界: API Abuse
API 就像是呼叫者與被呼叫者之間簽訂的規定。最常見的 API 濫用形式是由呼叫者這一當事方未能遵守此規定所造成的。例如,如果程式在呼叫 chroot() 後無法呼叫 chdir(),即違反規範如何以安全方式變更使用中根目錄的規定。程式庫濫用的另一個好例子是期待被呼叫者向呼叫者傳回值得信賴的 DNS 資訊。在這種情況下,呼叫者是透過對其行為做出某些假設 (傳回值可用於驗證目的) 來濫用被呼叫者 API。另一方也可能違反呼叫者與被呼叫者間的規定。例如,如果編碼器衍生出子類別 SecureRandom 並傳回一個非隨機值,則違反了規定。
Password Management: Weak Redundancy
Abstract
出於密碼確認目的,新密碼應提供兩次而不是提供複製的密碼。
Explanation
更改密碼或建立新使用者帳戶,通常需要提供兩次新密碼以進行確認。傳遞複製的密碼而不是傳遞兩次密碼,會導致 API 無法確認使用者是否沒有輸入錯誤的密碼,而規避密碼確認的安全機制。
範例 1:
範例 1:
String password=request.getParameter("password");
...
DefaultUser user = (DefaultUser) ESAPI.authenticator().createUser(username, password, password);
