Loading vulnerability…
CVE-2020-0082 is a vulnerability in the ExternalVibration component of Android (ExternalVibration.java), where unsafe deserialization allows a local attacker to activate an arbitrary intent. This flaw enables escalation of privilege to the system_server context without requiring user interaction or additional execution privileges. The vulnerability affects Android 10.

This repository is a proof-of-concept (PoC) exploit for CVE-2020-0082, a local privilege escalation vulnerability in Android 10 (system_server) due to unsafe deserialization in ExternalVibration. The exploit is implemented as an Android application with two main Java classes: MainActivity and AuthService. MainActivity provides a UI button that, when clicked, launches an intent targeting the system's AddAccountSettings component, passing a crafted account type. AuthService implements a custom account authenticator that manipulates the Android account authentication flow. The core exploit logic involves crafting a malicious Parcel (via MainActivity.generate()) that abuses the deserialization flaw to inject a privileged intent (such as CALL_PRIVILEGED with tel:911 or ACTION_REBOOT) into system_server, resulting in privilege escalation. The repository includes standard Android project files, build scripts, and resource files. The exploit is local-only, requiring installation and execution on a vulnerable Android 10 device. No network endpoints are involved; all attack vectors are local and rely on Android IPC and intent mechanisms.
