Summary

The i_create_images_and_backing (aka create_images_and_backing) method in libvirt driver in OpenStack Compute (Nova) Grizzly, Havana, and Icehouse, when using KVM live block migration, does not properly create all expected files, which allows attackers to obtain snapshot root disk contents of other users via ephemeral storage.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

up its sudo configuration. If a different flaw was found in OpenStack
Nova, this vulnerability could be used to escalate privileges. This
issue only affected Ubuntu 13.10 and Ubuntu 14.04 LTS. (CVE-2013-1068)

Bernhard M. Wiedemann and Pedraig Brady discovered that OpenStack Nova
did not properly verify the virtual size of a QCOW2 images. A remote
authenticated attacker could exploit this to create a denial of
service via disk consumption. This issue did not affect Ubuntu 14.04
LTS. (CVE-2013-4463, CVE-2013-4469)

JuanFra Rodriguez Cardoso discovered that OpenStack Nova did not
enforce SSL connections when Nova was configured to use QPid and
qpid_protocol is set to 'ssl'. If a remote attacker were able to
perform a man-in-the-middle attack, this flaw could be exploited to
view sensitive information. Ubuntu does not use QPid with Nova by
default. This issue did not affect Ubuntu 14.04 LTS. (CVE-2013-6491)

Loganathan Parthipan discovered that OpenStack Nova did not properly
create expected files during KVM live block migration. A remote
authenticated attacker could exploit this to obtain root disk snapshot
contents via ephemeral storage. This issue did not affect Ubuntu 14.04
LTS. (CVE-2013-7130)

Stanislaw Pitucha discovered that OpenStack Nova did not enforce the
image format when rescuing an instance. A remote authenticated
attacker could exploit this to read host files. In the default
installation, attackers would be isolated by the libvirt guest
AppArmor profile. This issue only affected Ubuntu 13.10.
(CVE-2014-0134)

Mark Heckmann discovered that OpenStack Nova did not enforce RBAC
policy when adding security group rules via the EC2 API. A remote
authenticated user could exploit this to gain unintended access to
this API. This issue only affected Ubuntu 13.10. (CVE-2014-0167).
