Description

When configuring SSL bundles in Spring Cloud Gateway by using the configuration property spring.ssl.bundle, the configuration was silently ignored and the default SSL configuration was used instead.

Affected Spring Products and Versions

Spring Cloud Gateway:

• 4.2.0

Note: The 4.2.x branch is no longer under open source support. If you are using Spring Cloud Gateway 4.2.0 and are not an enterprise customer, you can upgrade to any Spring Cloud Gateway 4.2.x release newer than 4.2.0 available on Maven Centeral. Ideally if you are not an enterprise customer, you should be upgrading to 5.0.2 or 5.1.1 which are the current supported open source releases.

Mitigation

Users of affected versions should upgrade to the corresponding fixed version.
