CVSS: 7.1EPSS: 0%CPEs: 17EXPL: 0CVE-2023-6291 – Keycloak: redirect_uri validation bypass
https://notcve.org/view.php?id=CVE-2023-6291
A flaw was found in the redirect_uri validation logic in Keycloak. This issue may allow a bypass of otherwise explicitly allowed hosts. A successful attack may lead to an access token being stolen, making it possible for the attacker to impersonate other users. Se encontró un fallo en la lógica de validación de redirect_uri en Keycloak. Este problema puede permitir la omisión de hosts permitidos explícitamente. • https://access.redhat.com/errata/RHSA-2023:7854 https://access.redhat.com/errata/RHSA-2023:7855 https://access.redhat.com/errata/RHSA-2023:7856 https://access.redhat.com/errata/RHSA-2023:7857 https://access.redhat.com/errata/RHSA-2023:7858 https://access.redhat.com/errata/RHSA-2023:7860 https://access.redhat.com/errata/RHSA-2023:7861 https://access.redhat.com/errata/RHSA-2024:0798 https://access.redhat.com/errata/RHSA-2024:0799 https://access.redhat.com/errata/RHSA • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVSS: 7.7EPSS: 0%CPEs: 15EXPL: 1CVE-2023-6563 – Keycloak: offline session token dos
https://notcve.org/view.php?id=CVE-2023-6563
An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system. Se descubrió una vulnerabilidad de consumo de memoria sin restricciones en Keycloak. Se puede activar en entornos que tienen millones de tokens fuera de línea (> 500.000 usuarios, cada uno con al menos 2 sesiones guardadas). • https://access.redhat.com/errata/RHSA-2023:7854 https://access.redhat.com/errata/RHSA-2023:7855 https://access.redhat.com/errata/RHSA-2023:7856 https://access.redhat.com/errata/RHSA-2023:7857 https://access.redhat.com/errata/RHSA-2023:7858 https://access.redhat.com/security/cve/CVE-2023-6563 https://bugzilla.redhat.com/show_bug.cgi?id=2253308 https://github.com/keycloak/keycloak/issues/13340 • CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2023-3223
A flaw was found in undertow. Servlets annotated with @MultipartConfig may cause an OutOfMemoryError due to large multipart content. This may allow unauthorized users to cause remote Denial of Service (DoS) attack. If the server uses fileSizeThreshold to limit the file size, it's possible to bypass the limit by setting the file name in the request to null.

CVSS: 8.1EPSS: 0%CPEs: 14EXPL: 0CVE-2023-2585 – Keycloak: client access via device auth request spoof
https://notcve.org/view.php?id=CVE-2023-2585
Keycloak's device authorization grant does not correctly validate the device code and client ID. An attacker client could abuse the missing validation to spoof a client consent request and trick an authorization admin into granting consent to a malicious OAuth client or possible unauthorized access to an existing OAuth client. La concesión de autorización del dispositivo de Keycloak no valida correctamente el código del dispositivo y la identificación del cliente. Un cliente atacante podría abusar de la validación faltante para falsificar una solicitud de consentimiento del cliente y engañar a un administrador de autorización para que otorgue el consentimiento a un cliente OAuth malicioso o un posible acceso no autorizado a un cliente OAuth existente. • https://access.redhat.com/errata/RHSA-2023:3883 https://access.redhat.com/errata/RHSA-2023:3884 https://access.redhat.com/errata/RHSA-2023:3885 https://access.redhat.com/errata/RHSA-2023:3888 https://access.redhat.com/errata/RHSA-2023:3892 https://access.redhat.com/security/cve/CVE-2023-2585 https://bugzilla.redhat.com/show_bug.cgi?id=2196335 • CWE-358: Improperly Implemented Security Check for Standard •
