Path traversal vulnerabilities in DSpace JSPUI submission upload

DSpace open source software is a repository application which provides durable access to digital resources. dspace-jspui is a UI component for DSpace. The JSPUI resumable upload implementations in SubmissionController and FileUploadRequest are vulnerable to multiple path traversal attacks, allowing an attacker to create files/directories anywhere on the server writable by the Tomcat/DSpace user, by modifying some request parameters during submission. This path traversal can only be executed by a user with special privileges (submitter rights). This vulnerability only impacts the JSPUI. Users are advised to upgrade. There are no known workarounds. However, this vulnerability cannot be exploited by an anonymous user or a basic user. The user must first have submitter privileges to at least one Collection and be able to determine how to modify the request parameters to exploit the 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SubmissionController 和 FileUploadRequest 中的 JSPUI允许攻击者通过在提交期间修改一些请求参数，在服务器上任何位置创建 Tomcat/DSpace 用户可写的文件或目录。
