I've just put up a paper detailing a new method of exploiting PL/SQL
injection flaws in Oracle and potential ways to protect against it. The
method entirely removes the requirement for an attacker to create functions
to be able to execute arbitrary sql. This should finally put to bed those
arguments about whether such and such a PL/SQL injection flaw is exploitable
in practice or not by a user with only the CREATE SESSION system privilege.
They all are. For anyone going to Blackhat Federal, this'll form part of my
talk. For anyone that wants, you can get a copy of the paper from
http://www.databasesecurity.com/ - it's called "Cursor Injection - A New
Method for Exploiting PL/SQL Injection and Potential Defences".
