Manipulação inadequada de dados altamente compactados (amplificação de dados)

Ocorre quando uma aplicação processa dados compactados (ZIP, GZIP, etc.) sem validar ou limitar o tamanho descompactado, permitindo que um arquivo pequeno se expanda para gigabytes na memória. Um atacante envia um arquivo malicioso que causa consumo excessivo de CPU, memória ou disco, derribando o serviço.

Example

Um servidor aceita uploads de arquivos compactados para backup sem verificar o tamanho final. Um arquivo de 10 MB compactado se descompacta para 10 GB, esgotando a memória disponível e travando o servidor. Esse é o ataque 'zip bomb' clássico.

How to mitigate

Estabeleça limites: defina um tamanho máximo aceitável para dados descompactados antes de processar, implemente timeouts de descompactação, e monitore consumo de memória durante a expansão. Valide a integridade e origem dos arquivos compactados recebidos.
