CVE-2025-45493
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 EX8000 V1.0.0.126 is vulnerable to Command Injection via the iface parameter in the action_bandwidth function.
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 confidenceThe Netgear EX8000 mesh router firmware version 1.0.0.126 contains a command injection vulnerability in the action_bandwidth function. The iface parameter is not properly sanitized before being used in a system call, allowing an authenticated attacker to inject arbitrary shell commands.

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 device modelAccess the router's web management interface and check the device model information, typically found on the status or administration page. Alternatively, check the device label or packaging for the EX8000 model designation.Affected if The device is a Netgear EX8000 mesh router
-
Check the installed firmware versionLog into the router's web interface and navigate to the Administration or Firmware Update section to view the current firmware version. The version number should be displayed prominently.Affected if The firmware version is exactly 1.0.0.126
-
Verify the action_bandwidth function existsAccess the router's web interface and locate the bandwidth settings or QoS configuration section. The action_bandwidth function is typically accessed via a CGI endpoint such as /cgi-bin/bandwidth.cgi or similar in the web interface.Affected if The bandwidth management feature is present and accessible in the web interface
-
Confirm web interface is network-accessibleAttempt to access the router's web login page from a connected device using the router's IP address (commonly 192.168.1.1 or 192.168.0.1). Verify the HTTP service is listening.Affected if The router's HTTP/HTTPS web interface is reachable from the network
-
Check authentication statusDetermine if default admin credentials are in use or if the web management interface is accessible without authentication. Attempt to log in or check if any authentication is required to access the bandwidth settings.Affected if The web interface accepts authentication (even with default credentials) and the bandwidth feature is accessible to authenticated users
You are affected if you have a Netgear EX8000 router running firmware version 1.0.0.126 with its web interface accessible to users who can authenticate to access the action_bandwidth function.
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 the vendor firmware update from Netgear when available. If a patch is unavailable, consider network segmentation to limit exposure to authenticated users.
