How to Fix CVE-2023-37544

To remediate this vulnerability, upgrade all affected Pulsar websocket dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.apache.pulsar:pulsar-websocket fixed: 2.10.5 
<dependency>
    <groupId>org.apache.pulsar</groupId>
    <artifactId>pulsar-websocket</artifactId>
    <version>2.10.5</version>
</dependency>
org.apache.pulsar:pulsar-websocket fixed: 2.11.2 
<dependency>
    <groupId>org.apache.pulsar</groupId>
    <artifactId>pulsar-websocket</artifactId>
    <version>2.11.2</version>
</dependency>
org.apache.pulsar:pulsar-websocket fixed: 3.0.1 
<dependency>
    <groupId>org.apache.pulsar</groupId>
    <artifactId>pulsar-websocket</artifactId>
    <version>3.0.1</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.apache.pulsar

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-37544, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.pulsar

Analyze the terminal output to locate any version of Pulsar websocket in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.10.5), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.pulsar command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Pulsar websocket, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Improper Authentication vulnerability in Apache Pulsar WebSocket Proxy allows an attacker to connect to the /pingpong endpoint without authentication. This issue affects Apache Pulsar WebSocket Proxy: from 2.8.0 through 2.8.*, from 2.9.0 through 2.9.*, from 2.10.0 through 2.10.4, from 2.11.0 through 2.11.1, 3.0.0. The known risks include a denial of service due to the WebSocket Proxy accepting any connections, and excessive data transfer due to misuse of the WebSocket ping/pong feature. 2.10 Pulsar WebSocket Proxy users should upgrade to at least 2.10.5. 2.11 Pulsar WebSocket Proxy users should upgrade to at least 2.11.2. 3.0 Pulsar WebSocket Proxy users should upgrade to at least 3.0.1. 3.1 Pulsar WebSocket Proxy users are unaffected. Any users running the Pulsar WebSocket Proxy for 2.8, 2.9, and earlier should upgrade to one of the above patched versions.
