Luigi Auriemma has reported a security issue in Crysis, which can be exploited by malicious people to disclose potentially sensitive information.
The problem is that the server/client sends a disconnect packet containing various information (e.g. IP address, nicknames, client status, etc...) when a keyexchange packet is received without an initial join packet.
The security issue is reported in version 18.104.22.16856. Other versions may also be affected.
Solution: Only play multi-player games on trusted, local networks.
