CVE-2025-11050 is a medium-severity vulnerability identified in the Portabilis i-Educar platform, versions 2.0 through 2.10. i-Educar is an open-source educational management system widely used in school administration to manage academic periods, student data, and other educational processes. The vulnerability resides in an unspecified component related to the /periodo-lancamento file or endpoint, which is likely involved in managing academic period releases or scheduling. The flaw is characterized as an improper authorization issue, meaning that the system fails to correctly enforce access controls, allowing unauthorized users to perform actions or access data beyond their privileges. The vulnerability can be exploited remotely without user interaction and requires low privileges (PR:L) but no authentication is needed (AT:N). The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The exploit details have been published, increasing the risk of exploitation, although no active exploitation in the wild has been reported yet. This vulnerability could allow attackers to manipulate or access sensitive educational data, potentially altering academic schedules or records, which could disrupt school operations and compromise data integrity and confidentiality.

For European organizations, particularly educational institutions using Portabilis i-Educar or similar platforms, this vulnerability poses a risk of unauthorized access and manipulation of critical academic data. The improper authorization flaw could enable attackers to alter academic periods, schedules, or related administrative data, leading to operational disruptions, loss of trust, and potential data breaches involving student and staff information. Given the sensitivity of educational data and the regulatory environment in Europe, including GDPR, unauthorized data access could result in legal and compliance repercussions. Additionally, disruption of educational services could impact students and staff, causing reputational damage to affected institutions. Since the exploit is remotely executable without user interaction, attackers could automate attacks at scale, increasing the threat level if the platform is widely deployed in European schools.

Organizations should prioritize upgrading to a patched version of Portabilis i-Educar once available. In the absence of an official patch, administrators should implement strict network segmentation to limit access to the i-Educar management interfaces, restricting them to trusted internal networks and VPNs. Employing web application firewalls (WAFs) to detect and block suspicious requests targeting the /periodo-lancamento endpoint can reduce exposure. Conduct thorough access control reviews to ensure that permissions are correctly configured and that no excessive privileges are granted to users or service accounts. Regularly monitor logs for unusual activity related to academic period management functions. Additionally, implement multi-factor authentication (MFA) for administrative access to reduce the risk of privilege escalation. Finally, maintain an incident response plan tailored to educational environments to quickly address any exploitation attempts.
