CVE-2017-3305

Estado: ModificadaMedia (5.3)—

Se ha descubierto una vulnerabilidad en el componente MySQL Server de Oracle MySQL (subcomponente: Servidor: C API). Las versiones compatibles que se ven afectadas son versión 5.5.55 y anteriores y versión 5.6.35 y anteriores. Una vulnerabilidad difícil de explotar permite que un atacante con pocos privilegios con acceso a la red por medio de múltiples protocolos ponga en peligro el servidor MySQL. Los ataques con éxito de esta vulnerabilidad pueden resultar en un acceso no autorizado a información crítica o acceso completo a todos los datos disponibles del Servidor MySQL.

CVSS 3.0 Base Score 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N). NOTA: la información anterior es de la CPU de abril de 2017. Oracle no ha comentado sobre las afirmaciones de terceros de que este problema permite a los atacantes de tipo man-in-the-middle secuestrar la autenticación de los usuarios aprovechando el pedido incorrecto de la comprobación de los parámetros de seguridad en un cliente, también conocido como "The Riddle".
