This module exploits a UXSS vulnerability present in all versions of
|
||||
Android's open source stock browser before Android 4.4.
|
||||
|
||||
By default it is assumed that all of the TARGET_URLS can be loaded
|
||||
into iframes. To steal from a URL that uses the X-Frame-Options HTTP
|
||||
header to prevent framing, enable the BYPASS_XFO option to enable
|
||||
a one-click exploit of the first URL in TARGET_URLS.
