How CVE-2025-0692 Works
The Simple Video Management System WordPress plugin (up to v1.0.4) fails to sanitize and escape certain settings, allowing authenticated attackers (e.g., administrators) to inject malicious JavaScript payloads. This stored XSS vulnerability bypasses WordPress’ `unfiltered_html` restriction, making it exploitable in multisite configurations where this capability is disabled. Attackers can craft malicious requests to modify plugin settings, persisting arbitrary scripts that execute when other users access affected pages.
DailyCVE Form
Platform: WordPress
Version: ≤1.0.4
Vulnerability: Stored XSS
Severity: High
Date: 2025-05-25
Prediction: Patch by 2025-06-10
What Undercode Say:
Exploitation
1. Payload Injection:
POST /wp-admin/options.php HTTP/1.1 Host: target.com Content-Type: application/x-www-form-urlencoded Cookie: [bash] svms_settings[bash]="><script>alert(document.cookie)</script>
2. Trigger: Victims loading any page using the compromised plugin setting execute the payload.
Protection
1. Immediate Mitigation:
Remove plugin if unused wp plugin delete simple-video-management-system
2. WAF Rule:
location /wp-content/plugins/simple-video-management-system/ {
deny all;
}
3. Patch Check:
wp plugin update --dry-run --all
Detection
1. Scan Plugin:
grep -r "add_option|update_option" /path/to/plugin
2. Audit Logs:
SELECT FROM wp_options WHERE option_name LIKE 'svms_settings%';
3. Curl Check:
curl -s "https://target.com/wp-json/wp/v2/posts" | grep -q "svms_settings" && echo "Vulnerable"
Post-Patch Actions
1. Sanitization Audit:
// Validate plugin settings
if (!wp_verify_nonce($_POST['nonce'], 'svms_update')) { die(); }
$clean_value = sanitize_text_field($_POST['svms_setting']);
2. CSRF Protection:
add_action('admin_init', function() {
register_setting('svms_group', 'svms_settings', 'sanitize_callback');
});
3. Content Security Policy (CSP):
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline'
Analytics:
- Exploitability: High (admin-level req.)
- Attack Vector: Web-based
- Patch Complexity: Low (input sanitization fix)
