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 acept\u00f3 la carga de archivos jar y de clase de Java a trav\u00e9s de la API de ConfigSets. Al realizar una copia de seguridad de las colecciones de Solr, estos archivos de configuraci\u00f3n se guardar\u00e1n en el disco cuando se utilice LocalFileSystemRepository (el valor predeterminado para las copias de seguridad). Si la copia de seguridad se guard\u00f3 en un directorio que Solr usa en su ClassPath/ClassLoaders, entonces los archivos jar y de clase estar\u00edan disponibles para usar con cualquier ConfigSet, confiable o no confiable. Cuando Solr se ejecuta de forma segura (autorizaci\u00f3n habilitada), como se sugiere encarecidamente, esta vulnerabilidad se limita a ampliar los permisos de copia de seguridad con la capacidad de agregar librer\u00edas. Se recomienda a los usuarios actualizar a la versi\u00f3n 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 podr\u00eda ejecutarse a trav\u00e9s 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."}], "lastModified": "2024-02-15T18:40:48.837", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:apache:solr:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "21D17629-7025-4DB8-936C-2C074AC00515", "versionEndExcluding": "8.11.3", "versionStartIncluding": "6.0.0"}, {"criteria": "cpe:2.3:a:apache:solr:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "05682843-ACA2-430C-8BAE-292DD1E9C59E", "versionEndExcluding": "9.4.1", "versionStartIncluding": "9.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security@apache.org"}
