Xiaomi Mi Box Display Corruption
Posted on 27 November 2019
The vulnerability allows rescaling and corrupting the Xiaomi Mi Box (model: MIBOX3, build.id : MHC19) display without any privilege requirement, thus creating an opportunity for a non-privilege malicious app to disable the basic functionalities that the TV box is offering or can even be used for ransomware purpose - e.g., each time a target streaming app is launched, the malicious app can corrupt the display.
