🔥 EXPLOITATION🔥
Starting with the webapp. Supplying the username and password fields with a tick ' gives us a SQL error suggesting SQL injection attack here.
taking this a step further using the usernames found from the enum4linux output and injecting a true MYSQL statement into the password field to try and login
Username: John
Password: ' OR 1=1 #
We can login 😎
Johns password is there for the taking.
I logged in again with the same technique to get roberts password
Not much else we can do with the LigGoat so i moved on the try and login to SSH with the creds obtained.
We can login as John :D
After trying to move around I was kicked out . The same was experience as Robert
After a while playing with the limited shell and research
Exploiting the echo command we break out into a bash shell
echo os.system(‘/bin/bash’)
🔥PRIV ESCALATION 🔥
Now we need to get root
Looking around the system and in /var/www
Inside the file checklogin.php with clear-text login creds 🗝️ 🗝️ 🗝️
Theres no root password either.
- Note - Never store creds on a system in clear-text. this will be picked up quick by someone who knows what they are doing. You can hash the value in config files using something like MD5
Now we can jump into mysql
Got a little stuck here and banged my head against a wall for a bit. I found the following guide https://www.adampalmer.me/iodigitalsec/2013/08/13/mysql-root-to-system-root-with-udf-for-windows-and-linux/
had a quick look for the file needed to do the business
looks good. followed the guide and got root 😎 😎 😎
Never underestimate and forget the power of google. Step away from the problem for a while use google. Dont give up :D
Hope this was useful.
