'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.
