How to Fix CVE-2024-27317
To remediate this vulnerability, upgrade all affected Apache 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-functions-worker</artifactId>
<version>2.10.6</version>
</dependency>
<dependency>
<groupId>org.apache.pulsar</groupId>
<artifactId>pulsar-functions-worker</artifactId>
<version>2.11.4</version>
</dependency>
<dependency>
<groupId>org.apache.pulsar</groupId>
<artifactId>pulsar-functions-worker</artifactId>
<version>3.0.3</version>
</dependency>
<dependency>
<groupId>org.apache.pulsar</groupId>
<artifactId>pulsar-functions-worker</artifactId>
<version>3.1.3</version>
</dependency>
<dependency>
<groupId>org.apache.pulsar</groupId>
<artifactId>pulsar-functions-worker</artifactId>
<version>3.2.1</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.pulsar
How to Check if You Are Affected
To determine whether your Java application is affected by CVE-2024-27317, 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 Apache Pulsar in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.10.6), 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Apache 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.

"details" : "In Pulsar Functions Worker, authenticated users can upload functions in jar or nar files. These files, essentially zip files, are extracted by the Functions Worker. However, if a malicious file is uploaded, it could exploit a directory traversal vulnerability. This occurs when the filenames in the zip files, which aren't properly validated, contain special elements like \"..\", altering the directory path. This could allow an attacker to create or modify files outside of the designated extraction directory, potentially influencing system behavior. This vulnerability also applies to the Pulsar Broker when it is configured with \"functionsWorkerEnabled=true\".\n\nThis issue affects Apache Pulsar versions from 2.4.0 to 2.10.5, from 2.11.0 to 2.11.3, from 3.0.0 to 3.0.2, from 3.1.0 to 3.1.2, and 3.2.0. \n\n2.10 Pulsar Function Worker users should upgrade to at least 2.10.6.\n2.11 Pulsar Function Worker users should upgrade to at least 2.11.4.\n3.0 Pulsar Function Worker users should upgrade to at least 3.0.3.\n3.1 Pulsar Function Worker users should upgrade to at least 3.1.3.\n3.2 Pulsar Function Worker users should upgrade to at least 3.2.1.\n\nUsers operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions.",
