How the Exploit Works

The vulnerability is a Stored Cross-Site Scripting (XSS) issue. An attacker can inject malicious script code into the Requirements component of the Product Manager. This code is stored and then served to users when they navigate to certain pages within the application. When the affected pages are loaded, the malicious script is executed within the user’s browser session. This can potentially lead to a full system compromise or data leakage, as the script could be designed to steal sensitive session data or perform actions on behalf of the user.

Conceptual Example Code

Here’s a conceptual example that demonstrates how an attacker might exploit this vulnerability:

POST /3dexperience/productmanager/requirements HTTP/1.1
Host: victim-organization.com
Content-Type: application/json
{ "requirement": "<script>evil_function_that_steals_data()</script>" }

In this example, the malicious script `evil_function_that_steals_data()` is inserted into the `requirement` field. When a user views this requirement, the script is executed, potentially leading to data theft or other unauthorized actions.

Recommended Mitigations

The primary recommendation for mitigating this vulnerability is to apply the vendor-supplied patch. Dassault Systèmes has released a patch that addresses this issue and it should be applied as soon as possible to all affected systems.
In situations where immediate patching is not possible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can be configured to detect and block attempts to exploit this vulnerability. However, these are only temporary measures and a patch should still be applied as soon as it is feasible.
