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, RBK842 before 3.2.15.25, RBR840 before 3.2.15.25, RBS840 before 3.2.15.25, RBK852 before 3.2.15.25, RBK853 before 3.2.15.25, RBR850 before 3.2.15.25, and RBS850 before 3.2.15.25.

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

Multiple NETGEAR Orbi mesh WiFi systems (RBK752, RBK753, RBK753S, RBR750, RBS750, RBK842, RBR840, RBS840, RBK852, RBK853, RBR850, RBS850) contain a vulnerability allowing disclosure of administrative credentials. An unauthenticated or authenticated attacker could exploit this to gain full administrative access to affected devices.

MitigationUpdate the firmware on affected NETGEAR Orbi devices to version 3.2.15.25 or later to remediate the credential disclosure vulnerability. After updating, change all administrative credentials as a precaution.

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 your Orbi device model
    Log into the Orbi web interface (typically at 192.168.1.1) or use the Orbi mobile app. Navigate to Settings > About or Administration > Router Status to view the model number (e.g., RBK752, RBR750, etc.).
    Affected if Your model is one of: RBK752, RBK753, RBR750, RBS750, RBK842, RBR840, RBS840 (or related variants like RBK753S) and the firmware version is below 3.2.15.25.
  2. Check the installed firmware version
    In the Orbi web interface, go to Administration > Router/Firmware Update or Settings > About. The current firmware version is displayed (format: x.x.x.x). Note that Satellites will show their own firmware version separately.
    Affected if The displayed firmware version is lower than 3.2.15.25.
  3. Verify both router and satellite firmware versions
    If using a mesh system, check the firmware version for each satellite unit. In the web interface, look for a connected devices list or satellite status page. Each satellite must also be running firmware 3.2.15.25 or later.
    Affected if Any device in the mesh system (router or satellite) is running firmware below 3.2.15.25.

You are affected if your Orbi router or any satellite is running firmware version lower than 3.2.15.25 on a vulnerable model (RBK752, RBK753, RBK753S, RBR750, RBS750, RBK842, RBR840, RBS840 or related variants).
