Detailsinfo

A vulnerability has been found in DSpace (affected version unknown) and classified as critical. Affected by this vulnerability is an unknown functionality of the component ItemImportServiceImpl. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was published 08/02/2022 as GHSA-8rmh-55h4-93h5. The advisory is shared at github.com. This vulnerability is known as CVE-2022-31195 since 05/18/2022. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1006 for this issue.
