Multiple WSO2 products have been identified as vulnerable to perform user impersonatoin using JIT provisioning. In order for this vulnerability to have any impact on your deployment, following conditions must be met: * An IDP configured for federated authentication and JIT provisioning enabled with the "Prompt for username, password and consent" option. * A service provider that uses the above IDP for federated authentication and has the "Assert identity using mapped local subject identifier" flag enabled. Attacker should have: * A fresh valid user account in the federated IDP that has not been used earlier. * Knowledge of the username of a valid user in the local IDP. When all preconditions are met, a malicious actor could use JIT provisioning flow to perform user impersonation.

Summary
  • (es) Se han identificado varios productos WSO2 como vulnerables para realizar suplantaciones de usuarios mediante el aprovisionamiento JIT. Para que esta vulnerabilidad tenga algún impacto en su implementación, se deben cumplir las siguientes condiciones: * Un IDP configurado para autenticación federada y aprovisionamiento JIT habilitado con la opción "Solicitar nombre de usuario, contraseña y consentimiento". * Un proveedor de servicios que utiliza el IDP anterior para la autenticación federada y tiene habilitada la opción "Afirmar identidad utilizando un identificador de sujeto local asignado". El atacante debe tener: * Una cuenta de usuario nueva y válida en el IDP federado que no se haya utilizado anteriormente. * Conocimiento del nombre de usuario de un usuario válido en el IDP local. Cuando se cumplen todas las condiciones previas, un actor malintencionado podría utilizar el flujo de aprovisionamiento JIT para realizar la suplantación de usuario.
