It allows an external user to select and communicate with modules that contain severe vulnerabilities. Therefore, E\u003csup\u003e2\u003c/sup\u003eVA enables research on the applicability of *standard* binary exploitation techniques to Android apps, which call native functions.\n\nE\u003csup\u003e2\u003c/sup\u003eVA stands for *Exploitation Experience (with) Vulnerable App*. It is the foundation of a series of [blog posts](https://lolcads.github.io/posts/2022/11/diving_into_the_art_of_userspace_exploitation_under_android/) that describe exploitation of some already existing vulnerable modules. \n\n![E2VA Architecture](https://raw.githubusercontent.com/fkie-cad/eeva/main/assets/eeva.svg)\n\nThe app runs on a Pixel 3 emulator (without Google Play for root access), running Android 12 (API level 31), and an x86 - 64 architecture. Other setups have not yet been tested!\n\n## Installation\n\n**Warning**: This app requests a [runtime - permission](https://developer.android.com/reference/android/provider/Settings.html#ACTION_MANAGE_OVERLAY_PERMISSION) that it needs to stay active for e.g. long debugging sessions. As this app contains **actual vulnerabilities**, there is always a risk of some third party attacking the app, getting code execution and rampaging through your system. Therefore, launch E\u003csup\u003e2\u003c/sup\u003eVA in a controlled environment, which does not contain any important and/or personal information that must not be lost and/or leaked. (or accept the risk)\n\nCurrently, there are two ways of installing E\u003csup\u003e2\u003c/sup\u003eVA.\n\n### APK\n\nUse the `.apk` file, which is (hopefully kept) up to date with the current version of E\u003csup\u003e2\u003c/sup\u003eVA. This is the *intended* route, i.e. taking perspective of an attacker, it is more likely to have access to an `.apk` - file than the app's original source code.\n\n### Build via *Android Studio*\n\nAs this is just the pushed [*Android Studio*](https://developer.android.com/studio) project of E\u003csup\u003e2\u003c/sup\u003eVA, one can just build the app, create own modules, optimize communication between external client and E\u003csup\u003e2\u003c/sup\u003eVA etc.\n\n## Emulator Hardware Profile\n\nUp to this point, an AVD (Android Virtual Device) to run E\u003csup\u003e2\u003c/sup\u003eVA can be created by either using a predefined hardware profile in Android Studio (called *Pixel 3*), or by importing the hardware profile in this repository.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffkie-cad%2Feeva","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffkie-cad%2Feeva","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffkie-cad%2Feeva/lists"}
