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.

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 router models suffer from a Cross-Site Request Forgery (CSRF) vulnerability in their web management interface. An attacker can trick an authenticated user into submitting malicious requests to the router's admin panel, allowing unauthorized configuration changes or device compromise. The CVSS 8.8 score reflects the high exploitability and potential impact on confidentiality, integrity, and availability.

MitigationUpdate affected NETGEAR devices to the specified firmware versions that contain the security patch. If updates are unavailable, restrict administrative access to trusted IP addresses only and disable remote management where possible.

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 NETGEAR router model
    Locate the model number on the device label or in the router admin interface under a status or system information page
    Affected if The model is one of: Jnr1010, Jr6150, Jwnr2010, R6050, R6100, R6220, R7500, or R7800
  2. Check the installed firmware version
    Log into the router web management interface and navigate to the firmware version or router status page to find the current firmware build number
    Affected if The firmware version is below the fixed version for your model (Jnr1010/Jwnr2010: 1.1.0.44, Jr6150/R6050: 1.0.1.10, R6100: 1.0.1.16, R6220: 1.1.0.50, R7500: 1.0.0.112 or 1.0.3.20, R7800: 1.0.2.36)
  3. Determine if remote web management is enabled
    In the router admin interface, check the remote management or access control settings to see if web-based admin access is permitted from outside the local network
    Affected if Remote management is enabled, as this allows remote attackers to potentially trick authenticated users into submitting malicious CSRF requests

You are affected if your router model matches one of the eight listed models and your current firmware version is lower than the specified fixed version for that model.
