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 · unedited
An issue was discovered in Lantronix EDS5000 2.1.0.0R3. The SSH Client and SSH Server pages are affected by multiple OS injection vulnerabilities due to missing sanitization of input parameters. An attacker can inject arbitrary commands in delete actions of various objects, such as server keys, users, and known hosts. 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 confidence

This is a command injection vulnerability in Lantronix EDS5000 firmware version 2.1.0.0R3. The web interface's SSH Client and SSH Server pages fail to sanitize input parameters in delete actions for objects such as server keys, users, and known hosts, allowing authenticated attackers to inject arbitrary OS commands that execute with root privileges.

MitigationApply vendor-supplied firmware patch when available; until then, restrict network access to the device management interface and consider disabling SSH services if not essential for operations.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the device web interface or use SNMP/serial console to determine if the device is an Lantronix EDS5032, EDS5008, or EDS5016. Check the device info or system status page.
    Affected if The device is not one of these three models - the vulnerability does not apply.
  2. Check the installed firmware version
    Navigate to the device web interface System or Firmware section, or use the CLI command 'show version' or 'systeminfo' to retrieve the firmware version.
    Affected if The firmware version is exactly 2.1.0.0R3 - other versions are not affected by this specific CVE.
  3. Verify if SSH service is enabled
    In the web interface, go to the SSH Server or SSH Client configuration page. Check the service status or settings to confirm SSH is turned on.
    Affected if SSH is disabled - the vulnerable SSH Client and SSH Server pages are not accessible or active, reducing exposure.
  4. Confirm access to SSH management pages
    In the web interface, navigate to the SSH Client and SSH Server pages where delete actions for server keys, users, and known hosts can be performed. These are the specific pages containing the vulnerable input fields.
    Affected if These pages exist and are accessible to an authenticated user - the command injection vulnerability is present in the delete action parameters.

The device is affected if it is an EDS5032, EDS5008, or EDS5016 running firmware version 2.1.0.0R3 with the SSH web management interface accessible to authenticated users.
