Re: Oracle SQL Injection vulnerability

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.

Hello,

Wild guess but can the username be numeric only
rather than
alphanumeric as everyone expects? People often
misconceive that the
username field as alpha while it may very well not
be ...That would
explain why you are still getting the "ORA-01756:
quoted string not
properly terminated" even when you appear to
terminating correctly.
what if you input "123 or 1=1--" (strip ") in the
username field?
