 'Name' => 'Idera Up.Time Monitoring Station 7.0 post2file.php Arbitrary File Upload',
 'Description' => %q{
 This module exploits an arbitrary file upload vulnerability found within the Up.Time
 monitoring server 7.2 and below. A malicious entity can upload a PHP file into the
 webroot without authentication, leading to arbitrary code execution.

 Although the vendor fixed Up.Time to prevent this vulnerability, it was not properly
 mitigated. To exploit against a newer version of Up.Time (such as 7.4), please use
 exploits/multi/http/uptime_file_upload_2.
