WeGIA has a SQL Injection in DespachoDAO.php via id_memorando parameter

WeGIA is a Web manager for charitable institutions. Prior to 3.6.9, WeGIA (Web gerenciador para instituições assistenciais) contains a SQL injection vulnerability in dao/memorando/DespachoDAO.php. The id_memorando parameter is extracted from $_REQUEST without validation and directly interpolated into SQL queries, allowing any authenticated user to execute arbitrary SQL commands against the database. This vulnerability is fixed in 3.6.9.
