CVE-2011-4608
First published: Tue Dec 13 2011(Updated: )
It was found that mod_cluster allowed worker nodes to register on any vhost, regardless of the security constraints applied to other vhosts. In a typical environment there will be one vhost configured internally for worker nodes, and another configured externally for serving content. A remote attacker could exploit this flaw by registering a worker node via an external vhost that is not configured to apply security constraints, then use this worker node to serve malicious content, intercept credentials and hijack user sessions.
