CVE-2022-43928Network attack vector

Sensitive-memory disclosure via immutable Java strings

Published Apr 7, 2023 · Updated Feb 10, 2025

Information disclosure in IBM Toolbox for Java within IBM Db2 Mirror 7.4 and 7.5 allows remote authenticated users to read sensitive data. The setup and GUI pass sensitive values through immutable Java strings, leaving sensitive contents resident in process memory until garbage collection. Exploitation requires privileged access to that memory, and the published impact is limited to confidentiality.
