'Name' => 'JIRA Issues Collector Directory Traversal',
'Description' => %q{
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.
