If the YARN cluster is accepting work from remote (authenticated) users, this MAY permit remote users to gain root privileges.\n\nHadoop 3.3.0 updated the \" YARN Secure Containers https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/SecureContainer.html \" to add a feature for executing user-submitted applications in isolated linux containers.\n\nThe native binary HADOOP_HOME/bin/container-executor is used to launch these containers; it must be owned by root and have the suid bit set in order for the YARN processes to run the containers as the specific users submitting the jobs.\n\nThe patch \" YARN-10495 https://issues.apache.org/jira/browse/YARN-10495 . make the rpath of container-executor configurable\" modified the library loading path for loading .so files from \"$ORIGIN/\" to \"\"$ORIGIN/:../lib/native/\". This is the a path through which libcrypto.so is located. Thus it is is possible for a user with reduced privileges to install a malicious libcrypto library into a path to which they have write access, invoke the container-executor command, and have their modified library executed as root.\nIf the YARN cluster is accepting work from remote (authenticated) users, and these users' submitted job are executed in the physical host, rather than a container, then the CVE permits remote users to gain root privileges.\n\nThe fix for the vulnerability is to revert the change, which is done in YARN-11441 https://issues.apache.org/jira/browse/YARN-11441 , \"Revert YARN-10495\". This patch is in hadoop-3.3.5.\n\nTo determine whether a version of container-executor is vulnerable, use the readelf command.

Si el cl\u00faster YARN acepta trabajo de usuarios remotos (autenticados), esto PUEDE permitir que los usuarios remotos obtengan privilegios de root. Hadoop 3.3.0 actualiz\u00f3 \" YARN Secure Containers https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/SecureContainer.html \" para agregar una funci\u00f3n para ejecutar aplicaciones enviadas por el usuario de forma aislada contenedores de Linux. El binario nativo HADOOP_HOME/bin/container-executor se utiliza para lanzar estos contenedores; debe ser propiedad de root y tener el bit suid configurado para que los procesos YARN ejecuten los contenedores como los usuarios espec\u00edficos que env\u00edan los trabajos. El parche \"YARN-10495 https://issues.apache.org/jira/browse/YARN-10495. make the rpath of container-executor configurable\" modific\u00f3 la ruta de carga de la librer\u00eda para cargar archivos .so de \"$ORIGIN/\" a \"\"$ORIGIN/:../lib/native/\". Esta es la ruta a trav\u00e9s de la cual se encuentra libcrypto.so. Por lo tanto, es posible que un usuario con privilegios reducidos instale una librer\u00eda libcrypto maliciosa en una ruta a la que tienen acceso de escritura, invocan el comando contenedor-ejecutor y ejecutan su librer\u00eda modificada como root. Si el cl\u00faster YARN acepta trabajo de usuarios remotos (autenticados) y el trabajo enviado por estos usuarios se ejecuta en el host f\u00edsico, en lugar de un contenedor, entonces el CVE permite a los usuarios remotos obtener privilegios de root. La soluci\u00f3n para la vulnerabilidad es revertir el cambio, lo cual se realiza en YARN-11441 https://issues.apache.org/jira/browse/YARN-11441, \"Revertir YARN-10495\".
