Android Open Source Platform (AOSP) Browser UXSS

Created
05/30/2018

Description

This module exploits a Universal Cross-Site Scripting (UXSS) vulnerability present in all versions of Android's open source stock browser before 4.4, and Android apps running on < 4.4 that embed the WebView component. If successful, an attacker can leverage this bug to scrape both cookie data and page contents from a vulnerable browser window. If your target URLs use X-Frame-Options, you can enable the "BYPASS_XFO" option, which will cause a popup window to be used. This requires a click from the user and is much less stealthy, but is generally harmless-looking. By supplying a CUSTOM_JS parameter and ensuring CLOSE_POPUP is set to false, this module also allows running aribtrary javascript in the context of the targeted URL. Some sample UXSS scripts are provided in data/exploits/uxss.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/gather/android_stock_browser_uxss
msf auxiliary(android_stock_browser_uxss) > show actions
    ...actions...
msf auxiliary(android_stock_browser_uxss) > set ACTION < action-name >
msf auxiliary(android_stock_browser_uxss) > show options
    ...show and set options...
msf auxiliary(android_stock_browser_uxss) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
