Internal network probing via unchecked download URL
Published Jun 9, 2022 · Updated Aug 3, 2024
SSRF in Jizhicms 2.2.5 allows remote attackers to make the server request attacker-chosen URLs through template updates. The update function in app/admin/c/TemplateController.php URL-decodes download_url without validation and passes it to fopen during start-download. The published proof uses a session cookie, while NVD assesses no privileges as required; the server can probe intranet web services.
