Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Certain NETGEAR devices are affected by disclosure of administrative credentials. This affects RBK752 before 3.2.15.25, RBK753 before 3.2.15.25, RBK753S before 3.2.15.25, RBR750 before 3.2.15.25, RBS750 before 3.2.15.25, RBK852 before 3.2.10.11, RBK853 before 3.2.10.11, RBR850 before 3.2.10.11, RBS850 before 3.2.10.11, RBK842 before 3.2.10.11, RBR840 before 3.2.10.11, and RBS840 before 3.2.10.11.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This vulnerability allows disclosure of administrative credentials on affected NETGEAR Orbi mesh WiFi systems (RBK752, RBK753, RBK753S, RBR750, RBS750, RBK852, RBK853, RBR850, RBS850, RBK842, RBR840, RBS840). An unauthenticated or authenticated attacker could obtain administrative credentials, enabling full administrative access to the device and network.

MitigationUpdate firmware to version 3.2.15.25 or later for RBK752/753/753S/RBR750/RBS750 models, and version 3.2.10.11 or later for RBK852/853/RBR850/RBS850/RBK842/RBR840/RBS840 models.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Orbi model number
    Check the product label on the device bottom or access the web admin interface at orbilogin.com or 192.168.1.1 and look for the model name displayed on the dashboard or in the router settings.
    Affected if The model is one of: RBK752, RBK753, RBK753S, RBR750, RBS750, RBK852, RBK853, RBR850, RBS850, RBK842, RBR840, or RBS840.
  2. Check the current firmware version
    In the Orbi web interface, navigate to Settings > Advanced > Router Update or look for a Firmware Version field on the main dashboard. Alternatively, open the NETGEAR Orbi app and select the router to view firmware information.
    Affected if A firmware version is displayed that can be compared to the affected ranges.
  3. Compare version for RBK752/753/753S/RBR750/RBS750 models
    If your model is RBK752, RBK753, RBK753S, RBR750, or RBS750, compare your installed firmware version number against 3.2.15.25.
    Affected if The installed version is lower than 3.2.15.25 (for example, 3.2.14.XX or earlier).
  4. Compare version for RBK852/853/RBR850/RBS850 models
    If your model is RBK852, RBK853, RBR850, or RBS850, compare your installed firmware version number against 3.2.10.11.
    Affected if The installed version is lower than 3.2.10.11 (for example, 3.2.9.XX or earlier).
  5. Note RBK842/RBR840/RBS840 model status
    These models are listed as affected but specific version thresholds were not provided in the advisory. Treat any firmware version as potentially vulnerable unless NETGEAR has published a fixed version for these models.
    Affected if The device is an RBK842, RBR840, or RBS840 running any firmware version below what NETGEAR has released as a fix.

The environment is affected if the Orbi model matches the listed products and the installed firmware version falls below the threshold for its model family (3.2.15.25 for RBK752/753/753S/RBR750/RBS750, or 3.2.10.11 for RBK852/853/RBR850/RBS850).
