DSpace open source software is a repository application which provides durable access to digital resources. Prior to versions 7.6.7, 8.4, 9.3, and 10.0, when ingesting an aggregated ORE resource by URI (using the OAI-ORE Harvester), the ORE Ingestion Crosswalk does not validate the URI scheme. This may allow for local file inclusion via malicious paths like file:///etc/passwd. The attacker MUST already have DSpace collection administrator privileges in order to perform the attack. This issue has been patched in versions 7.6.7, 8.4, 9.3, and 10.0.
