Description
The vulnerability allows a remote attacker to perform cache poisoning attacks.
The vulnerability exists due to incorrect processing of HTTP requests that rely on HTTP parameter values. If a client is requesting a URL with parameter "value=A", the parameter will be processed and the response will be cached. If another client is requesting the same URL but with a different parameter "value=B", the request will be answered with the initial response ("value=A") during the caching time (for 112 seconds).
