CVE-2025-11048 is a medium-severity security vulnerability identified in Portabilis i-Educar versions up to 2.10. The vulnerability arises from improper authorization controls in an unspecified functionality related to the file /consulta-dispensas. This flaw allows an attacker to remotely exploit the system without requiring user interaction or elevated privileges, as indicated by the CVSS 4.0 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 unauthorized access or manipulation of data is possible but with some constraints. The vulnerability does not require authentication, making it accessible to remote unauthenticated attackers with low attack complexity. Although no public exploit is currently known to be actively used in the wild, the exploit details have been publicly disclosed, increasing the risk of exploitation. The lack of patch links suggests that a fix may not yet be available or publicly announced, emphasizing the need for immediate mitigation efforts. The vulnerability specifically affects the i-Educar platform, an educational management system widely used in Brazil and potentially in other countries, which manages sensitive educational data and administrative functions. The improper authorization could allow attackers to access or manipulate sensitive student or institutional data, disrupt educational operations, or escalate privileges within the system.

For European organizations, particularly educational institutions or government bodies using Portabilis i-Educar or similar educational management platforms, this vulnerability poses a risk of unauthorized data access and potential disruption of educational services. The improper authorization could lead to exposure of sensitive student records, administrative data, or manipulation of educational workflows, undermining data privacy and operational integrity. Given the remote exploitability without authentication, attackers could leverage this vulnerability to conduct espionage, data theft, or sabotage, impacting the confidentiality and availability of critical educational services. The medium severity indicates that while the impact is significant, it may not lead to full system compromise or widespread disruption without additional vulnerabilities or conditions. However, the public disclosure of the exploit increases the urgency for European organizations to assess their exposure and implement mitigations promptly to prevent potential attacks.

European organizations should immediately conduct an inventory to determine if Portabilis i-Educar versions 2.0 through 2.10 are in use within their environment. In the absence of an official patch, organizations should implement strict network segmentation to isolate the i-Educar system from untrusted networks and limit access to trusted administrative users only. Employing web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting /consulta-dispensas can reduce attack surface. Monitoring and logging access to the affected endpoint should be enhanced to detect anomalous activities indicative of exploitation attempts. Organizations should also engage with Portabilis for updates on patches or mitigations and plan for rapid deployment once available. Additionally, applying the principle of least privilege for all users interacting with the system and conducting regular security assessments and penetration testing focused on authorization controls can help identify and remediate similar issues proactively.
