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 was discovered to contain a command injection vulnerability in the sysNewPasswd parameter at admin_account.cgi. This vulnerability allows attackers to execute arbitrary OS commands via a crafted 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

Command injection vulnerability in Netgear R8500 router's admin_account.cgi interface. The sysNewPasswd parameter lacks proper input sanitization, allowing arbitrary OS command execution through crafted requests. This is a pre-authentication vulnerability accessible via the router's web interface.

MitigationApply available firmware update from Netgear. If no update exists, restrict access to the router's admin interface via network segmentation or firewall rules, and consider replacing the end-of-life device.

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 the router model
    Log into the router web interface or check the device label to confirm the model is Netgear R8500
    Affected if The device is not a Netgear R8500, then it is not affected by this specific CVE
  2. Check the firmware version
    Navigate to the router admin interface (typically at 192.168.1.1) and go to Administration > Firmware Update or check the status page to identify the installed firmware version
    Affected if The installed firmware version is exactly 1.0.2.160, then this specific version is affected by the vulnerability
  3. Verify network exposure of the admin interface
    Determine if the router web interface (port 80/443) is accessible from the internet or an untrusted network segment by reviewing router port forwarding rules, firewall configurations, or performing an external port scan
    Affected if The admin_account.cgi interface is reachable from an untrusted network (such as directly from the internet), the vulnerability is exploitable in that exposure context
  4. Confirm the admin_account.cgi endpoint exists
    Access the URL http://<router-ip>/admin_account.cgi or https://<router-ip>/admin_account.cgi to verify the endpoint is present and responds
    Affected if The endpoint responds (with or without authentication), the vulnerable interface is exposed on the device

A Netgear R8500 router running firmware version 1.0.2.160 with its web admin interface (specifically the admin_account.cgi endpoint) accessible from an untrusted network is affected by this command injection vulnerability.

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

Apply available firmware update from Netgear. If no update exists, restrict access to the router's admin interface via network segmentation or firewall rules, and consider replacing the end-of-life device.
