CVE-2023-50312

Adjacent information disclosure via ignored TLS configuration

Published Mar 1, 2024 · Updated Apr 22, 2025

Weak outbound TLS handling in IBM WebSphere Application Server Liberty 17.0.0.3 through 24.0.0.2 allows adjacent attackers to read protected data. Outbound TLS handling fails to apply an unspecified user configuration, leaving connections protected less strongly than configured. Exploitation requires an adjacent network position; IBM reports no integrity or availability impact, and the affected setting is undisclosed.
