CVE-2019-16273Public exploitNetwork attack vector

Root code execution via unauthenticated network ADB

Published Jan 6, 2020 · Updated Aug 5, 2024

Improper authentication in DTEN D5 and D7 devices before 1.3.4 allows remote attackers to execute arbitrary code as root through ADB. The Android firmware exposes its ADB daemon to the network without authenticating clients, and the daemon grants an incoming connection a root shell. Network reachability is sufficient to administer the device, alter its software, or covertly capture Zoom meeting audio, video, and screen content.
