CVE-2022-31194Network attack vector

Arbitrary file write via unchecked upload paths

Published Aug 1, 2022 · Updated Apr 23, 2025

Path traversal in DSpace JSPUI 4.0 through 5.10 and 6.0 through 6.3 allows remote authenticated users to write server-side files. SubmissionController and FileUploadRequest append attacker-controlled upload identifiers, chunk numbers, and filenames to the temporary directory without validating the resulting canonical paths. Submitter rights to at least one Collection are required, and writes are limited to locations writable by the Tomcat/DSpace account.
