Description

Querybook is a user interface for querying big data. Prior to version 3.31.1, there is a vulnerability in Querybook’s rich text editor that enables users to input arbitrary URLs without undergoing necessary validation. This particular security flaw allows the use of javascript: protocol which can potentially trigger arbitrary client-side execution. The most extreme exploit of this flaw could occur when an admin user unknowingly clicks on a cross-site scripting URL, thereby unintentionally compromising admin role access to the attacker. A patch to rectify this issue has been introduced in Querybook version 3.31.1. The fix is backward compatible and automatically fixes existing DataDocs. There are no known workarounds for this issue, except for manually checking each URL prior to clicking on them.

Technical Analysis

Entered URL through Draft.js entity data (props.contentState.getEntity(props.entityKey).getData()) in querybook/webapp/lib/richtext/ index.tsx (line 13) misses validation of URL schema using Safelist (‘http:’, ‘https:’), resulting in client-side XSS at <Link to={url} newTab> (line 15), enabling ACE when exploited.
