When a client request to a cluster node was replicated to other nodes in the cluster for verification, the Content-Length was forwarded. On a DELETE request, the body was ignored, but if the initial request had a Content-Length value other than 0, the receiving nodes would wait for the body and eventually timeout. Mitigation: The fix to check DELETE requests and overwrite non-zero Content-Length header values was applied on the Apache NiFi 1.8.0 release. Users running a prior 1.x release should upgrade to the appropriate release. Cuando una petición de cliente a un nodo del clúster se replicó a otros nodos en el clúster para verificarlos, se redireccionó el Content-Length. • https://nifi.apache.org/security.html#CVE-2018-17194 • CWE-20: Improper Input Validation •

The template upload API endpoint accepted requests from different domain when sent in conjunction with ARP spoofing + man in the middle (MiTM) attack, resulting in a CSRF attack.
