CVE-2025-0830
📋 TL;DR
A stored Cross-site Scripting (XSS) vulnerability in ENOVIA Change Manager's Meeting Management component allows attackers to inject malicious scripts that execute in users' browsers. This affects all 3DEXPERIENCE deployments from R2022x through R2024x. Users who access meeting management features are vulnerable to session hijacking, data theft, or unauthorized actions.
💻 Affected Systems
- ENOVIA Change Manager
- 3DEXPERIENCE Platform
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete account takeover, data exfiltration, or ransomware deployment through browser-based attacks on administrative users.
Likely Case
Session hijacking leading to unauthorized access to sensitive engineering data, intellectual property theft, or manipulation of change management processes.
If Mitigated
Limited impact with proper input validation and output encoding, potentially only affecting non-critical users with minimal privileges.
🎯 Exploit Status
Requires authenticated access to inject malicious scripts into meeting content. Attack complexity is medium due to need for user interaction and specific knowledge of the application.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Release 3DEXPERIENCE R2025x or later
Vendor Advisory: https://www.3ds.com/vulnerability/advisories
Restart Required: No
Instructions:
1. Upgrade to 3DEXPERIENCE R2025x or later. 2. Apply the latest security patches from Dassault Systèmes. 3. Validate that Meeting Management functionality properly sanitizes user input.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side input validation and output encoding for all user-supplied content in Meeting Management.
Custom application configuration required - no standard commands
Content Security Policy (CSP)
allImplement strict CSP headers to restrict script execution sources and prevent inline script execution.
Add CSP headers via web server configuration or application settings
🧯 If You Can't Patch
- Disable Meeting Management functionality if not required for business operations
- Implement web application firewall (WAF) rules to block XSS payloads and monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Test Meeting Management functionality by attempting to inject script tags or JavaScript payloads into meeting content fields.Check Version:
Check 3DEXPERIENCE version via administration console or system information panelVerify Fix Applied:
After patching, attempt the same XSS payloads and verify they are properly sanitized or blocked. Check that user input is encoded in output.📡 Detection & Monitoring
Log Indicators:
- Unusual meeting content modifications
- Multiple failed XSS attempts in web logs
- Suspicious script tags in meeting data
Network Indicators:
- Unexpected external script loads from meeting pages
- Suspicious JavaScript execution patterns
SIEM Query:
source="web_logs" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=") AND uri="*meeting*"
