Yeah... you are vulnerable to sql-injection.
You have to replace the single quotes with two quotes in the postdata
received from the search form.

ASP Ex: Replace(Request.Querystring("SOMETHING"), "'", "' '")

Byeee ;-)

P.S.
Excuse me for my english :S

Oggetto: [Full-Disclosure] sql injection question

Quick question for the list, if I may,

We have a third party application that we are piloting for using as web
store front end.

I have no idea on programming sql at all, but have read of some of the sql
injection techniques on this list.

In the search box on the app, by inserting  ' followed by a space, the
following message is generated:

----------------------------------------------------------------------------

Also, the password for SA is stored in clear text in the site in a text
config file. This would not strike me as being sensible.

These are both ringing alarm bells !

>From this info, would you assume it would be easy for someone skilled in sql
injection to get unauthorised access to the database?.. or is it not that
simple?

The input seems to be filtered correctly on the logon.asp, as entering these
characters has no apparent effect.

TIA

Richard
