> DESCRIPTION

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, the Curation Task feature allows an output path to be used by the reporter (-r parameter), typically used to stream results and status of curation task operations. It is not restricted to any particular base path, meaning that any path writable by the DSpace (often 'tomcat') user is allowed. This constitutes a Path Traversal Vulnerability in the curate script. This issue has been patched in versions 7.6.7, 8.4, 9.3, and 10.0.
