'Name' => 'PeaZip <= 2.6.1 Zip Processing Command Injection',

'Description'=> %q{

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.
