CVE-2025-15372 is a cross-site scripting vulnerability identified in the youlaitech vue3-element-admin product, affecting versions 3.0 through 3.4.0. The vulnerability exists due to improper handling of user-controllable input in the Notice Handler component, specifically within the source file src/views/system/notice/index.vue. This flaw allows remote attackers to inject malicious JavaScript code that executes in the context of the victim's browser when they interact with the affected notice interface. The attack vector is network-based with low attack complexity, requiring no authentication but necessitating user interaction, such as clicking a malicious link or viewing a crafted notice. The vulnerability impacts confidentiality and integrity by enabling theft of session tokens, credentials, or performing unauthorized actions on behalf of the user. The vendor was notified but has not issued a patch or response, and public exploit code is available, increasing the risk of exploitation. The CVSS 4.0 score of 4.8 reflects a medium severity, considering the ease of exploitation and potential impact. No known exploits in the wild have been reported yet, but the availability of exploit code means attackers could leverage this vulnerability soon. The lack of vendor response and patch availability means organizations must implement interim mitigations. The vulnerability is particularly relevant for organizations using vue3-element-admin as part of their web administration interfaces, especially those relying on the affected versions. Given the widespread use of Vue.js frameworks in Europe, this vulnerability could have broad implications if not addressed.

For European organizations, exploitation of CVE-2025-15372 could lead to unauthorized access to sensitive information, session hijacking, and manipulation of administrative functions within web applications using vue3-element-admin. This could result in data breaches, loss of user trust, and potential regulatory penalties under GDPR if personal data is compromised. The vulnerability could be leveraged to conduct further attacks within the network, such as lateral movement or privilege escalation, especially if the admin panel controls critical infrastructure or sensitive business functions. The medium severity score indicates moderate risk, but the availability of public exploits and lack of vendor patching increase the urgency. Organizations in sectors like finance, healthcare, and government, which often deploy web admin panels for internal management, are particularly at risk. The impact on availability is limited, but the confidentiality and integrity risks are significant enough to warrant immediate attention. Additionally, the vulnerability could be used as a foothold for more complex attacks, amplifying its potential damage.

1. Immediately implement strict input validation and sanitization on all user inputs processed by the Notice Handler component, especially in the affected src/views/system/notice/index.vue file. 2. Deploy a robust Content Security Policy (CSP) that restricts the execution of inline scripts and limits sources of executable code to trusted domains. 3. Monitor web application logs and network traffic for unusual or suspicious activity indicative of XSS exploitation attempts. 4. Educate users and administrators about the risks of clicking unknown links or interacting with untrusted notices within the admin interface. 5. If feasible, temporarily disable or restrict access to the Notice Handler functionality until an official patch is released. 6. Keep all dependencies and frameworks up to date, and subscribe to vendor or community advisories for updates on patches. 7. Consider implementing Web Application Firewalls (WAF) with rules designed to detect and block XSS payloads targeting this component. 8. Conduct regular security assessments and penetration testing focusing on web interface vulnerabilities. 9. Prepare incident response plans to quickly address any exploitation attempts. 10. Engage with the vendor or community to encourage timely patch development and disclosure.
