How CVE-2025-31682 Works
This vulnerability arises due to improper input sanitization in the Drupal Google Tag module. Attackers can inject malicious JavaScript via crafted payloads in web requests, which are then executed in victims’ browsers when the tainted data is rendered. The flaw exists in versions 0.0.0 to 1.8.0 and 2.0.0 to 2.0.8, allowing stored or reflected XSS attacks. Since the module handles tracking tags, unauthenticated users may exploit this by manipulating tag parameters, leading to session hijacking or phishing.
DailyCVE Form:
Platform: Drupal
Version: <1.8.0, <2.0.8
Vulnerability: XSS
Severity: Critical
Date: 06/02/2025
Prediction: Patch by 07/15/2025
What Undercode Say:
Exploitation:
1. Craft malicious script in Google Tag parameters:
<img src=x onerror=alert(document.cookie)>
2. Use curl to test payload injection:
curl -X POST "http://target.com/admin/config/system/google_tag" -d "field=<script>alert(1)</script>"
Protection:
1. Apply module update immediately.
2. Add CSP headers in `settings.php`:
header("Content-Security-Policy: default-src 'self'");
3. Use Drupal’s built-in sanitization:
$clean_input = \Drupal\Component\Utility\Html::escape($user_input);
Analytics:
- Attack Complexity: Low (no auth required)
- Exploit Prevalence: High due to module popularity.
- Mitigation Difficulty: Medium (requires manual patching).
Detection Commands:
grep -r "google_tag" /var/www/html/modules/
drush pm-updatestatus | grep "Google Tag"
Patch Verification:
After updating, confirm mitigation with:
if (module_exists('google_tag') && version_compare(\Drupal::VERSION, '2.0.8', '>=')) {
echo "Patched";
}
