Arbitrary file write via traversed template path
Published Sep 11, 2024 · Updated Sep 12, 2024
Path traversal in Heyewei JFinalCMS 20240903 and earlier allows remote authenticated users to write arbitrary server files. TemplateController.update accepts an unvalidated fileName and content, then passes both to TemplateUtils.write without confining the destination path. Administrative template access is required; the published proof of concept installs an SSH public key and gains server access.
