Unauthenticated administrator creation via continued filter chain
Published Mar 24, 2025 · Updated Mar 24, 2025
Improper access control in Mingyuefusu Library Management System allows remote attackers to add administrators without authentication. AdminFilter.doFilter writes a login redirect when the session lacks the admin attribute but still invokes chain.doFilter instead of returning. A network request without an administrator session therefore continues to protected backend handlers, including the administrator-add endpoint.
