CVE-2018-17194 Information

Description

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.
