Summary

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 Cloud Foundry 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.

Risk Assessment

Egress rules can be bypassed to reach internal HTTP services, potentially leading to unauthorized access to internal network resources.

Recommendation

Upgrade Routing release to v0.372.0 or greater and CF Deployment to v55.0.0 or greater; review configured route-services.
