DSpace open source software is a repository application which provides durable access to digital resources. dspace-xmlui is a UI component for DSpace. In affected versions metadata on a withdrawn Item is exposed via the XMLUI "mets.xml" object, as long as you know the handle/URL of the withdrawn Item. This vulnerability only impacts the XMLUI. Users are advised to upgrade to version 6.4 or newer.

Affected: Maven: org.dspace:dspace-xmlui

### Impact Metadata on a withdrawn Item is exposed via the XMLUI "mets.xml" object, as long as you know the handle/URL of the withdrawn Item. This vulnerability only impacts the XMLUI.

However, this vulnerability is very low severity as Item metadata does not tend to contain highly secure or sensitive information.

_This vulnerability does NOT impact the JSPUI or 7.x._

### Patches

Because of the low severity of this security issue, it requires updating to 6.4 to resolve. _No patch is available for 5.x or below._

_DSpace 6.x:_ * Fixed in 6.4 via #2451 * 6.x patch file: https://github.com/DSpace/DSpace/commit/574e25496a40173653ae7d0a49a19ed8e3458606.patch (may be applied manually if an immediate upgrade to 6.4 or above is not possible)

#### Apply the patch to your DSpace If at all possible, we recommend upgrading your DSpace site based on the upgrade instructions. However, if you are unable to do so, you can manually apply the above patches as follows: 1. Download the appropriate patch file to the machine where DSpace is running 2. From the `[dspace-src]` folder, apply the patch, e.g. `git apply [name-of-file].patch` 3. Now, update your DSpace site (based loosely on the Upgrade instructions). This generally involves three steps: 1. Rebuild DSpace, e.g. `mvn -U clean package` (This will recompile all DSpace code) 2. Redeploy DSpace, e.g. `ant update` (This will copy all updated WARs / configs to your installation directory). Depending on your setup you also may…
