CVE-2023-6717
Full vulnerability record from the local CVENow database.
Description
A flaw was found in the SAML client registration in Keycloak that could allow an administrator to register malicious JavaScript URIs as Assertion Consumer Service POST Binding URLs (ACS), posing a Cross-Site Scripting (XSS) risk. This issue may allow a malicious admin in one realm or a client with registration access to target users in different realms or applications, executing arbitrary JavaScript in their contexts upon form submission. This can enable unauthorized access and harmful actions, compromising the confidentiality, integrity, and availability of the complete KC instance.

"value": "Se encontró una falla en el registro del cliente SAML en Keycloak que podría permitir a un administrador registrar URI de JavaScript maliciosos como URL de enlace POST (ACS) del servicio de consumidor de aserción, lo que plantea un riesgo de Cross-Site Scripting (XSS). Este problema puede permitir que un administrador malicioso en un dominio o un cliente con acceso de registro se dirija a usuarios en diferentes dominios o aplicaciones, ejecutando JavaScript arbitrario en sus contextos al enviar el formulario. Esto puede permitir acceso no autorizado y acciones dañinas, comprometiendo la confidencialidad, integridad y disponibilidad de la instancia de KC completa."
