Remote Code Execution in D-Link DIR‑645 Router (CVE‑2015‑2051) Threatens Home and Enterprise Networks
What It Is – A remote code execution (RCE) flaw in the D‑Link DIR‑645 wired/wireless router allows an attacker to run arbitrary system commands by sending a crafted GetDeviceSettings request to the router’s HNAP interface.
Exploitability – Publicly disclosed; proof‑of‑concept code is available. CVSS v3.0 base score 7.5 (High). No authentication is required.
Affected Products – D‑Link DIR‑645 router (all firmware versions prior to the security patch released by D‑Link).
Why It Matters for Trust & Control Assurance
- Continuous asset inventory and patch‑management controls must be evidenced to prove that known vulnerabilities are remediated.
- Demonstrable audit trails of firmware updates provide the defensible evidence regulators and enterprise buyers demand.
- Mapping this vulnerability to a control objective (e.g., “Maintain up‑to‑date system components”) satisfies multiple frameworks simultaneously, reinforcing a unified trust posture.
Recommended Actions
- Deploy the latest D‑Link firmware that addresses CVE‑2015‑2051 on every DIR‑645 device.
- If the HNAP interface is not required, disable it to reduce the attack surface.
- Update your asset inventory to flag DIR‑645 routers and verify patch status on a regular cadence.
- Record remediation steps in your control‑evidence repository to support audit readiness.
