Citrix CloudPlatform Multiple Security Updates
Document ID: CTX135815
Created On: 24/04/2013
Updated On: 24/04/2013
Severity: Critical
Description of Problem
A number of security vulnerabilities have been identified in Citrix
CloudPlatform, formerly known as CloudStack. These vulnerabilities have been
assigned the following CVE numbers:
- - CVE-2013-2756: Console proxy authentication bypass vulnerability
- - CVE-2013-2757: Unauthenticated VNC ports available on the management network
- - CVE-2013-2758: Console proxy URLs may contain sensitive information
These vulnerabilities affect all versions of CloudPlatform 3.0.x up to and
including 3.0.6 with patch B applied when deployed with XenServer, other Xen
hypervisors or KVM.
What Customers Should Do
A security patch has been released to address these issues. Citrix strongly
recommends that all affected customers upgrade to version 3.0.6 of Citrix
CloudPlatform and apply this patch. This patch can be downloaded from the
following locations:
Citrix CloudPlatform:
RedHat Enterprise Linux 5: CTX137279 CloudPlatform 3.0.6 PatchC - RHEL 5
RedHat Enterprise Linux 6.2: CTX137280 CloudPlatform 3.0.6 PatchC - RHEL 6.2
RedHat Enterprise Linux 6.3: CTX137281 CloudPlatform 3.0.6 PatchC (RHEL 6.3)
Customers using Citrix CloudStack 2.2.x, or CloudPlatform 3.0.x that cannot
upgrade to 3.0.6, should contact their Citrix Customer Support representative
for further information. Customers upgrading from affected versions of
CloudPlatform should ensure that all hypervisors are appropriately configured
for the new version of CloudPlatform.
Citrix also recommends that customers consider making the following changes
to their CloudPlatform deployments:
- - Customers should avoid the use of realhostip.com SSL certificates for
production environments. Please see Citrix Knowledge Center article
CTX133468 How to Replace realhostip.com with Your Own Domain Name for further
information on how to configure your CloudPlatform deployment.
- - In line with best practice, customers should ensure that the CloudPlatform
management network is segregated from all other traffic.
