Improper Certificate Validation in maven/org.apache.pulsar/pulsar

Identifiers

CVE-2022-33683

Package Slug

maven/org.apache.pulsar/pulsar

Vulnerability

Improper Certificate Validation

Description

Apache Pulsar Brokers and Proxies create an internal Pulsar Admin Client that does not verify peer TLS certificates, even when tlsAllowInsecureConnection is disabled via configuration. The Pulsar Admin Client's intra-cluster and geo-replication HTTPS connections is vulnerable to man in the middle attacks, which could leak authentication data, configuration data, and any other data sent by these clients. 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. This issue affects Apache Pulsar Broker and Proxy 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.

Affected Versions

All versions before 2.7.5, all versions starting from 2.8.0 before 2.8.4, all versions starting from 2.9.0 before 2.9.3, version 2.10.0

Solution

Upgrade to versions 2.7.5, 2.8.4, 2.9.3 or above.
