CVE-2025-10556 is a stored Cross-site Scripting (XSS) vulnerability classified under CWE-79, affecting the Specification Management component of Dassault Systèmes ENOVIA Specification Manager across multiple releases (3DEXPERIENCE R2023x to R2025x). This vulnerability arises from improper neutralization of user-supplied input during web page generation, allowing an attacker to inject malicious JavaScript code that is stored and later executed in the browsers of other users who access the compromised content. The vulnerability requires the attacker to have limited privileges (PR:L) and some user interaction (UI:R), such as tricking a user into viewing a maliciously crafted page or content. The attack vector is network-based (AV:N), meaning it can be exploited remotely without physical access. The vulnerability impacts confidentiality and integrity severely (C:H/I:H) but does not affect availability (A:N). The scope is changed (S:C), indicating that the vulnerability can affect resources beyond the initially vulnerable component, potentially impacting the entire ENOVIA environment or connected systems. Although no known exploits are currently reported in the wild, the high CVSS score of 8.7 reflects the significant risk posed by this vulnerability. ENOVIA Specification Manager is widely used in product lifecycle management (PLM) within engineering and manufacturing sectors, making this vulnerability particularly critical for organizations relying on these systems for sensitive design and specification data. The vulnerability could enable attackers to hijack user sessions, steal credentials, manipulate data, or perform actions on behalf of legitimate users, leading to data breaches and operational disruptions.

For European organizations, especially those in automotive, aerospace, industrial manufacturing, and engineering sectors that heavily rely on Dassault Systèmes ENOVIA Specification Manager, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive product specifications and intellectual property, resulting in confidentiality breaches and potential industrial espionage. The integrity of product data could be compromised, affecting design accuracy and downstream manufacturing processes. Given the collaborative nature of ENOVIA environments, a successful attack could propagate through multiple users and departments, amplifying the impact. Additionally, session hijacking or credential theft could facilitate further lateral movement within corporate networks. The absence of known exploits in the wild provides a window for proactive defense, but the high severity score demands urgent attention. European organizations must consider regulatory implications under GDPR if personal data is exposed or manipulated. The disruption of PLM workflows could also impact time-to-market and competitiveness in critical industries.

1. Implement strict input validation and sanitization on all user-supplied data within ENOVIA Specification Manager, focusing on the Specification Management module to prevent injection of malicious scripts. 2. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in users' browsers. 3. Enforce least privilege access controls to limit the ability of users to inject or modify content that could be exploited. 4. Monitor application logs and user activity for unusual behavior indicative of attempted XSS exploitation or session hijacking. 5. Educate users about phishing and social engineering tactics that could be used to trigger the vulnerability via user interaction. 6. Prepare for rapid deployment of vendor patches or updates once released, and subscribe to Dassault Systèmes security advisories for timely information. 7. Consider implementing Web Application Firewalls (WAF) with custom rules to detect and block XSS payloads targeting ENOVIA endpoints. 8. Conduct regular security assessments and penetration testing focused on web application vulnerabilities within the ENOVIA environment. 9. Isolate critical ENOVIA infrastructure within segmented network zones to reduce potential lateral movement in case of compromise.
