CVE-2020-5399

Estado: ModificadaAlta (7.4)—

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.
