Path traversal vulnerability in Simple Archive Format package import in DSpace

DSpace open source software is a repository application which provides durable access to digital resources. 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.

对路径名的限制不恰当(路径遍历)

DSpace 路径遍历漏洞

DSpace是DuraSpace社区的一个开源的交钥匙存储库应用程序。 DSpace 4.0 到 6.3版本存在路径遍历漏洞，该漏洞源于意 SAF（简单存档格式）包可能会导致在 Tomcat/DSpace 用户可以在服务器上写入的任何位置创建文件/目录。
