CVE-2025-67038: Lantronix EDS5000 Code Injection Vulnerability
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.
This vulnerability affects the Lantronix EDS5000 and permits injection of arbitrary operating system commands via the username parameter. Commands execute with root privileges, which can result in full control of the device.
IT and security teams should prioritize identification and mitigation because the weakness provides an attacker with privileged access on an exposed system.
How it works
The issue is tracked under CWE-78 and CWE-94. These describe failures to neutralize special elements in operating system commands and improper control of code generation.
An attacker supplies crafted input in the username parameter. The device then executes the supplied commands on the underlying operating system with root privileges.
Am I affected? How to find it in your systems
Locate every Lantronix EDS5000 instance through asset inventories, network scans, or configuration management databases. Confirm the exact versions and settings against the vendor advisory.
Review authentication and input-handling logs for anomalous entries that could indicate attempted or successful command injection. Specific telemetry indicators must be validated against vendor guidance.
How to remediate
Apply mitigations exactly as stated in the vendor instructions. This is the required first action.
- Ensure all actions align with CISA BOD 26-04 requirements for prioritizing security updates based on risk.
- Evaluate each asset’s internet exposure and apply the corresponding BOD 26-04 controls.
- Adhere to CISA’s Forensics Triage Requirements when investigating any suspected activity.
If you can't patch immediately
Apply BOD 26-04 guidance for cloud services or discontinue use of the product when mitigations cannot be implemented.
- Restrict network access to the device through segmentation to reduce external reach.
- Monitor for indicators of compromise using established forensic triage procedures.
