CVE-2014-3517chainguardopenstack-nova-2025.1+21
EPSS score1.95%
api/metadata/handler.py in OpenStack Compute (Nova) before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2, when proxying metadata requests through Neutron, makes it easier for remote attackers to guess instance ID signatures via a brute-force attack that relies on timing differences in responses to instance metadata requests.CVE-2014-3708chainguardopenstack-nova-2025.1+7EPSS score2.81%
OpenStack Compute (Nova) before 2014.1.4 and 2014.2.x before 2014.2.1 allows remote authenticated users to cause a denial of service (CPU consumption) via an IP filter in a list active servers API request.CVE-2022-47951debiancinder+123EPSS score1.03%
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.CVE-2022-37394debiannova+4EPSS score0.31%
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-2012-2101debiannova+2EPSS score1.46%
Openstack Compute (Nova) Folsom, 2012.1, and 2011.3 does not limit the number of security group rules, which allows remote authenticated users with certain permissions to cause a denial of service (CPU and hard drive consumption) via a network request that triggers a large number of iptables rules.CVE-2012-1585debiannova+2EPSS score2.09%
OpenStack Compute (Nova) Essex before 2011.3 allows remote authenticated users to cause a denial of service (Nova-API log file and disk consumption) via a long server name.CVE-2012-0030debiannova+1EPSS score1.69%
Nova 2011.3 and Essex, when using the OpenStack API, allows remote authenticated users to bypass access restrictions for tenants of other users via an OSAPI request with a modified project_id URI parameter.CVE-2012-3447debiannova+2EPSS score1.93%
virt/disk/api.py in OpenStack Compute (Nova) 2012.1.x before 2012.1.2 and Folsom before Folsom-3 allows remote authenticated users to overwrite arbitrary files via a symlink attack on a file in an image that uses a symlink that is only readable by root. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-3361.CVE-2011-4596debiannova+2EPSS score1.76%
Multiple directory traversal vulnerabilities in OpenStack Nova before 2011.3.1, when the EC2 API and the S3/RegisterImage image-registration method are enabled, allow remote authenticated users to overwrite arbitrary files via a crafted (1) tarball or (2) manifest.CVE-2011-4076debiannova+3EPSS score1.46%
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.CVE-2011-3147debiannova+2EPSS score0.74%
Versions of nova before 2012.1 could expose hypervisor host files to a guest operating system when processing a maliciously constructed qcow filesystem.CVE-2017-16239debiannova+23EPSS score1.42%
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-2017-17051debiannova+3EPSS score1.99%
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.CVE-2017-7214debiannova+21EPSS score2.30%
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.CVE-2017-18191debiannova+23EPSS score3.72%
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-2024-40767ubuntunova+14EPSS score0.95%
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.CVE-2024-32498debiancinder+28EPSS score0.83%
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.CVE-2019-14433canonicalubuntu_linux+23EPSS score1.94%
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.CVE-2026-46448chainguardopenstack-nova-2025.2+4EPSS score0.46%
In OpenStack Nova before 33.0.2, the server create API does not strip certain hint data. The resulting instance has no Placement allocation.CVE-2026-24708debiannova+14EPSS score0.42%
An issue was discovered in OpenStack Nova before 30.2.2, 31 before 31.2.1, and 32 before 32.1.1. By writing a malicious QCOW header to a root or ephemeral disk and then triggering a resize, a user may convince Nova's Flat image backend to call qemu-img without a format restriction, resulting in an unsafe image resize operation that could destroy data on the host system. Only compute nodes using the Flat image backend (usually configured with use_cow_images=False) are affected.
