CVE-2023-30441Network attack vector

Sensitive-data disclosure through undisclosed cryptographic flaws

Published Apr 29, 2023 · Updated Jan 30, 2025

Information disclosure in IBM SDK, Java Technology Edition 8.0.7.0 through 8.0.7.11 allows remote attackers to read sensitive data. IBM has disclosed only that combined flaws in JSSE and IBMJCEPlus expose the data; the incorrect cryptographic operation remains unpublished. Exposure requires the runtime to act as a TLS server with IBMJCEPlus ranked above IBMJCE, the default order for 8.0.7.0 and later.
