Sensitive information disclosure through diagnostic output

Published Nov 30, 2021 · Updated Sep 16, 2024

Information disclosure in IBM MQ Appliance 9.2 CD and 9.2 LTS allows local users to obtain sensitive data through diagnostic output. The diagnostic-generation path includes sensitive information in its output, but IBM has not identified the affected fields or underlying code path. Exploitation requires local access, and the reported consequence is limited to reading sensitive information without integrity or availability impact.
