Weaknesses of type CWE-362

Condição de corrida

Ocorre quando dois ou mais processos/threads acessam e modificam um recurso compartilhado simultaneamente, sem sincronização adequada. O resultado final depende da ordem e timing das operações, criando estados inconsistentes que podem ser explorados para contornar controles de segurança, corromper dados ou ganhar privilégios.

Example

Um aplicativo verifica se um arquivo existe e tem permissão de leitura (check), depois o abre (use). Um atacante, entre o check e o use, substitui o arquivo por um link simbólico apontando para /etc/passwd. O programa abre inadvertidamente um arquivo sensível que não deveria acessar.

How to mitigate

Use primitivas de sincronização (mutexes, semáforos, locks) para serializar acessos críticos. Quando possível, use operações atômicas do SO (ex: open com flags O_EXCL) que combinam check e use em uma única syscall indivisível. Validar estado antes de cada operação crítica, não apenas uma vez.
