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 genie_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

Stack overflow vulnerability in the genie_pptp.cgi endpoint of Netgear R8500, XR300, R7000P, and R6400 v2 routers. The pptp_user_ip parameter in POST requests lacks proper input validation, allowing attackers to overflow the stack and crash the device, causing Denial of Service.

MitigationReplace affected end-of-life routers with supported models or implement network segmentation to isolate vulnerable devices from untrusted networks, as no vendor firmware patches are available.

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
    Log into the router web interface or check the device label to confirm the exact model number (R8500, XR300, R7000P, or R6400v2).
    Affected if The device is any of these four models.
  2. Check firmware version
    In the router web interface, navigate to Administration > Firmware Update or similar section to view the current firmware version. Alternatively, check the router status page.
    Affected if The 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 configured
    In the router web interface, look for VPN settings, PPTP, or Advanced Wireless settings. Check if PPTP VPN has been enabled or configured on the device.
    Affected if PPTP VPN functionality is enabled or any PPTP-related configuration exists on the router.
  4. Test genie_pptp.cgi endpoint accessibility
    Attempt to access or send a crafted POST request to http://<router_ip>/genie_pptp.cgi with the pptp_user_ip parameter. Use a tool like curl: curl -X POST -d "pptp_user_ip=TEST" http://<router_ip>/genie_pptp.cgi
    Affected if The endpoint responds or accepts POST requests, indicating the vulnerable CGI is present and reachable.

A user is affected if they own one of the four listed Netgear models running the exact firmware versions specified AND have PPTP functionality accessible on their network.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Replace affected end-of-life routers with supported models or implement network segmentation to isolate vulnerable devices from untrusted networks, as no vendor firmware patches are available.

Recommended fix Moderate confidence

Netgear firmware version newer than the affected release (check Netgear support for latest available version for your specific model)

  1. 1. Identify the exact model of your Netgear router from the affected models: R8500, XR300, R7000P, or R6400v2
  2. 2. Navigate to the Netgear support website (www.netgear.com) and locate the firmware download section for your specific router model
  3. 3. Check for available firmware versions newer than your current version (R8500: >1.0.2.160, XR300: >1.0.3.78, R7000P: >1.3.3.154, R6400v2: >1.0.4.128)
  4. 4. Download the latest stable firmware release available for your router model
  5. 5. Access your router's web management interface and navigate to the Administration or Settings section
  6. 6. Locate the firmware update option and upload the downloaded firmware file
  7. 7. Wait for the firmware upload and installation to complete - do not power off the router during this process
  8. 8. After reboot, verify the router is functioning normally and confirm the new firmware version is installed
Caveat Router firmware updates can sometimes reset configuration to defaults; backup current settings before upgrading and reapply after upgrade
