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.
AnalysisAI
Remote code execution in mdserver-web Linux panel versions 0.18.0 through 0.18.4 allows unauthenticated remote attackers to execute arbitrary system commands by exploiting unprotected scheduled task management endpoints. Attackers can modify built-in cron jobs via the /modify_crond interface and trigger execution through /start_task without any authentication, achieving complete system compromise. …
