I have just discovered that I can successfully inject the following SQL:

' OR 1=1; --

into the Username field of a logon form on a "secure" site in my
corporate network (Windows 2000, SQL 7.0).  When I do this, leaving the
password field blank, I am logged into the system as the first user in
the "Users" table in the DB which is being authenticated against.  LOL.

If I can get that far, can't I theoretically:

' OR 1=1; DELETE Users; --


With proper SQL, yes (the above is not).

or something similar? Couldn't I EXEC some system sprocs this way too?

Not normally, no.

How much damage/rooting can be done here?

No rooting, but you should be able to create a privileged account for yourself or update the password of some other user so you can use that. Google for SQL injections. You should find about 20000 pages.


 I need to present a detailed
report to the admins.


Yeah, right.

Thanks,
