Lantronix EDS5000 2.1.0.0R3 HTTP RPC Command Injection Root Exec
CVE-2025-67038 Published on March 11, 2026
Lantronix EDS5000, G520, and X300 OS Command Injection
An issue was discovered in Lantronix EDS5000 2.1.0.0R3. The HTTP RPC module executes a shell command to write logs when user's authentication fails. The username is directly concatenated with the command without any sanitization. This allow attackers to inject arbitrary OS commands into the username parameter. Injected commands are executed with root privileges.
Known Exploited Vulnerability
This Lantronix EDS5000 Code Injection Vulnerability is part of CISA's list of Known Exploited Vulnerabilities. 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.
The following remediation steps are recommended / required by June 26, 2026: 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).
