Privacy Violation: Android Insecure Indexing

Java/JSP

Abstract

创建私有或敏感文档的搜索索引可能会损害用户隐私。

Explanation

不安全的索引会威胁到网站和移动应用程序的数据机密性，而这些网站和移动应用程序需要通过索引来实现高效的全文搜索；在 Android 搜索引擎索引的文档中包含私有或机密数据，这可能会导致有关数据存在和内容的信息泄露。在索引过程中，会收集和存储信息。攻击者稍后可以检索到此信息（尽管并不容易），通常是通过对 Android 移动设备上的搜索工具进行一系列查询。

AppSearch 库是一个高性能的 Android 设备端搜索解决方案，它是数据索引的一个典型示例，特别是当某个应用程序有助于在设备上建立系统范围中央索引（称为平台存储）时。中央索引内的数据访问仅限于应用程序贡献的数据，以及其他应用程序通过适当的权限授予显式共享的数据。如果错误地或意外地使用此过程对特定机密文档建立了索引，则可能会因允许搜索该文档而导致隐私侵犯。

示例 1：以下代码显示的示例展示了如何使用 AppSearch 库在 Android 上对私有文档建立索引。该文档包含私有数据，这些数据应在索引过程中隐藏，且不允许 AppSearch 代码访问。



...
// Document object to index
val doc = Doc(
    namespace="user1",
    id="noteId",
    score=10,
    text="This document contains private data"
)
// Adding document object to AppSearch index
val putRequest = PutDocumentsRequest.Builder().addDocuments(doc).build()
