So an attacker who gained rights on a monitored system to extend the agent could create and modify files in the monitoring Checkmk site with certain modifications of the agent. The creation or modification of files in the Checkmk site was done with rights of the Checkmk site user. This problem is now solved by a better validation of hostnames of piggybacked hosts. With this change only these characters are allowed in Piggybacked hostnames: <tt>0-9a-zA-Z_.-</tt>. These are exactly the same characters that Checkmk normally allows when creating hostnames. A special feature of Piggyback hostnames is that all illegal hostnames are replaced by "_". This change means that Piggyback hosts created with now invalid characters will have to be created differently after this change so that they can continue to be monitored.
