   VMware vCenter Server directory traversal and information disclosure
   vulnerabilities. vSphere Client Installer is delivered through an
   unsigned package.

3. Problem Description

  a. vCenter Server Directory Traversal vulnerability

    A directory traversal vulnerability allows an attacker to remotely
    retrieve files from vCenter Server without authentication. In order
    to exploit this vulnerability, the attacker will need to have access
    to the network on which the vCenter Server host resides.

    In case vCenter Server is installed on Windows 2008 or
    Windows 2008 R2, the security vulnerability is not present.

    The Common Vulnerabilities and Exposures project (cve.mitre.org) has
    assigned the name CVE-2011-0426 to this issue.

    VMware         Product   Running  Replace with/
    Product        Version   on       Apply Patch
    =============  ========  =======  =================
    vCenter        4.1       Windows  Update 1 *
    vCenter        4.0       Windows  Update 3 *
    VirtualCenter  2.5       Windows  Update 6a

    hosted **      any       any      not affected

    ESXi           any       ESXi     not affected

    ESX            any       ESX      not affected

   * vCenter 4.1 and vCenter 4.0 installed on Windows 2008 or Windows
     2008 R2 is not affected
  ** hosted products are VMware Workstation, Player, ACE, Fusion.

  b. vCenter Server SOAP ID disclosure

    The SOAP session ID can be retrieved by any user that is logged in
    to vCenter Server. This might allow a local unprivileged user on
    vCenter Server to elevate his or her privileges.

    VMware would like to thank Claudio Criscione for reporting this
    issue to us.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CVE-2011-1788 to this issue.

    VMware         Product   Running  Replace with/
    Product        Version   on       Apply Patch
    =============  ========  =======  =================
    vCenter        4.1       Windows  Update 1
    vCenter        4.0       Windows  Update 3
    VirtualCenter  2.5       Windows  not affected

    hosted *       any       any      not affected

    ESXi           any       ESXi     not affected

    ESX            any       ESX      not affected

  * hosted products are VMware Workstation, Player, ACE, Fusion.

  c. vSphere Client Installer package not digitally signed

    The digitally signed vSphere Client installer is packaged in a
    self-extracting installer package which is not digitally signed. As
    a result, when you run the install package file to extract and start
    installing, the vSphere Client installer may display a Windows
    warning message stating that the publisher of the install package
    cannot be verified.
 
    The vSphere Client Installer package of the following product
    versions is now digitally signed:

      vCenter Server 4.1 Update 1
      vCenter Server 4.0 Update 3

      ESXi 4.1 Update 1
      ESXi 4.0 with patch ESXi400-201103402-SG

      ESX 4.1 Update 1
      ESX 4.0 with patch ESX400-201103401-SG

    An install or update of the vSphere Client from these releases will
    not present a security warning from Windows.
    Note: typically the vSphere Client will request an update if the
    existing client is pointed at a newer version of vCenter or ESX.

    VMware Knowledge Base article 1021404 explains how the unsigned
    install package can be obtained in an alternative, secure way for an
    environment with VirtualCenter 2.5, ESXi/ESX 3.5 or ESX 3.0.3.

    VMware would like to thank Claudio Criscione for reporting this
    issue to us.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CVE-2011-1789 to this issue.
