Current installations of Pivotal's Spring Framework suffer from a potential remote code execution (RCE) issue. Depending on how the library is implemented within a product, it may or may not manifest, and authentication may be required.
Marking Red Hat JBoss Fuse 6 and Red Hat Fuse 7 as not affected, although versions before the documentation update (https://github.com/spring-projects/spring-framework/commit/5cbe90b2cd91b866a5a9586e460f311860e11cfa) where shipped at the time there is no use direct usage of org.springframework.remoting.httpinvoker.*
This was fixed upstream by detailing HttpInvoker endpoints should not be exposed to untrusted clients, these upstream changes would of been included with Fuse 6.3 R5 (https://access.redhat.com/errata/RHSA-2017:3115) which included a version change to 3.2.18 (3.2.17 containing the documentation fix)
