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
vCenter Server 5.0 without Update 3

Update Manager 5.0 without Update 3
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.

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.

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.
