Security readout for executives and security teams
Plain-English summary
This CVE covers a security misconfiguration in several NETGEAR range extenders. A nearby attacker could affect confidentiality and integrity without authentication, but the CVSS data does not indicate availability impact. The affected condition is limited to listed models running firmware older than specified fixed versions.
Executive priority
Treat this as a moderate-priority network hygiene issue. It is not presented as internet-scale or actively exploited in the supplied sources, but outdated extenders can create avoidable exposure inside offices, branches, or home-office networks.
Technical view
CVE-2017-18746 is a NETGEAR extender security settings misconfiguration with CVSS 3.0 score 6.1. The vector is adjacent network, low complexity, no privileges, no user interaction, scope changed, and low confidentiality and integrity impact. The public bundle does not provide a CWE or deeper root-cause detail.
Likely exposure
Exposure is most likely where listed NETGEAR extenders remain deployed on firmware below the fixed versions: EX3700, EX3800, EX6000, EX6130, EX6400, EX7000, EX7300, and WN2500RPv2. The adjacent-network vector suggests risk from local or nearby network access rather than broad internet reach.
Exploitation context
The provided sources do not state active exploitation, and this CVE is not marked as CISA KEV. The CVSS vector indicates exploitation requires adjacent network access but no authentication or user interaction. No public exploit details are included in the source bundle.
Researcher notes
The public record is sparse: no CWE, no detailed misconfiguration mechanics, and no exploit evidence are provided. Validation should focus on model and firmware state against the NETGEAR fixed-version list, with any deeper analysis based on vendor firmware and advisory details.
Mitigation direction
- Inventory NETGEAR extenders and identify exact model and firmware version.
- Update affected devices to the fixed NETGEAR firmware version or later.
- Follow the NETGEAR advisory for model-specific upgrade guidance.
- Retire unsupported devices if fixed firmware is unavailable from the vendor.
Validation and detection
- Confirm whether EX3700 or EX3800 firmware is at least 1.0.0.64.
- Confirm whether EX6000 firmware is at least 1.0.0.24.
- Confirm whether EX6130 firmware is at least 1.0.0.16.
- Confirm whether EX6400 or EX7300 firmware is at least 1.0.1.60.
- Confirm whether EX7000 firmware is at least 1.0.0.50.
- Confirm whether WN2500RPv2 firmware is at least 1.0.1.46.
