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。

Denial of Service

Abstract
攻擊者會摧毀程式或者讓合法的使用者無法使用程式。
Explanation
攻擊者能夠對應用程式發送大量要求，使其拒絕對合法使用者的服務，但大量攻擊形式通常會在網路層便被排除掉。較嚴重的問題是可讓攻擊者使用少量要求便可超載應用程式的錯誤 (bug)。此種錯誤可讓攻擊者去指定要求系統資源使用的數量，或是他們會持續使用這些系統資源而造成資源耗竭的時間。

範例 1：以下程式碼允許使用者指定目前工作程序進入睡眠的時間長度。若指定較大的數字，攻擊者可能無限期地佔用工作程序。

Abstract
應用程式使用用戶端的遠端 IP 位址來建立 RateLimitPartition。
Explanation
根據用戶端的 IP 位址建立 RateLimitPartitions 會使應用程式容易遭受採用 IP Source Address Spoofing 的 Denial of Service 攻擊。

範例 1：在以下範例中，GetTokenBucketLimiter() 方法使用遠端 IP 位址 (RemoteIpAddress) 作為建立 RateLimitPartition 時的分割區索引鍵：


...
builder.Services.AddRateLimiter(limiterOptions => {
    limiterOptions.GlobalLimiter = PartitionedRateLimiter.Create<HttpContext, IPAddress>(context => {

        IPAddress? ip = context.Connection.RemoteIpAddress;

        return RateLimitPartition.GetTokenBucketLimiter(ip!, _ =>
            new TokenBucketRateLimiterOptions
            {
                TokenLimit = 7
            });
    });
});

Abstract
攻擊者會摧毀程式或者讓合法的使用者無法使用程式。
Explanation
攻擊者能夠對應用程式發送大量要求，使其拒絕對合法使用者的服務，但大量攻擊形式通常會在網路層便被排除掉。較嚴重的問題是可讓攻擊者使用少量要求便可超載應用程式的錯誤 (bug)。此種錯誤可讓攻擊者去指定要求系統資源使用的數量，或是他們會持續使用這些系統資源的時間。

範例 1：以下程式碼允許使用者指定執行緒進入睡眠的時間長度。若指定較大的數字，攻擊者可能無限期地佔用執行緒。因此，僅需要少數要求，攻擊者就可能耗盡應用程式的執行緒池。


  int usrSleepTime = Integer.parseInt(usrInput);
  Thread.sleep(usrSleepTime);
範例 2：以下程式碼會從 zip 檔案讀取字串。因為它使用 readLine() 方法，它會讀取大量的輸入。攻擊者可能利用此程式碼產生 OutOfMemoryException 或消耗大量記憶體，讓程式花費更多時間來執行記憶體回收或者在一些後續作業中耗盡記憶體。


  InputStream zipInput = zipFile.getInputStream(zipEntry);
  Reader zipReader = new InputStreamReader(zipInput);
  BufferedReader br = new BufferedReader(zipReader);
  String line = br.readLine();

範例 2：以下程式碼會寫入檔案。以下程式碼會寫入檔案。由於檔案可能會不斷地寫入和重新寫入，直到使用者代理程式將其關閉為止，因此可能需要分析檔案內容的磁碟配額、IO 頻寬以及處理序會受到影響。

Abstract
攻擊者會摧毀程式或者讓合法的使用者無法使用程式。
Explanation
攻擊者能夠對應用程式發送大量要求，使其拒絕對合法使用者的服務，但大量攻擊形式通常會在網路層便被排除掉。較嚴重的問題是可讓攻擊者使用少量要求便可超載應用程式的錯誤 (bug)。此種錯誤可讓攻擊者去指定要求系統資源使用的數量，或是他們會持續使用這些系統資源的時間。

範例 1：以下程式碼允許使用者指定執行緒進入睡眠的時間長度。若指定較大的數字，攻擊者可能無限期地佔用執行緒。因此，僅需要少數要求，攻擊者就可能耗盡應用程式的執行緒池。


  Kernel.sleep(user_input)
範例 2：以下程式碼會從檔案中讀取字串。因為它使用 readline() 方法，且無需指定限制，所以它會讀取大量的輸入。攻擊者可能利用此程式碼使程序暫停，同時耗用越來越多的記憶體，直到可能完全耗盡記憶體。


  fd = File.new(myFile)
  line = fd.readline
