SQL Injection Attack

Asked by pbguy in ColdFusion Application Server

Tags: sql, injection, coldfusion

Please tell me how to exploit this query with a SQL injection attack!

I've been reading about such attacks and I want to lock down my code a bit better.  But, for some reason I can't get my Coldfusion program to bite on the good old

' or '1'='1' --

as the password when I feed it in through a URL or the HTML form.  The query it calls is as follows:

<CFQUERY NAME="checklogin" DATASOURCE="..." USERNAME="..."  PASSWORD="...">

      SELECT       COUNT(*) AS usrcount
      FROM    accounts            
      WHERE      RTRIM( username )             = '#username#'       AND
                  RTRIM( pass )            = '#password#'
      GROUP BY username
</CFQUERY>

Intuitively this query should be hackable, am I mistaken?  Can anyone give me a SQLInjection hack that will break this SQL statement (it shouldn't be too hard to do?)

Also, any suggestions to sure-up my code would also be greatly appreciated (but mainly I want a hack example that works so I can fix my other sins ...)

Using MS SQL Server.  Please, nothing that will do damage (the apps are still my babies!)

Thanks for your input and comments!
