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 •
