Condição de corrida (Race Condition)

Ocorre quando múltiplas threads ou processos acessam e modificam um recurso compartilhado (arquivo, variável, banco de dados) sem sincronização adequada. O resultado final depende da ordem de execução, que é imprevisível, permitindo que um atacante manipule o timing para causar comportamento não autorizado ou corrupção de dados.

Ejemplo

Um aplicativo web verifica se um usuário tem saldo antes de debitar uma transação, mas não mantém lock entre a verificação e o débito. Um atacante dispara dois saques simultâneos da mesma conta; ambos passam na validação antes que qualquer um tenha atualizado o saldo, resultando em saque maior que o disponível.

Cómo mitigar

Use mecanismos de sincronização (mutex, semáforos, locks) ao acessar recursos compartilhados, ou implemente operações atômicas que garantam que verificação e modificação ocorram como uma única unidade indivisível. Em bases de dados, use transações com isolamento adequado (SERIALIZABLE quando necessário).
