Technical details
A path traversal vulnerability exists in the ServeStaticFileController::serveFromUserfiles() method of Microweber CMS. The vulnerability stems from the controller accessing the 'path' property from the request object, which can be overridden by a query parameter, rather than using the intended route segment. Because the normalize_path() function fails to adequately strip directory traversal sequences (e.g., '../'), an unauthenticated attacker can craft a GET request to /userfiles/ with a malicious path parameter to read arbitrary files. This can result in the disclosure of sensitive system files like /etc/passwd or application configuration files like .env, which contain database credentials and application keys. A patch has been proposed in pull request #1181 to use realpath() for canonicalization and verify that the resolved path remains within the intended directory.
