CVE-2024-40767 6.5 MEDIUM EPSS 0.01

In OpenStack Nova before 27.4.1, 28 before 28.2.1, and 29 before 29.1.1, by supplying a raw format image that is actually a crafted QCOW2 image with a backing file path or VMDK flat image with a descriptor file path, an authenticated user may convince systems to return a copy of the referenced file's contents from the server, resulting in unauthorized access to potentially sensitive data. All Nova deployments are affected. NOTE: this issue exists because of an incomplete fix for CVE-2022-47951 and CVE-2024-32498.

CWE-552 Jul 24, 2024

CVE-2024-32498 6.5 MEDIUM EPSS 0.00

An issue was discovered in OpenStack Cinder through 24.0.0, Glance before 28.0.2, and Nova before 29.0.3. Arbitrary file access can occur via custom QCOW2 external data. By supplying a crafted QCOW2 image that references a specific data file path, an authenticated user may convince systems to return a copy of that file's contents from the server, resulting in unauthorized access to potentially sensitive data. All Cinder and Nova deployments are affected; only Glance deployments with image conversion enabled are affected.

CWE-552 Jul 05, 2024

CVE-2022-47951 5.7 MEDIUM EPSS 0.01

An issue was discovered in OpenStack Cinder before 19.1.2, 20.x before 20.0.2, and 21.0.0; Glance before 23.0.1, 24.x before 24.1.1, and 25.0.0; and Nova before 24.1.2, 25.x before 25.0.2, and 26.0.0. By supplying a specially created VMDK flat image that references a specific backing file path, an authenticated user may convince systems to return a copy of that file's contents from the server, resulting in unauthorized access to potentially sensitive data.

CWE-22 Jan 26, 2023

CVE-2022-37394 3.3 LOW EPSS 0.00

An issue was discovered in OpenStack Nova before 23.2.2, 24.x before 24.1.2, and 25.x before 25.0.2. By creating a neutron port with the direct vnic_type, creating an instance bound to that port, and then changing the vnic_type of the bound port to macvtap, an authenticated user may cause the compute service to fail to restart, resulting in a possible denial of service. Only Nova deployments configured with SR-IOV are affected.

CVE-2021-3654 6.1 MEDIUM NUCLEI EPSS 0.87

A vulnerability was found in openstack-nova's console proxy, noVNC. By crafting a malicious URL, noVNC could be made to redirect to any desired URL.

CWE-601 Mar 02, 2022

CVE-2020-17376 8.3 HIGH EPSS 0.00

An issue was discovered in Guest.migrate in virt/libvirt/guest.py in OpenStack Nova before 19.3.1, 20.x before 20.3.1, and 21.0.0. By performing a soft reboot of an instance that has previously undergone live migration, a user may gain access to destination host devices that share the same paths as host devices previously referenced by the virtual machine on the source host. This can include block devices that map to different Cinder volumes at the destination than at the source. Only deployments allowing host-based connections (for instance, root and ephemeral devices) are affected.

CWE-611 Aug 26, 2020

CVE-2015-9543 3.3 LOW EPSS 0.00

An issue was discovered in OpenStack Nova before 18.2.4, 19.x before 19.1.0, and 20.x before 20.1.0. It can leak consoleauth tokens into log files. An attacker with read access to the service's logs may obtain tokens used for console access. All Nova setups using novncproxy are affected. This is related to NovaProxyRequestHandlerBase.new_websocket_client in console/websocketproxy.py.

CWE-200 Feb 19, 2020

CVE-2013-0326 5.5 MEDIUM EPSS 0.00

OpenStack nova base images permissions are world readable

CWE-732 Dec 05, 2019

CVE-2011-4076 5.9 MEDIUM EPSS 0.00

OpenStack Nova before 2012.1 allows someone with access to an EC2_ACCESS_KEY (equivalent to a username) to obtain the EC2_SECRET_KEY (equivalent to a password). Exposing the EC2_ACCESS_KEY via http or tools that allow man-in-the-middle over https could allow an attacker to easily obtain the EC2_SECRET_KEY. An attacker could also presumably brute force values for EC2_ACCESS_KEY.

CWE-200 Nov 26, 2019

CVE-2019-14433 6.5 MEDIUM EPSS 0.01

An issue was discovered in OpenStack Nova before 17.0.12, 18.x before 18.2.2, and 19.x before 19.0.2. If an API request from an authenticated user ends in a fault condition due to an external exception, details of the underlying environment may be leaked in the response, and could include sensitive configuration or other data.

CWE-209 Aug 09, 2019

CVE-2011-3147 8.6 HIGH EPSS 0.00

Versions of nova before 2012.1 could expose hypervisor host files to a guest operating system when processing a maliciously constructed qcow filesystem.

CWE-200 Apr 22, 2019

CVE-2017-18191 7.5 HIGH EPSS 0.02

An issue was discovered in OpenStack Nova 15.x through 15.1.0 and 16.x through 16.1.1. By detaching and reattaching an encrypted volume, an attacker may access the underlying raw volume and corrupt the LUKS header, resulting in a denial of service attack on the compute host. (The same code error also results in data loss, but that is not a vulnerability because the user loses their own data.) All Nova setups supporting encrypted volumes are affected.

CVE-2017-17051 8.6 HIGH EPSS 0.01

An issue was discovered in the default FilterScheduler in OpenStack Nova 16.0.3. By repeatedly rebuilding an instance with new images, an authenticated user may consume untracked resources on a hypervisor host leading to a denial of service, aka doubled resource allocations. This regression was introduced with the fix for OSSA-2017-005 (CVE-2017-16239); however, only Nova stable/pike or later deployments with that fix applied and relying on the default FilterScheduler are affected.

CWE-400 Dec 05, 2017

CVE-2017-16239 6.5 MEDIUM EPSS 0.00

In OpenStack Nova through 14.0.9, 15.x through 15.0.7, and 16.x through 16.0.2, by rebuilding an instance, an authenticated user may be able to circumvent the Filter Scheduler bypassing imposed filters (for example, the ImagePropertiesFilter or the IsolatedHostsFilter). All setups using Nova Filter Scheduler are affected. Because of the regression described in Launchpad Bug #1732947, the preferred fix is a 14.x version after 14.0.10, a 15.x version after 15.0.8, or a 16.x version after 16.0.3.

CVE-2015-2687 4.7 MEDIUM EPSS 0.00

OpenStack Compute (nova) Icehouse, Juno and Havana when live migration fails allows local users to access VM volumes that they would normally not have permissions for.

CWE-284 Aug 09, 2017

CVE-2017-7214 9.8 CRITICAL EPSS 0.01

An issue was discovered in exception_wrapper.py in OpenStack Nova 13.x through 13.1.3, 14.x through 14.0.4, and 15.x through 15.0.1. Legacy notification exception contexts appearing in ERROR level logs may include sensitive information such as account passwords and authorization tokens.

CWE-532 Mar 21, 2017

CVE-2015-5162 7.5 HIGH EPSS 0.04

The image parser in OpenStack Cinder 7.0.2 and 8.0.0 through 8.1.1; Glance before 11.0.1 and 12.0.0; and Nova before 12.0.4 and 13.0.0 does not properly limit qemu-img calls, which might allow attackers to cause a denial of service (memory and disk consumption) via a crafted disk image.

CWE-399 Oct 07, 2016

CVE-2016-2140 5.3 MEDIUM EPSS 0.01

The libvirt driver in OpenStack Compute (Nova) before 2015.1.4 (kilo) and 12.0.x before 12.0.3 (liberty), when using raw storage and use_cow_images is set to false, allows remote authenticated users to read arbitrary files via a crafted qcow2 header in an ephemeral or root disk.

CWE-200 Apr 12, 2016

CVE-2015-8749 5.9 MEDIUM EPSS 0.01

The volume_utils._parse_volume_info function in OpenStack Compute (Nova) before 2015.1.3 (kilo) and 12.0.x before 12.0.1 (liberty) includes the connection_info dictionary in the StorageError message when using the Xen backend, which might allow attackers to obtain sensitive password information by reading log files or other unspecified vectors.

CWE-200 Jan 15, 2016

CVE-2015-7548 3.5 LOW EPSS 0.00

OpenStack Compute (Nova) before 2015.1.3 (kilo) and 12.0.x before 12.0.1 (liberty), when using libvirt to spawn instances and use_cow_images is set to false, allow remote authenticated users to read arbitrary files by overwriting an instance disk with a crafted image and requesting a snapshot.
