Unmasking the Web’s Backend: A Deep Dive into inurl:index.php?id= and the “upd” Anomaly

The Role of the Space in "inurl:index.phpid= upd"

Notice the space before upd. In Google dorking, a space acts as an AND operator. The query inurl:index.php?id= upd finds pages where the URL contains index.php?id= AND also contains upd somewhere (not necessarily immediately after). This broadens the search to include variations like:

• index.php?id=23&action=upd
• index.php?id=upd_status
• index.php?id=100&upd=true

1. SQL Injection (SQLi)

If a developer writes code like this:

$id = $_GET['id'];
$query = "SELECT * FROM products WHERE id = $id";

An attacker can modify the URL from:
index.php?id=5 to index.php?id=5 UNION SELECT username, password FROM admins inurl indexphpid upd

The upd component might trigger a different code path—perhaps an UPDATE SQL statement instead of a SELECT. If an attacker finds index.php?id=upd, they might test: index.php?id=upd' OR '1'='1 — which could modify database records without authorization.
