How to Fix CVE-2022-24280
To remediate this vulnerability, upgrade all affected Pulsar dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.apache.pulsar</groupId>
<artifactId>pulsar</artifactId>
<version>2.7.5</version>
</dependency><dependency>
<groupId>org.apache.pulsar</groupId>
<artifactId>pulsar</artifactId>
<version>2.8.3</version>
</dependency><dependency>
<groupId>org.apache.pulsar</groupId>
<artifactId>pulsar</artifactId>
<version>2.9.2</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.pulsarHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2022-24280, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.pulsarAnalyze the terminal output to locate any version of Pulsar in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.7.5), 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Pulsar, 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.

When the Apache Pulsar Proxy component is used, it is possible to attempt to open TCP/IP connections to any IP address and port that the Pulsar Proxy can connect to. An attacker could use this as a way for DoS attacks that originate from the Pulsar Proxy's IP address. It hasn’t been detected that the Pulsar Proxy authentication can be bypassed. The attacker will have to have a valid token to a properly secured Pulsar Proxy. This issue affects Apache Pulsar Proxy versions 2.7.0 to 2.7.4; 2.8.0 to 2.8.2; 2.9.0 to 2.9.1; 2.6.4 and earlier.",
