CVE-2025-14347 identifies a reflected Cross-site Scripting (XSS) vulnerability in Proliz Software Ltd.'s OBS (Student Affairs Information System)0, versions prior to 26.5009. The root cause is improper neutralization of input during web page generation, classified under CWE-79. This vulnerability allows an attacker to craft malicious URLs or input that, when processed by the vulnerable system, reflect the injected script back to the user's browser without proper sanitization. The reflected XSS can execute arbitrary JavaScript in the context of the victim's session, potentially leading to theft of authentication tokens, session hijacking, or unauthorized actions performed on behalf of the user. The CVSS v3.1 score is 6.3 (medium), reflecting network attack vector (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), and user interaction (UI:R). The impact on confidentiality is high (C:H) due to possible data exposure, integrity impact is low (I:L), and availability is not affected (A:N). No public exploits are currently known, but the vulnerability is publicly disclosed and should be addressed promptly. The affected product is primarily used in educational institutions for student affairs management, making the confidentiality of student data a critical concern. The lack of available patches at the time of disclosure necessitates immediate mitigation through input validation and output encoding best practices.

For European organizations, particularly educational institutions using the OBS (Student Affairs Information System)0, this vulnerability poses a significant risk to the confidentiality of sensitive student and staff data. Exploitation could lead to unauthorized access to personal information, session hijacking, and potential unauthorized actions within the system. This could result in data breaches, reputational damage, and regulatory non-compliance under GDPR. Although the vulnerability does not affect system availability or integrity substantially, the exposure of confidential data is critical. The requirement for user interaction limits automated exploitation but targeted phishing or social engineering attacks could facilitate exploitation. The medium severity rating suggests that while the threat is serious, it is not critical, but timely remediation is essential to prevent escalation or chaining with other vulnerabilities.

1. Apply official patches or updates from Proliz Software Ltd. as soon as they become available to address the vulnerability directly. 2. Implement strict input validation on all user-supplied data, ensuring that potentially malicious characters are sanitized or rejected before processing. 3. Employ context-aware output encoding (e.g., HTML entity encoding) when reflecting user input in web pages to prevent script execution. 4. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 5. Educate users and administrators about the risks of clicking on suspicious links and encourage cautious handling of URLs received via email or other communication channels. 6. Conduct regular security assessments and penetration testing focused on web application vulnerabilities to detect similar issues proactively. 7. Monitor web application logs for unusual input patterns or error messages that may indicate attempted exploitation. 8. Consider implementing Web Application Firewalls (WAF) with rules designed to detect and block reflected XSS payloads targeting the OBS system.
