Denial of Service (DoS)

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

Affected versions of this package are vulnerable to Denial of Service (DoS). The NiFi download token (one-time password) mechanism used a fixed cache size and did not authenticate a request to create a download token, only when attempting to use the token to access the content. An unauthenticated user could repeatedly request download tokens, preventing legitimate users from requesting download tokens.

How to fix Denial of Service (DoS)?

Upgrade org.apache.nifi:nifi-web-security to version 1.12.0 or higher.

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.

Session Fixation

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

Affected versions of this package are vulnerable to Session Fixation. When using an authentication mechanism other than PKI, when the user clicks Log Out, NiFi invalidates the authentication token on the client side but not on the server side. This permits the user's client-side token to be used for up to 12 hours after logging out to make API requests to NiFi.

How to fix Session Fixation?

Upgrade org.apache.nifi:nifi-web-security to version 1.10.0 or higher.
