-- raptor_oraextproc.sql - command exec via oracle extproc
-- Copyright (c) 2006 Marco Ivaldi  
--
-- 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).
--
-- See also: 
-- http://www.0xdeadbeef.info/exploits/raptor_oraexec.sql 
-- http://www.0xdeadbeef.info/exploits/raptor_orafile.sql 
--
-- 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
