How to Fix CVE-2023-27602

To remediate this vulnerability, upgrade all affected Linkis 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.linkis:linkis fixed: 1.3.2 
<dependency>
    <groupId>org.apache.linkis</groupId>
    <artifactId>linkis</artifactId>
    <version>1.3.2</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.linkis

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-27602, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Linkis in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.3.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.linkis 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-434: Unrestricted Upload of File with Dangerous Type, where the product allows the upload or transfer of dangerous file types that are automatically processed within its environment. In Linkis, 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

In Apache Linkis <=1.3.1, The PublicService module uploads files without restrictions on the path to the uploaded files, and file types. We recommend users upgrade the version of Linkis to version 1.3.2.  For versions <=1.3.1, we suggest turning on the file path check switch in linkis.properties `wds.linkis.workspace.filesystem.owner.check=true` `wds.linkis.workspace.filesystem.path.check=true`
