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.

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 2026-10-25.

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 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

Organizations should immediately review user privileges within DELMIA Service Process Engineer to minimize the number of users with permissions to input or manage service items. Implement strict input validation and output encoding on all user-supplied data fields related to service items to prevent injection of malicious scripts. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Monitor logs and user activity for unusual input patterns or script execution attempts. Educate users about the risks of interacting with untrusted links or content within the DELMIA environment to reduce successful social engineering. Coordinate with Dassault Systèmes for timely patch deployment once available and test patches in controlled environments before production rollout. Consider network segmentation to isolate critical DELMIA components from broader enterprise networks to limit lateral movement. Use web application firewalls (WAFs) with custom rules to detect and block XSS payloads targeting the affected modules. Finally, maintain up-to-date backups and incident response plans tailored to industrial software environments.

Description

CVE-2025-10555 is a high-severity stored Cross-site Scripting (XSS) vulnerability in Dassault Systèmes DELMIA Service Process Engineer, specifically in the Service Items Management component of Release 3DEXPERIENCE R2025x Golden. This vulnerability allows an attacker with limited privileges and requiring user interaction to inject malicious scripts that execute in the context of other users' browsers, potentially leading to theft of sensitive information and session hijacking. Although no known exploits are currently reported in the wild, the vulnerability's high CVSS score (8.7) indicates significant risk. European organizations using this software, especially in manufacturing and industrial sectors, could face confidentiality and integrity breaches. Mitigation involves applying vendor patches once available, implementing strict input validation and output encoding, and restricting user privileges. Countries with strong manufacturing bases and Dassault Systèmes customer presence, such as France, Germany, Italy, and the UK, are most likely to be affected. Defenders should prioritize monitoring for suspicious script injections and educate users about phishing attempts leveraging this vulnerability.

Impact

For European organizations, especially those in manufacturing, aerospace, automotive, and industrial engineering sectors that rely on Dassault Systèmes DELMIA products, this vulnerability poses a substantial risk. Exploitation could lead to unauthorized access to sensitive process data, intellectual property theft, and manipulation of manufacturing workflows, potentially causing operational disruptions and financial losses. The confidentiality breach could expose proprietary designs and process parameters, while integrity compromises could result in altered workflows or corrupted data, undermining product quality and safety. Given the interconnected nature of industrial systems, an attacker leveraging this XSS flaw might pivot to other internal systems, increasing the attack surface. The requirement for user interaction means social engineering or phishing campaigns could be used to trigger the exploit, increasing the risk to employees and contractors. The absence of known exploits currently provides a window for proactive defense, but the high CVSS score underscores the urgency. European organizations must consider the potential regulatory implications under GDPR if personal or sensitive data is compromised.

Summary

CVE-2025-10555 identifies a stored Cross-site Scripting (XSS) vulnerability classified under CWE-79 in the DELMIA Service Process Engineer product by Dassault Systèmes, specifically affecting the Service Items Management module in the 3DEXPERIENCE R2025x Golden release. Stored XSS vulnerabilities occur when malicious input is persistently stored by the application and later rendered in web pages without proper sanitization or encoding, allowing attackers to execute arbitrary JavaScript in the context of other users' browsers. This vulnerability requires an attacker to have limited privileges (PR:L) and user interaction (UI:R), such as tricking a user into viewing a crafted page or item, to trigger the malicious script execution. The CVSS vector indicates network attack vector (AV:N), low attack complexity (AC:L), partial privileges, and user interaction, with a scope change (S:C) meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality and integrity is high (C:H/I:H), but availability is unaffected (A:N). Exploitation could lead to session hijacking, credential theft, unauthorized actions on behalf of users, or spreading malware within the affected environment. Although no public exploits are currently known, the vulnerability's presence in a critical industrial software suite used for process engineering and manufacturing workflow management makes it a significant threat. The lack of available patches at the time of publication necessitates immediate attention to mitigation strategies.
