How to Fix CVE-2006-3936

To remediate this vulnerability, upgrade all affected Opencms 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.opencms:opencms-core fixed: 6.2.2 
<dependency>
    <groupId>org.opencms</groupId>
    <artifactId>opencms-core</artifactId>
    <version>6.2.2</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.opencms

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2006-3936, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.opencms

Analyze the terminal output to locate any version of Opencms core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.2.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.opencms 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-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
