What page architecture are you using: PHP, ASP, .Net 1.1 or .Net 2.0 or
are you using one of the standard CMS packages (Mambo, Plone, etc) ??
If you are using ASP.net 2.0 with MySQL (I am using this), I have
managed to implement the Membership / Role providers in my site using
MySQL as the provider. Using the login credentials you supplied, The
site rejects it as you have to have explicit username and password
(which is encrypted on creation in the DB) details to login.

Subject: 1' and '1' or '1
A user was able to log into my site using:
1' and '1' or '1
in the username and password box.
I ran the query
SELECT * FROM members WHERE name = '1' and '1' or '1' AND password = '1'
and '1' or '1'
And it returned all rows. Can someone explain to me why this happens,
and if the steps I took (replacing the ' with a blank space when the
user submits the login form) is enough to prevent a similar "hack"
Appreciate any feedback.
