Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 30 May 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

Immediate mitigation should include restricting access to the Service Items Management interface to trusted users only and enforcing strict role-based access controls to minimize exposure.
Implement robust input validation and output encoding at the application layer, especially for user-supplied data rendered in web pages, to prevent injection of malicious scripts.
Employ Content Security Policy (CSP) headers to reduce the risk of script execution from untrusted sources.
Increase user awareness and training to recognize and avoid phishing attempts that could trigger the stored XSS payload.
Monitor logs and network traffic for unusual activity indicative of exploitation attempts, such as anomalous script execution or unexpected user actions.
Coordinate with Dassault Systèmes for timely patch deployment once available, and test patches in a controlled environment before production rollout.
Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block XSS attack patterns targeting the affected components.
Regularly audit and sanitize existing stored data in the Service Items Management system to remove any malicious scripts that may have been injected prior to mitigation.

Description

A stored Cross-site Scripting (XSS) vulnerability affecting Service Items Management in Service Process Engineer from Release 3DEXPERIENCE R2024x through Release 3DEXPERIENCE R2025x allows an attacker to execute arbitrary script code in user's browser session.

Impact

For European organizations, the impact of CVE-2025-4992 can be substantial. Service Process Engineer is used in industries requiring precise process management and engineering workflows, such as manufacturing, aerospace, automotive, and industrial design sectors prevalent in Europe. Exploitation of this stored XSS vulnerability could lead to unauthorized disclosure of sensitive process data, manipulation of service items, and potential compromise of user accounts through session hijacking or credential theft. This can disrupt business operations, damage intellectual property confidentiality, and erode trust in enterprise systems. Given the scope change (S:C), attackers might leverage this vulnerability to pivot and access other components or data within the 3DEXPERIENCE platform, amplifying the impact. The requirement for user interaction means phishing or social engineering could be used to trigger the exploit, increasing the risk in environments with less stringent user awareness. The high confidentiality and integrity impact ratings underscore the threat to data protection compliance under regulations such as GDPR, making this vulnerability particularly critical for European entities.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
