CVE-2021-45732: Netgear Nighthawk R6700 version 1.0.4.120 makes use of a hardcoded credential.

Netgear Nighthawk R6700 version 1.0.4.120 makes use of a hardcoded credential. It does not appear that normal users are intended to be able to manipulate configuration backups due to the fact that they are encrypted/obfuscated. By extracting the configuration using readily available public tools, a user can reconfigure settings not intended to be manipulated, repackage the configuration, and restore a backup causing these settings to be changed.

Security readout for executives and security teams

Plain-English summary

This issue affects Netgear Nighthawk R6700 firmware version 1.0.4.120. A hardcoded credential can allow router configuration backups to be decoded, changed, repackaged, and restored, altering settings that ordinary users were not expected to control.

Executive priority

Treat this as a targeted router configuration integrity risk. Prioritize if R6700 devices are internet-facing, used in business networks, or administered by multiple users. Evidence is insufficient for emergency response based only on the supplied sources.

Technical view

CVE-2021-45732 describes hardcoded credential use in R6700 1.0.4.120 related to encrypted or obfuscated configuration backups. The cited record says public tools can extract the configuration, allow unauthorized setting changes, and restore the modified backup. No CVSS, CWE, patch, or exploit status is provided.

Likely exposure

Exposure appears limited to Netgear Nighthawk R6700 devices running firmware 1.0.4.120 where configuration backups can be obtained and restored. The sources do not establish remote unauthenticated exploitation or broader Netgear model impact.

Exploitation context

The CVE is not listed as KEV, and the provided sources do not claim active exploitation. The described abuse path involves manipulating configuration backups rather than a network payload or direct compromise path.

Researcher notes

The source evidence names one firmware version and one product. It does not provide CVSS, CWE mapping, full prerequisites, fixed versions, or proof of active exploitation. Avoid extrapolating to other Netgear devices without vendor confirmation.

Mitigation direction

  • Inventory Netgear Nighthawk R6700 devices and identify firmware version 1.0.4.120.
  • Check Netgear and Tenable guidance for fixed firmware or official mitigation details.
  • Restrict router administration access to trusted administrators only.
  • Protect stored configuration backups from user or attacker access.
  • Disable or tightly control backup restoration workflows where operationally possible.

Validation and detection

  • Confirm whether any R6700 devices run firmware version 1.0.4.120.
  • Review router administration logs for unexpected configuration backup restores.
  • Inspect recent configuration changes for unauthorized or unexplained settings.
  • Verify backup files are stored in restricted locations.
  • Track vendor advisories for patch availability or affected-version clarification.
