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

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; --

or something similar?  Couldn't I EXEC some system sprocs this way too?
How much damage/rooting can be done here?  I need to present a detailed
report to the admins.


Hi Francesco,
That all depends on the permissions that the user you are acting as has.
In your case it depends on the permissions of the first user in the
"Users" table.


Thanks,

Francesco
