Summary		(es) Múltiples vulnerabilidades de cross-site scripting (XSS) en PaperCut NG/MF anteriores a la versión 25.0.10 permiten a usuarios administradores autenticados inyectar scripts web o código HTML arbitrarios a través de diferentes campos de la interfaz de usuario. Esto podría usarse para comprometer las sesiones de otros administradores o realizar acciones no autorizadas a través del contexto autenticado del administrador (por ejemplo, requiere una sesión de inicio de sesión activa).
