SQLi simulation using a virtual machine

Demonstration/simulation of SQL Injection attacks (In-band, Union-based, Blind SQLi) using a Kali Linux virtual machine and a Damn Vulnerable Web Application (DVWA) on a low difficulty level

Blind SQL provided in the video can be used also for gaining other sensitive information: length of the name of the database, database name itself etc.

the common attacks are shown and described shortly in the video, but of course for better learning you can try it yourself.

more resources where you can try out exploiting SQLi vulnerability:

- Try Hack Me SQLi Lab

- W3Schools SQL Injection

- Hacksplaining SQL Injection

more advanced pokemons can try:

- Try Hack Me SQli Advanced Lab

and of course DVWA is a great tool!

🔒 Bahaya SQL Injection: Kenapa Website Kamu Butuh Perlindungan!

Hai teman-teman! Pernah nggak sih kepikiran kalau data di website bisa bocor cuma karena satu celah kecil? Nah, itu bisa banget terjadi kalau website kita rentan terhadap SQL Injection. Aku baru aja nyobain eksperimen simpel dan juga sebagai bagian dari tugas aku gimana bahayanya, dan aku mau sharing biar kalian juga paham dan tahu cara melindungi situs kalian. Yuk, simak!

Apa Itu SQL Injection?

Jadi begini, SQL Injection itu kayak hacker nyisipin kode jahat ke website lewat inputan yang seharusnya aman. Kalau kita nggak hati-hati, kode itu bisa bikin mereka mengakses semua data di database, bahkan mengubah atau menghapusnya! Bayangin, data pribadi, password, sampai data penting lain bisa diambil cuma karena website kita nggak aman.

Eksperimen Sederhana: Melihat Kerentanan Website

Aku buat website kecil pakai PHP dan MySQL buat coba-coba. Contohnya kayak gini:

Kalau akses URL-nya kayak gini:

maka akan tampil data pengguna ID = 1

Tapi kalau diubah jadi: http://localhost/uas/index.php?id=1' OR '1'='1

tiba-tiba semua data pengguna muncul! Ini bahaya banget, kan? Website itu rentan banget kalau nggak diproteksi.

Kenapa Bahaya?

Serangan kayak gini bisa bikin data bocor, diubah, atau dihapus sama pihak nggak bertanggung jawab. Kalau data penting kayak password, data pelanggan, atau info rahasia lain bocor, reputasi dan kepercayaan bisa rusak parah.

Solusi Ampuh: Pakai Prepared Statements

Gampang banget, tinggal pakai prepared statements. Contohnya kayak ini:

Nah, dengan cara ini, input dari pengguna dianggap sebagai data, bukan bagian dari query SQL. Jadi, serangan kayak tadi nggak bakal berhasil lagi!

Tips Tambahan buat Website Aman nihh

Validasi input: Pastikan data yang masuk sesuai format yang diharapkan.

Update software & plugin: Biarkan selalu terbaru buat nutup celah.

Batasi hak akses database: Jangan kasih hak penuh ke user database.

Backup rutin: Kalau terjadi sesuatu, data bisa dipulihkan.

Kesimpulan

Gak mau kan data kita gampang diambil orang? Pelajaran pentingnya, jangan remehkan soal keamanan. Dengan langkah simpel kayak pakai prepared statements, kita bisa jauh lebih aman dari serangan SQL Injection. Yuk, mulai perhatikan keamanan website dari sekarang! Karena data kita berharga banget, guys.

Kalau kalian suka dan mau belajar lebih jauh soal keamanan web, comment atau repost ya! Aku bakal bahas lagi soal tips dan trik lainnya. kalo ingin lebih liat lengkap caranya gimana bisa langsung ke Github-ku yaa. Cheers! ✨

Remediation of SQLi

Defense Option 1: Prepared Statements (with Parameterized Queries)

Prepared statements ensure that an attacker is not able to change the intent of a query, even if SQL commands are inserted by an attacker. In the safe example below, if an attacker were to enter the userID of tom' or '1'='1, the parameterized query would not be vulnerable and would instead look for a username which literally matched the entire string tom' or '1'='1.

Defense Option 2: Stored Procedures

The difference between prepared statements and stored procedures is that the SQL code for a stored procedure is defined and stored in the database itself, and then called from the application.

Both of these techniques have the same effectiveness in preventing SQL injection so it is reasonable to choose which approach makes the most sense for you. Stored procedures are not always safe from SQL injection. However, certain standard stored procedure programming constructs have the same effect as the use of parameterized queries when implemented safely (the stored procedure does not include any unsafe dynamic SQL generation) which is the norm for most stored procedure languages.

Defense Option 3: Allow-List Input Validation

Various parts of SQL queries aren't legal locations for the use of bind variables, such as the names of tables or columns, and the sort order indicator (ASC or DESC). In such situations, input validation or query redesign is the most appropriate defense. For the names of tables or columns, ideally those values come from the code, and not from user parameters.

But if user parameter values are used to make different for table names and column names, then the parameter values should be mapped to the legal/expected table or column names to make sure unvalidated user input doesn't end up in the query. Please note, this is a symptom of poor design and a full rewrite should be considered if time allows.

Defense Option 4: Escaping All User-Supplied Input

This technique should only be used as a last resort, when none of the above are feasible. Input validation is probably a better choice as this methodology is frail compared to other defenses and we cannot guarantee it will prevent all SQL Injection in all situations.

This technique is to escape user input before putting it in a query and usually only recommended to retrofit legacy code when implementing input validation isn't cost effective.
