CVE-2024-50993
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 · uneditedNetgear 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 confidenceCommand 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the router modelLog into the router web interface or check the device label to confirm the model is Netgear R8500Affected if The device is not a Netgear R8500, then it is not affected by this specific CVE
-
Check the firmware versionNavigate 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 versionAffected if The installed firmware version is exactly 1.0.2.160, then this specific version is affected by the vulnerability
-
Verify network exposure of the admin interfaceDetermine 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 scanAffected 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
-
Confirm the admin_account.cgi endpoint existsAccess the URL http://<router-ip>/admin_account.cgi or https://<router-ip>/admin_account.cgi to verify the endpoint is present and respondsAffected 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.
Generated from the published advisory. Verify against your own configuration.
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.
From vendor dataApply 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.
