CVE-2025-56101Public exploitNetwork attack vector

Authenticated command execution via module_get POST data

Published Dec 11, 2025 · Updated Dec 11, 2025

OS command injection in Ruijie M18 firmware EW_3.0(1)B11P226 allows remote authenticated users to execute arbitrary system commands. The module_get handler in /usr/local/lua/dev_sta/networkConnect.lua fails to neutralize shell metacharacters in crafted POST data before invoking an operating-system command. Authenticated network access to the Lua service is required, and the same behavior is reported in RG-EW1200R ReyeeOS301 firmware.
