Upload irrestrito de arquivo com tipo perigoso

Ocorre quando a aplicação aceita upload de arquivos sem validar adequadamente o tipo ou extensão, permitindo que um atacante envie executáveis, scripts ou outros arquivos maliciosos. O risco é grave: o arquivo pode ser armazenado em local acessível pela web, executado pelo servidor, ou baixado e executado pela vítima.

Ejemplo

Um formulário de perfil aceita qualquer arquivo como 'foto', sem verificação. Alguém faz upload de um .exe ou .php; se salvo em pasta pública e com permissões erradas, o arquivo pode ser executado pelo servidor ou baixado por outros usuários.

Cómo mitigar

Valide a extensão e o tipo MIME no servidor (nunca apenas no cliente), rejeite extensões perigosas explicitamente, armazene uploads fora da raiz web ou sem permissão de execução, e considere renomear arquivos removendo extensão original. Idealmente, converta imagens para formatos seguros (PNG/JPG) após upload.
