CVE-2025-11047 is a medium-severity vulnerability affecting Portabilis i-Educar versions 2.0 through 2.10. The vulnerability arises from improper authorization controls in an unspecified function within the /module/Api/aluno file. Specifically, manipulation of the aluno_id parameter allows an attacker to bypass authorization checks. This flaw can be exploited remotely without requiring user interaction or elevated privileges, as indicated by the CVSS vector (AV:N/AC:L/AT:N/PR:L/UI:N). The vulnerability impacts confidentiality, integrity, and availability to a limited extent (VC:L/VI:L/VA:L), suggesting that an attacker could access or modify student-related data improperly, potentially leading to unauthorized data disclosure or modification. The vulnerability does not require authentication but does require low privileges (PR:L), which implies that an attacker needs some level of access, possibly a low-privileged user account, to exploit the flaw. No patches or fixes are currently linked, and no known exploits are reported in the wild, although a public exploit is available, increasing the risk of exploitation. The vulnerability affects a core API module related to student data management, which is critical for educational institutions using i-Educar for administrative and academic processes.

For European organizations, particularly educational institutions using Portabilis i-Educar, this vulnerability poses a significant risk to the confidentiality and integrity of student data. Unauthorized access or manipulation of student records could lead to privacy violations under GDPR, reputational damage, and potential legal consequences. The availability impact, while limited, could disrupt administrative operations if exploited to alter or delete critical data. Given that i-Educar is an education management system, exploitation could undermine trust in digital education platforms and affect operational continuity. The medium severity suggests that while the threat is not critical, it is sufficiently serious to warrant immediate attention, especially in environments where student data protection is paramount.

Organizations should immediately audit their deployment of Portabilis i-Educar to identify affected versions (2.0 to 2.10). Until an official patch is released, implement strict access controls to limit the number of users with low-level privileges that can access the /module/Api/aluno endpoint. Employ network-level restrictions such as IP whitelisting or VPN access to reduce exposure of the API to untrusted networks. Monitor logs for unusual activity related to the aluno_id parameter to detect potential exploitation attempts. Additionally, consider implementing Web Application Firewall (WAF) rules to detect and block suspicious parameter manipulations targeting this endpoint. Engage with Portabilis support or community channels to obtain or request patches and updates. Finally, conduct user training to raise awareness about the risk of unauthorized data access and encourage reporting of anomalies.
