Overview

Most web application platforms do not include features to validate user input. This leaves many organizations to craft their own validation mechanisms, often incomplete, flawed, and inefficient.

The OWASP Validation Project was created to provide guidance and tools related to validation. Our philosophy is that validation is required for every part of the HTTP request, including headers, query string, cookies, form fields, and hidden fields.

Currently, there are several projects underway to create validation technologies for various platforms. The long term goal is to provide a detailed guide for implementing proper input validation as well as provide validation engines for popular web application environments.

The OWASP Validation Project was created by Jeff Williams and is currently maintained by Eric Sheridan.

News

OWASP Stinger Gets a Project Page! - 09:30, 16 December 2006 (EST)

The OWASP Stinger Project has it's own project page. All information pertaining to Stinger (including downloads) can now be found here.

Project Roadmap

The three major goals of the OWASP Validation Project are the following:

  1. build an input validation guide
  2. provide and implement input validation mechanisms for various platforms
  3. rewrite Stinger to incorporate the design principles in the guide

The OWASP Validation Roadmap contains the latest information as to project goals and targeted release dates.

Guide to Building Input Validation

One of the major goals of the OWASP Validation Project is to provide clear and detailed documentation on building input validation mechanisms for your web application needs. In the near future, this section will contain such documentation. Check back soon!

Implementation

The second major goal of the OWASP Validation Project is to provide input validation mechanisms which adhere to one or more of the design principles outlined in the 'Input Validation Guide'. If you have a project which fits this requirement, please submit it via email to the project lead.

OWASP Validation Documentation

The primary purpose of the OWASP Validation Documentation project is to provide the design principles necessary to build an effective input validation engine. More can be found here.

Java

The Stinger library is a full J2EE Validation Engine which strongly adheres to the principle's outline in the Validation Documentation. More information can be found on the Stinger Project page at http://www.owasp.org/index.php/OWASP_Stinger_Project

Most modern Java web frameworks include their own data validation features. All of these can validate user data in GET and POST requests, but usually do not validate cookie data. Web frameworks that provide their own validation features include:

.NET

One of the goals of the OWASP Validation Project is to implement Stinger 2.0 on the .NET platform.

If you are interested in leading this project, please contact Eric Sheridan.

Please refer to the project road map for an estimated time of arrival.

PHP

The PHP Filters Project provides an API framework for validating input for various purposes. The project can be found here.

OWASP Recently released the OWASP Top 5, an article illustrating several attack vectors against PHP applications.

The majority of the PHP Top 5 can be alleviated with a solid and well defined validation mechanism.

RegEx Repository

The OWASP RegEx Repository contains a multitude of regular expressions for common data types. Developers implementing input validation engines should review these regular expressions. Save the time of developing a complicated regular expression that currently exists!
