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
Norton Core prior to v278 may be susceptible to an arbitrary code execution issue, which is a type of vulnerability that has the potential of allowing an individual to execute arbitrary commands or code on a target machine or in a target process. Note that this exploit is only possible with direct physical access to the device.

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 · moderate confidence

Norton Core router firmware versions prior to v278 contain an arbitrary code execution vulnerability that allows an attacker with direct physical access to the device to execute arbitrary commands or code. This is a physical attack vector requiring the attacker to have direct contact with the device.

MitigationUpgrade Norton Core firmware to v278 or later. Additionally, restrict physical access to the router to prevent unauthorized physical contact with the device.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Norton Core router hardware
    Locate your router and confirm it is a Norton Core router (spherical design with blue LED ring)
    Affected if Device is not a Norton Core router - this CVE does not apply
  2. Access router firmware version via mobile app
    Open the Norton Core mobile app, go to Settings > Router Settings > About, and note the firmware version number displayed
    Affected if Firmware version shown is less than 278 (for example, 275, 276, or 277)
  3. Access router firmware version via web interface
    Connect to the router admin panel at https://192.168.1.1 or the configured IP, navigate to Settings > Router Status, and record the firmware version
    Affected if Firmware version shown is less than 278 (for example, 275, 276, or 277)
  4. Check physical access exposure
    Evaluate whether unauthorized individuals could have had direct physical contact with the router hardware (including reset button access, USB ports, or device tampering)
    Affected if Physical access by untrusted parties is possible AND firmware version is below 278

You are affected if you own a Norton Core router with firmware version lower than 278 and the device could be accessed by untrusted individuals with physical contact capability.
