Unauthenticated information disclosure via malformed login request
Published Jun 5, 2023 · Updated Jan 8, 2025
Information disclosure in Emoncms 11.0 and later allows remote attackers to read the server's web directory path via a crafted login request. The /user/login.json endpoint accepts an array-form password parameter and returns internal server details instead of rejecting the malformed type. No authentication or user interaction is required, and the demonstrated consequence is limited to disclosure of path and server information.
