How to Fix CVE-2024-4701

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

com.netflix.genie:genie-web fixed: 4.3.18 
<dependency>
    <groupId>com.netflix.genie</groupId>
    <artifactId>genie-web</artifactId>
    <version>4.3.18</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=com.netflix.genie

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-4701, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.netflix.genie

Analyze the terminal output to locate any version of Genie web in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.3.18), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.netflix.genie 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 Genie web, 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

### Overview Path Traversal Vulnerability via File Uploads in Genie ### Impact Any Genie OSS users running their own instance and relying on the filesystem to store file attachments submitted to the Genie application may be impacted. Using this technique, it is possible to write a file with any user-specified filename and file contents to any location on the file system that the Java process has write access - potentially leading to remote code execution (RCE). Genie users who do not store these attachments locally on the underlying file system are not vulnerable to this issue. ### Description Genie's API accepts a multipart/form-data file upload which can be saved to a location on disk. However, it takes a user-supplied filename as part of the request and uses this as the filename when writing the file to disk. Since this filename is user-controlled, it is possible for a malicious actor to manipulate the filename in order to break out of the default attachment storage path and perform path traversal. Using this technique it is possible to write a file with any user specified name and file contents to any location on the file system that the Java process has write access to. ### Patches This path traversal issue is fixed in Genie OSS v4.3.18. This issue was fixed in https://github.com/Netflix/genie/pull/1216 and https://github.com/Netflix/genie/pull/1217 and a [new release](https://github.com/Netflix/genie/releases/tag/v4.3.18) with the fix was created. Please, upgrade your Genie OSS instances to the new version.
