Name of the Vulnerable Software and Affected Versions Spring Cloud Gateway versions prior to 4.2.1 and versions 5.0.0 and 5.1.0.

Description When configuring SSL bundles in Spring Cloud Gateway using the spring.ssl.bundle configuration property, the configuration was silently ignored, and the default SSL configuration was used instead. This could lead to weaker cryptography than intended, potentially enabling Man-in-the-Middle (MitM) attacks.

Recommendations Upgrade to Spring Cloud Gateway version 4.2.1 or later. Alternatively, upgrade to version 5.0.1 or 5.1.1.
