界: Encapsulation

封裝是要劃定清楚的界限。在網頁瀏覽器中,這可能意味著確保您的行動程式碼不會被其他行動程式碼濫用。在伺服器上,這可能意味著區分經過驗證的資料與未經驗證的資料、區分一個使用者的資料與另一個使用者的資料,或區分允許使用者查看的資料與不允許查看的資料。

Abstract
自動產生的 JavaScript Proxy 檔案可能會洩露系統資訊,因為這些檔案會列出所有顯示方法和中樞 (Hub)。
Explanation
如果您不希望 JavaScript Proxy 檔案中包含每個使用者的所有中樞和方法,您可以停用自動產生檔案。如果您有多個中樞和方法,但不希望每位使用者都注意所有方法時,您可以選擇此選項。

Abstract
啟用 Spring Boot Actuator 可能會揭露系統資料和除錯資訊,這些資訊有助於攻擊者暸解系統和制訂攻擊計畫。
Explanation
Spring Boot Actuator 可讓使用者監控應用程式並與之互動。存在不同的內建 Actuator 會透過 HTTP 端點、JMX 甚至透過遠端 Shell (SSH 或 Telnet) 暴露系統資料和除錯資訊。攻擊者可能會受益於此資訊,以暸解系統並收集可用於攻擊應用程式的資訊。

Abstract
顯示系統資料或除錯資訊有助於攻擊者瞭解系統並制訂攻擊計畫。
Explanation
當系統資料或除錯資訊透過輸出串流或記錄功能離開程式時,會發生資訊洩漏。

在此案例中,Struts 2 Config Browser 設定於 maven pom.xml 檔案中,所以可以隨應用程式提供使用及部署。

Config Browser 外掛程式是一種除錯工具,可協助檢視執行階段時的應用程式組態。當除錯的問題可能與組態問題有關,但可能會暴露過多詳細資料而可能幫助攻擊者對應並建立應用程式模型時,這項工具將非常有用。

Abstract
將可信賴和不可信賴的資料混合在同一資料結構中,這麼做會讓程式設計師誤信未經驗證的資料。
Explanation
您可以將信賴界線想像成一條透過程式所畫出的分界線。在分界線的一側,資料是不可信賴的。而在線的另一側,則會假設資料是可信賴的。驗證邏輯的目的是允許資料安全地跨越可信賴界線--從不可信賴的一側移動到可信賴的一側。

當一個程式把可信賴和不可信賴間的界線弄得模糊不清時,就會發生 Trust Boundary Violation 的問題。發生這種錯誤最普遍的方式就是,將可信賴的和不可信賴的資料混合在同一個資料結構中。
範例 1:以下 C# 程式碼接受 HTTP 要求,並在檢查以確認使用者已通過驗證之前,在 HTTP 工作階段物件中儲存 usrname 參數。


usrname = request.Item("usrname");
if (session.Item(ATTR_USR) == null) {
session.Add(ATTR_USR, usrname);
}


如果沒有建立完善且妥善維護的信賴界線,程式設計師將不可避免地混淆哪些資料經過驗證以及那些資料尚未經過驗證。這種混淆狀況最後會導致在沒有先行驗證某些資料的情況下,就使用這些資料。

Abstract
將可信賴和不可信賴的資料混合在同一資料結構中,這麼做會讓程式設計師誤信未經驗證的資料。
Explanation
您可以將信賴界線想像成一條透過程式所畫出的分界線。在分界線的一側,資料是不可信賴的。而在線的另一側,則會假設資料是可信賴的。驗證邏輯的目的是允許資料安全地跨越可信賴界線--從不可信賴的一側移動到可信賴的一側。

當一個程式把可信賴和不可信賴間的界線弄得模糊不清時,就會發生 Trust Boundary Violation 的問題。發生這種錯誤最普遍的方式就是,將可信賴的和不可信賴的資料混合在同一個資料結構中。

範例 1:以下 Java 程式碼接受 HTTP 要求,並在檢查以確認使用者已通過驗證之前,在 HTTP 工作階段物件中儲存 usrname 參數。


usrname = request.getParameter("usrname");
if (session.getAttribute(ATTR_USR) != null) {
session.setAttribute(ATTR_USR, usrname);
}


如果沒有建立完善且妥善維護的信賴界線,程式設計師將不可避免地混淆哪些資料經過驗證以及那些資料尚未經過驗證。這種混淆狀況最後會導致在沒有先行驗證某些資料的情況下,就使用這些資料。

Abstract
將可信賴和不可信賴的資料混合在同一資料結構中,這麼做會讓程式設計師誤信未經驗證的資料。
Explanation
您可以將信賴界線想像成一條透過程式所畫出的分界線。在分界線的一側,資料是不可信賴的。而在線的另一側,則會假設資料是可信賴的。驗證邏輯的目的是允許資料安全地跨越可信賴界線--從不可信賴的一側移動到可信賴的一側。

當一個程式把可信賴和不可信賴間的界線弄得模糊不清時,就會發生 Trust Boundary Violation 的問題。發生這種錯誤最普遍的方式就是,將可信賴的和不可信賴的資料混合在同一個資料結構中。

範例 1:以下 Python 程式碼接受 HTTP 要求,並在檢查以確認使用者已通過驗證之前,在 HTTP 工作階段物件中儲存 username 參數。


uname = request.GET['username']
request.session['username'] = uname


如果沒有建立完善且妥善維護的信賴界線,程式設計師將不可避免地混淆哪些資料經過驗證以及那些資料尚未經過驗證。這種混淆狀況最後會導致在沒有先行驗證某些資料的情況下,就使用這些資料。

Abstract
該程式從 public 存取方法中回傳 private 陣列變數,因此違反了行動程式碼的安全編碼原則。
Explanation
程式可以從 public 存取方法中回傳 private 陣列變數,透過此方式,您可以呼叫程式碼修改該陣列的內容,這可以輕易地取得陣列 public 存取權限,並阻止程式設計師將它設為 private 的計畫。

範例 1:下列 Java Applet 程式碼錯誤地從 public 存取方法回傳 private 陣列變數。


public final class urlTool extends Applet {
private URL[] urls;
public URL[] getURLs() {
return urls;
}
...
}


行動程式碼,在這個示例中也就是 Java Applet,是一種跨網路傳輸,並且可在遠端機器上執行的程式碼。因為行動程式碼的編寫者很難控制他們編寫的程式碼的執行環境,所以在安全上提出特別的要求是有必要的。其中一個最大的環境威脅在於,行動程式碼可以伴隨著其他的潛在惡意的行動程式碼一起運作。因為所有主流的瀏覽器會使用同一個 JVM 執行來自多個資源的程式碼,所以許多安全規範都把注意力集中在可以存取您的程式碼運行的 JVM 攻擊者,避免他們竄改您的物件狀態和運作方式。

Abstract
若 Applet 在不可信賴的環境中執行 JDBC 資料庫作業,可能會導致資料庫憑證外洩。
Explanation
依照預設,Java Applet 可開啟資料庫通往 Applet 下載來源伺服器的連線。在受信任的環境中,這項行為是受到認可的,不過在不可信賴的環境中,攻擊者可能會使用該 Applet 來獲取資料庫憑證,最後便能直接進入資料庫。
範例 1:下列程式碼顯示 Hardcoded Database Password 如何在 Applet 中進行使用。

public class CustomerServiceApplet extends JApplet
{
public void paint(Graphics g)
{
...
conn = DriverManager.getConnection ("jdbc:mysql://db.example.com/customerDB", "csr", "p4ssw0rd");
...


由於 Applet 程式碼下載到用戶端,因此具有強制編碼 JDBC 憑證的 Applet 使用者可輕易發現憑證。此外,若透過未加密的通道進行資料庫連線,則任何能夠攔截網路流量的使用者也可取得憑證。最後,若允許使用者直接連線到資料庫,可公開存取的資料庫伺服器將顯露無遺,這樣一來,攻擊者便會把該資料庫做為直接網路攻擊的目標。

Abstract
程式違反行動程式碼的安全編碼原則,因為使用了 inner class。
Explanation
由於 Inner class 轉譯成 Java 位元程式碼的方式,導致它會帶來一些安全性問題。在 Java 原始程式碼中,inner class 只能由一個封裝類別來聲明它是可存取的,但是 Java 位元組程式碼並沒有 inner class 的概念,所以編譯器必須把一個 inner class 的聲明轉換成與 package 有同等地位的類別 (有權存取來源外部類別)。由於 inner class 可以存取在封裝類別中的 private 欄位,一旦某個 inner class 成為在位元組碼中的同等類別時,此編譯器會把 inner class 所存取的 private 欄位轉換成 protected 欄位,這一點具有潛在的危險性。

範例 1:以下的 Java Applet 程式碼使用 inner class 的方法錯誤。


public final class urlTool extends Applet {
private final class urlHelper {
...
}
...
}


行動程式碼,在這個示例中也就是 Java Applet,是一種跨網路傳輸,並且可在遠端機器上執行的程式碼。因為行動程式碼的編寫者很難控制他們編寫的程式碼的執行環境,所以在安全上提出特別的要求是有必要的。其中一個最大的環境威脅在於,行動程式碼可以伴隨著其他的潛在惡意的行動程式碼一起運作。因為所有主流的瀏覽器會使用同一個 JVM 執行來自多個資源的程式碼,所以許多安全規範都把注意力集中在可以存取您的程式碼運行的 JVM 攻擊者,避免他們竄改您的物件狀態和運作方式。

Abstract
程式聲明 finalize() 方法 public,因此違反了行動程式碼的安全編碼原則。
Explanation
finalize() 的執行中呼叫 super.finalize(),否則請勿明確地呼叫 finalize。在行動程式碼中,易於發生錯誤的手動垃圾收集操作會威脅系統的安全,由於 finalize() 的聲明中包含對 public 的存取,因此會造成攻擊者的惡意呼叫。如果您按照 finalize() 的設計來使用它,則應首先聲明 finalize() 包含 protected 的存取權。

範例 1:下列 Java Applet 程式碼錯誤地聲明了一個 public finalize() 方法。


public final class urlTool extends Applet {
public void finalize() {
...
}
...
}


行動程式碼,在這個示例中也就是 Java Applet,是一種跨網路傳輸,並且可在遠端機器上執行的程式碼。因為行動程式碼的編寫者很難控制他們編寫的程式碼的執行環境,所以在安全上提出特別的要求是有必要的。其中一個最大的環境威脅在於,行動程式碼可以伴隨著其他的潛在惡意的行動程式碼一起運作。因為所有主流的瀏覽器會使用同一個 JVM 執行來自多個資源的程式碼,所以許多安全規範都把注意力集中在可以存取您的程式碼運行的 JVM 攻擊者,避免他們竄改您的物件狀態和運作方式。

Abstract
程式聲明陣列 publicfinalstatic,因此違反了行動程式碼的安全編碼原則。
Explanation
在大多數情況下,把一個陣列聲明為 publicfinalstatic 是一個錯誤 (bug)。由於陣列是一個可變的物件,因此 final 限制會要求陣列物件本身只能被分配一次,但是不能保證陣列的元件的值也是如此。由於陣列是公用的,因此惡意的程式可以變更儲存在陣列中的值。所以,在大多數情況下,應該將陣列設定為 private

範例 1:下列 Java Applet 程式碼錯誤地將一個陣列聲明為 publicfinalstatic


public final class urlTool extends Applet {
public final static URL[] urls;
...
}


行動程式碼,在這個示例中也就是 Java Applet,是一種跨網路傳輸,並且可在遠端機器上執行的程式碼。因為行動程式碼的編寫者很難控制他們編寫的程式碼的執行環境,所以在安全上提出特別的要求是有必要的。其中一個最大的環境威脅在於,行動程式碼可以伴隨著其他的潛在惡意的行動程式碼一起運作。因為所有主流的瀏覽器會使用同一個 JVM 執行來自多個資源的程式碼,所以許多安全規範都把注意力集中在可以存取您的程式碼運行的 JVM 攻擊者,避免他們竄改您的物件狀態和運作方式。
