Descriptions

Cloud Foundry CredHub, versions prior to 2.5.10, connects to a MySQL database without TLS even when configured to use TLS. A malicious user with access to the network between CredHub and its MySQL database may eavesdrop on database connections and thereby gain unauthorized access to CredHub and other components.

Cloud Foundry CredHub, versiones anteriores a 2.5.10, se conecta a una base de datos MySQL sin TLS inclusive cuando está configurado para usar TLS. Un usuario malicioso con acceso a la red entre CredHub y su base de datos MySQL puede espiar las conexiones de la base de datos y, por lo tanto, conseguir acceso no autorizado a CredHub y otros componentes.
