CVE-2025-4988
📋 TL;DR
A stored Cross-site Scripting (XSS) vulnerability in Dassault Systèmes' 3DEXPERIENCE platform allows attackers to inject malicious scripts into Results Analytics in Multidisciplinary Optimization Engineer. When users view affected content, the scripts execute in their browser sessions, potentially compromising their accounts. This affects organizations using 3DEXPERIENCE R2022x through R2024x.

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, perform session hijacking, install malware on user systems, or pivot to internal network resources through compromised accounts.
Likely Case
Attackers steal user session cookies and authentication tokens to impersonate legitimate users, potentially accessing sensitive engineering data or modifying optimization results.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before reaching users, preventing execution while maintaining functionality.
🎯 Exploit Status
Stored XSS typically requires some level of access to inject malicious content, but once injected, exploitation is straightforward for any user viewing the content.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://www.3ds.com/vulnerability/advisories
Restart Required: Yes
Instructions:
1. Review Dassault Systèmes security advisory. 2. Apply the latest security update for your 3DEXPERIENCE version. 3. Restart affected services. 4. Verify the fix by testing XSS payloads in Results Analytics.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement additional input validation on Results Analytics data entry points to reject or sanitize script tags and JavaScript content.
Configuration through 3DEXPERIENCE administration console
Content Security Policy
allImplement strict Content Security Policy 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
- Implement web application firewall (WAF) rules to block XSS payloads targeting Results Analytics endpoints
- Restrict user permissions to minimize who can create or modify content in Results Analytics
🔍 How to Verify
Check if Vulnerable:
Test by attempting to inject basic XSS payloads (e.g., <script>alert('XSS')</script>) into Results Analytics fields and checking if they execute when viewed.Check Version:
Check 3DEXPERIENCE version through administration console or system information panelsVerify Fix Applied:
After patching, repeat XSS testing with common payloads; scripts should be properly encoded or rejected without execution.📡 Detection & Monitoring
Log Indicators:
- Unusual content submissions to Results Analytics containing script tags or JavaScript patterns
- Multiple failed login attempts following content views
Network Indicators:
- Outbound connections to suspicious domains following Results Analytics access
- Unusual data exfiltration patterns
SIEM Query:
