CVE-2025-10012: SQL Injection (Blind Time-Based) Vulnerability in ref_cod_aluno Parameter on educar_historico_escolar_lst.php Endpoint

CVE Publication: https://www.cve.org/CVERecord?id=CVE-2025-10012

Summary

A SQL Injection vulnerability was discovered in the ref_cod_aluno parameter of the educar_historico_escolar_lst.php endpoint. This issue allows any unauthenticated attacker to inject arbitrary SQL queries, potentially leading to unauthorized data access or further exploitation depending on database configuration.

Details

The application fails to properly sanitize user-supplied input in the ref_cod_aluno parameter. As a result, specially crafted SQL payloads are interpreted directly by the backend database.

This payload introduces a time delay, demonstrating the ability to execute arbitrary SQL queries.

Observe the time delay in the server response, indicating the successful execution of the SQL payload.

Impact

• Unauthorized access to sensitive data (e.g., users, passwords, logs).
• Database enumeration (schemas, tables, users, versions).
• Escalation to RCE depending on DB configuration (e.g., xp_cmdshell, UDFs).
• Full compromise of the application if chained with other vulnerabilities.
• This issue affects all users and environments, as it does not require authentication and is reachable via a public endpoint.
