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
Netgear XR300 v1.0.3.78, R7000P v1.3.3.154, and R6400 v2 1.0.4.128 was discovered to contain a stack overflow via the pppoe_localip parameter at wizpppoe.cgi. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted POST request.

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

Stack-based buffer overflow in the wizpppoe.cgi web handler allows attackers to crash the router via an oversized pppoe_localip parameter in a crafted POST request, causing a denial of service condition.

MitigationApply vendor firmware updates when available; until then, restrict access to the device's web management interface to trusted networks only to reduce attack surface.

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 router model
    Access the router's web administration interface or check the device label/menu to confirm the exact model number (Xr300, R7000p, or R6400v2)
    Affected if Router is NOT one of these three models - the vulnerability only affects Netgear Xr300, R7000p, and R6400v2
  2. Check firmware version
    Log into the router web interface and navigate to the Administration or Firmware Upgrade section to view the current firmware version, or use the router's status page
    Affected if Firmware version matches exactly 1.0.3.78 (Xr300), 1.3.3.154 (R7000p), or 1.0.4.128 (R6400v2)
  3. Verify web management interface accessibility
    Attempt to access the router's web interface from the network (typically http://routerlogin.net or http://192.168.1.1)
    Affected if Web interface is reachable - the vulnerability is exploited via HTTP POST requests to the wizpppoe.cgi handler
  4. Confirm wizpppoe.cgi endpoint exists
    Send a request to http://<router_ip>/wizpppoe.cgi or check if the endpoint responds (even with an error)
    Affected if The wizpppoe.cgi endpoint is present and responds - this is the vulnerable web handler
  5. Check PPPoE configuration status
    Navigate to the router's Internet/WAN settings in the web interface to see if PPPoE is enabled and configured
    Affected if PPPoE is configured - the vulnerable parameter pppoe_localip is related to PPPoE settings

You are affected if you own a Netgear Xr300, R7000p, or R6400v2 router running exactly version 1.0.3.78, 1.3.3.154, or 1.0.4.128 respectively, and the web management interface with wizpppoe.cgi is accessible on your network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
