Descriptions

When SAML authentication is enabled, Juniper Networks Mist Cloud UI might incorrectly handle child elements in SAML responses, allowing a remote attacker to modify a valid SAML response without invalidating its cryptographic signature to bypass SAML authentication security controls. This issue affects all Juniper Networks Mist Cloud UI versions prior to September 2 2020.

Cuando la autenticación SAML está habilitada, Juniper Networks Mist Cloud UI puede manejar incorrectamente los elementos secundarios en las respuestas de SAML, permitiendo a un atacante remoto modificar una respuesta SAML válida sin invalidar su firma criptográfica para omitir los controles de seguridad de autenticación SAML. Este problema afecta a todas las versiones de Juniper Networks Mist Cloud UI anteriores al 2 de septiembre de 2020
