[~] The config file is expected to be at "/root/.rustscan.toml"
|

[!] File limit is lower than default batch size. Consider upping with --ulimit. May cause harm to sensitive servers
|
||||
[!] Your file limit is very small, which negatively impacts RustScan's speed. Use the Docker image, or up the Ulimit with '--ulimit 5000'.

Warning: OSScan results may be unreliable because we could not find at least 1 open and 1 closed port
|
||||
OS fingerprint not ideal because: Missing a closed TCP port so results incomplete
|
||||
Aggressive OS guesses: Linux 2.6.32 (95%), Linux 3.1 (95%), Linux 3.2 (95%), AXIS 210A or 211 Network Camera (Linux 2.6.17) (94%), ASUS RT-N56U WAP
|
||||
(Linux 3.4) (93%), Linux 3.16 (93%), Adtran 424RG FTTH gateway (92%), Linux 2.6.39 - 3.2 (92%), Linux 3.1 - 3.2 (92%), Linux 3.11 (92%)
|
||||
No exact OS matches for host (test conditions non-ideal).

I tried to use metasploit exploit for gitlab but found it was not vulnerable to because that was for version 12.8.x something and the version that was running on the site was 11.4.7 so looked for an exploit
|
||||
|
||||
<img src="https://imgur.com/M3WoNpj.png"/>
|
||||
|
||||
Ran the exploit
|
||||
|
||||

|
||||
|
||||
And got a shell
|
||||
|
||||

|
||||
|
||||
Stabilized the shell
|
||||
|
||||

|
||||
|
||||
We can see the users on gitlab with id
|
||||

Going to `/opt` folder found a directory called "backup"
|
||||
|
||||

|
||||
|
||||
Reading the docker.yml it seems that we are in a privileged container also found `root_pass` it had a password but it didn't worked
|
||||
|
||||
<img src="https://imgur.com/4wNBjWm.png"/>
|
||||
|
||||
Also I found another password
|
||||
|
||||
<img src="https://imgur.com/C34HxoC.png"/>
|
||||
|
||||
We got root for the container
|
||||
|
||||
<img src="https://imgur.com/LK8DquJ.png"/>
|
||||
|
||||
But still we need to breakout from this docker conatiner so use `fdisk -l`
|
||||
|
||||
<img src="https://imgur.com/eCB9xEO.png"/>
|
||||
|
||||
Now we can see that system is mounted on `/dev/sda2` so following hacktricks for docker escape we can mount this on a folder
|
||||

Transfer the `id_rsa` key you can find on the host machine's root folder

|
||||
|
||||
And we have a proper root on the box
