Overview
We will be discussing the vulnerability CVE-2025-4987, a serious security flaw found in the Opportunity Management module of Project Portfolio Manager. The vulnerability emerged in the software’s releases from 3DEXPERIENCE R2023x through to the R2025x version. This vulnerability is a stored Cross-Site Scripting (XSS) exploit that allows a malicious actor to execute arbitrary script code within a user’s browser session. This type of vulnerability is especially dangerous as it directly affects the security of data and the overall integrity of an organization’s system.

How the Exploit Works
The exploit works by taking advantage of a stored XSS vulnerability present in the Opportunity Management module of Project Portfolio Manager. The attacker injects malicious scripts into the system, which are then stored and executed in the user’s browser session. This can lead to unauthorized access, system compromise, and potential data leakage.
Conceptual Example Code
Here is a conceptual example of how this vulnerability might be exploited. The attacker would craft a malicious payload and send it to the server, which then gets stored and served to the user’s browser.
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "<script>/*...malicious javascript code...*/</script>" }Once the user’s browser renders the malicious script, it executes within the context of the user’s session, which can then lead to serious security breaches such as data theft or system compromise.
Mitigation Measures
The primary mitigation against this vulnerability is to apply the patch provided by the vendor. In the event that the patch cannot be applied immediately, employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation measures. These systems can detect and block XSS attacks, providing an additional layer of security against potential exploitation.
Moreover, always remember that education and awareness are powerful tools in cybersecurity. Users should be trained to recognize potential attacks and to avoid clicking on suspicious links or opening untrusted documents.
