CVSS: 5.4EPSS: 0%CPEs: 15EXPL: 1CVE-2023-6134 – Keycloak: reflected xss via wildcard in oidc redirect_uri
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') •

https://notcve.org/view.php?id=CVE-2023-0264
A flaw was found in Keycloaks OpenID Connect user authentication, which may incorrectly authenticate requests. An authenticated attacker who could obtain information from a user request within the same realm could use that data to impersonate the victim and generate new session tokens. This issue could impact confidentiality, integrity, and availability. Se ha encontrado un fallo en la autenticación de usuarios en OpenID Connect de Keycloak, que podría autenticar incorrectamente las solicitudes. Un atacante autenticado que pudiera obtener información de una solicitud de usuario dentro del mismo entorno, podría utilizar esos datos para hacerse pasar por la víctima y generar nuevos tokens de sesión. • https://github.com/twwd/CVE-2023-0264 https://access.redhat.com/security/cve/CVE-2023-0264 https://bugzilla.redhat.com/show_bug.cgi?id=2160585 • CWE-287: Improper Authentication CWE-303: Incorrect Implementation of Authentication Algorithm •

CVSS: 6.8EPSS: 0%CPEs: 8EXPL: 0CVE-2021-3827 – keycloak-server-spi-private: ECP SAML binding bypasses authentication flows
https://notcve.org/view.php?id=CVE-2021-3827
A flaw was found in keycloak, where the default ECP binding flow allows other authentication flows to be bypassed. By exploiting this behavior, an attacker can bypass the MFA authentication by sending a SOAP request with an AuthnRequest and Authorization header with the user's credentials. The highest threat from this vulnerability is to confidentiality and integrity. Se ha encontrado un fallo en keycloak, en el que el flujo de vinculación ECP por defecto permite omitir otros flujos de autenticación. Al explotar este comportamiento, un atacante puede omitir la autenticación MFA mediante el envío de una petición SOAP con un encabezado AuthnRequest y Authorization con las credenciales del usuario. • https://access.redhat.com/security/cve/CVE-2021-3827 https://bugzilla.redhat.com/show_bug.cgi?id=2007512 https://github.com/keycloak/keycloak/commit/44000caaf5051d7f218d1ad79573bd3d175cad0d https://github.com/keycloak/keycloak/security/advisories/GHSA-4pc7-vqv5-5r3v • CWE-287: Improper Authentication •
