Descriptions

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: C API). Supported versions that are affected are 5.5.55 and earlier and 5.6.35 and earlier. Difficult to exploit vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all MySQL Server accessible data. 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). NOTE: the previous information is from the April 2017 CPU. Oracle has not commented on third-party claims that this issue allows man-in-the-middle attackers to hijack the authentication of users by leveraging incorrect ordering of security parameter verification in a client, aka, "The Riddle".

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".

It was discovered that the MySQL client command line tools only checked after authentication whether server supported SSL. A man-in-the-middle attacker could use this flaw to hijack client's authentication to the server even if the client was configured to require SSL connection.
