== What is XSS
NEED DEFINITION.
Cross-site script (also commonly known as XSS) is a vulnerability/flaw that combines ...
# the allowance of html/script tags as input that are ...
# rendred into a browser without encoding or sanitization
==== Cross site scripting (XSS) is the most prevalent and pernicious web application security issue
=== Cross site scripting (XSS) is the most prevalent and pernicious web application security issue
==== XSS flaws occur whenever an application takes user originated data and sends it to a web browser without validation or encoding
While there is a simple well-known defense for this attack, there are still many instances of it on the web. In terms of fixing it,
coverage of fixes also tends to be a problem. We'll talk more about the defense in a little bit.
=== XSS allows attackers to execute script in the victim’s browser and take over the user’s browser using scripting malware
=== XSS has a significant impact
==== Examples:
Especially as 'Rich Internet Applications' are more and more common place, privileged function calls linked to via javascript may be compromised.
And if not properly protected, sensitive data (such as your authentication cookies) can be stolen and used for someone else's purpose.
==== Quick examples:
* From the browser address bar (chrome, Firefox)

Type in `javascript:alert(document.cookie);` in the URL bar. *NOTE:* If you /cut/paste you'll need to add the `javascript:` back in.

Identify which field is susceptible to XSS
It is always a good practice to validate all input on the server side. XSS can occur when unvalidated user input is used in an HTTP response. In a reflected XSS attack, an attacker can craft a URL with the attack script and post it to another website, email it, or otherwise get a victim to click on it.

== DOM-Based XSS Scenario
DOM-based XSS is similar to reflected. The difference is that the payload will never go to the server, but will only ever be processed by the client.
* Attacker sends a malicious URL to victim
* Victim clicks on the link that loads malicious web page
* The malicious web page's JavaScript opens a local web page on the victims machine that contains an attack
* The local page executes attack in the computer’s local zone
* Victim clicks on the link
* That link may load a malicious web page or a web page they use (are logged into?) that has a vulnerable route/handler
* If it's a malicious web page, it may use it's own JavaScript to attack another page/url with a vulnerable route/handler
* The vulnerable page renders the payload and executes attack in the user's context on that page/site
* Attacker’s malicious script may run commands with the privileges of local account
*Victim does not realize attack occurred*
*Victim does not realize attack occurred* ... Malicious attackers don't use &lt;script&gt;alert('xss')&lt;/ script&gt;

== Try It! DOM-Based XSS
Need A Lesson
For this, you'll want to look for some 'test' code in the route handlers (javascript/backbone). Sometimes, test code gets left in.
(Often times test code is very simple and lacks security or any quality controls!).
Your objective is to find the route and exploit it. First though ... what is the base route? As an example, look at the URL for this lesson ...
it should look something like /WebGoat/start.mvc#lesson/CrossSiteScripting.lesson/5 (although maybe slightly different). The 'base route' in this case is:
*start.mvc#lesson/*
The *CrossSiteScripting.lesson/5* after that are parameters that are processed by javascript route handler.
So, what is test route for this test code?

#StringSqlInjection.java
StringSqlInjectionSecondStage=Now that you have successfully performed an SQL injection, try the same type of attack on a parameterized query. Restart the lesson if you wish to return to the injectable query.
EnterLastName=Enter your last name:
NoResultsMatched=No results matched. Try Again.
SqlStringInjectionHint1=The application is taking your input and inserting it at the end of a pre-formed SQL command.
SqlStringInjectionHint2=This is the code for the query being built and issued by WebGoat:<br><br> "SELECT * FROM user_data WHERE last_name = "accountName"
SqlStringInjectionHint3=Compound SQL statements can be made by joining multiple tests with keywords like AND and OR. Try appending a SQL statement that always resolves to true
SqlStringInjectionHint4=Try entering [ smith' OR '1' = '1 ].
# XSS success, failure messages and hints
xss-reflected-5a-success=well done, but alerts aren't very impressive are they? Please continue.
xss-reflected-5a-failure=Try again. We do want to see this specific javascript (in case you are trying to do something more fancy)
xss-reflected-5b-success=Correct ... because <ul><li>The script was not triggered by the URL/QueryString</li><li>Even if you use the attack URL in a new tab, it won't execute (becuase of response type). Try it if you like.</li></ul>
xss-reflected-5b-failure=Nope, pretty easy to guess now though.
xss-reflected-6a-success=Correct! Now, see if you can send in an exploit to that route in the next assignment.
xss-reflected-6a-failure=No, look at the example. Check the GoatRouter.js file. It should be pretty easy to determine.
xss.lesson1.failure=Are you sure? Try using a tab from a different site.
xss.lesson1.failure=Are you sure? Try using a tab from a different site.
#xss-reflected-5b-do5a-first=Do the reflected xss attack prior to this, then come back and answer this.
