Name Modify Data via Inline Views (8107967) [DB09] Systems Affected Oracle 9i - 10g Rel. 2 Severity High Risk Category Unauthorized Access Vendor URL http://www.oracle.com/ Author Alexander Kornbrust (ak at red-database-security.com) Advisory 18 October 2006 (V 1.00) Advisory http://www.red-database-security.com/advisory/oracle_modify_data_via_inl ine_views.html
Updates, deletes and inserts are possible with least-privilege via inline views. A user with create session only can insert/update/delete data (e.g. the dual table). This bug is similar but not identical to the bug which was fixed in the July 2006 CPU (Modify Data via views). No workarounds available.
delete from (specially crafted inline view) insert into (specially crafted inline view) update (specially crafted inline view)
