This modules exploits a command injection vulnerability in the URL handler for

for the IBM Lotus Notes Client <= 8.5.3. The registered handler can be abused with

an specially crafted notes:// URL to execute arbitrary commands with also arbitrary

arguments. This module has been tested successfully on Windows XP SP3 with IE8,

Google Chrome 23.0.1271.97 m and IBM Lotus Notes Client 8.5.2.
