CVE-2025-10070: Portabilis i-Educar Authentication Bypass

CVE-2025-10070 Overview

CVE-2025-10070 is a broken access control vulnerability in Portabilis i-Educar versions up to 2.10. The flaw affects the /enturmacao-em-lote/ endpoint, which handles bulk student class enrollment operations. An authenticated remote attacker with low privileges can abuse improper authorization checks to perform actions outside their permitted scope. The issue is classified under [CWE-266: Incorrect Privilege Assignment]. A public exploit has been disclosed, increasing the likelihood of opportunistic abuse against unpatched installations of this Brazilian school management platform.

Critical Impact
Authenticated attackers can bypass access controls on the bulk enrollment endpoint, leading to unauthorized modification of student class assignments and limited exposure of confidentiality, integrity, and availability of academic records.

Affected Products

Portabilis i-Educar versions up to and including 2.10
Deployments exposing the /enturmacao-em-lote/ endpoint to authenticated users
School management environments using the vulnerable bulk enrollment module

Technical Details for CVE-2025-10070

Vulnerability Analysis

The vulnerability resides in the /enturmacao-em-lote/ endpoint used by i-Educar for batch class enrollment. The endpoint fails to enforce proper authorization checks before processing requests. Any authenticated user, regardless of role, can invoke operations that should be restricted to administrative accounts.

Because the exploit requires only low privileges and no user interaction, an attacker with a standard account can manipulate enrollment records for students outside their authorized scope. The impact is bounded to low confidentiality, integrity, and availability effects on affected records, but repeated abuse can corrupt academic data integrity across a school district deployment.

Root Cause

The root cause is missing or incomplete server-side authorization enforcement on the bulk enrollment handler. The application appears to rely on client-side or interface-level restrictions rather than validating the caller's role and target object ownership on each request. This matches the [CWE-266] pattern of granting a subject permissions beyond what its role should allow.

Attack Vector

The attack is executed remotely over the network by an authenticated low-privileged user. The attacker sends crafted HTTP requests to the /enturmacao-em-lote/ endpoint referencing identifiers for classes or students they should not be able to modify. Because the server does not verify authorization on the target resource, the request is processed successfully. Full technical write-ups are available in the GitHub Vulnerability Report and VulDB entry #323018.

Detection Methods for CVE-2025-10070

Indicators of Compromise

Unexpected POST or GET requests to /enturmacao-em-lote/ from non-administrative user sessions
Bulk enrollment changes performed outside normal administrative business hours
Modifications to student-class associations by user accounts without a documented administrative role
Repeated requests to the endpoint referencing sequential or enumerated resource identifiers

Detection Strategies

Correlate application audit logs of enrollment changes with the acting user's assigned role in i-Educar
Flag any access to /enturmacao-em-lote/ originating from accounts that lack school-administrator privileges
Baseline normal request volume to the endpoint and alert on statistical deviations

Monitoring Recommendations

Enable verbose application logging for all authorization decisions in the enrollment module
Forward web server and i-Educar application logs to a centralized SIEM for retention and correlation
Track database changes to enrollment tables and reconcile them against approved administrative activity

How to Mitigate CVE-2025-10070

Immediate Actions Required

Inventory all Portabilis i-Educar deployments and confirm versions running 2.10 or earlier
Restrict network access to the /enturmacao-em-lote/ endpoint via reverse proxy or WAF rules to administrative source ranges
Audit recent enrollment changes for unauthorized modifications and revert as needed
Rotate credentials for any accounts suspected of misuse

Patch Information

At the time of publication, no vendor advisory URL is listed in the CVE record. Administrators should monitor the Portabilis i-Educar repository for updates addressing CVE-2025-10070 and apply fixes as soon as they are released. Refer to the VulDB CTI entry for ongoing tracking of remediation status.

Workarounds

Enforce network-level access controls that limit the /enturmacao-em-lote/ endpoint to trusted administrative workstations
Temporarily disable the bulk enrollment feature if operationally acceptable until a patch is available
Review and tighten role definitions to ensure only intended administrators hold accounts capable of enrollment operations

bash

# Example nginx configuration restricting the vulnerable endpoint
location /enturmacao-em-lote/ {
    allow 10.10.0.0/24;   # administrative subnet
    deny all;
    proxy_pass http://ieducar_backend;
}
