CVE-2014-7807: Apache CloudStack unauthenticated LDAP binds

CVSS:
7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P

Vendors:
The Apache Software Foundation
Citrix, Inc.

Versions Afffected:
Apache CloudStack 4.3, 4.4

Description:
Apache CloudStack may be configured to authenticate LDAP users. When so configured, it performs a simple LDAP bind with the name and password provided by a user. Simple LDAP binds are defined with three mechanisms (RFC 4513): 1) username and password; 2) unauthenticated if only a username is specified; and 3) anonymous if neither username or password is specified. Currently, Apache CloudStack does not check if the password was provided which could allow an attacker to bind as an unauthenticated user.

Mitigation:
Users of Apache CloudStack 4.4 and derivatives should update to the latest version (4.4.2)

An updated release for Apache CloudStack 4.3.2 is in testing. Until that is released, we recommend following the mitigation below:

By default, many LDAP servers are not configured to allow unauthenticated binds. If the LDAP server in use allow this behaviour, a potential interim solution would be to consider disabling unauthenticated binds.

As mentioned previously, the realhostip.com dynamic DNS resolver service is being retired this summer. During testing of Apache CloudStack version 4.3, we found a few more issues related to realhostip.com that have been addressed for the 4.4 release.

In order to give everybody a reasonable window to update their CloudStack installations to use the updated code, the retirement date for the realhostip.com service has been pushed back to September 30th, 2014. This provides an additional 3 months from the original June 30th date.

Any questions related to the retirement of the realhostip.com service and it's affect on CloudStack installations should be send to the CloudStack Users or Development mailing lists. Further information about how to subscribe and interact with the mailing lists is available at https://cloudstack.apache.org/mailing-lists.html.

Update: The email infrastructure is back to normal, although it may take some time for the queued messages to completely flush out of the backlog. See the linked post from the ASF infrastructure team below for more details.

There are ongoing problems with the ASF's email infrastructure that mean no mail delivery is happening for our project's lists. Please check the official ASF infrastructure blog post and twitter feed for updates.

Earlier this week, a security vulnerability was disclosed in OpenSSL, one of the software libraries that Apache CloudStack uses to encrypt data sent over network connections. As the vulnerability has existed in OpenSSL since early 2012, System VMs in Apache CloudStack versions 4.1.1-4.3 are running software using vulnerable versions of OpenSSL. This includes CloudStack's Virtual Router VMs, Console Proxy VMs, and Secondary Storage VMs.

We are actively working on creating updated System VM templates for each recent version of Apache CloudStack, and for each of the hypervisor platforms which Apache CloudStack supports. Due to our testing and QA processes, this will take several days. In the meantime, we want to provide our users with a temporary workaround for currently running System VMs.

If you are running Apache CloudStack 4.0.0-incubating through the recent 4.3 release, the following steps will help ensure the security of your cloud infrastructure until an updated version of the System VM template is available:

For KVM/Xen hosted systems

1. As an administrator in the CloudStack web UI, navigate to Infrastructure->System VMs
2. For each System VM listed, note the host it is running on, and it’s “Link Local IP address."
3. With that data, perform the following steps for each System VM:
   1. ssh into that host as root
   2. From the host, ssh into the SSVM via it’s link local IP address: (e.g. ssh -i /root/.ssh/id_rsa.cloud -p 3922 169.254.3.33)
   3. On the System VM, first run "apt-get update"
   4. Then run apt-get install "openssl libssl1.0.0". If a dialog appears asking to restart programs, accept it’s request.
   5. Next, for Secondary Storage VMs, run /etc/init.d/apache2 restart
   6. Log out of the System VM and host server
4. Back in the CloudStack UI, now navigate to Infrastructure->Virtual Routers. For each VR, host it's running on and it's link local IP address, and then repeat steps a-f above.

For VMWare hosted systems

1. As an administrator in the CloudStack web UI, navigate to Infrastructure->System VMs
2. For each System VM listed, note it's management IP address
3. With that data, perform the following steps for each System VM:
4. From the Management Server, ssh to the System VM via it's management IP: (eg ssh -i /var/lib/cloud/management/.ssh/id_rsa -p 3922 root@10.40.50.8)
5. On the System VM, first run "apt-get update"
6. Then run apt-get install "openssl libssl1.0.0". If a dialog appears asking to restart programs, accept it’s request.
7. Next, for Secondary Storage VMs, run /etc/init.d/apache2 restart
8. Log out of the System VM
9. Back in the CloudStack UI, now navigate to Infrastructure->Virtual Routers. For each VR, host it's running on and it's link local IP address, and then repeat steps a-f above.

Verification

On each System VM, you can test if it has non-vulnerable openssl packages installed by listing installed packages and looking at the installed versions of openssl and libssl. As in the example below, for a system to be non-vulnerable, the packages need to be at or above version 1.0.1e-2+deb7u6:

root@v-14-VM:~# dpkg -l|grep ssl ii  libssl1.0.0:i386                     1.0.1e-2+deb7u6                  i386         SSL shared libraries ii  openssl                              1.0.1e-2+deb7u6                  i386         Secure Socket Layer (SSL) binary and related cryptographic tools

We realize that for larger installations where System VMs are being actively created and destroyed based on customer demand, this is a very rough stop-gap. The Apache CloudStack security team is actively working on a more permanent fix and will be releasing that to the community as soon as possible.

For Apache CloudStack installations that secure the web-based user-interface with SSL, these may also be vulnerable to HeartBleed, but that is outside the scope of this blog post. We recommend testing your installation with [1] to determine if you need to patch/upgrade the SSL library used by any web servers (or other SSL-based services) you use.

Flexible, scalable, Open Source Infrastructure as a Service (IaaS) used by organizations such as Zynga, Datapipe, and ISWest, among others, for creating, managing, and deploying public, private, and hybrid Cloud Computing environments

Forest Hill, MD --25 March 2014-- The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 170 Open Source projects and initiatives, today announced Apache CloudStack v4.3, the latest feature release of the CloudStack cloud orchestration platform.

Apache CloudStack is an integrated Infrastructure-as-a-Service (IaaS) software platform that allows users to build feature-rich public, private, and hybrid cloud environments. CloudStack includes an intuitive user interface and rich APIs for managing the compute, networking, software, and storage infrastructure resources.

Recently the Apache CloudStack PMC was informed that the realhostip.com Dynamic DNS service that CloudStack currently uses as part of the console proxy will be disbanded this summer. The realhostip service will be shut down June 30th, 2014, meaning users have approximately 3 months to mitigate this.

Prior to version 4.3, CloudStack used the realhostip.com service by default. With the release of CloudStack version 4.3 the default communication method with the console proxy is plaintext HTTP.

Who is Affected

CloudStack installations prior to version 4.3 that have not been reconfigured to use a DNS domain other than realhostip.com for Console Proxy or Secondary Storage must make changes to continue functioning past June 30th, 2014.

Steps You Need to Take

If you meet the criteria above, there are several options to prepare for realhostip retirement:

• Set up wildcard SSL certificate and DNS entries: This method is already well supported within prior versions of CloudStack.
• Upgrade to CloudStack 4.3 and disable SSL: This is only recommended for development installations, or private clouds that contain no information of importance.
• Upgrade to CloudStack 4.3, set up static SSL certificate and configure load balancer to point to the correct IP address: While this allows an administrator to skip setting up the DNS entries from the previous option, it is a more advanced option as CloudStack 4.3 does not support automatic load balancer configuration for the Console Proxy. It is hoped this functionality will be available in future releases.

For instructions on how to set up SSL encryption for use with CloudStack console proxy, please read the console proxy section of the CloudStack administration guide.

Additionally, if you will be using an SSL vendor who requires an intermediate CA chain to be installed for proper SSL validation by web browsers, detailed instructions for configuring the intermediate CA chain in CloudStack can be found here.

The Apache CloudStack security team does not recommend running a production cloud with either the realhostip.com SSL certificate, or with no SSL encryption at all.
