CVE-2017-6036
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 Server-Side Request Forgery issue was discovered in Belden Hirschmann GECKO Lite Managed switch, Version 2.0.00 and prior versions. The web server receives a request, but does not sufficiently verify that the request is being sent to the expected destination.
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 confidenceServer-Side Request Forgery vulnerability in Belden Hirschmann GECKO Lite Managed switch web server (v2.0.00 and prior). The web application does not properly validate user-supplied URLs before making server-side requests, allowing an attacker to trick the device into making requests to arbitrary internal or external resources.

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 modelCheck the device label, web interface login page, or SNMP sysDescr for 'Belden Hirschmann Gecko Lite Managed Switch' or similar Gecko product namingAffected if Device is not a Belden Hirschmann Gecko Lite Managed Switch - not affected
-
Determine firmware versionAccess the web interface System > Firmware or System > Information page, or query via SNMP sysDescr or sysVersion OID, and compare to 2.0.00Affected if Firmware version is 2.0.00 or prior - likely affected
-
Verify web server is enabledConfirm the web interface is accessible on HTTP/HTTPS ports (typically 80/443) and not disabled in the device network settingsAffected if Web server is accessible and device is Gecko Lite with firmware <= 2.0.00
-
Inspect for URL input featuresBrowse the web interface menus for any feature accepting URLs, such as remote logging, firmware update from URL, ping/traceroute tools, or external authentication settingsAffected if URL input fields exist in the web interface and firmware is <= 2.0.00
The device is affected if it is a Belden Hirschmann Gecko Lite Managed Switch running firmware version 2.0.00 or prior, with the web server enabled and accessible.

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 dataImplement strict URL validation and allowlisting for server-side requests. Restrict outbound connections to trusted destinations and disable unnecessary external request capabilities in the web interface.
