Description

The disclosed vulnerability allows a remote user to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote authenticated user can send a specially crafted MQTT packet which has an XSS payload as client-id or topic name and execute arbitrary HTML and script code in administrator's browser in context of vulnerable website, as the code execution is triggered via the diagram plugin, queue node and the info section in the admin console.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
