CVE-2022-2447 6.6 MEDIUM EPSS 0.01

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.

CWE-672 Sep 01, 2022

CVE-2021-3563 7.4 HIGH EPSS 0.00

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.

CWE-863 Aug 26, 2022

CVE-2021-38155 7.5 HIGH EPSS 0.01

OpenStack Keystone 10.x through 16.x before 16.0.2, 17.x before 17.0.1, 18.x before 18.0.1, and 19.x before 19.0.1 allows information disclosure during account locking (related to PCI DSS features). By guessing the name of an account and failing to authenticate multiple times, any unauthenticated actor could both confirm the account exists and obtain that account's corresponding UUID, which might be leveraged for other unrelated attacks. All deployments enabling security_compliance.lockout_failure_attempts are affected.

CWE-307 Aug 06, 2021

CVE-2020-12692 5.4 MEDIUM EPSS 0.00

An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. The EC2 API doesn't have a signature TTL check for AWS Signature V4. An attacker can sniff the Authorization header, and then use it to reissue an OpenStack token an unlimited number of times.

CWE-294 May 07, 2020

CVE-2020-12691 8.8 HIGH EPSS 0.04

An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. Any authenticated user can create an EC2 credential for themselves for a project that they have a specified role on, and then perform an update to the credential user and project, allowing them to masquerade as another user. This potentially allows a malicious user to act as the admin on a project another user has the admin role on, which can effectively grant that user global admin privileges.

CWE-863 May 07, 2020

CVE-2020-12690 8.8 HIGH EPSS 0.01

An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. The list of roles provided for an OAuth1 access token is silently ignored. Thus, when an access token is used to request a keystone token, the keystone token contains every role assignment the creator had for the project. This results in the provided keystone token having more role assignments than the creator intended, possibly giving unintended escalated access.

CWE-613 May 07, 2020

CVE-2020-12689 8.8 HIGH EPSS 0.01

An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. Any user authenticated within a limited scope (trust/oauth/application credential) can create an EC2 credential with an escalated permission, such as obtaining admin while the user is on a limited viewer role. This potentially allows a malicious user to act as the admin on a project another user has the admin role on, which can effectively grant that user global admin privileges.

CWE-269 May 07, 2020

CVE-2019-19687 8.8 HIGH EPSS 0.01

OpenStack Keystone 15.0.0 and 16.0.0 is affected by Data Leakage in the list credentials API. Any user with a role on a project is able to list any credentials with the /v3/credentials API when enforce_scope is false. Users with a role on a project are able to view any other users' credentials, which could (for example) leak sign-on information for Time-based One Time Passwords (TOTP). Deployments with enforce_scope set to false are affected. (There will be a slight performance impact for the list credentials API once this issue is fixed.)

CWE-522 Dec 09, 2019

CVE-2012-1572 7.5 HIGH EPSS 0.00

OpenStack Keystone: extremely long passwords can crash Keystone by exhausting stack space

CWE-400 Nov 12, 2019

CVE-2013-2255 5.9 MEDIUM EPSS 0.00

HTTPSConnections in OpenStack Keystone 2013, OpenStack Compute 2013.1, and possibly other OpenStack components, fail to validate server-side SSL certificates.

CWE-295 Nov 01, 2019

CVE-2018-20170 5.3 MEDIUM EPSS 0.00

OpenStack Keystone through 14.0.1 has a user enumeration vulnerability because invalid usernames have much faster responses than valid ones for a POST /v3/auth/tokens request. NOTE: the vendor's position is that this is a hardening opportunity, and not necessarily an issue that should have an OpenStack Security Advisory

CWE-200 Dec 17, 2018

CVE-2018-14432 5.3 MEDIUM EPSS 0.01

In the Federation component of OpenStack Keystone before 11.0.4, 12.0.0, and 13.0.0, an authenticated "GET /v3/OS-FEDERATION/projects" request may bypass intended access restrictions on listing projects. An authenticated user may discover projects they have no authority to access, leaking all projects in the deployment and their attributes. Only Keystone with the /v3/OS-FEDERATION endpoint enabled via policy.json is affected.

CWE-200 Jul 31, 2018

CVE-2015-7546 7.5 HIGH EPSS 0.00

The identity service in OpenStack Identity (Keystone) before 2015.1.3 (Kilo) and 8.0.x before 8.0.2 (Liberty) and keystonemiddleware (formerly python-keystoneclient) before 1.5.4 (Kilo) and Liberty before 2.3.3 does not properly invalidate authorization tokens when using the PKI or PKIZ token providers, which allows remote authenticated users to bypass intended access restrictions and gain access to cloud resources by manipulating byte fields within a revoked token.

CWE-522 Feb 03, 2016

CVE-2015-3646 EPSS 0.00

OpenStack Identity (Keystone) before 2014.1.5 and 2014.2.x before 2014.2.4 logs the backend_argument configuration option content, which allows remote authenticated users to obtain passwords and other sensitive backend information by reading the Keystone logs.

CWE-200 May 12, 2015

CVE-2014-0204 EPSS 0.00

OpenStack Identity (Keystone) before 2014.1.1 does not properly handle when a role is assigned to a group that has the same ID as a user, which allows remote authenticated users to gain privileges that are assigned to a group with the same ID.

CWE-269 Nov 03, 2014

CVE-2014-3520 EPSS 0.00

OpenStack Identity (Keystone) before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2 allows remote authenticated trustees to gain access to an unauthorized project for which the trustor has certain roles via the project ID in a V2 API trust token request.

CWE-863 Oct 26, 2014

CVE-2014-3621 EPSS 0.00

The catalog url replacement in OpenStack Identity (Keystone) before 2013.2.3 and 2014.1 before 2014.1.2.1 allows remote authenticated users to read sensitive configuration options via a crafted endpoint, as demonstrated by "$(admin_token)" in the publicurl endpoint field.

CWE-200 Oct 02, 2014

CVE-2014-5253 EPSS 0.00

OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 does not properly revoke tokens when a domain is invalidated, which allows remote authenticated users to retain access via a domain-scoped token for that domain.

CWE-255 Aug 25, 2014

CVE-2014-5252 EPSS 0.00

The V3 API in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 updates the issued_at value for UUID v2 tokens, which allows remote authenticated users to bypass the token expiration and retain access via a verification (1) GET or (2) HEAD request to v3/auth/tokens/.

CWE-255 Aug 25, 2014

CVE-2014-5251 EPSS 0.00

The MySQL token driver in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 stores timestamps with the incorrect precision, which causes the expiration comparison for tokens to fail and allows remote authenticated users to retain access via an expired token.

CWE-255 Aug 25, 2014
