How to Fix CVE-2020-1940

To remediate this vulnerability, upgrade all affected Oak core 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.jackrabbit:oak-core fixed: 1.24.0 
<dependency>
    <groupId>org.apache.jackrabbit</groupId>
    <artifactId>oak-core</artifactId>
    <version>1.24.0</version>
</dependency>
org.apache.jackrabbit:oak-core fixed: 1.10.8 
<dependency>
    <groupId>org.apache.jackrabbit</groupId>
    <artifactId>oak-core</artifactId>
    <version>1.10.8</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.jackrabbit

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-1940, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Oak core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.24.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.jackrabbit 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-212: Improper Removal of Sensitive Information Before Storage or Transfer, where the product stores, transfers, or shares a resource that contains sensitive information, but it does not properly remove that information before the product makes the resource available to unauthorized actors. In Oak core, 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

The optional initial password change and password expiration features present in Apache Jackrabbit Oak 1.2.0 to 1.22.0 are prone to a sensitive information disclosure vulnerability. The code mandates the changed password to be passed as an additional attribute to the credentials object but does not remove it upon processing during the first phase of the authentication. In combination with additional, independent authentication mechanisms, this may lead to the new password being disclosed.
