CVE-2021-38155 [HIGH] CWE-307 CVE-2021-38155: 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 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

CVE-2020-12689 [HIGH] CWE-269 CVE-2020-12689: An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. Any user authenticated with 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 proj

CVE-2020-12691 [HIGH] CWE-863 CVE-2020-12691: An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. Any authenticated user can 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 a

CVE-2020-12690 [HIGH] CWE-613 CVE-2020-12690: An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. The list of roles provided 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 rol

CVE-2020-12692 [MEDIUM] CWE-294 CVE-2020-12692: An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. The EC2 API doesn't have a 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.

CVE-2019-19687 [HIGH] CWE-522 CVE-2019-19687: OpenStack Keystone 15.0.0 and 16.0.0 is affected by Data Leakage in the list credentials API. Any us 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 Ti

CVE-2013-2255 [MEDIUM] CWE-295 CVE-2013-2255: HTTPSConnections in OpenStack Keystone 2013, OpenStack Compute 2013.1, and possibly other OpenStack HTTPSConnections in OpenStack Keystone 2013, OpenStack Compute 2013.1, and possibly other OpenStack components, fail to validate server-side SSL certificates.

CVE-2018-20170 [MEDIUM] CWE-200 CVE-2018-20170: OpenStack Keystone through 14.0.1 has a user enumeration vulnerability because invalid usernames hav 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

CVE-2018-14432 [MEDIUM] CWE-200 CVE-2018-14432: In the Federation component of OpenStack Keystone before 11.0.4, 12.0.0, and 13.0.0, an authenticate 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 Key

CVE-2015-7546 [HIGH] CWE-522 CVE-2015-7546: The identity service in OpenStack Identity (Keystone) before 2015.1.3 (Kilo) and 8.0.x before 8.0.2 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 i

CVE-2015-3646 [MEDIUM] CWE-200 CVE-2015-3646: OpenStack Identity (Keystone) before 2014.1.5 and 2014.2.x before 2014.2.4 logs the backend_argument 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.

CVE-2014-0204 [MEDIUM] CWE-269 CVE-2014-0204: OpenStack Identity (Keystone) before 2014.1.1 does not properly handle when a role is assigned to a 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.

CVE-2014-3520 [MEDIUM] CWE-863 CVE-2014-3520: OpenStack Identity (Keystone) before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2 allows 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.

CVE-2014-3621 [MEDIUM] CWE-200 CVE-2014-3621: The catalog url replacement in OpenStack Identity (Keystone) before 2013.2.3 and 2014.1 before 2014. 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.

CVE-2014-5252 [MEDIUM] CWE-255 CVE-2014-5252: The V3 API in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 update 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/.

CVE-2014-5253 [MEDIUM] CWE-255 CVE-2014-5253: OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 does not properly re 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.

CVE-2014-5251 [MEDIUM] CWE-255 CVE-2014-5251: The MySQL token driver in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before J 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.
