Apache NiFi Improper Input Validation vulnerability
CVE-2018-17194 · GHSA-43fp-vwwg-qgv6
- Affected
- Maven org.apache.nifi:nifi-framework-cluster >= 1.0.0, <= 1.7.1
- Fixed in
- 1.8.0· Vendor fix available
- Issue
- 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.
Recommended action: Upgrade to 1.8.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
