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 R8500 v1.0.2.160, XR300 v1.0.3.78, R7000P v1.3.3.154, and R6400 v2 1.0.4.128 were discovered to contain a stack overflow via the pptp_user_ip parameter at bsw_pptp.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 buffer overflow vulnerability in the pptp_user_ip parameter of bsw_pptp.cgi on multiple Netgear router models (R8500, XR300, R7000P, R6400v2). Attackers can cause Denial of Service via crafted POST requests with oversized input.

MitigationApply available firmware updates from Netgear for affected models; if no update exists, consider network segmentation or replacing affected devices.

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
    Check the device label on the router or log into the web admin interface (typically 192.168.1.1) and look for the model number on the status or dashboard page.
    Affected if Model is R8500, XR300, R7000P, or R6400v2.
  2. Check installed firmware version
    In the web admin interface, navigate to the Router Update or Administration page to view the current firmware version. Alternatively, access the router via CLI and run the appropriate version command if available.
    Affected if Firmware version matches exactly 1.0.2.160 (R8500), 1.0.3.78 (XR300), 1.3.3.154 (R7000P), or 1.0.4.128 (R6400v2).
  3. Verify PPTP VPN is enabled
    In the web admin interface, look for VPN, PPTP, or Remote Access settings under the Advanced or VPN configuration section. Check if PPTP VPN is turned on or configured.
    Affected if PPTP VPN functionality is enabled or has been configured on the device.
  4. Confirm bsw_pptp.cgi is accessible
    Attempt to access the bsw_pptp.cgi endpoint via HTTP or HTTPS POST request to the router. This is typically found at /bsw_pptp.cgi or similar path under the router's web interface.
    Affected if The bsw_pptp.cgi endpoint responds to requests and accepts the pptp_user_ip parameter.

You are affected if you own one of the listed models AND the firmware version matches exactly AND PPTP VPN is enabled, as the buffer overflow only triggers when the pptp_user_ip parameter in bsw_pptp.cgi receives crafted input.
