CVE-2018-7958

Estado: ModificadaAlta (7.4)—

There is an anonymous TLS cipher suites supported vulnerability in Huawei eSpace product. An unauthenticated, remote attacker launches man-in-the-middle attack to hijack the connection from a client when the user signs up to log in by TLS. Due to insufficient authentication, which may be exploited to intercept and tamper with the data information.
