CVE-2020-19147Network attack vector

Authenticated file disclosure via getFolder path traversal

Published Sep 15, 2021 · Updated Aug 4, 2024

Path traversal in JFinal CMS 4.7.1 and earlier allows remote authenticated users to read sensitive files through getFolder(). Public records identify modules/filemanager/FileManager.java as the locus, but do not disclose the accepted path parameter or exact missing containment check. A valid low-privilege session and network access to the file-manager function are required; the documented consequence is confidentiality loss only.
