CVE-2024-28794Network attack vector

Credential disclosure via stored Web UI script

Published Jun 30, 2024 · Updated Aug 2, 2024

Stored XSS in the Web UI of IBM InfoSphere Information Server 11.7 allows remote authenticated users to expose session credentials. The Web UI stores attacker-supplied JavaScript and later renders it without adequate neutralization, although IBM has not identified the affected field or handler. Low-privileged access is required to plant the payload, and a second user must interact with the stored content to execute it in that user's trusted session.
