Overview

Developers consistently implement sporadic, ad-hoc input validation mechanisms for web applications. Lack of a centralized and well-defined input validation mechanism opens the application to a variety of attacks: including SQL Injection, Cross Site Scripting (XSS), and Command Injection. The OWASP Stinger Project aims to develop a centralized input validation component which can be easily applied to existing or developmental applications. Using a declarative security model, Stinger has the ability to validate all HTTP requests coming into an application. Stinger is such a simplistic yet strong validation engine that organizations have begun integrating it into their software development life-cycle.

Stinger 2.4 Released - 13:58, 21 May 2007 (EDT)

The OWASP Stinger Project is proud to release Stinger 2.4. As noted in RC1, this release is intended to address code quality issues as well as implement several community suggested updates. The following is a list of notable changes:

  • Backported the Stinger 3.0 "DROP/CONTINUE/PROCESS" doAction() logic. No need for "BreakChainException"
  • Cleaned up some code quality issues (removed all instances of System.out and printStackTrace, using interfaces properly, fixed synchronization issues)
  • Added the ability to define an "exclude" list which searches for patterns within a pattern. For example, if we allow the character '.' and the character '/', we may want to prevent instances of '../'. This can now be done by adding an "<exclude>../</exclude>" tag underneath the "<regex></regex>" element of a rule. See the example "stinger.xml" file included with the Stinger Eclipse project for more information.
  • Modified the Log action to hashsession ID's before logging them as well as fixed "getHandler()" property default bug
  • The inclusion of the "exclude-set" value which tells Stinger to do nothing with these pages. Useful for patterns that cover too much (ex. *.*)
  • The stinger.xml file is expected to be found relative to /WEB-INF. This means that we simply set the filter-init "config" parameter to "stinger.xml" rather than "C:\Documents and Settings....\WEB-INF\stinger.xml"
  • Removed the "DisplayMessage" action as it is not very useful
  • Added better logging throughout the code base

Stinger 2.4 RC1 Released - 11:40, 29 January 2007 (EST)

The OWASP Stinger Project is proud to release Stinger 2.4 RC1. This release is largely intended to address some code quality issues.

The following is a list of notable changes:

  • We now allow for an "exclude" option for each parameter. After defining a regular expression for a parameter, we can now define strings that should *NOT* exist within the input. For example, let us assume our regular expression accepts all numbers, characters, a period, and a slash (/). However, note that "aaa../../etc/passwd" would be considered a valid input. Therefore, we can specify an "exclude" tag to prevent such input:
...
<rule>
   <name>file</name>
   <regex>filetext</regex>
   <exclude>../</exclude>
...
  • The "invalidate" action will properly clear the cookie from the user's browser.

The current list of tasks to complete is as follows:

  • Remove the absolute path dependence when specifying the Stinger configuration file in web.xml

As always, let me know if you have any suggestions for improving the Stinger 2.4 release!
