CVE-2025-8510 is a cross-site scripting (XSS) vulnerability identified in version 2.10 of Portabilis i-Educar, an educational management system. The vulnerability exists in the 'Gerar' function within the file ieducar/intranet/educar_matricula_lst.php. Specifically, it arises from improper sanitization or validation of the 'ref_cod_aluno' parameter, which can be manipulated by an attacker to inject malicious scripts. This flaw allows remote attackers to execute arbitrary JavaScript code in the context of the victim's browser without requiring authentication. The vulnerability is classified as problematic with a CVSS 4.0 base score of 5.1 (medium severity), reflecting its moderate impact and ease of exploitation. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:L), but user interaction is necessary (UI:P). The vulnerability affects confidentiality and integrity to a limited extent but does not impact availability or system control. A patch identified by commit 82c288b9a4abb084bdfa1c0c4ef777ed45f98b46 has been released to address this issue. The vendor initially closed the advisory without requesting a CVE, but the vulnerability has since been publicly disclosed. No known exploits are currently active in the wild, but the public disclosure increases the risk of exploitation.

For European organizations, especially educational institutions and government bodies using Portabilis i-Educar 2.10, this vulnerability poses a risk of session hijacking, credential theft, or unauthorized actions performed on behalf of legitimate users. Since i-Educar is an education management platform, exploitation could lead to exposure of sensitive student data or manipulation of enrollment records. The XSS vulnerability could also be leveraged to deliver further malware or phishing attacks targeting staff and students. Although the vulnerability requires user interaction, the widespread use of web browsers in educational environments increases the likelihood of successful exploitation. The impact on confidentiality and integrity could undermine trust in educational services and lead to regulatory compliance issues under GDPR if personal data is compromised.

Organizations should prioritize applying the official patch identified by commit 82c288b9a4abb084bdfa1c0c4ef777ed45f98b46 to remediate the vulnerability. In addition, administrators should implement strict input validation and output encoding for all user-supplied data, particularly parameters like 'ref_cod_aluno'. Employing Content Security Policy (CSP) headers can help mitigate the impact of XSS by restricting the execution of unauthorized scripts. Regularly updating the i-Educar platform and monitoring web application logs for suspicious activity related to the vulnerable endpoint is recommended. User awareness training to recognize phishing and suspicious links can reduce the risk of exploitation via social engineering. Network-level protections, such as web application firewalls (WAFs), can be configured to detect and block common XSS attack patterns targeting this parameter.
