest where the vulnerable interface is reachable from untrusted networks. The structured affected-version entry says “0,” so asset owners should reconcile inventory against the vendor advisory.
Exploitation context
The supplied sources support remote, unauthenticated root command execution. The CVE is not listed as KEV, and the bundle provides no evidence of active exploitation. Absence from KEV does not establish that exploitation is impossible or nonexistent.
Researcher notes
The affected scope is internally inconsistent: the narrative names hardware C1 and software 1.1.2_C1_202602110044, while the structured record lists version “0.” Validate scope with D-Link. The bundle names a vendor advisory as a patch reference but does not state the fixed version or mitigation details.
Mitigation direction
- Check D-Link advisory SAP10512 for the applicable firmware update or vendor-directed remediation.
- Prioritize affected routers whose management interfaces are reachable from untrusted networks.
- Restrict management access to trusted administrative networks while remediation is pending.
- Replace or isolate devices if vendor-supported remediation is unavailable.
Validation and detection
- Inventory DWR-M961 devices and record their hardware revision and exact software version.
- Determine whether /boafrm/formWsc is reachable from untrusted or external networks.
- Review device and perimeter logs for unexpected requests to /boafrm/formWsc.
- Check for unexplained configuration changes, restarts, accounts, or outbound connections.
- Confirm remediation status against D-Link advisory SAP10512.

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
