Summary
In Lantronix EDS5000 version 2.1.0.0R3, the HTTP RPC module executes a shell command to write logs when user authentication fails. The username is directly concatenated with the command without any sanitization, allowing attackers to inject arbitrary OS commands into the username parameter. Injected commands are executed with root privileges.
Risk Assessment
An attacker can gain full control of the device by executing arbitrary commands with administrator privileges, potentially compromising network integrity and device management.
Recommendation
Immediately update the device firmware to the latest version if a patch is available, and restrict access to the HTTP RPC interface to trusted networks only.
