Upload irrestrito de arquivo com tipo perigoso

A aplicação aceita upload de arquivos sem validar adequadamente o tipo ou extensão, permitindo que um atacante envie executáveis, scripts ou outros arquivos maliciosos que serão armazenados ou executados no servidor. O risco aumenta se o arquivo for salvo em diretório acessível pela web ou em local onde será processado automaticamente.

Exemplo

Um sistema de upload de 'fotos de perfil' verifica apenas o tamanho do arquivo, mas não valida a extensão. Um atacante envia um arquivo .php disfarçado de imagem; se salvo em /uploads/ acessível via web, ele consegue executar código PHP no servidor ao acessar a URL direta.

Como mitigar

Valide extensões contra uma lista branca (whitelist) de tipos permitidos, verifique a assinatura do arquivo (magic bytes) e não confie apenas no Content-Type do cliente. Armazene uploads fora do diretório web ou configure o servidor para não executar scripts no diretório de uploads.
