Description

mdserver-web is a simple Linux panel. From 0.18.0 to 0.18.4, mdserver-web has a front-end unauthorized remote command execution vulnerability. Due to the lack of authentication on the /modify_crond and /start_task interfaces, it is possible to modify the default built-in scheduled tasks and start them, achieving RCE.
