Technical details

A code injection flaw exists in the loadstring() function within usr/lib/lua/luci/controller/api/zrUsb.lua that processes unsanitized input from the /api/ZRUsb/get_usb_result endpoint. The vulnerability requires valid HTTP Basic Auth credentials (root user) and control over temporary files (/tmp/run/usb_list_result or /tmp/run/old_usb_list_result) to execute arbitrary Lua code on the device.
