CVE-2025-64232 is a reflected Cross-site Scripting (XSS) vulnerability identified in the 'Import from YML' module of the icopydoc software, affecting versions up to and including 3.1.17. The root cause is improper neutralization of user-supplied input during web page generation, which allows attackers to inject malicious JavaScript code that is reflected back to users without proper sanitization. This vulnerability can be exploited remotely over the network without requiring authentication, but it does require user interaction, such as clicking a maliciously crafted URL. The CVSS 3.1 base score of 7.1 reflects its high severity, with attack vector being network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but user interaction required (UI:R). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The impact includes limited confidentiality, integrity, and availability losses (C:L/I:L/A:L), such as session hijacking, defacement, or redirecting users to malicious sites. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk to organizations using this component, especially those that rely on importing YML data for content management or document processing. The vulnerability was reserved on 2025-10-29 and published on 2025-11-06, with no patches currently linked, indicating that remediation may still be pending or in progress. The lack of CWE classification suggests a need for further analysis, but the nature of the vulnerability clearly aligns with CWE-79 (Improper Neutralization of Input During Web Page Generation).

For European organizations, this vulnerability can lead to unauthorized disclosure of sensitive information, session hijacking, and potential defacement or redirection attacks that undermine user trust and brand reputation. Sectors such as publishing, content management, and any enterprise relying on icopydoc's Import from YML feature are particularly at risk. The reflected XSS can be leveraged in phishing campaigns targeting employees or customers, increasing the risk of credential theft or malware delivery. The vulnerability's network accessibility and lack of required privileges make it a viable attack vector for external threat actors. Additionally, the changed scope means that exploitation could impact other components or systems beyond the immediate vulnerable module, potentially leading to broader compromise. The absence of known exploits in the wild provides a window for proactive mitigation, but the high CVSS score underscores the urgency. Failure to address this vulnerability could result in regulatory penalties under GDPR if personal data is compromised, as well as operational disruptions.

1. Monitor icopydoc vendor communications closely for official patches addressing CVE-2025-64232 and apply them promptly once available. 2. Implement strict input validation and output encoding on all user-supplied data, especially in the Import from YML functionality, to prevent injection of malicious scripts. 3. Deploy a robust Content Security Policy (CSP) to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 4. Conduct security code reviews and penetration testing focused on web input handling to identify and remediate similar vulnerabilities proactively. 5. Educate users and administrators about the risks of clicking on suspicious links and the importance of verifying URLs, to reduce the effectiveness of phishing attempts leveraging this vulnerability. 6. Use web application firewalls (WAFs) with updated signatures to detect and block reflected XSS attack patterns targeting this component. 7. Isolate critical systems and limit exposure of the Import from YML interface to trusted networks where possible. 8. Maintain comprehensive logging and monitoring to detect anomalous activities indicative of exploitation attempts.
