Ratpack is a toolkit for creating web applications. In versions prior to 1.9.0, a user supplied
X-Forwarded-Hostheader can be used to perform cache poisoning of a cache fronting a Ratpack server if the cache key does not include theX-Forwarded-Hostheader as a cache key. Users are only vulnerable if they do not configure a customPublicAddressinstance. For versions prior to 1.9.0, by default, Ratpack utilizes an inferring version ofPublicAddresswhich is vulnerable. This can be used to perform redirect cache poisoning where an attacker can force a cached redirect to redirect to their site instead of the intended redirect location. The vulnerability was patched in Ratpack 1.9.0. As a workaround, ensure thatServerConfigBuilder::publicAddresscorrectly configures the server in production. - References
