CVE-2025-10552
📋 TL;DR
A stored Cross-site Scripting (XSS) vulnerability in 3DSwym within 3DSwymer on Release 3DEXPERIENCE R2025x allows attackers to inject malicious scripts that execute in users' browsers when viewing affected content. This affects all users of the vulnerable 3DEXPERIENCE platform version who access the compromised 3DSwym component.
💻 Affected Systems
- 3DSwym
- 3DSwymer
- 3DEXPERIENCE
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or install malware on user systems through browser exploitation.
Likely Case
Session hijacking leading to unauthorized access, data theft, or manipulation of user accounts and platform content.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Stored XSS typically requires attacker to have some level of access to inject malicious payload, but execution occurs when any user views the compromised content.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched version
Vendor Advisory: https://www.3ds.com/trust-center/security/security-advisories/cve-2025-10552
Restart Required: Yes
Instructions:
1. Review vendor advisory for patch details. 2. Apply the official patch from Dassault Systèmes. 3. Restart affected services. 4. Verify the fix is applied.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd CSP headers to restrict script execution sources
Add 'Content-Security-Policy' header with appropriate directives
Input Validation Filtering
allFilter and sanitize user input in 3DSwym components
Implement input validation for all user-supplied data in 3DSwym
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads
- Disable or restrict access to 3DSwym component if not essential
🔍 How to Verify
Check if Vulnerable:
Test for XSS by attempting to inject script payloads into 3DSwym input fields and checking if they execute when viewedCheck Version:
Check 3DEXPERIENCE version through platform administration interface or system informationVerify Fix Applied:
Attempt the same XSS payload injection after patching; scripts should not execute and should be properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual script tags or JavaScript in user content submissions
- Multiple failed XSS attempts in web logs
Network Indicators:
- Unexpected external script loads in HTTP traffic
- Suspicious POST requests with script payloads
SIEM Query:
source="web_logs" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=") AND dest_port=443
