|
|
This module exploits the command injection vulnerability of MailCleaner Community Edition product. An authenticated user can execute an
|
|
operating system command under the context of the web server user which is root.
|
|
|
|
/admin/managetracing/search/search endpoint takes several user inputs and then pass them to the internal service which is responsible for executing
|
|
operating system command. One of the user input is being passed to the service without proper validation. That cause a command injection vulnerability.
