CVE-2025-4135
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 · uneditedA vulnerability was found in Netgear WG302v2 up to 5.2.9 and classified as critical. Affected by this issue is the function ui_get_input_value. The manipulation of the argument host leads to command injection. The attack may be launched remotely. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceA command injection vulnerability in the ui_get_input_value function of Netgear WG302v2 wireless access points (versions up to 5.2.9) allows remote attackers to inject arbitrary OS commands via the host parameter without sanitization.

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 device web management interface or check the physical device label for the model number WG302v2Affected if Device is a Netgear WG302v2 wireless access point
-
Check the firmware versionLog into the device web interface and navigate to Administration > Firmware Upgrade or check the status page for the firmware version numberAffected if Firmware version is 5.2.9 or lower (any version up to and including 5.2.9)
-
Determine if the management interface is network-accessibleVerify whether the device web interface (HTTP/HTTPS on ports 80 or 443) is reachable from network segments beyond the local administration networkAffected if The device management web interface is accessible from network segments that are not restricted to trusted administration IPs
You are affected if you have a Netgear WG302v2 device running firmware version 5.2.9 or lower with its web management interface accessible to untrusted networks, since the command injection flaw in the ui_get_input_value function can be exploited via the host parameter.

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 dataIsolate the device on a restricted network segment and limit management interface access to trusted IPs only; since the device is end-of-life with no vendor patch, consider replacing with a supported model.
