"value": "JumpServer is an open source bastion host. As an unauthenticated user, it is possible to authenticate to the core API with a username and an SSH public key without needing a password or the corresponding SSH private key. An SSH public key should be considered public knowledge and should not used as an authentication secret alone. JumpServer provides an API for the KoKo component to validate user private key logins. This API does not verify the source of requests and will generate a personal authentication token. Given that public keys can be easily leaked, an attacker can exploit the leaked public key and username to authenticate, subsequently gaining access to the current user's information and authorized actions. This issue has been addressed in versions 2.28.20 and 3.7.1. Users are advised to upgrade. There are no known workarounds for this vulnerability."

"value": "JumpServer es un host de bastionado de c\u00f3digo abierto. Como usuario no autenticado, es posible autenticarse en la API principal con un nombre de usuario y una clave p\u00fablica SSH sin necesidad de una contrase\u00f1a o la clave privada SSH correspondiente. Una clave p\u00fablica SSH debe considerarse de conocimiento p\u00fablico y no debe utilizarse \u00fanicamente como secreto de autenticaci\u00f3n. JumpServer proporciona una API para que el componente KoKo valide los inicios de sesi\u00f3n con clave privada del usuario. Esta API no verifica el origen de las solicitudes y generar\u00e1 un token de autenticaci\u00f3n personal. Dado que las claves p\u00fablicas se pueden filtrar f\u00e1cilmente, un atacante puede explotar la clave p\u00fablica y el nombre de usuario filtrados para autenticarse, obteniendo posteriormente acceso a la informaci\u00f3n del usuario actual y a las acciones autorizadas. Este problema se solucion\u00f3 en las versiones 2.28.20 y 3.7.1. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad."
