Security readout for executives and security teams
Plain-English summary
Some NETGEAR routers and the D6100 modem/router contain a command injection flaw. If successfully exploited, it could let an attacker run unintended commands on the device, risking confidentiality, integrity, and availability. The source bundle does not show active exploitation.
Executive priority
Treat this as high priority for environments still using the affected NETGEAR devices. The business risk is device compromise and service disruption, but current sources do not establish active exploitation.
Technical view
CVE-2017-18794 is a command injection vulnerability in specified NETGEAR firmware. It has CVSS 3.0 score 8.4 with local attack vector, low complexity, no privileges, no user interaction, unchanged scope, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to listed NETGEAR models running firmware older than the named fixed thresholds: R6300v2, R6400, R6700, R7000, R7100LG, R7900, R8000, R8500, and D6100.
Exploitation context
The bundle marks KEV as false and provides no cited evidence of active exploitation. CVSS indicates local attack vector, so vulnerability managers should not assume internet-reachable exploitation from these sources alone.
Researcher notes
The source data is sparse: no CWE, no exploit details, and no named vulnerable component beyond command injection. Avoid expanding affected scope beyond the listed models and firmware thresholds.
Mitigation direction
- Identify deployed NETGEAR models and firmware versions.
- Upgrade affected devices to the listed fixed firmware versions or later.
- Prioritize devices in sensitive networks or supporting critical connectivity.
- Check NETGEAR advisory for model-specific upgrade guidance.
- Retire unsupported or unpatchable affected devices.
Validation and detection
- Inventory NETGEAR R6300v2, R6400, R6700, R7000, R7100LG, R7900, R8000, R8500, and D6100 devices.
- Compare firmware versions against the affected version thresholds in the CVE description.
- Confirm upgraded devices report fixed firmware or later.
- Review asset records for unmanaged consumer routers in business networks.
- Document exceptions where devices cannot be updated.
