CVE-2026-78037Network attack vector

Authenticated elevated command execution via web interface

Published Aug 27, 2026 · Updated Aug 27, 2026

OS command injection in Xiiaozet LK100W before 2.1.240 allows remote authenticated users to execute elevated operating system commands. The web-based management interface passes input into an OS-command path without neutralizing command elements; the endpoint and parameter are undisclosed. Low-privileged authenticated access is required, and successful execution can expose sensitive data, alter the appliance, or fully compromise it.
