Welcome to Release 5.1, a security and bug-fix release for the DSpace 5.x platform. For information on upgrading to DSpace 5, please see Upgrading DSpace.
5.1 Release Notes

DSpace 5.1 contains security fixes for both the XMLUI and JSPUI. To ensure your 5.x site is secure, we highly recommend all DSpace 5.x users upgrade to DSpace 5.1. We also highly recommend removing any "allowLinking=true" settings from your Tomcat <Context> settings. Previously our installation documentation erroneous listed added "allowLinking=true", while the Tomcat documentation lists it as a possible security concern. The XMLUI Directory Traversal Vulnerability (see below) was also exacerbated by this setting. |

Several of the security vulnerabilities patched in DSpace 5.1 (and backported to 4.3 and 3.4) also affect sites running unsupported DSpace 1.x releases. In order to ensure your site is patched, we highly recommend upgrading to DSpace 3.4, DSpace 4.3 or DSpace 5.1. If you are considering an upgrade from DSpace 1.x, note that, as of DSpace 5, your existing data (i.e. database contents, search/browse indexes) will now be automatically upgraded from ANY prior version of DSpace. Therefore, you may wish to consider upgrading directly to DSpace 5.1, as the 5.x upgrade process is simplified. |
DSpace 5.1 is a security and bug fix release to resolve several issues located in DSpace 5.0. As it only provides only bug fixes, DSpace 5.1 should constitute an easy upgrade from DSpace 5.0 for most users. No database changes or additional configuration changes should be necessary when upgrading from DSpace 5.0 to 5.1.
This release addresses the following security issues discovered in DSpace 5.x and below:
- XMLUI Security Fixes
HIGH SEVERITY: XMLUI Directory Traversal Vulnerabilities (DS-2445 - requires a JIRA account to access): These vulnerabilities allow a hacker to potentially access any file on your local filesystem which is readable to the Tomcat user account. This includes files which are unrelated to DSpace or Tomcat, but are readable to all users on the filesystem (e.g. /etc/passwd, /etc/hosts, etc.). This vulnerability has existed since DSpace 1.5.2.
Discovered by: Khalil Shreateh, with additional (related) vulnerabilities discovered by the DSpace Committer Team
- We also highly recommend immediately removing any "allowLinking=true" settings from your Tomcat <Context>s. For most configurations, this provides a "quick fix" to the most severe directory traversal vulnerability, and the Tomcat documentation lists it as a possible security concern. However, you still must upgrade or patch your DSpace in order to completely patch your DSpace.
- JSPUI Security Fixes
- MEDIUM SEVERITY: JSPUI Directory Traversal Vulnerability (DS-2448 - requires a JIRA account to access): This vulnerability allows a hacker to potentially access any file within the JSPUI web application directory (e.g. WEB-INF/web.xml). This vulnerability is believed to have existed in all prior versions of DSpace.

- LOW SEVERITY: Cross-site scripting (XSS injection) is possible in JSPUI Recent Submissions listings (DS-1702 - requires a JIRA account to access): This potential vulnerability could allow a depositor/submitter to embed javascript code into the metadata of a new submission, thus causing that code to be run across other user accounts. However, this vulnerability is only possible by someone with privileges to add content to your DSpace site. This vulnerability has existed since DSpace 1.5.x.

- LOW SEVERITY: Cross-site scripting (XSS injection) is possible in JSPUI Discovery search form (DS-2044 - requires a JIRA account to access): This potential vulnerability could allow someone searching your site to embed HTML or Javascript into the JSPUI search form, causing it to run in their own browser. However, as those searches are not saved, they would not be run across other user accounts. This vulnerability has existed since DSpace 3.x
- 4.x / 5.x vulnerability discovered by Gabriela Mircea of McMaster University and Khalil Shreateh
- 3.x vulnerability discovered by İlyas Orak of Biznet Bilisim A.S.
- MEDIUM SEVERITY: JSPUI Directory Traversal Vulnerability (DS-2448 - requires a JIRA account to access): This vulnerability allows a hacker to potentially access any file within the JSPUI web application directory (e.g. WEB-INF/web.xml). This vulnerability is believed to have existed in all prior versions of DSpace.
In addition, this release fixes a variety of minor bugs in the 5.0 release. For more information, see the Changes in 5.x page.
