Technical details
WeGIA versions before 3.9.2 contain an authorization bypass in the password change flow caused by two design flaws. First, the alterarSenha method in FuncionarioControle.php is unconditionally excluded from permission checks in controle/control.php (line 84), allowing any authenticated user to invoke it. Second, the method can be routed via the redir parameter to call verificarSenhaConfig() instead of verificarSenha(), which skips old password verification and only validates password complexity and confirmation. An attacker with any valid session (temporary or compromised) can POST to /controle/control.php with metodo=alterarSenha, redir=alterar_senha.php, and a new password to permanently change the target account's credentials without authentication. The fix is available in version 3.9.2 and later.
