CVE-2025-40587 Details Status: Awaiting Analysis Published on: 10 Feb 2026, 10:15 UTC CVSS Release: version 3 CVSS3 Source productcert@siemens.com CVSS3 Type Primary CVSS3 Vector CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N CVE-2025-40587 Vulnerability Summary CVE-2025-40587: A vulnerability has been identified in Polarion V2404 (All versions < V2404.5), Polarion V2410 (All versions < V2410.2). The affected application allows arbitrary JavaScript code be included in document titles. This could allow an authenticated remote attacker to conduct a stored cross-site scripting attack by creating specially crafted document titles that are later viewed by other users of the application. Assessing the Risk of CVE-2025-40587 Access Complexity Graph The exploitability of CVE-2025-40587 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs). Exploitability Analysis for CVE-2025-40587 CVE-2025-40587 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks. Understanding AC and PR A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies. Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort. Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access. CVSS Score Breakdown Chart Above is the CVSS Sub-score Breakdown for CVE-2025-40587, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability. CIA Impact Analysis Below is the Impact Analysis for CVE-2025-40587, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage. Confidentiality: High Exploiting CVE-2025-40587 can result in unauthorized access to sensitive data, severely compromising data privacy. Integrity: Low Exploiting CVE-2025-40587 may cause minor changes to data without severely impacting its accuracy. Availability: None CVE-2025-40587 does not impact system availability. CVE-2025-40587 References External References https://cert-portal.siemens.com/productcert/html/ssa-035571.html CWE Common Weakness Enumeration CWE-79 CAPEC Common Attack Pattern Enumeration and Classification XSS Using MIME Type Mismatch CAPEC-209 An adversary creates a file with scripting content but where the specified MIME type of the file is such that scripting is not expected. The adversary tricks the victim into accessing a URL that responds with the script file. Some browsers will detect that the specified MIME type of the file does not match the actual type of its content and will automatically switch to using an interpreter for the real content type. If the browser does not invoke script filters before doing this, the adversary's script may run on the target unsanitized, possibly revealing the victim's cookies or executing arbitrary script in their browser. DOM-Based XSS CAPEC-588 This type of attack is a form of Cross-Site Scripting (XSS) where a malicious script is inserted into the client-side HTML being parsed by a web browser. Content served by a vulnerable web application includes script code used to manipulate the Document Object Model (DOM). This script code either does not properly validate input, or does not perform proper output encoding, thus creating an opportunity for an adversary to inject a malicious script launch a XSS attack. A key distinction between other XSS attacks and DOM-based attacks is that in other XSS attacks, the malicious script runs when the vulnerable web page is initia
