CVE-2021-20069Public exploitNetwork attack vector

Stored script execution via unsanitized NTP servers

Published Feb 16, 2021 · Updated Aug 3, 2024

Stored XSS in RACOM M!DGE Firmware 4.4.40.105 allows remote authenticated users to execute scripts in a viewer's browser. The regionalSettings.php handler passes ntpServer and ntpServer2 to checkHost without sufficient sanitization, then stores and renders the values. Administrator-level access is required to submit the values, and script execution occurs when the regional settings page is viewed.
