EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 1.0%, top 39% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
