Descriptions

OpenStack Keystone through 14.0.1 has a user enumeration vulnerability because invalid usernames have much faster responses than valid ones for a POST /v3/auth/tokens request. NOTE: the vendor's position is that this is a hardening opportunity, and not necessarily an issue that should have an OpenStack Security Advisory

** EN DISPUTA ** OpenStack Keystone hasta la versión 14.0.1 tiene una vulnerabilidad de enumeración de usuarios debido a que los nombres de usuario inválidos tienen respuestas mucho más rápidas que los válidos en una petición POST en /v3/auth/tokens. NOTA: el fabricante siente que las ventajas de cambiar esto serían demasiado escasas en relación con la degradación del rendimiento.
