What is CVE-2026-80145?

A command injection vulnerability exists in Lantronix devices, including SLC8000 and EMG series, allowing authenticated attackers with service permissions to execute arbitrary shell commands as root. This vulnerability arises from the handling of unsanitized user input in the 'set cifs password' command, which calls system() without proper validation. Successful exploitation can lead to a significant compromise of device confidentiality, integrity, and availability, potentially impacting connected devices downstream.
