CVE-2024-7938
📋 TL;DR
A stored Cross-site Scripting (XSS) vulnerability in 3DDashboard within 3DSwymer allows attackers to inject malicious scripts that execute in users' browsers when viewing affected dashboard content. This affects all users of 3DEXPERIENCE R2023x through R2024x releases. Attackers could steal session cookies, redirect users, or perform actions on their behalf.
💻 Affected Systems
- 3DDashboard
- 3DSwymer
- 3DEXPERIENCE Platform
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete account takeover, data theft, privilege escalation, and lateral movement within the 3DEXPERIENCE platform
Likely Case
Session hijacking, credential theft, unauthorized actions performed in user context, and data exfiltration
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers
🎯 Exploit Status
Stored XSS typically requires authentication to inject payload, but execution affects all users viewing the compromised dashboard
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific fixed releases
Vendor Advisory: https://www.3ds.com/vulnerability/advisories
Restart Required: Yes
Instructions:
1. Review vendor advisory for specific patch details. 2. Apply the latest security update from Dassault Systèmes. 3. Restart affected 3DEXPERIENCE services. 4. Verify the fix by testing dashboard functionality.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement strict input validation for dashboard content to reject malicious scripts
Content Security Policy
allImplement CSP headers to restrict script execution sources
🧯 If You Can't Patch
- Restrict dashboard creation/modification permissions to trusted users only
- Implement web application firewall (WAF) rules to detect and block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Test dashboard functionality by attempting to inject script tags in dashboard content fieldsCheck Version:
Check 3DEXPERIENCE version through platform administration interface or vendor documentationVerify Fix Applied:
After patching, attempt the same XSS injection tests and verify scripts are properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual dashboard modifications
- Script tags in dashboard content logs
- Multiple failed XSS attempts
Network Indicators:
- Unexpected script loads from dashboard content
- Suspicious outbound connections triggered by dashboard views
