How to Fix CVE-2021-27582

To remediate this vulnerability, upgrade all affected Openid connect parent 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.mitre:openid-connect-parent fixed: Latest secure release 
<dependency>
    <groupId>org.mitre</groupId>
    <artifactId>openid-connect-parent</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=org.mitre

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2021-27582, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.mitre

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

Note: The mvn dependency:tree -Dincludes=org.mitre 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-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), where the product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype. In Openid connect parent, 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

org/mitre/oauth2/web/OAuthConfirmationController.java in the OpenID Connect server implementation for MITREid Connect through 1.3.3 contains a Mass Assignment (aka Autobinding) vulnerability. This arises due to unsafe usage of the @ModelAttribute annotation during the OAuth authorization flow, in which HTTP request parameters affect an authorizationRequest.
