How to Fix CVE-2024-5967

To remediate this vulnerability, upgrade all affected Keycloak ldap federation 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.keycloak:keycloak-ldap-federation fixed: 25.0.1 
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-ldap-federation</artifactId>
    <version>25.0.1</version>
</dependency>
org.keycloak:keycloak-ldap-federation fixed: 22.0.12 
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-ldap-federation</artifactId>
    <version>22.0.12</version>
</dependency>
org.keycloak:keycloak-ldap-federation fixed: 24.0.6 
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-ldap-federation</artifactId>
    <version>24.0.6</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.keycloak

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-5967, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.keycloak

Analyze the terminal output to locate any version of Keycloak ldap federation in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 25.0.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.keycloak 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-276: Incorrect Default Permissions, where during installation, installed file permissions are set to allow anyone to modify those files. In Keycloak ldap federation, 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

### Impact The LDAP testing endpoint allows to change the Connection URL independently of and without having to re-enter the currently configured LDAP bind credentials. An attacker with admin access (permission manage-realm) can change the LDAP host URL ("Connection URL") to a machine they control. The Keycloak server will connect to the attacker's host and try to authenticate with the configured credentials, thus leaking them to the attacker. As a consequence, an attacker who has compromised the admin console/compromised a user with sufficient privileges can leak domain credentials and can now attack the domain. ### Acknowledgements Special thanks to Simon Wessling for reporting this issue and helping us improve our project
