CVE-2018-2645

Estado: ModificadaMedia (4.9)—

Vulnerabilidad en el componente MySQL Server en Oracle MySQL (subcomponente: Server: Performance Schema). Las versiones compatibles que se han visto afectadas son la 5.6.38 y anteriores, y la 5.7.20 y anteriores. Una vulnerabilidad fácilmente explotable permite que un atacante con un alto nivel de privilegios que tenga acceso a red por medio de múltiples protocolos comprometa la seguridad de MySQL Server. Los ataques exitosos a esta vulnerabilidad pueden resultar en un acceso no autorizado a datos críticos o un acceso completo a todos los datos accesibles de MySQL Server. CVSS 3.0 Base Score 4.9 (impactos en la confidencialidad). Vector CVSS: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N).
