Kingdom: Input Validation and Representation
Input validation and representation problems ares caused by metacharacters, alternate encodings and numeric representations. Security problems result from trusting input. The issues include: "Buffer Overflows," "Cross-Site Scripting" attacks, "SQL Injection," and many others.
Struts: Form Field Without Validator
Abstract
Every field in a form should be validated in the corresponding validation form.
Explanation
Omitting validation for even a single input field can allow attackers the leeway they need.
Unchecked input is the root cause of some of today's worst and most common software security problems. Cross-site scripting, SQL injection, and process control vulnerabilities all stem from incomplete or absent input validation. Although J2EE applications are not generally susceptible to memory corruption attacks, if a J2EE application interfaces with native code that does not perform array bounds checking, an attacker may be able to use an input validation mistake in the J2EE application to launch a buffer overflow attack.

ActionForm for more than one purpose. In situations such as this, some fields may go unused under some action mappings. It is critical that unused fields be validated too. Preferably, unused fields should be constrained so that they can only be empty or undefined. If unused fields are not validated, shared business logic in an action could allow attackers to bypass the validation checks that are performed for other uses of the form.References
