Android Bad Practices: Just Provider writePermission Defined

Java/JSP

Abstract

O programa declara um provedor de conteúdo apenas com a writePermission definida.

Explanation

Embora seja uma boa ideia definir permissões separadas de leitura e gravação para provedores de conteúdo, definir apenas a writePermission pode ser enganoso. Devido à natureza do SQL, gerar somente consultas verdadeiras de gravação é geralmente impossível: mesmo quando o usuário não tem acesso direto aos dados, um invasor pode reconstruir os dados armazenados manipulando a cláusula where.

Exemplo: Veja a seguir um exemplo de um provedor de conteúdo declarado somente com a writePermission.

 <provider android:name=".ContentProvider" android:writePermission="content.permission.WRITE_CONTENT"/>
