Name of the Vulnerable Software and Affected Versions Apache NiFi versions prior to 1.8.0

Description The issue occurs when a client request to a cluster node is replicated to other nodes for verification, and the Content-Length is forwarded. Specifically, on a DELETE request, the body is 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.

Recommendations For Apache NiFi versions prior to 1.8.0, upgrade to Apache NiFi 1.8.0 or a later version to apply the fix that checks DELETE requests and overwrites non-zero Content-Length header values.
