CVE-2024-50995
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 stack overflow via the share_name parameter at usb_remote_smb_conf.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 · high confidenceStack buffer overflow vulnerability in Netgear R8500 router firmware v1.0.2.160 in the usb_remote_smb_conf.cgi handler. The share_name parameter in POST requests lacks proper bounds checking, allowing attackers to overflow the stack and cause a denial of service by crashing the web 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 the router modelCheck the device label on the router or the web interface status page to confirm the model is Netgear R8500Affected if The device is not a Netgear R8500 router
-
Check the firmware versionLog into the router web interface, navigate to Administration or Advanced settings, and locate the firmware version displayed on the status or firmware update pageAffected if The installed firmware version is exactly 1.0.2.160
-
Determine if USB remote SMB sharing is enabledIn the router web interface, go to USB/Storage or ReadySHARE settings and check whether the remote SMB sharing feature is turned onAffected if USB remote SMB sharing is enabled and the firmware is 1.0.2.160
-
Confirm the vulnerable CGI endpoint is presentAccess the router administrative interface and verify that the usb_remote_smb_conf.cgi handler exists in the web server (this is typically found under the USB storage or remote access configuration areas)Affected if The usb_remote_smb_conf.cgi endpoint exists and responds to requests
A Netgear R8500 router running firmware version 1.0.2.160 with the USB remote SMB sharing feature enabled is affected by this 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 dataRestrict access to the router's administrative interface from untrusted networks; disable the USB remote SMB sharing feature if not needed; monitor for firmware updates from Netgear to address this vulnerability.
