Cloud Foundry Routing Release, versions prior to 0.197.0, contains GoRouter, which allows malicious clients to send invalid headers, causing caching layers to reject subsequent legitimate clients trying to access the app.
A function or operation returns an incorrect return value or status code that does not indicate the true result of execution, causing the product to modify its behavior based on the incorrect result.
The product acts as an intermediary HTTP agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed HTTP requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination.
