|
||
|
|
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.
