CVE-2024-51022
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 XR300 v1.0.3.78 was discovered to contain a stack overflow via the ssid parameter in bridge_wireless_main.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 confidenceA stack buffer overflow vulnerability exists in the ssid parameter of the bridge_wireless_main.cgi script on Netgear XR300 firmware v1.0.3.78. Attackers can trigger the overflow via a crafted POST request containing an oversized ssid value, causing the device to crash and resulting in a Denial of Service.

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 device modelCheck the device label or access the web interface to confirm the model is Netgear XR300Affected if Device is not a Netgear XR300 - this CVE does not apply
-
Check firmware versionAccess the router web interface (usually at 192.168.1.1) and navigate to Administration > Firmware Update or check the status page to find the firmware version, or use telnet/ssh if enabled to run 'cat /etc/os-release' or 'nvram get firmware_version'Affected if Firmware version is not exactly 1.0.3.78 - only this specific version is affected
-
Verify web interface is accessibleAttempt to reach the router's HTTP/HTTPS web interface on the local networkAffected if Web interface is not accessible - the attack vector requires HTTP access to bridge_wireless_main.cgi
-
Check if wireless bridge feature is configuredLocate the bridge wireless settings page in the router web interface (typically under Wireless or Advanced > Wireless settings) and determine if any wireless bridge SSID is configuredAffected if No wireless bridge SSID is configured - the vulnerable bridge_wireless_main.cgi script may not be invoked
The device is affected only if it is a Netgear XR300 running firmware version 1.0.3.78, its web interface is accessible, and wireless bridge functionality with an SSID is configured, making the bridge_wireless_main.cgi script reachable for exploitation.

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 any available firmware update from Netgear for the XR300 device. If no patch is available, restrict network access to the device's web interface and disable wireless bridge functionality if not required.
