High severity GitHub Reviewed Published Jul 29, 2022 in DSpace/DSpace • Updated Jan 27, 2023

Package

Description

Impact

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.

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

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
