How CVE-2025-1669 Works
The WPSchoolPress plugin (≤ v2.2.16) for WordPress fails to sanitize user input in the `addNotify` action, allowing authenticated attackers (teacher-level+) to inject malicious SQL queries. The lack of prepared statements lets attackers append arbitrary SQL commands, enabling database exfiltration (e.g., user credentials, sensitive school records). The vulnerability stems from direct concatenation of unsanitized input into SQL queries.
DailyCVE Form:
Platform: WordPress
Version: ≤ 2.2.16
Vulnerability: SQL Injection
Severity: Critical
Date: 03/15/2025
What Undercode Say:
Exploit:
- Identify Target: Confirm WPSchoolPress ≤ v2.2.16 is active.
2. Authenticate: Gain teacher/higher credentials (phishing/password reuse).
3. Craft Payload:
POST /wp-admin/admin-ajax.php HTTP/1.1 Action=addNotify&data=1' UNION SELECT user_login,user_pass FROM wp_users-- -
4. Exfiltrate: Extract hashed passwords/session tokens.
Protection:
1. Patch: Upgrade to WPSchoolPress > v2.2.16.
- WAF Rules: Block SQLi patterns (e.g.,
UNION SELECT).location ~ union.select { deny all; }
3. Hardening:
// Replace raw queries with prepared statements:
$wpdb->prepare("INSERT INTO notifications (data) VALUES (%s)", sanitize_text_field($_POST[bash]));
4. Logging: Monitor suspicious admin-ajax.php requests:
grep "addNotify" /var/log/nginx/access.log | grep -E "UNION|SELECT|--"
Detection (SQLi):
-- Check for malicious entries: SELECT FROM wp_notifications WHERE data LIKE '%UNION%';
Mitigation Commands:
1. Immediate Rollback:
wp plugin deactivate wpschoolpress --allow-root
2. DB Audit:
mysqldump -u root -p wp_db > backup_$(date +%F).sql
