Reino: Input Validation and Representation

Los problemas de validación y representación de entradas están causados por metacaracteres, codificaciones alternativas y representaciones numéricas. Los problemas de seguridad surgen de entradas en las que se confía. Estos problemas incluyen: «desbordamientos de búfer», ataques de «scripts de sitios», "SQL injection" y muchas otras acciones.

OGNL Expression Injection: Dynamic Method Invocation

Java/JSP

Abstract

La aplicación de Struts 2 permite Dynamic Method Invocation, que se sabe que es vulnerable a los ataques de inyección OGNL en algunas versiones de Struts 2.

Explanation

Struts 2 introdujo una característica llamada "Dynamic Method Invocation" que permite que una acción exponga métodos distintos a execute(). El carácter ! (signo de admiración) o el prefijo method: se pueden usar en la dirección URL de la acción para invocar cualquier método público en la acción si "Dynamic Method Invocation" está habilitada. En la versión 2.3.20 de Struts 2 el mecanismo para invocar el método alternativo que anteriormente se basaba en la reflexión, se sustituyó por OGNL, lo que permitía a los atacantes proporcionar expresiones OGNL malintencionadas en lugar de un nombre de método alternativo.
