CVE-2025-5011 is a cross-site scripting (XSS) vulnerability identified in version 4.3.0 of the moonlightL hexo-boot product, specifically within the /admin/home/index.html file of the Dynamic List Page component. The vulnerability arises from improper input validation or sanitization, allowing an attacker to inject malicious scripts into the web interface. This flaw can be exploited remotely without authentication, although user interaction is required to trigger the malicious script (e.g., an administrator visiting a crafted URL or page). The CVSS 4.0 base score is 4.8, indicating a medium severity level. The vector details show that the attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:H indicates high privileges required, but the description states remote initiation, so this may be a discrepancy), and user interaction is necessary (UI:P). The vulnerability impacts the confidentiality and integrity of the affected system to a limited extent, as the injected scripts could steal session tokens, manipulate the admin interface, or perform unauthorized actions within the scope of the admin user. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability disclosure is recent (published May 21, 2025), and the affected version is specifically 4.3.0 of hexo-boot, which is a product by moonlightL. The lack of detailed CWE classification and patch information suggests that mitigation may require vendor updates or manual input sanitization by administrators.

For European organizations using moonlightL hexo-boot 4.3.0, this XSS vulnerability poses a risk primarily to administrative users who access the Dynamic List Page. Successful exploitation could lead to session hijacking, unauthorized administrative actions, or the injection of malicious content into the admin interface, potentially compromising the integrity and confidentiality of sensitive data managed through the platform. Given that the vulnerability requires user interaction, phishing or social engineering attacks could be used to lure administrators into triggering the exploit. The impact is particularly significant for organizations with critical administrative operations relying on hexo-boot, such as those in sectors like finance, healthcare, or government, where data integrity and confidentiality are paramount. Additionally, if the product is integrated into larger systems or portals, the XSS could serve as a pivot point for further attacks. However, the medium severity and absence of known active exploits reduce the immediate risk, though the public disclosure increases the likelihood of future exploitation attempts.

European organizations should prioritize the following mitigation steps: 1) Immediately audit and restrict administrative access to the hexo-boot Dynamic List Page, ensuring only trusted personnel have access. 2) Implement web application firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting the affected URL paths. 3) Educate administrators about phishing and social engineering risks to reduce the chance of user interaction exploitation. 4) Monitor logs for unusual activity or access patterns to the /admin/home/index.html page. 5) Engage with the vendor moonlightL to obtain patches or updates addressing CVE-2025-5011; if unavailable, consider applying manual input validation or sanitization on the affected component. 6) Where possible, isolate the hexo-boot admin interface behind VPNs or internal networks to reduce exposure. 7) Regularly update and patch all related software components to minimize attack surface. These steps go beyond generic advice by focusing on access control, detection, user awareness, and vendor engagement specific to this vulnerability and product.
