In affected versions the ItemImportServiceImpl is vulnerable to a path traversal vulnerability. This means a malicious SAF (simple archive format) package could cause a file/directory to be created anywhere the Tomcat/DSpace user can write to on the server. However, this path traversal vulnerability is only possible by a user with special privileges (either Administrators or someone with command-line access to the server). This vulnerability impacts the XMLUI, JSPUI and command-line. Users are advised to upgrade. As a basic workaround, users may block all access to the following URL paths: If you are using the XMLUI, block all access to /admin/batchimport path (this is the URL of the Admin Batch Import tool). Keep in mind, if your site uses the path \"/xmlui\", then you'd need to block access to /xmlui/admin/batchimport. If you are using the JSPUI, block all access to /dspace-admin/batchimport path (this is the URL of the Admin Batch Import tool). Keep in mind, if your site uses the path \"/jspui\", then you'd need to block access to /jspui/dspace-admin/batchimport. Keep in mind, only an Administrative user or a user with command-line access to the server is able to import/upload SAF packages. Therefore, assuming those users do not blindly upload untrusted SAF packages, then it is unlikely your site could be impacted by this vulnerability."}, {"lang": "es", "value": "El software de c\u00f3digo abierto DSpace es una aplicaci\u00f3n de repositorio que proporciona acceso duradero a los recursos digitales. En las versiones afectadas el ItemImportServiceImpl es vulnerable a una vulnerabilidad de salto de ruta. Esto significa que un paquete SAF (formato de archivo simple) malicioso podr\u00eda causar la creaci\u00f3n de un archivo/directorio en cualquier lugar donde el usuario de Tomcat/DSpace pueda escribir en el servidor. Sin embargo, esta vulnerabilidad de salto de ruta s\u00f3lo es posible por un usuario con privilegios especiales (ya sea administradores o alguien con acceso a la l\u00ednea de comandos del servidor). Esta vulnerabilidad afecta a XMLUI, JSPUI y a la l\u00ednea de comandos. Es recomendado a usuarios actualizar. Como mitigaci\u00f3n b\u00e1sica, los usuarios pueden bloquear todo el acceso a las siguientes rutas URL: Si usa la XMLUI, bloquee todos los accesos a la ruta /admin/batchimport (esta es la URL de la herramienta Admin Batch Import). Ten en cuenta que si tu sitio usa la ruta \"/xmlui\", tendr\u00e1s que bloquear el acceso a /xmlui/admin/batchimport. Si usas la JSPUI, bloquea todo el acceso a la ruta /dspace-admin/batchimport (esta es la URL de la herramienta Admin Batch Import). Ten en cuenta que si tu sitio usa la ruta \"/jspui\", entonces tendr\u00e1s que bloquear el acceso a /jspui/dspace-admin/batchimport. Tenga en cuenta que s\u00f3lo un usuario administrativo o un usuario con acceso a la l\u00ednea de comandos del servidor puede importar/cargar paquetes SAF. Por lo tanto, asumiendo que esos usuarios no suben ciegamente paquetes SAF no confiables, entonces es poco probable que su sitio pueda ser impactado por esta vulnerabilidad"}], "lastModified": "2022-08-08T17:16:12.553", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:duraspace:dspace:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D0931332-ACDA-450E-BDC7-BE5D44E27F66", "versionEndIncluding": "5.10", "versionStartIncluding": "4.0"}, {"criteria": "cpe:2.3:a:duraspace:dspace:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "27C1503E-2C8B-43CD-8937-9ABE6C24C67F", "versionEndExcluding": "6.4", "versionStartExcluding": "6.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
