CVE-2025-9607: Portabilis i-Educar SQL Injection Flaw

CVE-2025-9607 Overview

CVE-2025-9607 is a SQL injection vulnerability in Portabilis i-Educar versions up to 2.10. The flaw resides in the /module/TabelaArredondamento/view endpoint, part of the Tabelas de Arredondamento (Rounding Tables) page. Attackers can manipulate the id parameter to inject SQL statements into backend queries. The vulnerability is remotely exploitable and requires only low-level authentication. A public proof-of-concept demonstrating a blind time-based SQL injection technique has been published on GitHub. Portabilis i-Educar is an open-source academic management system widely deployed by Brazilian public schools and municipalities, expanding the potential exposure footprint.

Critical Impact
Authenticated remote attackers can execute arbitrary SQL queries against the i-Educar database by manipulating the id parameter, leading to data disclosure and integrity compromise.

Affected Products

Portabilis i-Educar versions up to and including 2.10
TabelaArredondamento module (Tabelas de Arredondamento page)

Technical Details for CVE-2025-9607

Vulnerability Analysis

The vulnerability is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The TabelaArredondamento/view endpoint accepts an id parameter that is concatenated into a SQL query without proper sanitization or parameterization. Public research describes the issue as a blind time-based SQL injection. Attackers infer query results by measuring response delays triggered by injected payloads such as pg_sleep() or SLEEP() functions. The exploit operates at a low privilege level, meaning any authenticated user with access to the module can trigger the flaw.

Root Cause

The root cause is the lack of input validation and parameterized queries when processing the id HTTP parameter. The application directly embeds attacker-controlled input into SQL statements executed by the backend database. This permits injection of arbitrary SQL syntax and conditional logic that the database engine interprets and executes.

Attack Vector

Exploitation occurs over the network against the i-Educar web interface. An authenticated attacker sends a crafted request to /module/TabelaArredondamento/view with a malicious payload in the id query parameter. Because the technique is blind and time-based, attackers extract data character-by-character by observing response latency. No user interaction is required beyond the attacker's session. See the GitHub PoC for CVE-2025-9607 and the SQL Injection technical write-up for detailed exploitation steps.

Detection Methods for CVE-2025-9607

Indicators of Compromise

HTTP requests to /module/TabelaArredondamento/view containing SQL keywords such as SLEEP, pg_sleep, UNION, SELECT, or comment sequences (--, /*) in the id parameter
Abnormally long response times for requests to the TabelaArredondamento endpoint, indicating successful time-based injection
Repeated requests from a single session that iterate over the id parameter with incrementing payloads
Database error messages or stack traces referencing the TabelaArredondamento module in application logs

Detection Strategies

Deploy web application firewall (WAF) rules that detect SQL injection patterns targeting the id parameter on i-Educar endpoints
Enable database query logging and alert on queries containing time-delay functions originating from the i-Educar application user
Inspect HTTP access logs for non-numeric or URL-encoded values in the id parameter of TabelaArredondamento requests

Monitoring Recommendations

Forward i-Educar application and database logs to a centralized SIEM for correlation against authenticated user sessions
Baseline normal response times for the TabelaArredondamento endpoint and alert on statistical deviations
Monitor authenticated user accounts for unusual access patterns to administrative or configuration modules

How to Mitigate CVE-2025-9607

Immediate Actions Required

Restrict access to the /module/TabelaArredondamento/view endpoint to trusted administrative users only
Review authentication logs for unauthorized or suspicious access to the TabelaArredondamento module
Deploy WAF signatures blocking SQL injection payloads targeting the id parameter
Audit the i-Educar database for unauthorized read or modification activity originating from the application service account

Patch Information

No vendor patch has been referenced in the NVD entry at the time of publication. Administrators should monitor the Portabilis i-Educar GitHub repository for upstream security releases addressing the TabelaArredondamento module. Refer to VulDB entry #321785 for additional advisory tracking.

Workarounds

Apply network-level access controls limiting i-Educar administrative modules to internal management networks or VPN
Implement application-layer input validation rejecting non-integer values in the id parameter at a reverse proxy
Reduce the privilege level of the i-Educar database service account to the minimum required, limiting impact of successful injection
Enable prepared statements or parameterized queries in custom forks of i-Educar code that touch the affected module

bash

# Example nginx reverse proxy rule rejecting non-numeric id values
location /module/TabelaArredondamento/view {
    if ($arg_id !~ "^[0-9]+$") {
        return 400;
    }
    proxy_pass http://ieducar_backend;
