What the flaw is

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's description

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.
