CVE-2022-31195 Information

Description

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.
