Openstack Platform Security Vulnerabilities

CVE-2017-15114

When libvirtd is configured by OSP director (tripleo-heat-templates) to use the TLS transport it defaults to the same certificate authority as all non-libvirtd services. As no additional authentication is configured this allows these services to connect to libvirtd (which is equivalent to root acce...

hw/ide/pci.c in QEMU before 5.1.1 can trigger a NULL pointer dereference because it lacks a pointer check before an ide_cancel_dma_sync call.

CVE-2020-27781

User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting in potential privilege escalation. An Open Stack Manila user can request access to a share to an arbitrary cephx user, including existing users. The access key is retrieved via the interface dri...

CVE-2021-20257

An infinite loop flaw was found in the e1000 NIC emulator of the QEMU.

A flaw was found in openstack-neutron's default Open vSwitch firewall rules. By sending carefully crafted packets, anyone in control of a server instance connected to the virtual switch can impersonate the IPv6 addresses of other systems on the network, resulting in denial of service or in some cas...

CVE-2021-20270

An infinite loop in SMLLexer in Pygments versions 1.5 to 2.7.3 may lead to denial of service when performing syntax highlighting of a Standard ML (SML) source file, as demonstrated by input that only contains the "exception" keyword.

CVE-2021-3563

A flaw was found in openstack-keystone. Only the first 72 characters of an application secret are verified allowing attackers bypass some password complexity which administrators may be counting on. The highest threat from this vulnerability is to data confidentiality and integrity.

CVE-2021-3654

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-2021-3979

A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.

CVE-2022-0718

A flaw was found in python-oslo-utils. Due to improper parsing, passwords with a double quote ( " ) in them cause incorrect masking in debug logs, causing any part of the password after the double quote to be plaintext.

CVE-2022-0866

This is a concurrency issue that can result in the wrong caller principal being returned from the session context of an EJB that is configured with a RunAs principal. In particular, the org.jboss.as.ejb3.component.EJBComponent class has an incomingRunAsIdentity field. This field is used by the org....

CVE-2022-2132

A permissive list of allowed inputs flaw was found in DPDK. This issue allows a remote attacker to cause a denial of service triggered by sending a crafted Vhost header to DPDK.

CVE-2022-23451

An authorization flaw was found in openstack-barbican. The default policy rules for the secret metadata API allowed any authenticated user to add, modify, or delete metadata from any secret regardless of ownership. This flaw allows an attacker on the network to modify or delete protected data, caus...

CVE-2022-23452

An authorization flaw was found in openstack-barbican, where anyone with an admin role could add secrets to a different project container. This flaw allows an attacker on the network to consume protected resources and cause a denial of service.

CVE-2022-2447

A flaw was found in Keystone. There is a time lag (up to one hour in a default configuration) between when security policy says a token should be revoked from when it is actually revoked. This could allow a remote administrator to secretly maintain access for longer than expected.

CVE-2022-3100

A flaw was found in the openstack-barbican component. This issue allows an access policy bypass via a query string when accessing the API.

CVE-2022-3261

A flaw was found in OpenStack. Multiple components show plain-text passwords in /var/log/messages during the OpenStack overcloud update run, leading to a disclosure of sensitive information problem.

CVE-2022-3277

An uncontrolled resource consumption flaw was found in openstack-neutron. This flaw allows a remote authenticated user to query a list of security groups for an invalid project. This issue creates resources that are unconstrained by the user's quota. If a malicious user were to submit a significant...

CVE-2022-3596

An information leak was found in OpenStack's undercloud. This flaw allows unauthenticated, remote attackers to inspect sensitive data after discovering the IP address of the undercloud, possibly leading to compromising private information, including administrator access credentials.

CVE-2023-1108

A flaw was found in undertow. This issue makes achieving a denial of service possible due to an unexpected handshake status updated in SslConduit, where the loop never terminates.

CVE-2023-1625

An information leak was discovered in OpenStack heat. This issue could allow a remote, authenticated attacker to use the 'stack show' command to reveal parameters which are supposed to remain hidden. This has a low impact to the confidentiality, integrity, and availability of the system.

CVE-2023-1633

A credentials leak flaw was found in OpenStack Barbican. This flaw allows a local authenticated attacker to read the configuration file, gaining access to sensitive credentials.

CVE-2023-1636

A vulnerability was found in OpenStack Barbican containers. This vulnerability is only applicable to deployments that utilize an all-in-one configuration. Barbican containers share the same CGROUP, USER, and NET namespace with the host system and other OpenStack services. If any service is compromi...

CVE-2023-1668

A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildca...

CVE-2023-3354

A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU...

CVE-2023-3637

An uncontrolled resource consumption flaw was found in openstack-neutron. This flaw allows a remote authenticated user to query a list of security groups for an invalid project. This issue creates resources that are unconstrained by the user's quota. If a malicious user were to submit a significant...

CVE-2023-44487

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

CVE-2023-48795

The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connecti...

CVE-2023-5625

A regression was introduced in the Red Hat build of python-eventlet due to a change in the patch application strategy, resulting in a patch for CVE-2021-21419 not being applied for all builds of all products.
