CVE-2025-53946: SQL Injection Vulnerability in `id_fichamedica` Parameter on `profile_paciente.php` Endpoint

CVE Publication: https://www.cve.org/CVERecord?id=CVE-2025-53946

Summary

A SQL Injection vulnerability was discovered in the id_fichamedica parameter of the /html/saude/profile_paciente.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 id_fichamedica parameter. As a result, specially crafted SQL payloads are interpreted directly by the backend database.

Impact

Unauthorized access to sensitive data (e.g., users, passwords, logs).
Database enumeration (schemas, tables, users, versions).

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.
