Improper Authentication

Affected versions of this package are vulnerable to Improper Authentication through the /pingpong endpoint. An attacker can connect to the endpoint without requiring authentication, potentially leading to denial of service due to the WebSocket Proxy accepting any connections and excessive data transfer through misuse of the WebSocket ping/pong feature.

How to fix Improper Authentication?

Upgrade org.apache.pulsar:pulsar-websocket to version 2.10.5, 2.11.2, 3.0.1 or higher.

  • M
Man-in-the-Middle (MitM)

Affected versions of this package are vulnerable to Man-in-the-Middle (MitM) due to the TLS hostname verification which cannot be enabled in the Pulsar Broker's Java Client, the Pulsar Broker's Java Admin Client, the Pulsar WebSocket Proxy's Java Client, and the Pulsar Proxy's Admin Client, leaving intra-cluster connections and geo-replication connections vulnerable to man in the middle attacks, which could leak credentials, configuration data, message data, and any other data sent by these clients. The vulnerability is for both the pulsar+ssl protocol and HTTPS.

How to fix Man-in-the-Middle (MitM)?

Upgrade org.apache.pulsar:pulsar-websocket to version 2.7.5, 2.8.4, 2.9.3, 2.10.1 or higher.
