NGSSoftware Insight Security Research Advisory

Name: Trigger abuse of MDSYS.SDO_TOPO_DROP_FTBL
Systems Affected: Oracle 10g R1 and R2 (10.1.0.5 and 10.2.0.2)
Severity: High
Vendor URL: http://www.oracle.com/
Author: David Litchfield [ davidl () ngssoftware com ]
Reported: 23rd July 2008
Date of Public Advisory: 13th January 2009
Advisory number: #NISR13012009
CVE: CVE-2008-3979

Overview
********
Oracle has just released a fix for a flaw that, when exploited,
allows a low
privileged authenticated database user to gain MDSYS privileges.
This can be
abused by an attacker to perform actions as the MDSYS user.

Details
*******
MDSYS.SDO_TOPO_DROP_FTBL is one of the triggers that forms part of

the
Oracle Spatial Application. It is vulnerable to SQL injection.
When a user
drops a table the trigger fires. The name of the table is embedded

in a
dynamic SQL query which is then executed by the trigger. Note that

the
Oracle advisory states that the attacker requires the DROP TABLE
and CREATE
PROCEDURE privileges. This is not the case and only CREATE SESSION


privileges are required.

Fix Information
***************
Oracle was alerted to this flaw on the 23rd July 2008. A patch has

now been
made available:
