CVE-2018-3123

Estado: ModificadaMedia (5.9)—

Vulnerabilidad en el componente MySQL Server en Oracle MySQL (subcomponente: Server: libmysqld). Las versiones compatibles que se han visto afectadas son la 5.6.42 y anteriores, la 5.7.24 y anteriores y la 8.0.13 y anteriores. Una vulnerabilidad difícilmente explotable permite que un atacante no autenticado que tenga acceso a red por medio de múltiples protocolos comprometa el servidor MySQL. Los ataques exitosos de esta vulnerabilidad pueden resultar en acceso no autorizado a datos críticos o acceso completo a todos los datos accesibles del servidor MySQL. CVSS 3.0 Base Score 5.9 (impactos de confidencialidad). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).
