How to Fix CVE-2015-7501

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

commons-collections:commons-collections fixed: 3.2.2
<dependency>
    <groupId>commons-collections</groupId>
    <artifactId>commons-collections</artifactId>
    <version>3.2.2</version>
</dependency>
org.apache.commons:commons-collections4 fixed: 4.1
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-collections4</artifactId>

net.sourceforge.collections:collections-generic fixed: Latest secure release
<dependency>
    <groupId>net.sourceforge.collections</groupId>
    <artifactId>collections-generic</artifactId>
    <version>Latest secure release</version>

    <groupId>org.apache.servicemix.bundles</groupId>
    <artifactId>org.apache.servicemix.bundles.collections-generic</artifactId>
    <version>Latest secure release</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=commons-collections

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2015-7501, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=commons-collections

Analyze the terminal output to locate any version of Commons collections in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.2.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=commons-collections 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-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Commons collections, 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

It was found that the Apache commons-collections library permitted code execution when deserializing objects involving a specially constructed chain of classes. A remote attacker could use this flaw to execute arbitrary code with the permissions of the application using the commons-collections library.
