Descriptions

An issue was discovered in OpenLDAP 2.x before 2.4.48. When using SASL authentication and session encryption, and relying on the SASL security layers in slapd access controls, it is possible to obtain access that would otherwise be denied via a simple bind for any identity covered in those ACLs. After the first SASL bind is completed, the sasl_ssf value is retained for all new non-SASL connections. Depending on the ACL configuration, this can affect different types of operations (searches, modifications, etc.). In other words, a successful authorization step completed by one user affects the authorization requirement for a different user.

Se detectó un problema en OpenLDAP versiones 2.x anteriores a 2.4.48. Cuando se utiliza la autenticación SASL y el cifrado de sesión y confiando en las capas de seguridad SASL en los controles de acceso slapd, es posible obtener acceso que, de lo contrario, se denegaría por medio de un enlace simple para cualquier identidad cubierta en esas ACL. Una vez completado el primer enlace SASL, se conserva el valor sasl_ssf para todas las nuevas conexiones que no sean SASL. Dependiendo de la configuración de ACL, esto puede afectar a diferentes tipos de operaciones (búsquedas, modificaciones, etc.). En otras palabras, un paso de autorización completado con éxito por un usuario afecta al requisito de autorización para un usuario diferente.
