CVE-2023-33846Network attack vector

Credential disclosure via reflected Web UI script injection

Published Jun 8, 2023 · Updated Jan 6, 2025

Reflected XSS in affected IBM CICS TX Web UIs allows remote authenticated users to expose credentials through injected JavaScript. The Web UI reflects user-supplied JavaScript into trusted-session pages without neutralizing it; IBM has not identified the affected parameter or handler. Exploitation requires low-privileged access and a separate user to interact with the crafted content, limiting the reported consequence to credential disclosure and page modification.
