Issue date:  2013-04-25

1. Summary

   VMware has updated vCenter Server Appliance (vCSA) and vCenter 
   Server running on Windows to address multiple security 
   vulnerabilities.  

2. Relevant releases

   vCenter Server 5.1 without Update 1

3. Problem Description

   a. vCenter Server AD anonymous LDAP binding credential by-pass


      vCenter Server when deployed in an environment that uses 
      Active Directory (AD) with anonymous LDAP binding enabled
      doesn't properly handle login credentials. In this
      environment, authenticating to vCenter Server with a valid
      user name and a blank password may be successful even if 
      a non-blank password is required for the account. 

      The issue is present on vCenter Server 5.1, 5.1a and 5.1b
      if AD anonymous LDAP binding is enabled. The issue is 
      addressed in vCenter Server 5.1 Update 1 by removing the
      possibility to authenticate using blank passwords. This
      change in the authentication mechanism is present 
      regardless if anonymous binding is enabled or not.

      Workaround
      The workaround is to discontinue the use of AD anonymous
      LDAP binding if it is enabled in your environment. AD 
      anonymous LDAP binding is not enabled by default. The TechNet
      article listed in the references section explains how to 
      check for anonymous binding (look for "anonymous binding"
      in the article: anonymous binding is enabled if the seventh
      bit of the dsHeuristics attribute is set to 2)


      The Common Vulnerabilities and Exposures project (cve.mitre.org) has 
      assigned the name CVE-2013-3107 to this issue. 

      Column 4 of the following table lists the action required to
      remediate the vulnerability in each release, if a solution is
      available. 


        VMware		Product	Running	Replace with/
        Product		Version	on	Apply Patch
        =============	=======	=======	=================
        vCenter Server	5.1	Any	5.1 Update 1
        vCenter Server	5.0	Any	not applicable
	vCenter	Server	4.1	Windows	not applicable
	vCenter	Server	4.0	Windows	not applicable
	VirtualCenter	2.5	Windows	not applicable
	

   b. vCenter Server Appliance arbitrary file execution


      The vCenter Server Appliance (vCSA) contains a remote code 
      vulnerability. An authenticated attacker with access to the 
      Virtual Appliance Management Interface (VAMI) may run 
      an existing file as root. In the default vCSA setup, 
      authentication to vCSA is limited to root since root 
      is the only defined user.

      The Common Vulnerabilities and Exposures project (cve.mitre.org) has 
      assigned the name CVE-2013-3079 to this issue. 

      Column 4 of the following table lists the action required to
      remediate the vulnerability in each release, if a solution is
      available. 


        VMware		Product	Running	Replace with/
        Product		Version	on	Apply Patch
        =============	=======	=======	=================
        vCSA 		5.1	Linux 	5.1 Update 1
	vCSA 		5.0 	Linux 	not affected

   c. vCenter Server Appliance arbitrary file upload

      The vCenter Server Appliance (vCSA) VAMI web interface 
      contains a vulnerability that allows an authenticated remote
      attacker to upload files to an arbitrary location creating new
      files or overwriting existing files. Replacing certain files
      may result in a denial of service condition or code execution.
      In the default vCSA setup, authentication to vCSA is limited to
      root since root is the only defined user.


      The Common Vulnerabilities and Exposures project (cve.mitre.org) has 
      assigned the name CVE-2013-3080 to this issue. 

      Column 4 of the following table lists the action required to
      remediate the vulnerability in each release, if a solution is
      available. 


        VMware		Product	Running	Replace with/
        Product		Version	on	Apply Patch
        =============	=======	=======	=================
        vCSA 		5.1	Linux 	5.1 Update 1
	vCSA 		5.0 	Linux 	not affected


   d. vCenter, Update Manager, Oracle (Sun) JRE update 1.6.0_37
      
      Oracle (Sun) JRE is updated to version 1.6.0_37, which addresses
      multiple security issues that existed in earlier releases of
      Oracle (Sun) JRE. 

      Oracle has documented the CVE identifiers that are addressed
      in JRE 1.6.0_37 in the Oracle Java SE Critical Patch Update
      Advisory of October 2012. The References section provides a
      link to this advisory. 

      Column 4 of the following table lists the action required to 
      remediate the vulnerability in each release, if a solution is
      available. 

        VMware		Product	Running	Replace with/
        Product		Version	on	Apply Patch

   e. vCenter Server tc-server 2.8.1 / Apache Tomcat 6.0.36 update

      tc-server has been updated to version 2.8.1 to address multiple
      security issues. This version of tc-server includes Apache 
      Tomcat 6.0.36 

      The Common Vulnerabilities and Exposures project (cve.mitre.org) 
      has assigned the names CVE-2012-5885, CVE-2012-5886, CVE-2012-5887,
      CVE-2012-2733, CVE-2012-4534, CVE-2012-3546 and CVE-2012-4431
