VMware vCenter Server Appliance (vCSA) 5.5 before Update 2, 5.1 before Update 3, and 5.0 before Update 3c does not properly validate certificates when connecting to a CIM Server on an ESXi host, which allows man-in-the-middle attackers to spoof CIM servers via a crafted certificate.

The VMware vCenter Server installed on the remote host is version 5.0 prior to Update 3c, 5.1 prior to Update 3, or 5.5 prior to Update 2.
It is, therefore, affected by multiple vulnerabilities in third party libraries :

  - Due to improper certificate validation when connecting     to a CIM server on an ESXi host, an attacker can     perform man-in-the-middle attacks. (CVE-2014-8371)

  - The bundled version of Oracle JRE is prior to 1.6.0_81     and thus is affected by multiple vulnerabilities. Note     that this only affects version 5.1 and 5.0 of vCenter     but is only fixed in 5.1 Update 3.

a. VMware vCSA cross-site scripting vulnerability

   VMware vCenter Server Appliance (vCSA) contains a vulnerability    that may allow for Cross Site Scripting. Exploitation of this    vulnerability in vCenter Server requires tricking a user to click    on a malicious link or to open a malicious web page.
