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 R7000P v1.3.3.154 was discovered to contain a stack overflow via the pptp_user_netmask parameter at 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 · moderate confidence

A stack-based buffer overflow vulnerability exists in Netgear R7000P firmware v1.3.3.154 in the pptp.cgi handler. The pptp_user_netmask parameter does not properly validate input length before copying to a fixed-size stack buffer, allowing an attacker to overflow the buffer with excessive data via a crafted POST request, causing a denial of service.

MitigationApply vendor firmware update if available; otherwise disable PPTP service or restrict administrative interface access to trusted networks 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 device model
    Access the router web interface or check the device label to confirm the model is Netgear R7000P
    Affected if Device is not a Netgear R7000P (not affected)
  2. Check firmware version
    Navigate to router web interface under Administration > Firmware Update or check the version displayed on the status page. Compare the installed version to 1.3.3.154
    Affected if Firmware version is exactly 1.3.3.154 (affected)
  3. Verify PPTP service accessibility
    Access the router web interface and check if PPTP/PPTP VPN settings are visible or configurable (usually under Advanced > VPN or similar path)
    Affected if PPTP service is present and accessible in the web interface (vulnerable attack surface available)
  4. Confirm administrative interface accessibility
    Check if the router administrative web interface (port 80/443) is reachable from untrusted networks by attempting access from an external IP or reviewing firewall rules
    Affected if Administrative interface is exposed to untrusted networks (higher exposure to exploitation)

You are affected if you are running Netgear R7000P firmware version 1.3.3.154 and the PPTP service is accessible via the router web interface.
