Recommended response

Check inventory. Check lockfiles and deployed manifests for DSpace/DSpace, org.dspace:dspace-api, org.dspace:dspace-api.
Review the reported fix. Update org.dspace:dspace-api to 8.4; org.dspace:dspace-api to 9.3; org.dspace:dspace-api to 10.0; org.dspace:dspace-api to 8.4; org.dspace:dspace-api to 9.3; org.dspace:dspace-api to 10.0 if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

Upstream source description

DSpace open source software is a repository application which provides durable access to digital resources. From versions 8.0-rc1 to before 8.4, 9.0-rc1 to before 9.3, and 10-rc1 to before 10.0, a path traversal vulnerability is possible via the COAR Notify / LDN service in DSpace. The attacker MUST already have DSpace administrator credentials in order to perform the attack. When reading a file input stream of an "inbound pattern" / "template", used to generate an LDN message, the LDN class does not check for path traversal or restrict the templates to a known base path. This could allow an untrusted file from elsewhere in the file system (e.g. an export log, a bitstream path, a temporary file) to be read and interpreted as an Apache Velocity template. This issue has been patched in versions 8.4, 9.3, and 10.0.
