HP Data Protector Arbitrary Remote Command Execution

HP Data Protector Arbitrary Remote Command Execution
Posted Aug 7, 2013
Authored by Alessandro Di Pinto, Claudio Moletta | Site metasploit.com

This Metasploit module allows execution of a command with an arbitrary number of arguments on Microsoft Windows operating systems. The trick calls a 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 execute only a single command without parameters, as provided by already existing exploits. It is possible to exploit the security issue in order to run any command inside the target system.
