Preparation to do penetration test


  • Collect as much as possible of the target website. For example, port, real IP.
  1. whois : to show the details of the website, like owner, registration information.
  2. www.tianyancha.com. Find the register and other information
  3. www.beianbeian.com
  4. google dork or google hacking: like site: syr.edu. inurl: ?id=123
  5. subdomainBrute . 
  6. https://phpinfo.me/domain find subdomain
  7. site: google.com. Find the subdomain
  8. https://dnsdumpster.com/ find the network of the domain. 
Sometimes if we ping the URI, we only get the CDN server's IP, CDN is for cache static page and improve user experience. So we can ping target IP from different areas through www.17ce.com. If they are the same, we can conclude that there is no CDN server.
https://asm.ca.com/en/ping.php to find the real IP in US.
  • Find the open port:
  1. Nmap, Masscan, Zmap
  2. samba : SMB (server message block) network protocol.

We can check the vulnerability. user=*)(& password=*)(& --> (&(user=*)(&)(password=*)(&))  After we type it, we found the response shows successful, and return a page has search box. Then we type a character in the search box, and it returns some user phonebook information. I tried 'flag', 'HTB', it doesn't find any results.

0x00 Problem 0x01 Check the Source Code We open the website and only see the source code on the website. As we can see, there is a WAF will filter some characters and words, that means the normal injection will not work. However, we can see, there is a json_decode() function will decode JSON data, that means the data can be accepted should be JSON format.  The example JSON format data is like: /u0074, /u0075. In addition, there is a "php://input",  accesses the read-only stream of the requested raw data, executing the data in the post request as PHP code. 0x02 Local Test We can launch an Apache server to test it. I copy the source code and make a little change to test this. This file is in /var/www/html. We will construct the data first. This time I use 'select' as an example. The word transfer to ASCII, then to hex, then replace the '\0x' as '\u00'. This can be test in the browser console. At the end, we can test it with curl . As we can see, the SQL...
