CVE-2013-2256chainguardopenstack-nova-2025.1+6
EPSS score1.84%
OpenStack Compute (Nova) before 2013.1.3 and Havana before havana-2 does not properly enforce the os-flavor-access:is_public property, which allows remote authenticated users to obtain sensitive information (flavor properties), boot arbitrary flavors, and possibly have other unspecified impacts by guessing the flavor id.CVE-2013-0326debiannova+3EPSS score0.36%
OpenStack nova base images permissions are world readableCVE-2013-7048debiannova+2EPSS score0.48%
OpenStack Compute (Nova) Grizzly 2013.1.4, Havana 2013.2.1, and earlier uses world-writable and world-readable permissions for the temporary directory used to store live snapshots, which allows local users to read and modify live snapshots.CVE-2013-6437debiannova+2EPSS score2.04%
The libvirt driver in OpenStack Compute (Nova) before 2013.2.2 and icehouse before icehouse-2 allows remote authenticated users to cause a denial of service (disk consumption) by creating and deleting instances with unique os_type settings, which triggers the creation of a new ephemeral disk backing file.CVE-2021-3654debiannova+16EPSS score26.79%
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.CVE-2015-0259chainguardopenstack-nova-2025.1+37EPSS score1.07%
OpenStack Compute (Nova) before 2014.1.4, 2014.2.x before 2014.2.3, and kilo before kilo-3 does not validate the origin of websocket requests, which allows remote attackers to hijack the authentication of users for access to consoles via a crafted webpage.CVE-2015-9543debiannova+3EPSS score0.41%
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.CVE-2015-7548debiannova+18EPSS score1.80%
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.CVE-2015-7713chainguardopenstack-nova-2025.1+25EPSS score3.70%
OpenStack Compute (Nova) before 2014.2.4 (juno) and 2015.1.x before 2015.1.2 (kilo) do not properly apply security group changes, which allows remote attackers to bypass intended restriction by leveraging an instance that was running when the change was made.CVE-2015-5162debiancinder+35EPSS score3.09%
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.CVE-2015-8749debiannova+3EPSS score2.24%
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.CVE-2015-3280chainguardopenstack-nova-2025.1+7EPSS score3.38%
OpenStack Compute (nova) before 2014.2.4 (juno) and 2015.1.x before 2015.1.2 (kilo) does not properly delete instances from compute nodes, which allows remote authenticated users to cause a denial of service (disk consumption) by deleting instances while in the resize state.CVE-2015-3241debiannova+19EPSS score3.48%
OpenStack Compute (nova) 2015.1 through 2015.1.1, 2014.2.3, and earlier does not stop the migration process when the instance is deleted, which allows remote authenticated users to cause a denial of service (disk, network, and other resource consumption) by resizing and then deleting an instance.CVE-2016-2140debiannova+19EPSS score2.11%
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.CVE-2020-17376debiannova+21EPSS score1.73%
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.CVE-2014-7230canonicalubuntu_linux+10EPSS score0.49%
The processutils.execute function in OpenStack oslo-incubator, Cinder, Nova, and Trove before 2013.2.4 and 2014.1 before 2014.1.3 allows local users to obtain passwords from commands that cause a ProcessExecutionError by reading the log.CVE-2014-7231debianpython-oslo.utils+5EPSS score0.53%
The strutils.mask_password function in the OpenStack Oslo utility library, Cinder, Nova, and Trove before 2013.2.4 and 2014.1 before 2014.1.3 does not properly mask passwords when logging commands, which allows local users to obtain passwords by reading the log.CVE-2014-8333debiannova+3EPSS score2.02%
The VMware driver in OpenStack Compute (Nova) before 2014.1.4 allows remote authenticated users to cause a denial of service (disk consumption) by deleting an instance in the resize state.CVE-2014-8750openstacknova+14EPSS score2.03%
Race condition in the VMware driver in OpenStack Compute (Nova) before 2014.1.4 and 2014.2 before 2014.2rc1 allows remote authenticated users to access unintended consoles by spawning an instance that triggers the same VNC port to be allocated to two different instances.CVE-2014-3608chainguardopenstack-nova-2025.1+7EPSS score1.73%
The VMWare driver in OpenStack Compute (Nova) before 2014.1.3 allows remote authenticated users to bypass the quota limit and cause a denial of service (resource consumption) by putting the VM into the rescue state, suspending it, which puts into an ERROR state, and then deleting the image. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2573.
