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 •

CVSS: 7.8EPSS: 0%CPEs: 6EXPL: 0CVE-2021-45463 – gegl: shell expansion via a crafted pathname
https://notcve.org/view.php?id=CVE-2021-45463
load_cache in GEGL before 0.4.34 allows shell expansion when a pathname in a constructed command line is not escaped or filtered. This is caused by use of the system library function for execution of the ImageMagick convert fallback in magick-load. NOTE: GEGL releases before 0.4.34 are used in GIMP releases before 2.10.30; however, this does not imply that GIMP builds enable the vulnerable feature. load_cache en GEGL antes de la versión 0.4.34 permite la expansión del shell cuando un nombre de ruta en una línea de comando construida no está escapado o filtrado. Esto es causado por el uso de la función de la biblioteca del sistema para la ejecución de la conversión de ImageMagick en magick-load. NOTA: Las versiones de GEGL anteriores a la versión 0.4.34 se utilizan en las versiones de GIMP anteriores a la versión 2.10.30; sin embargo, esto no implica que las construcciones de GIMP habiliten la característica vulnerable Due to the use of the system command in the Magick-Load op used by gegl an attacker is able to craft a command line path that is able to lead to the execution of arbitrary shell commands that impacts availability, confidentiality and integrity. • https://gitlab.gnome.org/GNOME/gegl/-/blob/master/docs/NEWS.adoc https://gitlab.gnome.org/GNOME/gegl/-/commit/bfce470f0f2f37968862129d5038b35429f2909b https://gitlab.gnome.org/GNOME/gegl/-/issues/298 https://gitlab.gnome.org/GNOME/gimp/-/commit/e8a31ba4f2ce7e6bc34882dc27c97fba993f5868 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CG635WJCNXHJM5U4BGMAAP4NK2YFTQXK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZP5NDNOTMPI335FXE7VUPW7 • CWE-20: Improper Input Validation •
