CVE-2023-42398Network attack vector

Unauthenticated code execution via unrestricted ueditor fetch

Published Sep 15, 2023 · Updated Sep 25, 2024

Server-side request forgery in ZZCMS 2023 allows remote attackers to execute arbitrary code and obtain sensitive data through ueditor. The ueditor controller.php handler dereferences an attacker-controlled resource location without enforcing an allowed destination; the public report does not name the input field. No authentication or user interaction is required, and successful requests can expose internal resources or execute attacker-controlled code.
