SCA: security update for org.apache.pulsar:pulsar-client (GHSA-c5fp-x2h5-vjv7)

medium Tenable Self-Hosted Container Security Plugin ID 413678

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Delayed TLS hostname verification in the Pulsar Java Client and the Pulsar Proxy make each client
 vulnerable to a man in the middle attack. Connections from the Pulsar Java Client to the Pulsar
 Broker/Proxy and connections from the Pulsar Proxy to the Pulsar Broker are vulnerable. Authentication
 data is sent before verifying the server’s TLS certificate matches the hostname, which means
 authentication data could be exposed to an attacker. An attacker can only take advantage of this
 vulnerability by taking control of a machine 'between' the client and the server. The attacker must then
 actively manipulate traffic to perform the attack by providing the client with a cryptographically valid
 certificate for an unrelated host. Because the client sends authentication data before performing hostname
 verification, an attacker could gain access to the client’s authentication data. The client eventually
 closes the connection when it verifies the hostname and identifies the targeted hostname does not match a
 hostname on the certificate. Because the client eventually closes the connection, the value of the
 intercepted authentication data depends on the authentication method used by the client. Token based
 authentication and username/password authentication methods are vulnerable because the authentication data
 can be used to impersonate the client in a separate session. This issue affects Apache Pulsar Java Client
 versions 2.7.0 to 2.7.4; 2.8.0 to 2.8.3; 2.9.0 to 2.9.2; 2.10.0; 2.6.4 and earlier. (CVE-2022-33681)
