1, HPP http parameter Pollution http parameter pollution means that the server side usually does some processing when submitting two parameters of the same key value in the URL. For example, Apache is going to take the last argument, for example: user.php?id=111id=222 If you output a $_get array, the ID's value will only take 222, i.e. the extra value submitted on the URL overrides the previous value. 2, a CTF topic http://drops.wooyun.org/tips/17248 About the injected WAF

Shellcode The first example of learning.The following is a command-line program written in C that examines the numbers entered by the user and determines whether they are legitimate. Here the user's input is placed in the function buffer, but the program does not check the length of the buffer, leaving a loophole. This can be used to bypass the digital prosecution, so that any input will be judged to be correct.In validate_serial , the address of theD

Network security platform vendors often need to use a special technology, that is, Bypass. So what is Bypass and how is the Bypass device implemented? Next I will give a brief introduction and description of the Bypass technology. 1. What is Bypass. As you know, network secu

Waf xss bypass posture Due to the wide use of application firewalls, it is necessary to test WAF's ability to defend against xss attacks. Of course, all the experiments are to prove that the vendor must eliminate the vulnerability from the root cause, and cannot lie on the WAF without any worries.Some popular WAF such as F5 Big IP, Imperva Incapsula, AQTRONIX WebKnight, PHP-IDS, Mod-Security, Sucuri, QuickDefense, and Barracuda WAF are all tested.
