Descriptions
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, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix this issue by removing support for message lookup patterns and disabling JNDI functionality by default.
Se descubrió que la corrección para abordar CVE-2021-44228 en Apache Log4j versiones 2.15.0 estaba incompleta en ciertas configuraciones no predeterminadas. Esto podría permitir a los atacantes con control sobre los datos de entrada de Thread Context Map (MDC) cuando la configuración de registro utiliza un Pattern Layout no predeterminado con un Context Lookup (por ejemplo, $${ctx:loginId}) o un Thread Context Map pattern (%X, %mdc, o %MDC) para elaborar datos de entrada maliciosos utilizando un patrón JNDI Lookup que resulta en una fuga de información y ejecución de código remoto en algunos entornos y ejecución de código local en todos los entornos. Log4j versiones 2.16.0 (Java 8) y 2.12.2 (Java 7) solucionan este problema eliminando el soporte para los patrones de búsqueda de mensajes y deshabilitando la funcionalidad JNDI por defecto
A flaw was found in the Apache Log4j logging library in versions from 2.0.0 and before 2.16.0. A remote attacker with control over Thread Context Map (MDC) input data could craft malicious input using a JNDI Lookup pattern resulting in remote code execution (RCE) in a limited number of environments.
Apache Log4j2 contains a deserialization of untrusted data vulnerability due to the incomplete fix of CVE-2021-44228, where the Thread Context Lookup Pattern is vulnerable to remote code execution in certain non-default configurations.
