VMware vSphere ESXi (6.7 prior to ESXi670-201810101-SG, 6.5 prior to ESXi650-201811102-SG, and 6.0 prior to ESXi600-201807103-SG) and VMware vCenter Server (6.7 prior to 6.7 U1b, 6.5 prior to 6.5 U2b, and 6.0 prior to 6.0 U3j) contain an information disclosure vulnerability in clients arising from insufficient session expiration. An attacker with physical access or an ability to mimic a websocket connection to a user’s browser may be able to obtain control of a VM Console after the user has logged out or their session has timed out.

CRLF injection vulnerability in VMware vCenter Server 6.0 before U2 and ESXi 6.0 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.

Cross-site scripting (XSS) vulnerability in the Web Client in VMware vCenter Server 5.1 before update 3d, 5.5 before update 3d, and 6.0 before update 2 on Windows allows remote attackers to inject arbitrary web script or HTML via the flashvars parameter.

VMware vCenter Server 5.5 before u3 and 6.0 before u1 does not verify X.509 certificates from TLS LDAP servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
