The VMware vCenter Server installed on the remote host is version 5.5 prior to 5.5u3. It is, therefore, affected by a man-in-the-middle spoofing vulnerability due to improper validation of X.509 certificates from TLS LDAP servers. A remote, man-in-the-middle attacker can exploit this to intercept network traffic by spoofing a TLS server via a crafted certificate, resulting in the manipulation or disclosure of sensitive information.
