CVE-2020-29446Network attack vector

Unauthenticated local-file disclosure via WEB-INF traversal

Published Jan 18, 2021 · Updated Sep 17, 2024

Path traversal in Atlassian FishEye and Crucible before 4.8.5 allows remote attackers to read local files through WEB-INF requests. The vendor identifies the WEB-INF request path as the vulnerable locus but does not disclose the endpoint or failed authorization operation. No authentication or user interaction is required, and the documented impact is limited to local-file disclosure.
