# An issue was discovered in Lantronix EDS5000 2.1.0.0R3

The Lantronix EDS5000 device-server has a code injection flaw in its username parameter that lets an attacker inject OS commands. Injected commands run with root privileges, and CISA lists it as actively exploited.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

Check whether any EDS5000 units are in your inventory and which firmware version they run; the sources do not give a command or file to check the version.

## Fix

Apply the vendor mitigation or patch per Lantronix instructions; the sources do not name a fixed version.
If no mitigation is available, discontinue use of the device as CISA directs.

## From the sources

Lantronix EDS5000 contains a code injection vulnerability that could allow attackers to inject arbitrary OS commands into the username parameter. Injected commands are executed with root privileges.

CISA required action: Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
