CVE-2024-7737
📋 TL;DR
A stored Cross-site Scripting (XSS) vulnerability in 3DSwym component of 3DSwymer allows attackers to inject malicious scripts that execute in users' browsers when viewing affected content. This affects all 3DEXPERIENCE users from R2022x through R2024x releases. Attackers could steal session cookies, redirect users, or perform actions on their behalf.
💻 Affected Systems
- 3DSwym
- 3DSwymer
- 3DEXPERIENCE Platform
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- 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
Complete account takeover, data theft, privilege escalation, and lateral movement within the 3DEXPERIENCE platform leading to intellectual property theft or system compromise.
Likely Case
Session hijacking, credential theft, unauthorized actions performed in victim's context, and data exfiltration from the affected user's session.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers preventing script execution.
🎯 Exploit Status
Stored XSS typically requires some level of access to inject payloads, but exploitation is straightforward once payload is stored.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Dassault Systèmes advisory for specific fixed versions
Vendor Advisory: https://www.3ds.com/vulnerability/advisories
Restart Required: Yes
Instructions:
1. Review Dassault Systèmes security advisory. 2. Apply the latest security patch for your 3DEXPERIENCE version. 3. Restart affected services. 4. Verify the fix by testing XSS payloads.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd strict CSP headers to prevent inline script execution and restrict script sources
Add 'Content-Security-Policy: script-src 'self'' to web server configuration
Input Validation Filtering
allImplement server-side input validation to sanitize user inputs in 3DSwym components
Implement HTML encoding for user-generated content before storage and display
🧯 If You Can't Patch
- Disable or restrict access to 3DSwym components until patching is possible
- Implement web application firewall (WAF) rules to block XSS payload patterns
🔍 How to Verify
Check if Vulnerable:
Test by attempting to inject basic XSS payloads (e.g., <script>alert('XSS')</script>) into 3DSwym content fields and check if they execute when viewedCheck Version:
Check 3DEXPERIENCE version through administration console or contact Dassault Systèmes supportVerify Fix Applied:
After patching, attempt the same XSS payload injection and verify scripts do not execute📡 Detection & Monitoring
Log Indicators:
- Unusual content submissions to 3DSwym with script tags or JavaScript code
- Multiple failed login attempts from new locations following content views
Network Indicators:
- Outbound connections to suspicious domains following 3DSwym content access
- Unexpected POST requests with encoded script payloads
