What is CVE-2023-45303?

ThingsBoard prior to version 3.5 contains a vulnerability that permits Server-Side Template Injection, particularly when users are allowed to modify email templates. This flaw stems from the use of Apache FreeMarker, which supports the execution of templates through the freemarker.template.utility.Execute utility, specifically affecting content submitted to the /api/admin/settings endpoint. If exploited, this vulnerability could allow attackers to execute arbitrary commands on the server, potentially leading to unauthorized access and data compromise.
