CVE-2017-18766: Certain NETGEAR devices are affected by an attacker's ability to read arbitrary files.

Certain NETGEAR devices are affected by an attacker's ability to read arbitrary files. This affects DST6501 before 1.1.0.6 and WNR2000v2 before 1.2.0.8.

Security readout for executives and security teams

Plain-English summary

Some NETGEAR DST6501 and WNR2000v2 devices can allow an unauthenticated nearby network attacker to read files from the device. For an organization still using these legacy models, this could expose sensitive router configuration or other device data and should be prioritized for inventory and firmware remediation.

Executive priority

Treat this as high priority if either affected NETGEAR model remains in use. The business decision is straightforward: confirm inventory, update firmware where supported, and replace unsupported devices rather than accepting exposure on legacy network infrastructure.

Technical view

CVE-2017-18766 is an arbitrary file read issue affecting NETGEAR DST6501 before 1.1.0.6 and WNR2000v2 before 1.2.0.8. The CVSS 3.0 score is 8.8 with adjacent-network access, low complexity, no privileges, and no user interaction required.

Likely exposure

Exposure appears limited to NETGEAR DST6501 and WNR2000v2 devices running firmware below the versions named in the CVE source bundle. The CVSS vector indicates adjacent-network reachability, so internal, Wi-Fi, guest, or bridged network access is the likely concern.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. Risk remains meaningful because the vulnerability is unauthenticated, low-complexity, and could expose files from network devices that often hold sensitive configuration data.

Researcher notes

The source bundle is sparse: no CWE is listed, and affected CPE data is not populated. Analysis should stay tied to the named NETGEAR models and firmware thresholds. The CVSS vector supports adjacent-network, unauthenticated validation focus, not internet-wide assumptions.

Mitigation direction

  • Upgrade DST6501 firmware to 1.1.0.6 or later if available from NETGEAR.
  • Upgrade WNR2000v2 firmware to 1.2.0.8 or later if available from NETGEAR.
  • Check NETGEAR’s advisory for model-specific guidance and support status.
  • Restrict management and device access to trusted networks only.
  • Retire affected devices if supported firmware is unavailable.

Validation and detection

  • Inventory environments for NETGEAR DST6501 and WNR2000v2 devices.
  • Confirm firmware versions against the affected thresholds in the CVE record.
  • Verify affected devices are not reachable from guest or untrusted networks.
  • Review router configuration exposure and administrative access controls.
  • Document remediation status for every identified device.
