Security readout for executives and security teams
Plain-English summary
Some NETGEAR router and gateway firmware versions are vulnerable to cross-site request forgery. If an administrator is tricked into interacting with malicious web content while authenticated to the device, settings could be changed with serious confidentiality and integrity impact.
Executive priority
Prioritize remediation for internet-adjacent or business-critical locations using these models. The issue is high severity, but the provided evidence does not show known active exploitation.
Technical view
CVE-2017-18775 is a CSRF issue affecting listed NETGEAR models before specific firmware versions. The CVSS 3.0 score is 8.8 with network attack vector, low complexity, no privileges required, user interaction required, and high confidentiality and integrity impact.
Likely exposure
Exposure is most likely where affected NETGEAR R6100, R7500, WNDR3700v4, WNDR4300v1/v2, WNDR4500v3, or WNR2000v5 devices run firmware below the listed fixed versions.
Exploitation context
The provided bundle does not show CISA KEV listing or active exploitation evidence. The CVSS vector indicates user interaction is required, consistent with a CSRF scenario involving an authenticated administrative browser session.
Researcher notes
The source bundle lacks CWE detail, exploit maturity, and advisory body text. Analysis is limited to the CVE description, CVSS vector, affected model/version list, KEV=false status, and NETGEAR advisory reference.
Mitigation direction
- Identify listed NETGEAR models and record current firmware versions.
- Upgrade affected devices to the fixed firmware version or later listed for that model.
- Review NETGEAR advisory guidance before applying operational workarounds.
- Restrict router administration to trusted networks where supported.
- Replace unsupported devices if fixed firmware is unavailable.
Validation and detection
- Compare each device model and firmware against the affected version list.
- Confirm updated firmware is at or above the model-specific fixed version.
- Check whether administrative interfaces are reachable only from approved networks.
- Document any device that cannot be updated and track compensating controls.
