Description

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).

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality none, integrity none, availability low.
