Segurança de software não é o mesmo que software de segurança. Aqui, estamos interessados em tópicos como autenticação, controle de acesso, confidencialidade, criptografia e gestão de privilégios.
Access Control: Case-Insensitive Package Name Comparison
Abstract
Os aplicativos comparam um pacote do Android com um valor controlado pelo usuário de uma maneira que não diferencia maiúsculas de minúsculas, o que pode permitir que invasores ignorem os controles de acesso com base nos nomes dos pacotes.
Explanation
No Android, os nomes de pacotes diferenciam maiúsculas de minúsculas e, portanto, devem ser comparados de maneira diferenciada de maiúsculas e minúsculas. Um aplicativo malicioso pode compartilhar um pacote semelhante com letras maiúsculas diferentes, permitindo que ele ignore o controle de acesso.
Exemplo 1: O código a seguir executa uma comparação de sequência de caracteres insegura para fins de controle de acesso:
Exemplo 1: O código a seguir executa uma comparação de sequência de caracteres insegura para fins de controle de acesso:
public boolean isTrusted(String paramString) {
if (this._applicationContext.getPackageName().equalsIgnoreCase(paramString)) {
return true;
}
