Technical details
An OS command injection vulnerability exists in the HTTP RPC module of Lantronix EDS5000 firmware version 2.1.0.0R3. The vulnerability occurs when the system handles failed authentication attempts; the provided username is directly concatenated into a shell command used for logging without prior sanitization. A remote, unauthenticated attacker can exploit this by submitting a malicious username containing shell metacharacters. Successful exploitation results in arbitrary command execution with root-level privileges. Lantronix has released firmware version 2.2.0.0R1 to address this issue.
