CVE-2024-22356Network attack vector

Privileged information disclosure through log and trace files

Published Mar 26, 2024 · Updated Aug 5, 2024

Information disclosure in IBM App Connect Enterprise and Integration Bus for z/OS allows privileged users to read sensitive data. Affected releases write potentially sensitive information to log or trace files without preventing privileged users from reading it; IBM has not identified the specific logged fields or triggering operations. App Connect Enterprise 11.0.0.1 through 11.0.0.23 and 12.0.1.0 through 12.0.9.0, plus Integration Bus for z/OS 10.1 through 10.1.0.2, are exposed only after a user obtains high privileges, and the documented impact is read-only disclosure.
