CVE-2023-33264Network attack vector

Password disclosure via incomplete configuration masking

Published May 22, 2023 · Updated Jan 21, 2025

Credential exposure in Hazelcast 5.0.4 and earlier, 5.1 through 5.1.6, and 5.2 through 5.2.3 lets remote authenticated users view passwords. ConfigXmlGenerator writes LDAP system-user-password and simple-authentication user password values into generated XML without routing them through getOrMaskValue. Access requires an authenticated Management Center user; exposure is limited to configured authentication secrets returned in member configuration.
