Impact

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 XSS. This vulnerability only impacts the JSPUI.

This vulnerability does NOT impact the XMLUI or 7.x.

Patches

DSpace 6.x:

DSpace 5.x:

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 need to copy the updated WARs over to your Tomcat webapps folder.
    3. Restart Tomcat
