Descriptions

The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7 does not properly restrict the use of TGT credentials for armoring TGS requests, which might allow remote authenticated users to impersonate a client by rewriting an inner request, aka a "KrbFastReq forgery issue."

El Centro de distribución de claves (KDC) en MIT Kerberos 5 (también conocido como krb5) v1.7 no restringe correctamente el uso de credenciales TGT para proteger solicitudes TGS, lo que podría permitir a usuarios remotos autenticados suplantar a un cliente mediante la reescritura de una solicitud interior, también conocido como " falsificación KrbFastReq"
