界: Input Validation and Representation

輸入驗證和表示法問題是由中繼字元、替代編碼和數值表示法引起的。信任輸入會導致安全問題。問題包括：「Buffer Overflows」、「Cross-Site Scripting」攻擊、「SQL Injection」及其他許多問題。

Spring Beans Injection

Java/JSP

Abstract

載入使用者控制的 Bean 定義資源，可讓攻擊者在伺服器上執行任意程式碼、濫用應用程式邏輯和/或造成阻斷服務。

Explanation

Spring 可讓開發人員從包含本機檔案和遠端 URL 在內的多個資源載入 Bean 定義。如果攻擊者能夠控制 Bean 定義資源的內容，便可以插入惡意 Bean 定義，在初始化時執行任意程式碼。

範例：以下範例會從使用者控制的位置載入 Bean 定義資源：


String beans = getBeanDefinitionFromUser();
GenericApplicationContext ctx = new GenericApplicationContext();
XmlBeanDefinitionReader xmlReader = new XmlBeanDefinitionReader(ctx);
xmlReader.loadBeanDefinitions(new UrlResource(beans));
ctx.refresh();
