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.
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.
