Injeção de script

A aplicação executa código dinâmico (JavaScript, Python, etc.) construído a partir de entrada do usuário sem validação ou sanitização adequada. Um atacante injeta comandos maliciosos que são interpretados e executados pelo servidor ou navegador como se fossem parte legítima do programa.

Ejemplo

Um formulário de contato concatena o nome do usuário diretamente em um script JavaScript enviado ao navegador: `<script>var usuario = '` + entrada_usuario + `';</script>`. Se o usuário envia `'; alert('xss'); //`, o navegador executa o alerta indesejado.

Cómo mitigar

Nunca construa código dinâmico a partir de entrada de usuário. Use APIs seguras (como `JSON.parse()` ao invés de `eval()`, ou templates com escape automático), valide e sanitize rigorosamente todas as entradas, e aplique listas brancas de caracteres permitidos quando possível.
