The Optoma CinemaX P2 projector (firmware TVOS-04.24.010.04.01, Android 8.0.0) exposes Android Debug Bridge (ADB) on TCP port 5555 over the network without requiring authentication. The device is configured with ro.adb.secure=0, which disables RSA key verification. Additionally, a functional su binary exists at /system/xbin/su that grants root privileges without authentication. An attacker on the same network can connect to the device via ADB, obtain a shell, and escalate to root privileges, gaining complete control of the device. This allows extraction of stored WiFi credentials, installation of persistent malware, and access to all device data.
