- CVE-2021-43890Alta7.1
We have investigated reports of a spoofing vulnerability in AppX installer that affects Microsoft Windows. Microsoft is aware of attacks that attempt to exploit this vulnerability by using specially crafted packages that include the malware family known as Emotet/Trickbot/Bazaloader. An attacker could craft a malicious attachment to be used in phishing campaigns. The attacker would then have to convince the user to open the specially crafted attachment. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Please see the Security Updates table for the link to the updated app. Alternatively you can download and install the Installer using the links provided in the FAQ section. Please see the Mitigations and Workaround sections for important information about steps you can take to protect your system from this vulnerability. December 27 2023 Update: In recent months, Microsoft Threat Intelligence has seen an increase in activity from threat actors leveraging social engineering and phishing techniques to target Windows OS users and utilizing the ms-appinstaller URI scheme. To address this increase in activity, we have updated the App Installer to disable the ms-appinstaller protocol by default and recommend other potential mitigations.

Windows Common Log File System Driver Elevation of Privilege Vulnerability
- CVE-2021-45046Crítica9.0
It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allows attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix this issue by removing support for message lookup patterns and disabling JNDI functionality by default.

- CVE-2021-44228Crítica10.0
Las funciones JNDI de Apache Log4j2 desde 2.0-beta9 hasta 2.15.0 (excluidas las versiones de seguridad 2.12.2, 2.12.3 y 2.3.1) utilizadas en la configuración, los mensajes de log y los parámetros no protegen contra LDAP controlado por un atacante y otros endpoints relacionados con JNDI. Un atacante que pueda controlar los mensajes de log o los parámetros de los mensajes de log puede ejecutar código arbitrario cargado desde servidores LDAP cuando la sustitución de message lookup está habilitada. A partir de log4j 2.15.0, este comportamiento se ha desactivado por defecto. A partir de la versión 2.16.0 (junto con 2.12.2, 2.12.3 y 2.3.1), esta funcionalidad se ha eliminado por completo. Tenga en cuenta que esta vulnerabilidad es específica de log4j-core y no afecta a log4net, log4cxx ni a otros proyectos de Apache Logging Services.

- CVE-2021-41277Crítica10.0
Metabase is an open source data analytics platform. In affected versions a security issue has been discovered with the custom GeoJSON map (`admin->settings->maps->custom maps->add a map`) support and potential local file inclusion (including environment variables). URLs were not validated prior to being loaded. This issue is fixed in a new maintenance release (0.40.5 and 1.40.5), and any subsequent release after that. If you’re unable to upgrade immediately, you can mitigate this by including rules in your reverse proxy or load balancer or WAF to provide a validation filter before the application.
