Abstract
空白的 HMAC 金鑰可能會導致無法輕易修正的系統安全性問題。
Explanation
使用空白 HMAC 金鑰絕對不是個好方法。HMAC 的加密強度取決於秘密金鑰的長度,該秘密金鑰用於計算和驗證訊息驗證值。使用空的金鑰會減弱 HMAC 函數的加密強度。
範例 1:以下程式碼使用空白金鑰來計算 HMAC:

...
DATA: lo_hmac TYPE Ref To cl_abap_hmac,
Input_string type string.

CALL METHOD cl_abap_hmac=>get_instance
EXPORTING
if_algorithm = 'SHA3'
if_key = space
RECEIVING
ro_object = lo_hmac.

" update HMAC with input
lo_hmac->update( if_data = input_string ).

" finalise hmac
lo_digest->final( ).

...
Example 1 中所示的程式碼能夠順利執行,但有程式碼存取權的任何人都能看出它使用了空的 HMAC 金鑰。程式發佈後,除非修補此程式,否則可能無法變更空白 HMAC 金鑰。若不懷好意的員工有此資訊的存取權,可能會使用此資訊來危害 HMAC 函數。此外,Example 1 中的程式碼容易受到 forgery 和 key recovery 攻擊。

Abstract
空白的 HMAC 金鑰可能會導致無法輕易修正的系統安全性問題。
Explanation
使用空白 HMAC 金鑰絕對不是個好方法。HMAC 的加密強度取決於秘密金鑰的長度,該秘密金鑰用於計算和驗證訊息驗證值。使用空的金鑰會減弱 HMAC 函數的加密強度。
範例 1:以下程式碼使用空白 HMAC 金鑰來產生 HMAC 雜湊:

...
let hmacKey = "";
let hmac = crypto.createHmac("SHA256", hmacKey);
hmac.update(data);
...
範例 1 中的程式碼能夠順利執行,但有程式碼存取權的任何人都能看出它使用了空的 HMAC 金鑰。程式發佈後,除非修補此程式,否則可能無法變更空白 HMAC 金鑰。若不懷好意的員工有此資訊的存取權,可能會使用此資訊來危害 HMAC 函數。

Abstract
空白的 HMAC 金鑰可能會導致無法輕易修正的系統安全性問題。
Explanation
使用空白 HMAC 金鑰絕對不是個好方法。HMAC 的加密強度取決於秘密金鑰的長度,該秘密金鑰用於計算和驗證訊息驗證值。使用空的金鑰會減弱 HMAC 函數的加密強度。

範例 1:以下程式碼使用空白金鑰來計算 HMAC:

...
digest = OpenSSL::HMAC.digest('sha256', '', data)
...
Example 1 中的程式碼能夠順利執行,但有程式碼存取權的任何人都能看出它使用了空的 HMAC 金鑰。程式發佈後,除非修補此程式,否則可能無法變更空白 HMAC 金鑰。若不懷好意的員工有此資訊的存取權,可能會使用此資訊來危害 HMAC 函數。此外,Example 1 中的程式碼容易受到 forgery 和 key recovery 攻擊。

Abstract
使用以密碼為基礎的金鑰衍生函數所產生的金鑰,並將空白值傳遞給函數做為密碼引數時,可能會導致無法輕易修正系統安全性的問題。
Explanation
將空白值做為密碼引數傳遞給以密碼為基礎的金鑰衍生函數 (PBKDF) 絕對不是個好方法。在此情況下,衍生金鑰將完全以提供的 Salt 為基礎 (使其明顯安全性較低),且會極難修正問題。產生違反規則的程式碼以後,除非修補軟體,否則通常無法變更空白密碼。如果根據空白密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將空白字串做為密碼引數傳遞到加密 PBKDF:


...
Rfc2898DeriveBytes rdb = new Rfc2898DeriveBytes("", salt,100000);
...


不僅任何有程式碼存取權的人都能夠確定這會根據 Empty Password 引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Empty Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Empty Password。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Empty Password 的使用證據。

Abstract
空白密碼用於從以密碼為基礎的金鑰衍生函數 (PBKDF) 產生金鑰。將空白密碼提供給 PBKDF,可能會導致無法輕易修正的系統安全性問題。
Explanation
將空白值做為密碼引數傳遞給以密碼為基礎的金鑰衍生函數 (PBKDF) 絕對不是個好方法。在此情況下,衍生金鑰將完全以提供的 Salt 為基礎 (使其明顯安全性較低),且會極難修正問題。產生違反規則的程式碼以後,除非修補軟體,否則通常無法變更空白密碼。如果根據空白密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將空白字串做為密碼引數傳遞到加密 PBKDF:


...
var encryptor = new StrongPasswordEncryptor();
var encryptedPassword = encryptor.encryptPassword("");
...


不僅任何有程式碼存取權的人都能夠確定這會根據 Empty Password 引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Empty Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Empty Password。若員工有此資訊的存取權,可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Empty Password 的使用證據。

範例 1:以下程式碼將空白字串做為密碼引數傳遞到加密 PBKDF:

salt,

kCCPRFHmacAlgSHA256,

...


不僅任何有程式碼存取權的人都能夠確定這會根據 Empty Password 引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Empty Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Empty Password。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Empty Password 的使用證據。

範例 2:有些低層級 API 可能需要傳遞某些引數的長度,以及本身的引數值,如此函數才能在引數於記憶體中的位置開始讀取許多連續位元組的引數值。以下程式碼會將零做為密碼長度引數傳遞到加密 PBKDF:


...
CCKeyDerivationPBKDF(kCCPBKDF2,
password,
0,
salt,
saltLen
kCCPRFHmacAlgSHA256,
100000,
derivedKey,
derivedKeyLen);
...


在此情況下,即使 password 包含強式、經過適當管理的密碼值,傳遞零的長度也將導致空白、null 或其他意外的弱式密碼值。

Abstract
空白密碼用於從以密碼為基礎的金鑰衍生函數 (PBKDF) 產生金鑰。將空白密碼提供給 PBKDF,可能會導致無法輕易修正的系統安全性問題。
Explanation
將空白值做為密碼引數傳遞給以密碼為基礎的金鑰衍生函數 (PBKDF) 絕對不是個好方法。在此情況下,衍生金鑰將完全以提供的 Salt 為基礎 (使其明顯安全性較低),且會極難修正問題。產生違反規則的程式碼以後,除非修補軟體,否則通常無法變更空白密碼。如果根據空白密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將空白字串做為密碼引數傳遞到加密 PBKDF:


...
$zip = new ZipArchive();
$zip->open("test.zip", ZipArchive::CREATE);
$zip->setEncryptionIndex(0, ZipArchive::EM_AES_256, "");
...


任何有權存取該程式碼的人,都可以判斷出它會根據空白密碼引數產生一或多個加密金鑰。此外,任何擁有基本破解技巧的人,都可以成功存取受違反規定之金鑰保護的任何資源。如果攻擊者還能存取用於根據 Empty Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Empty Password。若員工有此資訊的存取權,可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Empty Password 的使用證據。

Abstract
空白密碼用於從以密碼為基礎的金鑰衍生函數 (PBKDF) 產生金鑰。將空白密碼提供給 PBKDF,可能會導致無法輕易修正的系統安全性問題。
Explanation
將空白值做為密碼引數傳遞給以密碼為基礎的金鑰衍生函數 (PBKDF) 絕對不是個好方法。在此情況下,衍生金鑰將完全以提供的 Salt 為基礎 (使其明顯安全性較低),且會極難修正問題。產生違反規則的程式碼以後,除非修補軟體,否則通常無法變更空白密碼。如果根據空白密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將空白字串做為密碼引數傳遞到加密 PBKDF:


...
CCKeyDerivationPBKDF(CCPBKDFAlgorithm(kCCPBKDF2),
"",
0,
salt,
saltLen,
CCPseudoRandomAlgorithm(kCCPRFHmacAlgSHA256),
100000,
derivedKey,
derivedKeyLen)
...


不僅任何有程式碼存取權的人都能夠確定這會根據 Empty Password 引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Empty Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Empty Password。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Empty Password 的使用證據。

範例 2:有些低層級 API 可能需要傳遞某些引數的長度,以及本身的引數值,如此函數才能在引數於記憶體中的位置開始讀取許多連續位元組的引數值。以下程式碼會將零做為密碼長度引數傳遞到加密 PBKDF:


...
CCKeyDerivationPBKDF(CCPBKDFAlgorithm(kCCPBKDF2),
password,
0,
salt,
saltLen,
CCPseudoRandomAlgorithm(kCCPRFHmacAlgSHA256),
100000,
derivedKey,
derivedKeyLen)
...


在此情況下,即使 password 包含強式、經過適當管理的密碼值,傳遞零的長度也將導致空白、null 或其他意外的弱式密碼值。

Abstract
硬式編碼加密金鑰會導致無法輕易修正的安全性問題。
Explanation
切勿將加密金鑰硬式編碼,因為不僅所有專案開發人員都能看到加密金鑰,也會讓修正問題的工作變得相當困難。程式碼進入生產階段後,只有修補軟體才能變更加密金鑰。如果加密金鑰保護的帳戶遭到入侵,系統的所有者必須在安全性和系統可用性之間做出選擇。

範例 1:以下程式碼會使用硬式編碼加密金鑰執行 AES 加密:


...
Blob encKey = Blob.valueOf('YELLOW_SUBMARINE');
Blob encrypted = Crypto.encrypt('AES128', encKey, iv, input);
...


任何有程式碼存取權的人都能夠看到加密金鑰。發佈應用程式之後,如果沒有軟體修補程式,便無法變更加密金鑰。若員工有此資訊的存取權,可能會使用此資訊來進入並破壞系統。任何攻擊者只要取得權限存取應用程式可執行檔案,就可以擷取加密金鑰值。

Abstract
硬式編碼加密金鑰會導致無法輕易修正的安全性問題。
Explanation
對加密金鑰執行硬式編碼絕對不是明智的想法,因為這不僅可讓所有專案開發人員檢視加密金鑰,而且會讓修正問題的工作變得相當困難。產生程式碼以後,除非修補軟體,否則無法變更加密金鑰。如果加密金鑰所保護的帳戶出現問題,系統的所有者將必須在安全性和可用性之間做出選擇。

範例 1:下列程式碼使用硬式編碼的加密金鑰:


...
<cfset encryptionKey = "lakdsljkalkjlksdfkl" />
<cfset encryptedMsg = encrypt(msg, encryptionKey, 'AES', 'Hex') />
...


任何有程式碼存取權的人都能夠存取加密金鑰。一旦發佈應用程式,除非修補此程式,否則無法變更加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。如果攻擊者能夠存取應用程式的可執行檔,那麼他們就可以擷取加密金鑰值。

Abstract
硬式編碼加密金鑰會導致無法輕易修正的安全性問題。
Explanation
對加密金鑰執行硬式編碼絕對不是明智的想法,因為這不僅可讓所有專案開發人員檢視加密金鑰,而且會讓修正問題的工作變得相當困難。產生程式碼以後,除非修補軟體,否則無法變更加密金鑰。如果加密金鑰所保護的帳戶出現問題,系統的所有者將必須在安全性和可用性之間做出選擇。

範例 1:下列程式碼使用硬式編碼的加密金鑰:


...
var crypto = require('crypto');
var encryptionKey = "lakdsljkalkjlksdfkl";
var algorithm = 'aes-256-ctr';
var cipher = crypto.createCipher(algorithm, encryptionKey);
...


任何有程式碼存取權的人都能夠存取加密金鑰。一旦發佈應用程式,除非修補此程式,否則無法變更加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。如果攻擊者能夠存取應用程式的可執行檔,那麼他們就可以擷取加密金鑰值。

Abstract
Hardcoded Password 會導致難以修正系統的安全性問題。
Explanation
切勿使用 Hardcoded Password。這不僅會將密碼公開給所有的專案開發人員,也會使得修正問題的工作變得異常困難。程式碼進入生產階段後,程式修補可能是變更密碼的唯一方法。如果密碼保護的帳戶出現問題,系統的所有者必須在安全性和可行性之間做出選擇。
範例 1:下列 JSON 使用 Hardcoded Password:


...
{
"username":"scott"
"password":"tiger"
}
...


此配置可能有效,但有配置存取權的任何人都能夠存取密碼。程式發行後,變更密碼為「tiger」的預設使用者帳戶「scott」很困難。任何人只要有此資訊的存取權,就可能使用此資訊來進入並破壞系統。

Abstract
硬式編碼加密金鑰會導致無法輕易修正的安全性問題。
Explanation
對加密金鑰執行硬式編碼絕對不是明智的想法,因為這不僅可讓所有專案開發人員檢視加密金鑰,而且會讓修正問題的工作變得相當困難。產生程式碼以後,除非修補軟體,否則無法變更加密金鑰。如果加密金鑰所保護的帳戶出現問題,系統的所有者將必須在安全性和可用性之間做出選擇。



任何有程式碼存取權的人都能夠存取加密金鑰。一旦發佈應用程式,除非修補此程式,否則無法變更加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。如果攻擊者能夠存取應用程式的可執行檔,那麼他們就可以擷取加密金鑰值。

Abstract
硬式編碼加密金鑰會導致無法輕易修正的安全性問題。
Explanation
對加密金鑰執行硬式編碼絕對不是明智的想法,因為硬式編碼加密金鑰不僅可讓所有專案開發人員檢視加密金鑰,而且會讓修正問題的工作變得相當困難。產生程式碼以後,除非修補軟體,否則無法變更加密金鑰。如果加密金鑰所保護的帳戶出現問題,系統的所有者將必須在安全性和可用性之間做出選擇。

範例 1:下列程式碼使用硬式編碼的加密金鑰:


...
let encryptionKey = "YELLOW_SUBMARINE"
...
範例 2:以下程式碼會使用硬式編碼的加密金鑰執行 AES 加密:


...
CCCrypt(UInt32(kCCEncrypt),
UInt32(kCCAlgorithmAES128),
UInt32(kCCOptionPKCS7Padding),
"YELLOW_SUBMARINE",
16,
iv,
plaintext,
plaintext.length,
ciphertext.mutableBytes,
ciphertext.length,
&numBytesEncrypted)
...


任何有程式碼存取權的人都能夠存取加密金鑰。程式發佈後,除非修補此程式,否則無法變更加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。如果攻擊者能夠存取應用程式的可執行檔,那麼他們就可以擷取加密金鑰值。

Abstract
硬式編碼加密金鑰會導致無法輕易修正的安全性問題。
Explanation
切勿將加密金鑰硬式編碼,因為不僅所有專案開發人員都能看到加密金鑰,也會讓修正問題的工作變得相當困難。程式碼進入生產階段後,只有修補軟體才能變更加密金鑰。如果加密金鑰保護的帳戶遭到入侵,系統的所有者必須在安全性和系統可用性之間做出選擇。

範例 1:以下範例顯示 .pem 檔案內的加密金鑰:

任何有程式碼存取權的人都能夠看到加密金鑰。發佈應用程式之後,除非修補此程式,否則無法變更加密金鑰。若員工有此資訊的存取權,可能會使用此資訊來進入並破壞系統。任何攻擊者只要取得權限存取應用程式可執行檔案,就可以擷取加密金鑰值。

Abstract
硬式編碼加密金鑰會導致無法輕易修正的安全性問題。
Explanation
切勿將加密金鑰硬式編碼,因為不僅所有專案開發人員都能看到加密金鑰,也會讓修正問題的工作變得相當困難。程式碼進入生產階段後,只有修補軟體才能變更加密金鑰。如果加密金鑰保護的帳戶遭到入侵,系統的所有者必須在安全性和系統可用性之間做出選擇。

範例 1:以下範例顯示 Ruby on Rails 組態 secrets.yml 檔案中的加密金鑰:


...
production:
secret_key_base: 0ab25e26286c4fb9f7335947994d83f19861354f19702b7bbb84e85310b287ba3cdc348f1f19c8cdc08a7c6c5ad2c20ad31ecda177d2c74aa2d48ec4a346c40e
...


任何有程式碼存取權的人都能夠看到加密金鑰。發佈應用程式之後,除非修補此程式,否則無法變更加密金鑰。若員工有此資訊的存取權,可能會使用此資訊來進入並破壞系統。任何攻擊者只要取得權限存取應用程式可執行檔案,就可以擷取加密金鑰值。

Abstract
硬式編碼的 HMAC 金鑰可能會導致無法輕易修正的系統安全性問題。
Explanation
將 HMAC 金鑰硬式編碼絕對不是個好方法。HMAC 的加密強度取決於秘密金鑰的保密性,該秘密金鑰用於計算和驗證訊息驗證值。將 HMAC 金鑰硬式編碼,會讓擁有來源存取權的任何人都能檢視它,因此會減弱函數的加密強度。
範例 1:下列程式碼使用硬式編碼的金鑰來計算 HMAC:

...
DATA: lo_hmac TYPE Ref To cl_abap_hmac,
Input_string type string.

CALL METHOD cl_abap_hmac=>get_instance
EXPORTING
if_algorithm = 'SHA3'
if_key = 'secret_key'
RECEIVING
ro_object = lo_hmac.

" update HMAC with input
lo_hmac->update( if_data = input_string ).

" finalise hmac
lo_digest->final( ).

...


此程式碼能夠順利執行,但有程式碼存取權的任何人都可以存取 HMAC 金鑰。程式發佈後,除非修補此程式,否則可能無法變更硬式編碼的 HMAC 金鑰「secret_key」。若不懷好意的員工有此資訊的存取權,可能會使用此資訊來危害 HMAC 函數。

Abstract
硬式編碼的 HMAC 認證會導致無法輕易修正系統的安全性問題。
Explanation
切勿硬式編碼 HMAC 金鑰。HMAC 的加密強度取決於秘密金鑰的保密性,該秘密金鑰用於計算和驗證訊息驗證值。將 HMAC 金鑰硬式編碼,會讓擁有來源存取權的任何人都能檢視它,因此會減弱函數的加密強度。

範例 1:下列程式碼使用硬式編碼的金鑰來計算 HMAC:


import "crypto/hmac"
...
hmac.New(sha256.New, []byte("secret"))
...


此程式碼順利執行,但有程式碼存取權的任何人都可以存取 HMAC 金鑰。程式發佈後,除非修補此程式,否則絕無可能變更硬式編碼的 HMAC 金鑰「secret」。若不懷好意的員工有此資訊的存取權,可能會使用此資訊來危害 HMAC 函數。

Abstract
硬式編碼的 HMAC 金鑰可能會導致無法輕易修正的系統安全性問題。
Explanation
將 HMAC 金鑰硬式編碼絕對不是個好方法。HMAC 的加密強度取決於秘密金鑰的保密性,該秘密金鑰用於計算和驗證訊息驗證值。將 HMAC 金鑰硬式編碼,會讓擁有來源存取權的任何人都能檢視它,因此會減弱函數的加密強度。

範例 1:下列程式碼使用硬式編碼的金鑰來計算 HMAC:


...
CCHmac(kCCHmacAlgSHA256, "secret", 6, plaintext, plaintextLen, &output);
...


此程式碼能夠順利執行,但有程式碼存取權的任何人都可以存取 HMAC 金鑰。程式發佈後,除非修補此程式,否則可能無法變更硬式編碼的 HMAC 金鑰「secret」。若不懷好意的員工有此資訊的存取權,可能會使用此資訊來危害 HMAC 函數。

Abstract
硬式編碼的 HMAC 金鑰可能會導致無法輕易修正的系統安全性問題。
Explanation
將 HMAC 金鑰硬式編碼絕對不是個好方法。HMAC 的加密強度取決於秘密金鑰的保密性,該秘密金鑰用於計算和驗證訊息驗證值。將 HMAC 金鑰硬式編碼,會讓擁有來源存取權的任何人都能檢視它,因此會減弱函數的加密強度。

範例 1:下列程式碼使用硬式編碼的金鑰來計算 HMAC:


...
CCHmac(UInt32(kCCHmacAlgSHA256), "secret", 6, plaintext, plaintextLen, &output)
...


此程式碼能夠順利執行,但有程式碼存取權的任何人都可以存取 HMAC 金鑰。程式發佈後,除非修補此程式,否則可能無法變更硬式編碼的 HMAC 金鑰「secret」。若不懷好意的員工有此資訊的存取權,可能會使用此資訊來危害 HMAC 函數。

Abstract
硬式編碼密碼用於從密型金鑰衍生函數 (PBKDF) 產生金鑰。若將硬式編碼密碼提供給 PBKDF,可能會導致無法輕易修正的系統安全性問題。
Explanation
將空白值做為密碼引數傳遞給以密碼為基礎的金鑰衍生函數 (PBKDF) 絕對不是個好方法。在此情況下,衍生金鑰將完全以提供的 Salt 為基礎 (使其明顯安全性較低),且會極難修正問題。產生違反規則的程式碼以後,除非修補軟體,否則通常無法變更空白密碼。如果根據空白密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將硬式編碼值做為密碼引數傳遞到加密 PBKDF:


...
Rfc2898DeriveBytes rdb = new Rfc2898DeriveBytes("password", salt,100000);
...


不僅任何有程式碼存取權的人都能夠確定這會根據 Hardcoded Password 引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Hardcoded Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Hardcoded Password。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Hardcoded Password 的使用證據。

Abstract
根據硬式編碼密碼產生並使用加密金鑰時,會導致無法輕易修正的系統安全性問題。
Explanation
切勿將硬式編碼值做為密碼引數傳遞到以密碼為基礎的加密金鑰衍生函數 (PBKDF):在此情況下,產生的衍生金鑰大多將以提供的 Salt 為基礎 (使其安全性明顯降低),並且極難修正問題。產生違反規則的程式碼以後,除非修補軟體,否則通常無法變更硬式編碼的密碼。如果根據硬式編碼的密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將硬式編碼值做為密碼引數傳遞到加密 PBKDF:


const pbkdfPassword = "a secret";
crypto.pbkdf2(
pbkdfPassword,
salt,
numIterations,
keyLen,
hashAlg,
function (err, derivedKey) { ... }
)


不僅任何有程式碼存取權的人能夠確定這會根據硬式編碼密碼引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Hardcoded Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Hardcoded Password。若員工有此資訊的存取權,可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Hardcoded Password 的使用證據。

Abstract
硬式編碼密碼用於從密型金鑰衍生函數 (PBKDF) 產生金鑰。若將硬式編碼密碼提供給 PBKDF,可能會導致無法輕易修正的系統安全性問題。

Abstract
硬式編碼密碼用於從密型金鑰衍生函數 (PBKDF) 產生金鑰。若將硬式編碼密碼提供給 PBKDF,可能會導致無法輕易修正的系統安全性問題。
Explanation
切勿將硬式編碼值做為密碼引數傳遞到以密碼為基礎的加密金鑰衍生函數 (PBKDF):在此情況下,產生的衍生金鑰大多將以提供的 Salt 為基礎 (使其安全性明顯降低),並且極難修正問題。產生違反規則的程式碼以後,除非修補軟體,否則通常無法變更硬式編碼的密碼。如果根據硬式編碼的密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將硬式編碼值做為密碼引數傳遞到加密 PBKDF:


from hashlib import pbkdf2_hmac
...
dk = pbkdf2_hmac('sha256', 'password', salt, 100000)
...


不僅任何有程式碼存取權的人都能夠確定這會根據 Hardcoded Password 引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Hardcoded Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Hardcoded Password。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Hardcoded Password 的使用證據。

不僅任何有程式碼存取權的人都能夠確定這會根據 Hardcoded Password 引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 Hardcoded Password 產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則可能無法變更 Hardcoded Password。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 Hardcoded Password 的使用證據。

Abstract
Null 加密金鑰會導致無法輕易修正的安全性問題。
Explanation
使用 null 加密金鑰絕不是明智的想法,因為這不僅會明顯降低卓越加密演算法提供的保護,還會使修正問題變得極為困難。產生違反規則的程式碼以後,除非修補軟體,否則無法變更 null 加密金鑰。如果 null 加密金鑰保護的帳戶出現問題,系統的所有者將必須在安全性和可行性之間做出選擇。

範例 1:以下程式碼會使用 null 加密金鑰執行 AES 加密:


...
var encryptionKey:ByteArray = null;
...
var aes.ICipher = Crypto.getCipher("aes-cbc", encryptionKey, padding);
...


不僅是任何有程式碼存取權的人員可以判斷是否使用 null 加密金鑰,甚至是任何具有基本破解技術的人都很有可能成功解密任何加密的資料。應用程式發佈後,除非修補軟體,否則無法變更 null 加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 加密金鑰的使用證據。

Abstract
Null 加密金鑰會導致無法輕易修正的安全性問題。
Explanation
使用 null 加密金鑰絕不是明智的想法,因為這不僅會明顯降低卓越加密演算法提供的保護,還會使修正問題變得極為困難。產生違反規則的程式碼以後,除非修補軟體,否則無法變更 null 加密金鑰。如果 null 加密金鑰保護的帳戶出現問題,系統的所有者將必須在安全性和可行性之間做出選擇。

範例 1:以下程式碼會使用 null 加密金鑰執行 AES 加密:


...
SecretKeySpec key = null;
....
Cipher encryptCipher = Cipher.getInstance("AES");
encryptCipher.init(Cipher.ENCRYPT_MODE, key);
...


不僅是任何有程式碼存取權的人員可以判斷是否使用 null 加密金鑰,甚至是任何具有基本破解技術的人都很有可能成功解密任何加密的資料。應用程式發佈後,除非修補軟體,否則無法變更 null 加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 加密金鑰的使用證據。

Abstract
Null 加密金鑰會導致無法輕易修正的安全性問題。
Explanation
null 指定給加密金鑰變數是不當的做法,因為會讓敏感與加密資訊暴露給攻擊者。使用 null 加密金鑰不僅會明顯降低良好的加密演算法提供的保護,還會使修正問題變得極為困難。產生違反規則的程式碼以後,除非修補軟體,否則無法變更 null 加密金鑰。如果 null 加密金鑰保護的帳戶出現問題,系統的所有者將必須在安全性和可行性之間做出選擇。

範例 1:以下程式碼會將加密金鑰變數初始化為 null


...
$encryption_key = NULL;

$filter = new Zend_Filter_Encrypt($encryption_key);

$filter->setVector('myIV');

$encrypted = $filter->filter('text_to_be_encrypted');
print $encrypted;
...

擁有程式碼存取權的任何人均可以判斷是否使用 null 加密金鑰,且採用甚至是基本破解技術的任何人都很有可能成功解密任何加密的資料。程式發佈後,除非修補軟體,否則無法變更 null 加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 加密金鑰的使用證據。

Abstract
Null 加密金鑰會導致無法輕易修正的安全性問題。
Explanation
使用 null 加密金鑰絕對不是個好方法。使用 null 加密金鑰不僅會明顯降低良好的加密演算法提供的保護,還會使修正問題變得極為困難。產生違反規則的程式碼以後,除非修補軟體,否則無法變更 null 加密金鑰。如果 null 加密金鑰保護的帳戶出現問題,系統的所有者將必須在安全性和可行性之間做出選擇。

擁有程式碼存取權的任何人均可以判斷是否使用 null 加密金鑰,且採用甚至是基本破解技術的任何人都很有可能成功解密任何加密的資料。程式發佈後,除非修補軟體,否則無法變更 null 加密金鑰。若員工有此資訊的存取權,則可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 加密金鑰的使用證據。

Abstract
根據 null 密碼產生並使用加密金鑰時,可能會導致無法輕易修正系統安全性的問題。
Explanation
null 值做為密碼引數傳遞給以密碼為基礎的加密金鑰衍生函數絕對不是個好方法。在此情況下,產生的衍生金鑰將完全以提供的 Salt 為基礎 (使其明顯安全性較低),且會極難修正問題。違反規則的程式碼產生之後,除非修補軟體,否則通常無法變更 null 密碼。如果根據 null 密碼以衍生金鑰保護的帳戶出現問題,系統的所有者可能不得不在安全性和可用性之間選擇。

範例 1:以下程式碼將 null 值做為密碼引數傳遞到以密碼為基礎的加密金鑰衍生函數:


...
var encryptor = new StrongPasswordEncryptor();
var encryptedPassword = encryptor.encryptPassword(null);
...


不僅任何有程式碼存取權的人都能夠確定這會根據 null 密碼引數產生一或多個加密金鑰,甚至任何人運用基本破解技術,也都極可能會成功取得權限以存取由違反規則的金鑰所保護的任何資源。如果攻擊者還能存取用於根據 null 密碼產生任何金鑰的 Salt 值,則破解那些金鑰就變得相當簡單了。程式發佈後,除非修補此程式,否則不能變更 null 密碼。若員工有此資訊的存取權,可能會使用此資訊來進入並破壞系統。即使攻擊者僅有應用程式可執行檔的存取權,他們也可以擷取 null 密碼的使用證據。

Abstract
不應以純文字形式儲存密碼加密或簽署私密金鑰。
Explanation
用於加密或簽署的私密金鑰應視作敏感資料,在儲存之前應使用強式複雜密碼進行加密。這可防止在發生失竊或洩漏時兩種攻擊者以及權限不足的使用者未經授權存取資料。

範例 1:以下程式碼使用未加密的 PEM 格式匯出 RSA 私密金鑰:


from Crypto.PublicKey import RSA

key = RSA.generate(2048)
f = open('mykey.pem','w')
f.write(key.exportKey(format='PEM'))
f.close()

Abstract
某個 Kubernetes 元件洩漏系統資訊。
Explanation
如果啟用剖析,元件將透過 Web 介面提供效能指標。效能指標顯示的資訊有助於攻擊者建立攻擊計畫。不是啟動元件的指令中不存在 --profiling 旗標,就是該旗標設定為 true

Abstract
Kubelet 組態會阻止 Kubelet 設定 iptables。
Explanation
依預設,Kubelet 會根據 Pod 組態中的網路選項,自動對 iptables 進行必要變更。在 Kubelet 組態中,將 makeIPTablesUtilChains 設定為 enabled:false 可阻止 Kubelet 管理容器與環境其餘部分之間的網路流量。這會造成 Kubelet 無法強制執行必要的網路安全性需求,也無法設定容器所要求的連線。

範例 1:以下 Kubelet 組態會阻止 Kubelet 對 iptables 進行必要變更,這是因為設定了 makeIPTablesUtilChains: false

apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
makeIPTablesUtilChains: false

Abstract
Kubernetes API 伺服器中未啟用 AlwaysPullImages 准入控制器。
Explanation
從登錄中提取容器映像時,通常需要授權。然而,Kubernetes 節點會快取之前啟動的容器的所有映像。攻擊者可透過啟動具有快取映像的容器來規避必要的授權。AlwaysPullImages 准入控制器可以防止這種規避。

範例 1:以下組態將啟動一部 Kubernetes API 伺服器,而 --enable-admission-plugins 旗標中沒有 AlwaysPullImages 准入控制器。

Abstract
Kubernetes API 伺服器未設定使用任何准入控制器。
Explanation
准入控制器會驗證和自訂對 Kubernetes API 伺服器的要求。准入控制器可以實施安全性控制,例如拒絕未經授權的特權要求、強制命名空間隔離、限制過多的資源要求等等。API 伺服器不會驗證要求,因為沒有准入控制器或啟用了已棄用的 AlwaysAdmit 准入控制器。

Abstract
etcd 執行個體不會檢查所有傳入的 HTTPS 要求是否有信任憑證授權單位所簽署的用戶端憑證。
Explanation
Kubernetes 將敏感資料保存在 etcd 叢集中。etcd 執行個體接受來自用戶端的連線,而這些用戶端沒有由信任憑證授權單位簽署的憑證,因為啟動 etcd 的指令將 --client-cert-auth 旗標設定為 false

範例 1:以下組態將啟動一個 etcd 執行個體,並將 --client-cert-auth 旗標設定為 false

...
spec:
containers:
- command:
...
- etcd
...
--client-cert-auth=false

Abstract
已棄用的旗標將停用 Kubernetes API 伺服器與 Kubelet 之間的安全通訊。
Explanation
從 Kubernetes API 伺服器到 Kubelet 的連線,通常攜帶敏感資料,例如機密和指令。依預設,API 伺服器與 Kubelet 之間的連線會在傳輸過程中透過傳輸層安全性 (TLS) 進行保護。如果 --kubelet-https 旗標設定為 false,安全通訊將停用。

範例 1:以下組態將停用 API 伺服器與 Kubelet 之間的安全通訊,因為 API 伺服器是在 --kubelet-https 旗標設定為 false 的情況下啟動的。

containers:
- command:

Abstract
稽核記錄的保留期太短。
Explanation
記錄檔應保留足夠長的時間,以利進行事件後分析和威脅偵測,並滿足合規性要求。--audit-log-maxage 旗標定義保留舊稽核記錄檔的最大天數。不是啟動 Kubernetes API 伺服器的指令中不存在該旗標,就是設定的保留期少於 30 天。

範例 1:以下指令將啟動 Kubernetes API 伺服器,並將 --audit-log-maxage 旗標設定為 2 (即 2 天),這時間太短了。

Abstract
保留的稽核記錄數量不足。
Explanation
Kubernetes API 伺服器會自動輪換記錄檔。為利於進行事件後分析和威脅偵測,以及滿足合規性要求,您必須保留足夠的記錄資料量。--audit-log-maxbackup 旗標定義要保留的最大記錄檔數量。不是啟動 Kubernetes API 伺服器的指令中不存在此旗標,就是保留的最大記錄檔數量低於 10。

範例 1:以下指令將啟動 Kubernetes API 伺服器,並將 --audit-log-maxbackup 旗標設定為 2,這只會保留兩個記錄檔,顯然不夠。

Abstract
Kubelet 組態允許 Kubelet 覆寫核心預設值。
Explanation
如果 ProtectKernelDefaults 設定未設定或設定為 false,則 Kubelet 可以在執行階段期間修改核心參數。在部署 Kubernetes 之前,應該先最佳化並強化核心參數。若授予 Kubelet 變更核心參數的能力,將會擴大主機作業系統的受攻擊面。

範例 1:以下 Kubelet 組態允許 Kubelet 設定核心參數,這是因為有 ProtectKernelDefaults: false 設定。

apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
ProtectKernelDefaults: false
