Cross Site Scripting (XSS) vulnerability in Things Board 3.4.1 allows remote attackers to escalate privilege via crafted URL to the Audit Log.

ThingsBoard 3.4.1 could allow a remote authenticated attacker to achieve Vertical Privilege Escalation. A Tenant Administrator can obtain System Administrator dashboard access by modifying the scope via the scopes parameter.

ThingsBoard 3.4.1 could allow a remote attacker to gain elevated privileges because hard-coded service credentials (usable for privilege escalation) are stored in an insecure format. (To read this stored data, the attacker needs access to the application server or its source code.)
