CVE-2025-11049 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 functionality related to the file /unificacao-aluno. This flaw allows an attacker to remotely exploit the system without requiring user interaction or elevated privileges beyond low-level privileges (PR:L). The vulnerability enables unauthorized access or manipulation of data or functions that should be restricted, potentially compromising confidentiality, integrity, and availability to a limited extent. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no user interaction (UI:N), and no privileges required (PR:L), with low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The exploit code is publicly available, increasing the risk of exploitation, although no known exploits in the wild have been reported yet. The vulnerability does not require special conditions such as user interaction or high privileges, making it easier to exploit remotely. However, the impact is somewhat limited due to the low-level privileges required and the low impact on core security properties. The lack of detailed information about the exact functionality affected limits the ability to fully assess the scope, but the vulnerability affects a critical education management platform used for student data unification, which could lead to unauthorized data access or modification if exploited.

For European organizations, particularly educational institutions using Portabilis i-Educar, this vulnerability poses a risk of unauthorized access or manipulation of student data and related educational records. Such unauthorized access could lead to data breaches involving sensitive personal information, potentially violating GDPR and other data protection regulations. Integrity issues could result in incorrect or manipulated educational records, impacting administrative decisions and student outcomes. Availability impact is likely limited but could disrupt certain functionalities related to student data unification. The public availability of exploit code increases the urgency for mitigation, as attackers could leverage this vulnerability to target educational institutions remotely. Given the sensitive nature of educational data and regulatory requirements in Europe, exploitation could lead to reputational damage, legal penalties, and operational disruptions.

Organizations should prioritize updating Portabilis i-Educar to a patched version once available from the vendor, as no patch links are currently provided. In the interim, implement strict network segmentation and access controls to limit exposure of the /unificacao-aluno endpoint to trusted internal networks only. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting this functionality. Conduct thorough access reviews to ensure that users have only the minimum necessary privileges, reducing the risk posed by low-privilege exploitation. Monitor logs for unusual access patterns or attempts to exploit this endpoint. Additionally, implement multi-factor authentication (MFA) for all users to reduce the risk of credential compromise. Engage with the vendor for timely updates and verify the integrity of the i-Educar deployment. Finally, educate IT and security teams about this vulnerability and the importance of rapid response to reduce exploitation risk.
