It was discovered that OpenShift Container Platform's (OCP) distribution of Kibana could open in an iframe, which made it possible to intercept and manipulate requests. This flaw allows an attacker to trick a user into performing arbitrary actions in OCP's distribution of Kibana, such as clickjacking. Se detectó que la distribución Kibana OpenShift Container Platform (OCP) podía abrirse en un iframe, lo que permitía interceptar y manipular las peticiones. Este fallo permite a un atacante engañar a un usuario para llevar a cabo acciones arbitrarias en la distribución de Kibana de OCP, como el clickjacking • https://bugzilla.redhat.com/show_bug.cgi?id=1834550 https://access.redhat.com/security/cve/CVE-2020-10743 • CWE-358: Improperly Implemented Security Check for Standard CWE-1021: Improper Restriction of Rendered UI Layers or Frames •
CVSS: 6.4EPSS: 0%CPEs: 32EXPL: 0CVE-2020-15705 – GRUB2: avoid loading unsigned kernels when GRUB is booted directly under secureboot without shim
https://notcve.org/view.php?id=CVE-2020-15705
GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim. This issue affects GRUB2 version 2.04 and prior versions. GRUB2 presenta un fallo al comprobar la firma del kernel cuando se inicia directamente sin cuña, permitiendo que el arranque seguro sea omitido. Esto solo afecta a los sistemas en los que el certificado de firma del kernel ha sido importado directamente a la base de datos de arranque seguro y la imagen de GRUB es iniciada directamente sin el uso de cuña. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00067.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00069.html http://ubuntu.com/security/notices/USN-4432-1 http://www.openwall.com/lists/oss-security/2020/07/29/3 http://www.openwall.com/lists/oss-security/2021/03/02/3 http://www.openwall.com/lists/oss-security/2021/09/17/2 http://www.openwall.com/lists/oss-security/2021/09/17/4 http://www.openwall.com/lists/oss-security&#x • CWE-347: Improper Verification of Cryptographic Signature CWE-440: Expected Behavior Violation •

GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2 version 2.04 and prior versions. GRUB2 contiene una condición de carrera en la función grub_script_function_create() que conlleva a una vulnerabilidad de uso de la memoria previamente liberada la cual puede ser desencadenada al redefinir una función mientras la misma función ya se está ejecutando, conllevando a una ejecución de código arbitrario y a una omisión de restricción de arranque seguro.

CVSS: 6.4EPSS: 0%CPEs: 33EXPL: 1CVE-2020-15707 – GRUB2 contained integer overflows when handling the initrd command, leading to a heap-based buffer overflow.
https://notcve.org/view.php?id=CVE-2020-15707
Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions. Se detectaron desbordamientos de enteros en las funciones grub_cmd_initrd y grub_initrd_init en el componente efilinux de GRUB2, como se incluye en Debian, Red Hat y Ubuntu (la funcionalidad no está incluida aguas arriba de GRUB2), conllevando a un desbordamiento del búfer en la región heap de la memoria. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00016.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00017.html http://ubuntu.com/security/notices/USN-4432-1 http://www.openwall.com/lists/oss-security/2020/07/29/3 https://access.redhat.com/security/vulnerabilities/grub2bootloader https://lists.gnu.org/archive/html/grub-devel/2020-07/msg00034.html https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/ADV200011 https://security.gentoo.org/ • CWE-190: Integer Overflow or Wraparound CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

A flaw was found in the OpenShift API Server, where it failed to sufficiently protect OAuthTokens by leaking them into the logs when an API Server panic occurred. This flaw allows an attacker with the ability to cause an API Server error to read the logs, and use the leaked OAuthToken to log into the API Server with the leaked token. Se encontró un fallo en el OpenShift API Server, donde presento un fallo al proteger de manera suficiente a los OAuthTokens al filtrarlos en los registros cuando se produjo un pánico del API Server.
