Technical details

An OS command injection vulnerability exists in Lantronix EDS5000 firmware version 2.1.0.0R3. The flaw is located in the handling of the 'tunnel' parameter when an authenticated user attempts to terminate a tunnel connection. Due to insufficient input sanitization, an attacker can inject shell commands that are executed with root privileges. While the CISA-ADP CVSS score is 8.8 (Low Privileges), some vendor documentation suggests a score of 7.2 (High Privileges); however, the vulnerability consistently results in full system compromise. Lantronix has released firmware version 2.2.0.0R1 to address this issue.
