CVE-2022-39367Network attack vector

Arbitrary file writes via unsanitized ZIP paths

Published Oct 28, 2022 · Updated Apr 22, 2025

Path traversal in QTIWorks before 1.0-beta15 allows remote authenticated users to write outside the import directory via crafted ZIP entries. AssessmentPackageFileImporter joins each untrusted entry name to the import sandbox path and writes it without checking that the normalized destination remains inside that sandbox. Default deployments require instructor privileges to upload packages; enabling the public demo exposes arbitrary writable-file modification to unauthenticated attackers.
