RE: SQL Injection

Hi Gunter,

        I fail to see site who mititages SQL Injection via appropriate escaping
        can be susceptible to SQL Injection due to XSS.

        On that note, if XSS and SQL Injection are both possible, stopping XSS will
        not stop SQL Injection, however it may allow for some more sneaky implementations
        of it.

        I was attempting to clear up the thought that the other poster had who
        seemed to think by stopping XSS he would also stop SQL Injection, of course
        this isn't true.

      There are many many more possibilities for XSS then simply the 
      <script> tag, of course it depends on where the resulting string
      ends up, but simply replacing the <script> tag is *not* enough.

You may want to have a read of http://www.technicalinfo.net/papers/CSS.html
which goes into some of the alternitive atack vectors - and can readily
ported across for SQL insertion... In fact any code insertion attack
vectors.

Cheers,

Gunter
