Even if a user types 1 OR 1=1 , the database treats it strictly as text or a literal value, not as executable SQL code. The query will simply look for a product with the ID "1 OR 1=1" (which likely doesn't exist) and safely fail.
Google sometimes ignores URL parameters to avoid duplicate content. So some shops might have dynamic product pages that are not indexed at all. You can still use the site: operator, but results may be incomplete.
$id = $_GET['id']; $query = "SELECT * FROM products WHERE id = $id"; $result = mysqli_query($conn, $query); Use code with caution. Correct (Secure): inurl index php id 1 shop better
Because 1=1 is always true, this query could return all rows in the database, potentially leaking hidden products, user data, or administrative credentials.
Google Dorks (or Google Hacking) use advanced search operators to find information not easily available through a normal search. Even if a user types 1 OR 1=1
In a retail context, these URL structures often link directly to product pages in older or poorly secured online shops. The Story of "The Shop with a Backdoor" Imagine a small online boutique called "Shop Better"
When a user clicks a link like ://shop.com , the web server executes a database query behind the scenes that looks similar to this: SELECT * FROM products WHERE product_id = 1; Use code with caution. So some shops might have dynamic product pages
To move "better" away from this vulnerable pattern, developers should adopt more secure and modern web standards: URL Rewriting : Instead of index.php?id=1 , use human-readable and SEO-friendly "slugs" like /shop/leather-boots/ . This is often handled via or server-side routing. Prepared Statements : When using parameters like an ID, always use with prepared statements to prevent SQL injection. Input Validation : Ensure the
While a layperson might use this search hoping to find a superior online store, a security researcher sees something very different. This specific combination is famously associated with identifying vulnerabilities.
If you are a or penetration tester , I recommend:
When an e-commerce site is poorly coded, database queries look directly at the URL parameter to fetch product data. If an attacker changes id=1 to a malicious script, they can bypass security controls. Potential Impacts of SQL Injection on E-Commerce Sites:
