CVE‑2016‑1555: NETGEAR Wireless Access Point Command‑Injection Vulnerability Allows Unauthenticated Code Execution
What It Is – A command‑injection flaw in the web management interface of several NETGEAR Wireless Access Point (WAP) models. An attacker can supply crafted form data that is passed directly to the device’s CLI, enabling arbitrary code execution without authentication.
Exploitability – The vulnerability is publicly disclosed, has a CVSS v3.1 base score of 7.5 (High), and proof‑of‑concept exploits are available. No patch was released until after the CISA KEV listing.
Affected Products – NETGEAR WAP series including models WAC104, WAC124, WAC124v2, WAC124v3, WAC124v4, WAC124v5, WAC124v6, WAC124v7, WAC124v8, WAC124v9, WAC124v10, and similar devices that expose the vulnerable web UI.
Why It Matters for Trust & Control Assurance
- Demonstrates the need for continuous vulnerability management – evidence that assets are inventoried, scanned, and patched in a timely manner satisfies a single VCF control that maps to many frameworks (e.g., NIST CSF 2.0 “Detect” function).
- Unauthenticated command injection bypasses network segmentation controls, highlighting gaps in secure configuration and the importance of documented hardening baselines.
- A breach stemming from this flaw would erode the audit trail that enterprises rely on to prove due‑diligence to regulators and partners.
Recommended Actions
- Inventory all NETGEAR WAP devices and verify firmware versions against the vendor’s advisory.
- Apply the latest firmware patches released by NETGEAR or, if unavailable, isolate the devices on a segmented VLAN and restrict web UI access to trusted management workstations.
- Update your vulnerability management program to include regular scans for legacy network hardware and retain remediation evidence in a centralized Trust Center.
- Document the remediation steps and retain logs as proof of control execution for future audits.
