Route Services can be leveraged to send app traffic to network destinations outside of an apps 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).
Weakness
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.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Cf-deployment | Cloudfoundry | 0.0.2 (including) | 55.0.0 (excluding) |
| Routing_release | Cloudfoundry | 0.118.0 (including) | 0.372.0 (excluding) |
Extended Description
Attackers might be able to spoof the intended endpoint from a different system or process, thus gaining the same level of access as the intended endpoint. While this issue frequently involves authentication between network-based clients and servers, other types of communication channels and endpoints can have this weakness.
