"The version of Spring Cloud Config running on the remote host is affected by a directory traversal vulnerability.
Spring Cloud Config, versions 2.2.x prior to 2.2.3, versions 2.1.x prior to 2.1.9, and older unsupported versions allow
applications to serve arbitrary configuration files through the spring-cloud-config-server module. A malicious user, or
attacker, can send a request using a specially crafted URL that can lead to a directory traversal attack.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
