How to Fix CVE-2018-1317

To remediate this vulnerability, upgrade all affected Zeppelin 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.zeppelin:zeppelin fixed: 0.8.0 
<dependency>
    <groupId>org.apache.zeppelin</groupId>
    <artifactId>zeppelin</artifactId>
    <version>0.8.0</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.zeppelin

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2018-1317, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Zeppelin in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.8.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.zeppelin 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 Zeppelin, 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 Zeppelin prior to 0.8.0 the cron scheduler was enabled by default and could allow users to run paragraphs as other users without authentication.
