Injeção de script

Ocorre quando a aplicação constrói e executa código (JavaScript, Python, shell, etc.) usando dados não validados fornecidos pelo usuário. O atacante consegue injetar comandos arbitrários que serão executados com os privilégios da aplicação, comprometendo a segurança e integridade do sistema.

Exemplo

Um formulário que avalia expressões matemáticas recebidas do usuário: se a entrada é concatenada direto em um eval() ou equivalente, um atacante pode passar `__import__('os').system('rm -rf /')` em vez de uma expressão legítima, executando comandos do sistema.

Como mitigar

Nunca execute código construído a partir de entrada do usuário. Use parsers/validadores que aceitam apenas formatos esperados (whitelist), sandboxes para execução controlada, ou bibliotecas seguras que não avaliam código dinâmico. Se inevitável, isole rigidamente o ambiente de execução.
