In detail, the following flaw was determined:

  • Custom actions can be added to the MGE frontend without authentication required (pane_actionbutton.php)
  • Actions can be executed (tested) without authentication required (exec_action.php)

Impact:

This problem can lead to a remote file execution vulnerability. It can allow an attacker to add and execute custom actions. The commands to be executed are included within the added action.

The vulnerability is present in MGE Network Shutdown Module software versions prior 3.10 build 13.
