WeGIA is a web manager for charitable institutions. Prior to version 3.6.6, a critical SQL injection vulnerability exists in the WeGIA application. The remover_produto_ocultar.php script uses extract($_REQUEST) to populate local variables and then directly concatenates these variables into a SQL query executed via PDO::query. This allows an authenticated (or auth-bypassed) attacker to execute arbitrary SQL commands. This can be used to exfiltrate sensitive data from the database or, as demonstrated in this PoC, cause a time-based delay (denial of service). This vulnerability is fixed in 3.6.6.
