Authenticated phishing redirect via unvalidated ret parameter
Published May 17, 2025 · Updated May 19, 2025
Open redirect in kanwangzjm Funiture allows remote authenticated users to send browsers to attacker-controlled sites. The LoginServlet.doPost method passes the unvalidated ret request parameter directly to HttpServletResponse.sendRedirect after a successful login. Valid credentials and user interaction with a crafted login request are required; the redirect enables phishing but does not alter server data.
