      "value": "Control inadecuado de recursos de código administrados dinámicamente, carga sin restricciones de archivos con tipos peligrosos, inclusión de funcionalidad de vulnerabilidad de esfera de control no confiable en Apache Solr. Este problema afecta a Apache Solr: desde 6.0.0 hasta 8.11.2, desde 9.0.0 antes de 9.4 .1. En las versiones afectadas, Solr ConfigSets aceptó la carga de archivos jar y de clase de Java a través de la API de ConfigSets. Al realizar una copia de seguridad de las colecciones de Solr, estos archivos de configuración se guardarán en el disco cuando se utilice LocalFileSystemRepository (el valor predeterminado para las copias de seguridad). Si la copia de seguridad se guardó en un directorio que Solr usa en su ClassPath/ClassLoaders, entonces los archivos jar y de clase estarían disponibles para usar con cualquier ConfigSet, confiable o no confiable. Cuando Solr se ejecuta de forma segura (autorización habilitada), como se sugiere encarecidamente, esta vulnerabilidad se limita a ampliar los permisos de copia de seguridad con la capacidad de agregar librerías. Se recomienda a los usuarios actualizar a la versión 8.11.3 o 9.4.1, que soluciona el problema. En estas versiones, se han agregado las siguientes protecciones: * Los usuarios ya no pueden cargar archivos a un configSet que podría ejecutarse a través de un ClassLoader de Java. * La API de copia de seguridad restringe el almacenamiento de copias de seguridad en directorios que se utilizan en ClassLoader."
