Welcome to Release 6.4, a bug-fix release for the DSpace 6.x platform. Any previous version of DSpace may be upgraded to DSpace 6 directly. For more information, please see Upgrading DSpace.

6.4 Release Notes

DSpace 6.4 is a bug fix release to resolve several issues located in previous 6.x releases. As it only provides only bug fixes, DSpace 6.4 should constitute an easy upgrade from DSpace 6.x for most users. No database changes should be necessary when upgrading from DSpace 6.x to 6.4.

Security fixes include:

• [HIGH] CVE-2022-31195 (impacts XMLUI and JSPUI): Path traversal vulnerability in Simple Archive Format package import (ItemImportService API). 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. This path traversal is only possible by a user with special privileges (Administrators or someone with command-line access to the server).
  • Reported by Johannes Moritz of Ripstech
• [HIGH] CVE-2022-31194 (impacts JSPUI only) : 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, just by modifying some request parameters during submission. This path traversal can only be executed by a user with submitter rights.
  • Reported by Johannes Moritz of Ripstech
• [HIGH] CVE-2022-31193 (impacts JSPUI only) : The JSPUI controlled vocabulary servlet is vulnerable to an open redirect attack, where an attacker can craft a malicious URL that looks like a legitimate DSpace/repository URL. When that URL is clicked by the target, it redirects them to a site of the attacker's choice.
  • Reported by Johannes Moritz of Ripstech
• [MODERATE] CVE-2022-31191 (impacts JSPUI only) : The JSPUI spellcheck "Did you mean" HTML escapes the data-spell attribute in the link, but not the actual displayed text. Similarly, the JSPUI autocomplete HTML does not properly escape text passed to it. Both are vulnerable to Cross Site Scripting (XSS).
  • Reported by Hassan Bhuiyan, Brunel University London
• [MODERATE] CVE-2022-31192 (impacts JSPUI only) : The JSPUI "Request a Copy" feature is vulnerable to Cross Site Scripting (XSS) attacks.
  • Reported by Andrea Bollini of 4Science
• [LOW] CVE-2022-31189 (impacts JSPUI only) When an "Internal System Error" occurs in the JSPUI, then entire exception (including stack trace) is available. Information in this stacktrace may be useful to an attacker in launching a more sophisticated attack.
  • Reported by Johannes Moritz of Ripstech
• [LOW] CVE-2022-31190 (impacts XMLUI only) Metadata of withdrawn Items is exposed to anonymous users in XMLUI.
  • Reported by David Cavrenne of Atmire

6.3 Release Notes

DSpace 6.3 is a bug fix release to resolve several issues located in previous 6.x releases. As it only provides only bug fixes, DSpace 6.3 should constitute an easy upgrade from DSpace 6.x for most users. No database changes should be necessary when upgrading from DSpace 6.x to 6.3. One configuration addition (orcid.api.url property) has been made to the default dspace.cfg to support the new ORCID API v2, for ORCID Authority Control users.

JSPUI security fixes include

• [HIGH SEVERITY] A user can inject malicious Javascript into the names of EPeople or Groups. This is most severe in sites which allow anyone to register for a new account. (https://jira.duraspace.org/browse/DS-3866 - requires a JIRA account to access.) 

  • Reported by Julio Brafman

• [MEDIUM SEVERITY] Any user was able to export metadata to CSV format if they knew the correct JSPUI path/parameters. Additionally, the exported CSV included metadata fields which are flagged as hidden in configuration. (https://jira.duraspace.org/browse/DS-3840 - requires a JIRA account to access.)

    • Note: This issue was limited to 6.0, 6.1 or 6.2, and specifically ONLY occurred when Item Level Versioning was first enabled on DSpace version 4.x or 5.x (and that old versioning data had since been migrated to 6.x).

We offer thanks to those institutions for supporting their staff to take time to contribute to the DSpace project.

A big thank you also goes out to the DSpace Community Advisory Team (DCAT), who helped the developers to prioritize and plan out several of the new features that made it into this release. The current DCAT members include: Augustine Gitonga, Bram Luyten, Bharat Chaudhari, Claire Bundy, Dibyendra Hyoju, Elin Stangeland, Felicity A Dykas, Iryna Kuchma, James Evans, Jim Ottaviani, Kate Dohe, Kathleen Schweitzberger, Leonie Hayes, Lilly Li, Maureen Walsh, Pauline Ward, Roger Weaver, Sarah Molloy, Sarah Potvin, Steve Van Tuyl, Terry Brady, Yan Han and Valorie Hollister.

We apologize to any contributor accidentally left off this list. DSpace has such a large, active development community that we sometimes lose track of all our contributors. Our ongoing list of all known people/institutions that have contributed to DSpace software can be found on our DSpace Contributors page. Acknowledgments to those left off will be made in future releases.

Want to see your name appear in our list of contributors? All you have to do is report an issue, fix a bug, improve our documentation or help us determine the necessary requirements for a new feature! Visit our Issue Tracker to report a bug, or join dspace-devel mailing list to take part in development work. If you'd like to help improve our current documentation, please get in touch with one of our Committers with your ideas. You don't even need to be a developer! Repository managers can also get involved by volunteering to join the DSpace Community Advisory Team and helping our developers to plan new features.

The Release Team consisted of:

• Tim Donohue (DuraSpace)
• Kevin Van de Velde (@mire)
  
• Pascal-Nicolas Becker (Technische Universität Berlin)

Additional thanks to Tim Donohue from DuraSpace for keeping all of us focused on the work at hand, for calming us when we got excited, and for the general support for the DSpace project.
