CVE-2017-3599

Estado: ModificadaAlta (7.5)—💥 Exploit

Se ha encontrado una vulnerabilidad en el componente MySQL Server de Oracle MySQL (subcomponente: Server: Pluggable Auth). Las versiones compatibles que se ven afectadas son versión 5.6.35 y anteriores y versión 5.7.17 y anteriores. La vulnerabilidad fácilmente "explotable" permite que un atacante no autenticado 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 una capacidad no autorizada para generar una suspensión o un bloqueo repetible con frecuencia (DoS completo) de MySQL Server.

CVSS 3.0 Base Score 7.5 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). NOTE: the previous information is from the April 2017 CPU. 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 es un desbordamiento de enteros en sql/auth/sql_authentication.cc que permite a los atacantes remotos generar una Denegación de Servicio (DoS) por medio de un paquete de autenticación creado.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
