CVE-2025-5726 is a cross-site scripting (XSS) vulnerability identified in version 1.0 of the SourceCodester Student Result Management System, specifically within the /script/academic/division-system component's Division System Page. The vulnerability arises from improper sanitization or validation of the 'Division' argument, which allows an attacker to inject malicious scripts. This flaw can be exploited remotely without authentication, although it requires user interaction to trigger the malicious payload. The vulnerability has been publicly disclosed, increasing the risk of exploitation, but no known exploits have been observed in the wild yet. The CVSS 4.0 base score is 4.8 (medium severity), reflecting that the attack vector is network-based with low attack complexity, no privileges required, but user interaction is necessary. The impact primarily affects confidentiality and integrity at a low level, with no direct availability impact. Since the vulnerability is in a student result management system, exploitation could lead to session hijacking, theft of user credentials, or defacement of web pages, potentially undermining trust in the system and exposing sensitive student data indirectly through social engineering or session manipulation.

For European organizations, particularly educational institutions using the SourceCodester Student Result Management System 1.0, this vulnerability poses a risk to the confidentiality and integrity of student data and administrative sessions. Successful exploitation could allow attackers to execute arbitrary scripts in the context of authenticated users, potentially leading to credential theft, unauthorized access to student records, or manipulation of displayed results. This could result in reputational damage, legal consequences under GDPR due to unauthorized data exposure, and disruption of academic processes. Although the vulnerability does not directly impact system availability, the indirect effects of compromised user accounts or data integrity could be significant. Given the public disclosure and ease of remote exploitation, European educational entities using this system should consider this a moderate threat.

To mitigate this vulnerability, organizations should first verify if they are using SourceCodester Student Result Management System version 1.0 and specifically the affected Division System Page. Since no official patch is currently available, immediate steps include implementing strict input validation and output encoding on the 'Division' parameter to neutralize malicious scripts. Web application firewalls (WAFs) can be configured to detect and block typical XSS payloads targeting this endpoint. Additionally, enforcing Content Security Policy (CSP) headers can reduce the impact of injected scripts. User education on phishing and suspicious links is also important due to the user interaction requirement. Monitoring web logs for unusual parameter values and anomalous user behavior can help detect exploitation attempts. Organizations should engage with the vendor for patch timelines and consider upgrading or replacing the system if no fix is forthcoming.
