Upload sem restrição de arquivo com tipo perigoso

Ocorre quando uma aplicação aceita upload de arquivos sem validar adequadamente seu tipo, extensão ou conteúdo. Um atacante pode enviar executáveis, scripts ou outros arquivos maliciosos, que serão armazenados ou executados no servidor, comprometendo sua integridade e segurança.

Example

Um formulário de perfil aceita qualquer arquivo como 'foto do usuário' sem checar extensão ou MIME type. Um atacante envia um arquivo .exe ou .php renomeado como .jpg, que é salvo no diretório web e posteriormente executado quando acessado, permitindo execução de código remoto.

How to mitigate

Valide uploads checando MIME type real (não apenas extensão), restrinja tipos permitidos de forma explícita, armazene arquivos fora da raiz web, desabilite execução de scripts no diretório de upload e considere usar vírus scanner. Implemente whitelist rigorosa, nunca blacklist.
