URL Redirection to Untrusted Site ('Open Redirect')
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.

OpenStack Cinder, Glance, and Nova vulnerable to arbitrary file access
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.

OpenStack Cinder, glance, and Nova vulnerable to Path Traversal
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.

OpenStack Compute (Nova) allows remote attackers to bypass intended restriction
A vulnerability was discovered in the way OpenStack Compute (nova) networking handled security group updates; changes were not applied to already running VM instances. A remote attacker could use this flaw to access running VM instances.

Insufficient Verification of Data Authenticity
It was discovered that the OpenStack Compute (nova) console websocket does not correctly verify the origin header. An attacker could use this flaw to conduct a cross-site websocket hijack attack. Note that only Compute setups with VNC or SPICE enabled were affected by this flaw.

Exposure of Sensitive Information to an Unauthorized Actor
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.

OpenStack Compute (Nova) Denial of Service vulnerability
A denial of service flaw was found in the way OpenStack Compute (nova) looked up VM instances based on an IP address filter. An attacker with sufficient privileges on an OpenStack installation with a large amount of VMs could use this flaw to cause the main nova process to block for an extended amount of time.
