Overview
The cybersecurity landscape is constantly changing and evolving, with new vulnerabilities being discovered and exploited by malicious actors. One such vulnerability that has recently been identified is the CVE-2025-4986 which affects Model Definition in the Product Manager from Release 3DEXPERIENCE R2022x through Release 3DEXPERIENCE R2025x.
This vulnerability is of particular concern due to its potential to allow an attacker to execute arbitrary script code in a user’s browser session, which could potentially lead to system compromise or data leakage. In this blog post, we will take a deep dive into the characteristics of this vulnerability, how it works, and how to mitigate its impacts.

How the Exploit Works
CVE-2025-4986 is a Stored Cross-Site Scripting (XSS) vulnerability. An attacker can exploit this vulnerability by injecting malicious scripts into a web page viewed by other users. When these scripts are stored on the target server and served as part of a web page, the browser executing them does not recognize these scripts as being dangerous, and executes them as if they were part of the web page’s legitimate code.
This allows the attacker to hijack user sessions, deface web sites, or redirect the user to malicious sites. In this case, the vulnerability is present in the Model Definition component of the 3DEXPERIENCE Product Manager, allowing an attacker to potentially compromise the system or leak data.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited:
POST /3dexperience/model HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"model_definition": "<script>malicious_code_here</script>"
}In this example, the attacker sends a POST request to a vulnerable endpoint, embedding a malicious script in the model_definition parameter. When this malicious code is stored and then served to a user, their browser would execute the malicious code.
Mitigation Guidance
To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it is available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may provide temporary mitigation. Regularly updating and patching your systems can help prevent exploitation of such vulnerabilities, as well as implementing a robust cybersecurity strategy. Regular security audits and penetration testing can also help identify and mitigate such vulnerabilities before they can be exploited.
