CVE-2024-7927Public exploitNetwork attack vector

Unauthenticated file read via unchecked skin paths

Published Aug 19, 2024 · Updated Aug 20, 2024

Path traversal in ZZCMS 2023 allows remote attackers to read arbitrary server files through the class-management endpoint. The dowhat=modifyclass handler in /admin/class.php accepts attacker-controlled skin[] path elements without validating that the resolved path remains inside the intended directory. No authentication or user interaction is required, and successful requests disclose files accessible to the PHP process.
