Unauthenticated Root Command Injection in Lantronix EDS5000 HTTP RPC Module
CVE-2025-67038 is an OS command injection vulnerability affecting Lantronix EDS5000 firmware version 2.1.0.0R3. The flaw is in the HTTP RPC module, which invokes a shell command to write logs when user authentication fails. In the vulnerable code path, the supplied username is directly concatenated into that shell command without sanitization or neutralization of shell metacharacters. An attacker can therefore place arbitrary shell syntax in the username parameter during a failed authentication attempt and cause attacker-controlled operating system commands to be executed. The injected commands run with root privileges, making this an unauthenticated remote root command execution issue.

A root-privilege command injection vulnerability in the Lantronix EDS5000 HTTP RPC module, where failed-login username logging passes unsanitized input into a shell command.
An unauthenticated OS command injection vulnerability affecting Lantronix EDS5000 series serial-to-IP converters. It is significant because researchers observed exploitation on a honeypot before public disclosure, suggesting attackers may have reverse-engineered the vendor patch to develop an exploit.
