Windows Escalate Task Scheduler XML Privilege Escalation

This module exploits the Task Scheduler 2.0 XML 0day exploited by Stuxnet. When processing task files, the Windows Task Scheduler only uses a CRC32 checksum to validate that the file has not been tampered with. Also, In a default configuration, normal users can read and write the task files that they have created. By modifying the task file and creating a CRC32 collision, an attacker can execute arbitrary commands with SYSTEM privileges. NOTE: Thanks to webDEViL for the information about disable/enable.
