How the CVE Works:
CVE-2025-0531 is a critical SQL injection vulnerability found in Code-Projects Chat System 1.0. The issue resides in the `/user/leaveroom.php` file, specifically in the manipulation of the `id` parameter. Attackers can exploit this vulnerability by injecting malicious SQL queries through the `id` parameter, allowing unauthorized database access, data manipulation, or extraction. The attack can be executed remotely, making it highly dangerous. Publicly disclosed exploits are available, increasing the risk of widespread exploitation. The CVSS 4.0 score of 5.3 (MEDIUM) reflects the potential impact, with the attack vector being network-based, requiring low attack complexity, and affecting confidentiality, integrity, and availability.
DailyCVE Form:
Platform: Code-Projects Chat System
Version: 1.0
Vulnerability: SQL Injection
Severity: Critical
Date: 01/17/2025
What Undercode Say:
Exploitation:
1. Exploit Code Example:
/user/leaveroom.php?id=1' AND 1=CONVERT(int, (SELECT @@version))--
This payload attempts to extract the database version by exploiting the SQL injection vulnerability.
2. Automated Exploitation:
Use tools like `sqlmap` to automate the exploitation process:
sqlmap -u "http://target.com/user/leaveroom.php?id=1" --dbs
3. Exploit URL:
http://target.com/user/leaveroom.php?id=1' UNION SELECT null,user(),null--
Protection:
1. Input Validation:
Sanitize and validate all user inputs to prevent malicious SQL queries.
2. Parameterized Queries:
Use prepared statements to separate SQL code from user input:
$stmt = $conn->prepare("DELETE FROM rooms WHERE id = ?");
$stmt->bind_param("i", $id);
$stmt->execute();
3. Web Application Firewall (WAF):
Deploy a WAF to filter out malicious SQL injection attempts.
4. Patch Management:
Regularly update the software to the latest version to mitigate known vulnerabilities.
5. Database Permissions:
Restrict database user permissions to minimize the impact of a successful attack.
6. Logging and Monitoring:
Implement logging to detect and respond to suspicious activities:
error_log("SQL Injection attempt detected: " . $_SERVER['REQUEST_URI']);
7. Security Headers:
Add security headers to mitigate other potential attack vectors:
Header set X-Content-Type-Options "nosniff" Header set X-Frame-Options "DENY"
8. Testing:
Conduct regular penetration testing to identify and fix vulnerabilities.
9. References:
10. Additional Tools:
- Use `Burp Suite` for manual testing.
- Deploy `ModSecurity` as a WAF solution.
By following these steps, you can mitigate the risks associated with CVE-2025-0531 and protect your systems from SQL injection attacks.
