OWASP Security Shepherd Project - Session Management Challenge 8 (Session Management Challenge)

Challenge

Solution

    Click the Privileged User Only Button ->

      Check Burp for packet send ->
There is an adminDetected parameter sent & a challengeRole cookie added.

    Try making the adminDetected as true ->
We could now pretty much sure that they use challengeRole as a check method for admin.

    Bad news is we have no idea what is LmH6nmbC. By trying out the decoders online, we will notice that ATOM-128 decryption of LmH6nmbC is guest!

    Let's use admin's ATOM-128 encryption -> KiA9MiNC.
We will get a response <!-- Invalid Role Detected -->

    We must find another user account which is valid. It turns out that the answer is superuser -> nmHqLjQknlHs.

OSCP回顧 & 準備建議

緣起         去年, 2017年, 我完成了一趟學習上的奇妙旅程, 獲得了OSCP認證. 一開始很擔心自己的程度是不是足夠? 能不能花足夠多的時間在學習與練習? 幸運的是家人、朋友們都很支持我, 使我能在最後通過了長達24小時的認證考試.         寫這篇文章, 一方面是因為想回顧一下自己的學習歷程, 另一方面是我發現很少有中文的Review去介紹和給與準備考OSCP的人們一些建議, 所以希望由我自己開始, 為想要學習資訊安全的人們提供一個起始點 : -) Offensive Security & OSCP         Offensive Security是一家享譽業界的認證機構，其中最為人所知的便是Offensive Security是Kali Linux的製作與維護團隊。OSCP則是Offensive Security的旗艦級認證，可以說是講到Offensive Security就會想到OSCP。         OSCP因為它的考試是以24小時，獨立突破5台機器的實做模式聞名，也因此廣泛的被業界認可。擁有這張證照的成員，一般被認為有能力可以獨立進行滲透測試。 OSCP: https://www.offensive-security.com/information-security-certifications/oscp-offensive-security-certified-professional/ PWK(OSCP training course): https://www.offensive-security.com/information-security-training/penetration-testing-training-kali-linux/ 報名OSCP的資格         很多人會疑惑說，什麼樣的人有資格去報名OSCP課程？我是不是準備好了？甚至有網路...

Challenge Solution     First step, let's try to input Mary Martin .     Then, let's try 1'or'1'='1 .     Well, maybe that's because 1 isn't a valid character for Name? Let's try a'or'a'='a .     Not bad, we get the user list. However, our purpose is to get credit card number. We must try to UNION SELECT the credit card number field!     The first thing comes to my mind is how can I get the table name and column names of this application database.     Try ' UNION SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE '1'='1 =>     Try ' UNION SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='customer =>     Now, we are sure that the application doesn't have the privilege to access information_schema... Try to use GROUP BY to guess column name. Input ' group by name having '1'='1   => An error was detected! com...
