CVE-2023-28529Network attack vector

Credential disclosure via stored Web UI scripts

Published May 19, 2023 · Updated Jan 21, 2025

Stored cross-site scripting in IBM InfoSphere Information Server 11.7 allows remote authenticated users to expose credentials through its Web UI. The Web UI stores user-supplied JavaScript and later executes it inside a trusted session; IBM has not identified the affected form, field, or handler. High-privilege access is required to plant the script, which can read credentials available to the affected session and alter displayed content.
