Detailsinfo

A vulnerability, which was classified as problematic, was found in CloudFoundry Routing Release and CF Deployment (affected version unknown). This affects an unknown functionality of the component Route Service. The manipulation with an unknown input leads to a communication channel to intended endpoints vulnerability. CWE is classifying the issue as CWE-923. The product establishes a communication channel to (or from) an endpoint for privileged or protected operations, but it does not properly ensure that it is communicating with the correct endpoint. This is going to have an impact on availability. The summary by CVE is:

Route Services can be leveraged to send app traffic to network destinations outside of an app's configured egress rules. As a result, a malicious developer with access to Cloudfoundry could configure a route-service that would allow it to send requests to HTTP services on internal networks reachable by the Gorouter, which may not have previously had direct access from outside networks, or from the application. Routing release: affected from v0.118.0 through v0.371.0 (inclusive); upgrade to v0.372.0 or greater. CF Deployment: affected from v0.0.2 through v54.14.0 (inclusive); upgrade to v55.0.0 or greater (includes routing_release v0.372.0).
