CVE-2025-47613 is a high-severity vulnerability classified under CWE-79, indicating an improper neutralization of input during web page generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the mojoomla School Management software, specifically versions up to 92.0.0. The flaw allows an attacker to inject malicious scripts into web pages viewed by other users, exploiting reflected XSS vectors. Reflected XSS occurs when user-supplied input is immediately returned by the web application without proper sanitization or encoding, enabling attackers to execute arbitrary JavaScript in the context of the victim's browser session. The CVSS 3.1 base score of 7.1 reflects a high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component, and it impacts confidentiality, integrity, and availability to a low degree each (C:L/I:L/A:L). Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the nature of XSS attacks, which can lead to session hijacking, credential theft, phishing, and unauthorized actions on behalf of legitimate users. The lack of available patches at the time of publication increases the urgency for organizations to implement interim mitigations. The vulnerability is particularly relevant for educational institutions using mojoomla School Management software, which manages sensitive student and staff data and facilitates critical administrative functions.

For European organizations, especially educational institutions and school administrations using mojoomla School Management, this vulnerability can lead to unauthorized access to sensitive personal data of students, teachers, and staff, violating data protection regulations such as GDPR. Exploitation could result in session hijacking, allowing attackers to impersonate legitimate users and perform unauthorized actions, potentially disrupting school operations or leaking confidential information. The reflected XSS could also be leveraged to deliver phishing attacks or malware to users within the institution. Given the interconnected nature of educational networks and the importance of maintaining trust and data privacy, such a vulnerability could have reputational and legal consequences. Additionally, the availability impact, although low, could still disrupt access to critical school management functions, affecting daily operations.

Since no official patches are currently available, European organizations should implement the following specific mitigations: 1) Employ Web Application Firewalls (WAFs) with rules tailored to detect and block reflected XSS payloads targeting mojoomla School Management endpoints. 2) Conduct thorough input validation and output encoding on all user-supplied data within the application, focusing on HTML, JavaScript, and URL contexts to prevent script injection. 3) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 4) Educate users and administrators about the risks of clicking on suspicious links and the importance of verifying URLs before interaction. 5) Monitor application logs and network traffic for unusual patterns indicative of attempted XSS exploitation. 6) Plan and prioritize patch deployment as soon as official fixes become available from mojoomla. 7) Consider isolating or restricting access to the affected application modules to trusted networks or VPNs to reduce exposure.
