CVE-2022-31861Public exploitNetwork attack vector

Administrator account takeover via unsafe audit-log email rendering

Published Sep 13, 2022 · Updated Aug 3, 2024

Stored XSS in ThingsBoard IoT Platform 3.3.4.1 and earlier allows remote authenticated users to steal administrator session tokens. A rejected profile update copies the crafted email value into the audit-log entity name, which the audit-log page renders as active HTML. A customer user must submit the value and a tenant administrator must view the audit log; script execution can expose the administrator's JWT and enable account takeover.
