CVE-2024-5967

Acknowledgements

Special thanks to Simon Wessling for reporting this issue and helping us improve our project

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.

CVE-2024-5967 has a CVSS score of 2.7 (Low). The vector is network-reachable, high privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (25.0.1, 22.0.12, 24.0.6); upgrading removes the vulnerable code path.

1. What is CVE-2024-5967? CVE-2024-5967 is a low-severity security vulnerability in org.keycloak:keycloak-ldap-federation (maven), affecting versions = 25.0.0. It is fixed in 25.0.1, 22.0.12, 24.0.6.
2. How severe is CVE-2024-5967? CVE-2024-5967 has a CVSS score of 2.7 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of org.keycloak:keycloak-ldap-federation are affected by CVE-2024-5967? org.keycloak:keycloak-ldap-federation (maven) versions = 25.0.0 is affected.
4. Is there a fix for CVE-2024-5967? Yes. CVE-2024-5967 is fixed in 25.0.1, 22.0.12, 24.0.6. Upgrade to this version or later.
5. Is CVE-2024-5967 exploitable, and should I be worried? Whether CVE-2024-5967 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2024-5967 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2024-5967?
   • Upgrade org.keycloak:keycloak-ldap-federation to 25.0.1 or later
   • Upgrade org.keycloak:keycloak-ldap-federation to 22.0.12 or later
   • Upgrade org.keycloak:keycloak-ldap-federation to 24.0.6 or later
