CVE-2025-33014Network attack vector

Browser compromise via unsafe QueueWatch links

Published Jul 18, 2025 · Updated Aug 18, 2025

Link injection in IBM Sterling B2B Integrator and File Gateway allows remote authenticated users to compromise a victim's browser. The QueueWatch UI fails to validate request parameters before using an external URL in a link that leaves window.opener accessible. Exploitation requires low-privileged access and a victim to follow the crafted link, allowing the external page to expose sensitive browser data or perform unauthorized browser actions.
