SQL injection, The classical example of web application vulnerabilities. But if you are total newbie to web application hacking, this will be a great starting point to you. In this document we are going to see what is SQL injection and what is happening under the hood. With SQL we can do things like creating, deleting, modifying data tables, Fetching, Inserting data etc. So it asks for username and password.

Then the web application asks the database "Do you have a user with username 'Test' and password is 'cat'. First it get post data and put them directly in a SQL quarry. It does not check what type of data is submitted. Hear is the SQL quarry which is used. So we are going to fuzz the web application. Wait what does mean fuzzing?.

Fuzzing is we give the web application some random data. We know if we want to break a SQL quarry we input an apostrophe ' or a double quote. This time I enter user as the username and pass' as the password. Did you noticed a singe quote after 'pass'.

So the quarry becomes. Due to quote which is we entered after test quarry think our input is over. If there is nothing more the quarry is fine and O. But there is another quote and some other code also after this string.

That caused to throw an error. Is this all thing we wanted. No we want to try break this web-application and bypass the login. For this purpose we want some logic. Think that what if I add this string as the input.

In this quarry all things after -- is ignored. We can only care about part that before Only that part of our quarry is affected. This is the time logic is come to play. If you take care about below par of code you can understand what's happening. The interesting thing about OR operator is it checks two Boolean statements and if one of them or both of them are correct it will return true.

As 1 is always similar to 1 this quarry ignore if password is not correct. So we could bypass the password check.We recently migrated our community to a new web platform and regretably the content for this page needed to be programmatically ported from its previous wiki page.

SQL injection attacks are a type of injection attackin which SQL commands are injected into data-plane input in order to effect the execution of predefined SQL commands. The given example works in case of cleaning of dangerous traffic, not in case of blocking the entire request or the attack source. Example Number 2 of a vulnerability in the function of request Normalization. The given example works in case of excessive cleaning of incoming data replacement of a regular expression with the empty string.

QueryString "id". Negation and inequality signs! An example of various request notations with the same meaning. An example of signature bypass. Some case SQL keyword was filtered out and replaced with whitespace. Which, of course, we can exploit! You can test if the WAF can be crashed by typing:? If you get ayou can exploit it using the Buffer Overflow Method.

So, if you find such a silly function, you can exploit it, in this way. Code: or -' or 1 or '1"or 1 or". Watch Star.

I am just curious why do they include it as a cheat sheet instead? How is that particular cheat sheet used?

Feel free to explain the usage and also possibly verify my own understanding of this particular cheat sheet's usage instead. Back before you could use prepared statements, SQL queries were normally made using concatenated strings.

This meant that whatever your input was would become part of the executed sql like this:. That first ' will close the string quote to keep the syntax valid. Then, because 1 always equals 1, you create a select statement that is always true. That means that you will select the user "John" allowing you to log in as him with no knowledge of his password.

Then -- is the SQL syntax to remark anything that comes after it. This is used to eliminate any other conditions that might prevent your successful login such as IP validation or something of that nature. Many developers put too much trust in prepared statements.

Just because it does not execute input at the SQL transaction does not mean it can't contain stuff that can be executed later. This means that when your program goes to take this from your database and run it, you'll execute a JavaScript that remarks the remainder of your page, then it will kill your program when you try to load the output of that information.

In short your source is mixing up remarking syntax for 2 different kinds of attacks, but they are both legitimate concerns given the right vulnerabilities. Sign up to join this community.

This cheat sheet is of good reference to both seasoned penetration tester and also those who are just getting started in web application security. We have updated it and moved it over from our CEO's blog.

Some of the samples in this sheet might not work in every situation because real live environments may vary depending on the usage of parenthesis, different code bases and unexpected, strange and complex SQL sentences.

Bug Bounty Hunting - PHP Code Injection

Samples are provided to allow you to get basic idea of a potential attack and almost every section includes a brief information about itself. Comments out rest of the query. Line comments are generally useful for ignoring rest of the query so you don't have to deal with fixing the syntax. Executing more than one query in one transaction. This is very useful in every injection point, especially in SQL Server back ended applications.

Can someone clarify? Get response based on an if statement. This is one of the key points of Blind SQL Injectionalso can be very useful to test simple stuff blindly and accurately.

String related operations. These can be quite useful to build up injections which are not using any quotes, bypass any other black listing or determine back end database. With union you do SQL queries cross-table. Basically you can poison query to return records from another table. If application is first getting the record by username and then compare returned MD5 with supplied password's MD5 then you need to some extra tricks to fool application to bypass authentication.

You can union results with a known password and MD5 hash of supplied password. In this case application will compare your password and your supplied MD5 hash instead of MD5 from database.

You'll get convert errors before union target errors! So start with convert then union. It's a constant. You can just select it like any other column, you don't need to supply table name.


Also, you can use insert, update statements or in functions. Insert a file content to a table. Write text file. Login Credentials are required to use this function. You need to have admin access.

Beranda hack injection sql web. Hai sobat!! Bertemu lagi ama saya diblog sederhana ini.

SQL Injection Bypassing WAF

Kali ini saya akan share mengenai SQl Injection. Sebelumnya, apa itu SQl Injection?? SQl Injection memiliki makna dan arti yaitu sebuah teknik yang menyalahgunakan sebuah celah keamanan yang terjadi dalam lapisan basis data sebuah aplikasi. Celah ini terjadi ketika masukan pengguna tidak disaring secara benar dari karakter-karakter pelolos bentukan string yang diimbuhkan dalam pernyataan SQL atau masukan pengguna tidak bertipe kuat dan karenanya dijalankan tidak sesuai harapan.

Ini sebenarnya adalah sebuah contoh dari sebuah kategori celah keamanan yanglebih umum yang dapat terjadi setiap kali sebuahbahasa pemrograman atau skrip diimbuhkan di dalam bahasa yang lain. Wikipedia SQL injection adalah jenis aksi hacking pada keamanan komputer di mana seorang penyerang bisa mendapatkan akses ke basis data di dalam sistem.

SQL injection yaitu serangan yang mirip dengan serangan XSS dalam bahwa penyerang memanfaatkan aplikasi vektor dan juga dengan Common dalam serangan XSS SQL injection exploits dan sejenisnya adalah hasil interfacing sebuah bahasa lewat informasi melalui bahasa lain. Jika data yang diterima dari pengguna akhir yang dikirim langsung ke database dan tidak disaring dengan benar, maka yang penyerang dapat menyisipkan perintah SQL nya sebagai bagian dari input.

Langsung simak caranya : 1. Pergi ke www. Tulis dork nya. Misal admin. Maka, dork nya menjadi inurl: admin. Lalu pilih halaman login admin panel yang muncul. Lalu sobat akan disuguhi form login Username dan Password. Hanya beberapa yang work untuk beberapa website Jadi, 1 kode hanya untuk website tertentu.

NB : Semua tindakan yang Kamu lakukan menggunakan trik ini adalah tanggung jawab kamu sepenuhnya. Saya share trik ini hanya untuk teknik pembelajaran saja. Saya tidak bertanggung jawab!! Okelah, itu saja yang dapat saya bagikan.
