HP Data Protector 8.10 Remote Command Execution

HP Data Protector 8.10 Remote Command Execution
Posted Mar 5, 2015
Authored by Christian Ramirez, Henoch Barrera | Site metasploit.com

This Metasploit module exploits a remote command execution on HP Data Protector 8.10. Arbitrary commands can be execute by sending crafted requests with opcode 28 to the OmniInet service listening on the TCP/5555 port. Since there is an strict length limitation on the command, rundll32.exe is executed, and the payload is provided through a DLL by a fake SMB server. This Metasploit module has been tested successfully on HP Data Protector 8.1 on Windows 7 SP1.
