CVE-2020-9390 - Stored cross-site scripting (Web Content tile)

CVE: CVE-2020-9390

Description

Cross-site scripting (XSS) enable attackers to bring malicious content into a website or application.

Before SquaredUp DS version 4.6, stored XSS was possible for Web Content tiles. Exploiting this vulnerability was possible for SquaredUp DS users who can create dashboards.

Users could create a dashboard with a Web Content tile that embeds an iframe pointing to malicious JavaScript. For example, it was possible to point to a page that emulates session timeout and asks for credentials when a user views the dashboard.

Fix

JavaScript is now blocked from iframes in Web Content tiles.

What should you do?

If you are using a SquaredUp DS version earlier than 4.6, update to version 4.6 or later.
