Description
This module exploits an arbitrary command execution vulnerability in Webmin
1.900 and lower versions. Any user authorized to the "Upload and Download"
module can execute arbitrary commands with root privileges.
In addition, if the 'Running Processes' (proc) privilege is set the user can
accurately determine which directory to upload to. Webmin application files
can be written/overwritten, which allows remote code execution. The module
has been tested successfully with Webmin 1.900 on Ubuntu v18.04.
Using GUESSUPLOAD attempts to use a default installation path in order to
trigger the exploit.
