Fallos del tipo CWE-184
245 resultadosLista incompleta de entradas bloqueadas
Ocorre quando o desenvolvedor cria uma lista de padrões ou caracteres proibidos, mas deixa de fora alguns que também deveriam estar ali. Atacantes exploram as entradas não bloqueadas para contornar a validação e injetar código malicioso ou dados malformados.
Ejemplo
Um formulário bloqueia caracteres como '<' e '>' para prevenir XSS, mas esquece de bloquear aspas duplas e eventos JavaScript embutidos. Um atacante injeta onclick="alert('pwned')" e a validação deixa passar.
Cómo mitigar
Use abordagem whitelist (aceitar só o que é válido) em vez de blacklist (bloquear o que é ruim). Se precisar de blacklist, revise frequentemente a lista e teste contra vetores conhecidos. Melhor ainda: sanitize a entrada conforme o contexto onde será usada (HTML, SQL, URL, etc).
