Information Exposure

org.apache.nifi:nifi-web-security is a system to process and distribute data.

Affected versions of this package are vulnerable to Information Exposure. The flow fingerprint factory generated flow fingerprints which included sensitive property descriptor values. In the event a node attempted to join a cluster and the cluster flow was not inheritable, the flow fingerprint of both the cluster and local flow was printed, potentially containing sensitive values in plaintext.

How to fix Information Exposure?

Upgrade org.apache.nifi:nifi-web-security to version 1.11.1 or higher.

Deserialization of Untrusted Data

Apache NiFi is a system to process and distribute data.

Affected versions of this package are vulnerable to Deserialization of Untrusted Data.

Any authenticated user (valid client certificate but without ACL permissions) could upload a template which contained malicious code and caused a denial of service via Java deserialization attack. The fix to properly handle Java deserialization was applied on the Apache NiFi 1.4.0 release. Users running a prior 1.x release should upgrade to the appropriate release.

How to fix Deserialization of Untrusted Data?

Upgrade Apache NiFi to 1.4.0 version or higher.
