CVE-2023-45303 · GHSA-6pgr-j9v4-xfvv
- Affected
- Maven org.thingsboard:thingsboard < 3.5
- Fixed in
- 3.5· Vendor fix available
- Issue
- ThingsBoard before 3.5 allows Server-Side Template Injection if users are allowed to modify an email template, because Apache FreeMarker supports freemarker.template.utility.Execute for content sent to the /api/admin/settings endpoint.
Recommended action: Upgrade to 3.5 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
