CVE-2023-34645Public exploitNetwork attack vector

Arbitrary file read via template path traversal

Published Jun 16, 2023 · Updated Dec 17, 2024

Path traversal in jfinal CMS 5.1.0 allows attackers to read arbitrary server files through a crafted template expression. The template engine evaluates a crafted printFile expression and follows repeated parent-directory segments outside the application tree. Template-management access is required to plant the expression; rendering the home page then exposes the selected file's contents, as demonstrated with /etc/passwd.
