CVE-2025-67037
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 · uneditedAn issue was discovered in Lantronix EDS5000 2.1.0.0R3. An authenticated attacker can inject OS commands into the "tunnel" parameter when killing a tunnel connection. Injected commands are executed with root privileges.
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 confidenceAuthenticated command injection in Lantronix EDS5000 2.1.0.0R3 allows attackers to inject OS commands via the 'tunnel' parameter when terminating tunnel connections. Injected commands execute with root privileges.

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 Lantronix EDS device modelAccess the device web interface or check the device label/menu for the exact model number (EDS5032, EDS5008, or EDS5016)Affected if Device model is not one of the three affected models
-
Check firmware versionNavigate to the device web interface System Information or Status page, or use the CLI command 'show version' to retrieve the installed firmware versionAffected if Firmware version is exactly 2.1.0.0 (note: only this exact version is affected)
-
Verify tunnel termination feature is in useCheck device configuration for active tunnel connections or tunnel termination settings - look for Tunnel, Serial Tunnel, or similar configuration sections in the web UI or CLIAffected if Tunnel termination functionality is configured or active on the device
-
Confirm device management interface accessibilityCheck if the device web or CLI management interface is reachable from network segments accessible to users - verify authentication is required for accessAffected if Device admin interface is accessible without proper access controls (the flaw requires authenticated access)
The device is affected only if it is an Lantronix EDS5032/EDS5008/EDS5016 running exactly firmware version 2.1.0.0, has tunnel termination configured, and the management interface is accessible to untrusted users.
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 dataIsolate affected devices on restricted network segments, enforce strict access controls, and apply vendor-supplied firmware patches when available. Implement WAF/IPS rules to detect command injection patterns if network isolation is not feasible.
