How to Fix CVE-2024-41667

To remediate this vulnerability, upgrade all affected Openam oauth2 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.openidentityplatform.openam:openam-oauth2 fixed: 15.0.4 
<dependency>
    <groupId>org.openidentityplatform.openam</groupId>
    <artifactId>openam-oauth2</artifactId>
    <version>15.0.4</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.openidentityplatform.openam

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-41667, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.openidentityplatform.openam

Analyze the terminal output to locate any version of Openam oauth2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 15.0.4), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.openidentityplatform.openam 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-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Openam oauth2, 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

OpenAM is an open access management solution. In versions 15.0.3 and prior, the `getCustomLoginUrlTemplate` method in RealmOAuth2ProviderSettings.java is vulnerable to template injection due to its usage of user input. Although the developer intended to implement a custom URL for handling login to override the default PingOne Advanced Identity Cloud login page,they did not restrict the `CustomLoginUrlTemplate`, allowing it to be set freely. Commit fcb8432aa77d5b2e147624fe954cb150c568e0b8 introduces `TemplateClassResolver.SAFER_RESOLVER` to disable the resolution of commonly exploited classes in FreeMarker template injection. As of time of publication, this fix is expected to be part of version 15.0.4.
