Penetration Testing: Re: Oracle SQL Injection vulnerability

[Attari Attari <c70n3 () yahoo co in>]

Hey Zed,

You hit the bulls eye. 

Now I gave 123 OR 1=1-- as the injection in username
field.. I don't get the same error on a previous line
but a new error further down the code which says:

"ORA-01722: invalid number"

Looks like the query earlier is:

SELECT COUNT(*) FROM TABLENAME  WHERE ID = '" &
txtUser.Text & "' and PASSWORD =  '"...

Now this query is fired fine. But the execution breaks
in the next line that says (yes error's are not
hidden):
 
If CInt(cmd.ExecuteScalar()) > 0 

Suggestions what's going wrong here?

Thanks a ton guys.
