datingxd ru - Validating dynaactionform

Students learn how to incorporate JSPs, servlets, EJBs and Java Beans into their design.

Corresponding to every chapter, there is a lab reinforcing the concept. Struts Architecture and Overview * Objectives * Review: MVC Model * Review: Request, Session and Application * What is Struts?

También se puede reutilizar el mismo Action Form en distintos formularios que compartan datos (por ejemplo, para dar de alta o modificar los datos de un usuario registrado).

Veremos también las librerías de etiquetas propias de Struts.

Aunque algunas de ellas han quedado obsoletas tras la aparición de JSTL, otras siguen siendo de utilidad en conjunto con los Action Forms.

String cert_name = ((String)((Dyna Action Form)Form).get("cert Name")).trim(); Integer cert_type = (Integer)((Dyna Action Form)Form).get("cert Type"); Integer key_length = (Integer)((Dyna Action Form)Form).get("key Length"); Integer valid_days = (Integer)((Dyna Action Form)Form).get("valid Days"); String country_code = ((String)((Dyna Action Form)Form).get("country Code")).trim(); String state = ((String)((Dyna Action Form)Form).get("state")).trim(); String locality = ((String)((Dyna Action Form)Form).get("locality")).trim(); String org = ((String)((Dyna Action Form)Form).get("org")).trim(); String org_unit = ((String)((Dyna Action Form)Form).get("org Unit")).trim(); String common_name = ((String)((Dyna Action Form)Form).get("common Name")).trim(); String email_address = ((String)((Dyna Action Form)Form).get("email Address")).trim(); country_code = country_code.replace("\"", ""); country_code = country_code.replace("/", ""); state = state.replace("\"", ""); state = state.replace("/", ""); locality = locality.replace("\"", ""); locality = locality.replace("/", ""); org = org.replace("\"", ""); org = org.replace("/", ""); org_unit = org_unit.replace("\"", ""); org_unit = org_unit.replace("/", ""); common_name = common_name.replace("\"", ""); common_name = common_name.replace("/", ""); email_address = email_address.replace("\"", ""); email_address = email_address.replace("/", ""); // ... if (cert_Value() == 0) Here is the where things going bad.

We managed to identify two different vulnerability during assessment. User supplied variables such as common_name, state etc is being used on command generation without proper validation.

This gets annoying as the Struts Config file grow larger.# The Dyna Action Form is not strongly typed as the Action Form.
