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: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2023-6476 – Cri-o: pods are able to break out of resource confinement on cgroupv2
https://notcve.org/view.php?id=CVE-2023-6476
A flaw was found in CRI-O that involves an experimental annotation leading to a container being unconfined. This may allow a pod to specify and get any amount of memory/cpu, circumventing the kubernetes scheduler and potentially resulting in a denial of service in the node. Se encontró una falla en CRI-O que involucra una anotación experimental que lleva a que un contenedor no esté confinado. Esto puede permitir que un pod especifique y obtenga cualquier cantidad de memoria/CPU, eludiendo el programador de Kubernetes y potencialmente provocando una denegación de servicio en el nodo. • https://access.redhat.com/errata/RHSA-2024:0195 https://access.redhat.com/errata/RHSA-2024:0207 https://access.redhat.com/security/cve/CVE-2023-6476 https://bugzilla.redhat.com/show_bug.cgi?id=2253994 • CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2023-6134
A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748. Se encontró una falla en Keycloak que impide ciertos esquemas en las redirecciones, pero los permite si se agrega un comodín al token. Este problema podría permitir que un atacante envíe una solicitud especialmente manipulada que dé lugar a cross-site scripting (XSS) o más ataques. • 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
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-2023-5408
A privilege escalation flaw was found in the node restriction admission plugin of the kubernetes api server of OpenShift. A remote attacker who modifies the node role label could steer workloads from the control plane and etcd nodes onto different worker nodes and gain broader access to the cluster. Se encontró una falla de escalada de privilegios en el complemento de admisión de restricción de nodos del servidor API de Kubernetes de OpenShift. Un atacante remoto que modifique la etiqueta de función del nodo podría dirigir cargas de trabajo desde el plano de control y los nodos etcd a diferentes nodos trabajadores y obtener un acceso más amplio al clúster. • https://access.redhat.com/errata/RHSA-2023:5006 https://access.redhat.com/errata/RHSA-2023:6130 https://access.redhat.com/errata/RHSA-2023:6842 https://access.redhat.com/errata/RHSA-2023:7479 https://access.redhat.com/security/cve/CVE-2023-5408 https://bugzilla.redhat.com/show_bug.cgi?id=2242173 https://github.com/openshift/kubernetes/pull/1736 • CWE-269: Improper Privilege Management •
