CVE-2025-47574 is a high-severity reflected Cross-Site Scripting (XSS) vulnerability affecting the mojoomla School Management software. This vulnerability stems from improper neutralization of input during web page generation, classified under CWE-79. Reflected XSS occurs when untrusted user input is included in web responses without proper sanitization or encoding, allowing an attacker to inject malicious scripts that execute in the context of a victim's browser. The vulnerability affects all versions up to 92.0.0 of the mojoomla School Management product. The CVSS 3.1 base score of 7.1 reflects its high impact, 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 can affect resources beyond the vulnerable component. The impact affects confidentiality, integrity, and availability at a low level, indicating that an attacker could potentially steal sensitive information, manipulate data, or cause denial of service through script execution. Although no known exploits are currently reported in the wild, the nature of reflected XSS makes it a common target for phishing, session hijacking, and other client-side attacks. The lack of available patches at the time of publication increases the urgency for organizations to implement mitigations. The vulnerability is particularly relevant for educational institutions using mojoomla School Management software, which typically handles sensitive student and staff data, making exploitation impactful.

For European organizations, especially educational institutions and school management bodies using mojoomla School Management, this vulnerability poses significant risks. Exploitation could lead to unauthorized disclosure of personal data of students and staff, violating GDPR and other data protection regulations. Reflected XSS can facilitate phishing attacks by injecting malicious scripts that mimic legitimate interfaces, potentially leading to credential theft or session hijacking. This undermines trust in the affected institutions and can result in reputational damage and legal consequences. Additionally, attackers could manipulate displayed content or disrupt availability of the management system, impacting daily operations. Given the widespread adoption of digital school management platforms in Europe, the vulnerability could affect a broad user base, including administrators, teachers, students, and parents. The cross-site scripting flaw also increases the attack surface for further exploitation, such as delivering malware or conducting targeted attacks against high-value users within the educational sector.

1. Immediate implementation of input validation and output encoding: Organizations should ensure that all user-supplied input is properly sanitized and encoded before being reflected in web pages. Employ context-aware encoding libraries to prevent script injection. 2. Deploy Web Application Firewalls (WAFs): Configure WAFs to detect and block common XSS attack patterns targeting the mojoomla School Management application. 3. Educate users: Train staff and students to recognize suspicious links and avoid clicking on untrusted URLs that could trigger reflected XSS attacks. 4. Monitor and log web traffic: Implement monitoring to detect unusual or malicious requests that may indicate exploitation attempts. 5. Isolate critical systems: Segment the network to limit the impact of a successful attack and protect sensitive data repositories. 6. Apply patches promptly: Although no patches were available at the time of disclosure, organizations should monitor mojoomla vendor announcements and apply updates as soon as they are released. 7. Use Content Security Policy (CSP): Implement CSP headers to restrict the execution of unauthorized scripts in browsers, mitigating the impact of XSS attacks. 8. Conduct regular security assessments: Perform penetration testing and code reviews focusing on input handling and output generation to identify and remediate similar vulnerabilities proactively.
