Abstract
salt 值应使用加密伪随机数值生成器来创建。
Explanation
salt 值应使用加密伪随机数值生成器来创建。如果不使用随机 salt 值,则结果散列或 HMAC 的可预测性会高得多,也更容易受到字典式攻击。

示例 1:以下代码重新使用密码作为 salt:


...
byte[] passwd = Encoding.UTF8.GetBytes(txtPassword.Text);
Rfc2898DeriveBytes rfc = new Rfc2898DeriveBytes(passwd, passwd,10001);
...

Abstract
salt 值应使用加密伪随机数值生成器来创建。
Explanation
salt 值应使用加密伪随机数值生成器来创建。如果不使用随机 salt 值,则结果散列或 HMAC 的可预测性会高得多,也更容易受到字典式攻击。

例 1:以下代码重新使用密码作为 salt:


require 'openssl'
...
req = Rack::Response.new
password = req.params['password']
...
key = OpenSSL::PKCS5::pbkdf2_hmac(password, password, 100000, 256, 'SHA256')
...

Abstract
在加密散列中使用用户控制算法可能使攻击者能够指定弱加密散列算法,从而削弱应用程序的数据完整性与安全性。
Explanation
弱加密散列值:用户控制算法问题将在以下情况下出现:

1. 数据通过一个不可信赖的数据源进入程序

2. 用户控制的数据用于指定加密散列算法。

如同许多软件安全漏洞一样,弱加密散列值:用户控制算法只是通向终端的一个途径,它本身并不是终端。从本质上看,这些漏洞是显而易见的:攻击者可将恶意数据传递到应用程序,这些数据随后用于指定加密散列算法。攻击者可以指定一个存在已知缺陷的散列算法(比如 MD5),以破坏应用程序数据的完整性和安全性。

示例 1:以下代码使用了用户控制算法:

...
string hashname = ConfigurationManager.AppSettings["hash"];
...
HashAlgorithm ha = HashAlgorithm.Create(hashname);
...
Example 1 中的代码将成功运行,但任何有权使用此功能的人将能够通过修改 hash 属性来操纵散列算法。一旦程序发布,撤消与用户控制的算法相关的问题就会非常困难,因为很难知道恶意用户是否确定了特定加密散列的算法参数。

Abstract
在加密散列中使用用户控制算法可能使攻击者能够指定弱加密散列算法,从而削弱应用程序的数据完整性与安全性。
Explanation
在以下情况下会发生 Weak Cryptographic Hash:用户控制算法问题将在以下情况下出现:

1. 数据通过一个不可信赖的数据源进入程序

2. 用户控制的数据用于指定加密散列算法。

如同许多软件安全漏洞一样,Weak Cryptographic Hash:用户控制算法是到达终点的一个途径,其本身并不是终点。从本质上看,这些漏洞是显而易见的:攻击者可将恶意数据传递到应用程序,该数据随后用于指定加密散列算法。攻击者可以指定一个存在已知缺陷的散列算法(比如 MD5),以破坏应用程序数据的完整性和安全性。

例 1: 下列代码使用了用户控制算法:

require 'openssl'
require 'csv'
...
CSV.read(my_file).each do |row|
...
hash = row[4]
...
digest = OpenSSL::Digest.new(hash, data)
...
end
Example 1 中的代码将成功运行,但任何有权使用此功能的人将能够通过修改 CSV 文件中的 hash 来操纵散列算法。一旦程序发布,撤消与用户控制的算法相关的问题就会非常困难,因为很难知道恶意用户是否确定了特定加密散列的算法参数。

Abstract
一种生成加密散列的方法,从用户输入中传递一个最小位值。
Explanation
这可能使攻击者能够指定一个空的最小位,这样既可以更轻松地确定散列值,也可以泄露有关程序如何执行其加密散列的信息。在以下情况下会发生 Weak Cryptographic Hash: 用户控制的最小位问题将在以下情况下出现:

1.数据通过一个不可信赖的数据源进入程序。

2.用户控制的数据包括在最小位中,或完全用作加密散列函数中的最小位。


如同许多软件安全漏洞一样,Weak Cryptographic Hash: 用户控制的最小位是到达终点的一个途径,其本身并不是终点。从本质上看,这些漏洞是显而易见的:攻击者可将恶意数据传递到应用程序,然后这些数据被用作加密散列函数中的全部或部分最小位。

用户控制的最小位可以招致各种攻击:

1.攻击者可能会利用此漏洞为要散列的数据指定一个空的最小位。攻击者可以使用多种不同的散列算法快速对正在散列的数据进行散列,从而泄露有关应用程序中使用的散列实现的信息。这样,通过限制所用散列的特定变体,可以更轻松地“破解”其他数据值。
2.2.如果攻击者可以操纵其他用户的最小位,或者诱骗其他用户使用空的最小位,这使他们能够计算应用程序的“彩虹表”,并轻松地确定散列值。

示例 1:以下代码使用用户控制的最小位进行密码散列:

...
String minimumBits = prop.getProperty("minimumbits");
Hashing.goodFastHash(minimumBits).hashString("foo", StandardCharsets.UTF_8);
...
Example 1 中的代码将成功运行,但任何有权使用此功能的人都可以通过修改 minimumBits 属性来操纵用于对密码执行散列的最小位。一旦程序发布,撤消有关用户控制的最小位的问题就会非常困难,因为您无法知道密码散列的最小位是否由恶意用户设置。

Abstract
可能受污染的用户输入不应该作为 salt 参数传递到基于密码的密钥派生函数 (PBKDF)。
Explanation
弱加密散列值:用户控制 PBE Salt 问题将在以下情况下出现:

1. 数据通过一个不可信赖的数据源进入程序。

2. 用户控制的数据包括在 salt 中,或完全作为基于密码的密钥派生函数中的 salt 使用。


如同许多软件安全漏洞一样,弱加密散列值:用户控制 PBE Salt 只是通向终端的一个途径,它本身并不是终端。从本质上看,这些漏洞是显而易见的:攻击者可将恶意数据传递到应用程序,然后这些数据被用作 PBKDF 中的全部或部分 salt。

使用用户定义的 salt 的问题在于,它可以实现各种不同的攻击:

1. 攻击者可以利用这一漏洞,指定一个空 salt 作为自己的密码。由此,可以轻易地使用许多不同的散列快速地对其密码执行派生,以泄露有关您的应用程序中使用的 PBKDF 实现的信息。这样,通过限制所用散列的特定变体,可以更轻松地“破解”其他密码。
2. 如果攻击者能够操纵其他用户的 salt,或者诱骗其他用户使用空 salt,这将使他们能够计算应用程序的“彩虹表”,并更轻松地确定派生值。

示例 1:以下代码使用了用户控制 salt:

string salt = ConfigurationManager.AppSettings["salt"];
...

Abstract
可能受污染的用户输入不应该作为 salt 参数传递到基于密码的密钥派生函数 (PBKDF)。
Explanation
在以下情况下会发生 Weak Cryptographic Hash:用户控制 PBE 的 Salt 问题将在以下情况下出现:

1. 数据通过一个不可信赖的数据源进入程序

2. 用户控制的数据包括在 salt 中,或完全作为基于密码的密钥派生函数中的 salt 使用。


如同许多软件安全漏洞一样,Weak Cryptographic Hash:用户控制 PBE 的 Salt 是到达终点的一个途径,其本身并不是终点。从本质上看,这些漏洞是显而易见的:攻击者可将恶意数据传递到应用程序,然后这些数据被用作 PSKDF 中的全部或部分 salt。

用户控制 salt 的问题在于,它可以实现几个不同的攻击:

1. 攻击者可以利用这一漏洞,指定一个空 salt 作为自己的密码。由此,可以轻易地使用许多不同的散列快速地对其密码执行派生,以泄露有关您的应用程序中使用的 PBKDF 实现的信息。这样,通过限制所用散列的特定变体,可以更轻松地“破解”其他密码。
2. 如果攻击者能够操纵其他用户的 salt,或者诱骗其他用户使用空 salt,这将使他们能够计算应用程序的“彩虹表”,并更轻松地确定派生值。

例 1: 以下代码使用用户控制 salt:

...
salt = getenv("SALT");
PKCS5_PBKDF2_HMAC(pass, sizeof(pass), salt, sizeof(salt), ITERATION, EVP_sha512(), outputBytes, digest);
...
Example 1 中的代码将成功运行,但任何有权使用此功能的人将能够通过修改环境变量 SALT 来操纵用于派生密钥或密码的 salt。一旦程序发布,撤消与用户控制的 salt 相关的问题就会非常困难,因为很难知道恶意用户是否确定了密码散列的 salt。

Abstract
可能受污染的用户输入不应该作为 salt 参数传递到基于密码的密钥派生函数 (PBKDF)。
Explanation
弱加密散列值:用户控制 PBE Salt 问题将在以下情况下出现:

1. 数据通过一个不可信赖的数据源进入程序

2. 用户控制的数据包括在 salt 中,或完全作为基于密码的密钥派生函数中的 salt 使用。


如同许多软件安全漏洞一样,弱加密散列值:用户控制 PBE Salt 只是通向终端的一个途径,它本身并不是终端。从本质上看,这些漏洞是显而易见的:攻击者可将恶意数据传递到应用程序,然后这些数据被用作 PBKDF 中的全部或部分 salt。

使用用户定义的 salt 的问题在于,它可以实现各种不同的攻击:

1. 攻击者可以利用这一漏洞,指定一个空 salt 作为自己的密码。由此,可以轻易地使用许多不同的散列快速地对其密码执行派生,以泄露有关您的应用程序中使用的 PBKDF 实现的信息。这样,通过限制所用散列的特定变体,可以更轻松地“破解”其他密码。
2. 如果攻击者能够操纵其他用户的 salt,或者诱骗其他用户使用空 salt,这将使他们能够计算应用程序的“彩虹表”,并更轻松地确定派生值。

示例 1:以下代码会使用用户控制的 salt:

...
@property (strong, nonatomic) IBOutlet UITextField *inputTextField;
...
NSString *salt = _inputTextField.text;
const char *salt_cstr = [salt cStringUsingEncoding:NSUTF8StringEncoding];
...
CCKeyDerivationPBKDF(kCCPBKDF2,
password,
passwordLen,
salt_cstr,
salt.length,
kCCPRFHmacAlgSHA256,
100000,
derivedKey,
derivedKeyLen);
...
Example 1 中的代码将成功运行,但任何有权使用此功能的人将能够通过修改 UITextField inputTextField 中的文本来操纵用于派生密钥或密码的 salt。一旦程序发布,撤消与用户控制的 salt 相关的问题就会非常困难,因为很难知道恶意用户是否确定了密码散列的 salt。

Abstract
可能受污染的用户输入不应该作为 salt 参数传递到基于密码的密钥派生函数 (PBKDF)。
Explanation
在以下情况下会发生 Weak Cryptographic Hash:用户控制 PBE 的 Salt 问题将在以下情况下出现:

1. 数据通过一个不可信赖的数据源进入程序

2. 用户控制的数据包括在 salt 中,或完全作为基于密码的密钥派生函数中的 salt 使用。


如同许多软件安全漏洞一样,Weak Cryptographic Hash:用户控制 PBE 的 Salt 是到达终点的一个途径,其本身并不是终点。从本质上看,这些漏洞是显而易见的:攻击者可将恶意数据传递到应用程序,然后这些数据被用作 PSKDF 中的全部或部分 salt。

使用用户定义的 salt 的问题在于,它可以实现各种不同的攻击:

1. 攻击者可以利用这一漏洞,指定一个空 salt 作为自己的密码。由此,可以轻易地使用许多不同的散列快速地对其密码执行派生,以泄露有关您的应用程序中使用的 PBKDF 实现的信息。这样,通过限制所用散列的特定变体,可以更轻松地“破解”其他密码。
2. 如果攻击者能够操纵其他用户的 salt,或者诱骗其他用户使用空 salt,这将使他们能够计算应用程序的“彩虹表”,并更轻松地确定派生值。

例 1: 以下代码使用用户控制 salt:

...
salt=io.read
key = OpenSSL::PKCS5::pbkdf2_hmac(pass, salt, iter_count, 256, 'SHA256')
...
Example 1 中的代码将成功运行,但任何有权使用此功能的人将能够通过修改 salt 中的文本来操纵用于派生密钥或密码的 salt。一旦程序发布,撤消与用户控制的 salt 相关的问题就会非常困难,因为很难知道恶意用户是否确定了密码散列的 salt。

Abstract
可能受污染的用户输入不应该作为 salt 参数传递到基于密码的密钥派生函数 (PBKDF)。

弱加密散列值:用户控制 PBE Salt 问题将在以下情况下出现:

1. 数据通过一个不可信赖的数据源进入程序

2. 用户控制的数据包括在 salt 中,或完全作为基于密码的密钥派生函数中的 salt 使用。


如同许多软件安全漏洞一样,弱加密散列值:用户控制 PBE Salt 只是通向终端的一个途径,它本身并不是终端。从本质上看,这些漏洞是显而易见的:攻击者可将恶意数据传递到应用程序,然后这些数据被用作 PBKDF 中的全部或部分 salt。

desc.dataflow.cpp.weak_cryptographic_hash_user_controlled_salt
Abstract
不要接受生成加密散列的方法中的 salt 的用户输入。
Explanation
在以下情况下会发生 Weak Cryptographic Hash: 用户控制 salt 问题将在以下情况下出现:

1.数据通过一个不可信赖的数据源进入程序。

2.用户控制的数据包括在 salt 中,或完全用作加密散列函数中的 salt。


如同许多软件安全漏洞一样,Weak Cryptographic Hash: 用户控制 Salt 是到达终点的一个途径,其本身并不是终点。从本质上看,这些漏洞是显而易见的:攻击者可将恶意数据传递到应用程序,然后这些数据被用作加密散列函数中的全部或部分 salt。

用户定义的 salt 可以实现各种不同的攻击:

1.攻击者可以利用这一漏洞,指定一个空 salt 作为散列数据。然后攻击者可以使用许多不同的散列算法快速控制数据,以泄露有关您的应用程序中使用的散列实现的信息。这样,通过限制所用散列的特定变体,可以更轻松地“破解”其他数据值。
2.如果攻击者可以操纵其他用户的 salt,或者诱骗其他用户使用空 salt,这使他们能够计算应用程序的“彩虹表”,并轻松地确定散列值。

示例 1:以下代码使用用户控制 salt 进行密码散列:

func someHandler(w http.ResponseWriter, r *http.Request){
r.parseForm()
salt := r.FormValue("salt")
password := r.FormValue("password")
...
sha256.Sum256([]byte(salt + password))
}
Example 1 中的代码将成功运行,但任何有权使用此功能的人可以通过修改 salt 环境变量来操纵用于对密码执行散列的 salt。此外,此代码还会使用 Sum256 加密散列函数,而该函数不应该用于对密码执行加密散列。一旦程序发布,撤消与用户控制的 salt 相关的问题就会非常困难,因为很难知道恶意用户是否确定了密码散列的 salt。

Abstract
对于会生成作为 salt 传递的加密散列的方法,不应使用被污染的 salt 参数进行调用。
Explanation
在以下情况下会发生 Weak Cryptographic Hash:用户控制 salt 问题将在以下情况下出现:

1. 数据通过一个不可信赖的数据源进入程序。

2. 用户控制的数据包括在 salt 中,或完全用作加密散列函数中的 salt。

2. 如果攻击者能够操纵其他用户的 salt,或者诱骗其他用户使用空 salt,这将使他们能够计算应用程序的“彩虹表”,并更轻松地确定哈希值。

例 1: 以下代码使用用户控制 salt 进行密码散列:

Abstract
对于会生成作为 salt 传递的加密散列的方法,不应使用被污染的 salt 参数进行调用。
Explanation
在以下情况下会发生 Weak Cryptographic Hash:用户控制 salt 问题将在以下情况下出现:

1. 数据通过一个不可信赖的数据源进入程序

2. 用户控制的数据包括在 salt 中,或完全用作加密散列函数中的 salt。

如同许多软件安全漏洞一样,Weak Cryptographic Hash:用户控制 Salt 是到达终点的一个途径,其本身并不是终点。从本质上看,这些漏洞是显而易见的:攻击者可将恶意数据传递到应用程序,该数据随后用作加密散列中的 salt。

使用用户定义的 salt 的问题在于,它可以实现各种不同的攻击:

1. 攻击者可以利用这一漏洞,为被散列的数据指定一个空 salt。由此,可以轻易地使用许多不同的散列算法控制被散列的数据,以泄露有关您的应用程序中使用的散列实现的信息。这样,通过限制所用散列的特定变体,可以更轻松地“破解”其他密码。
2. 如果攻击者能够操纵其他用户的 salt,或者诱骗其他用户使用空 salt,这将使他们能够计算应用程序的“彩虹表”,并更轻松地确定哈希值。

例 1: 以下代码使用用户控制 salt 进行密码散列:

...
salt = req.params['salt']
hash = @userPassword.crypt(salt)
...
Example 1 中的代码将成功运行,但任何有权使用此功能的人将能够通过修改 salt 参数来操纵用于对密码执行散列的 salt。此外,此代码还使用了 String#crypt() 函数,该函数不应用于对密码执行加密散列。一旦程序发布,撤消与用户控制的 salt 相关的问题就会非常困难,因为很难知道恶意用户是否确定了密码散列的 salt。

Explanation
在以下情况下会发生 Weak Cryptographic Hash: 用户控制种子问题将在以下情况下出现:

1.数据通过一个不可信赖的数据源进入程序。

2.用户控制的数据包括在种子中,或完全用作加密散列函数中的种子。

用户控制的种子可以招致各种攻击:

1.攻击者可能会利用此漏洞为要散列的数据指定一个空种子。攻击者可以使用多种不同的散列算法快速对正在散列的数据进行散列,从而泄露有关应用程序中使用的散列实现的信息。这样,通过限制所用散列的特定变体,可以更轻松地“破解”其他数据值。
2.如果攻击者可以操纵其他用户的种子,或者诱骗其他用户使用空种子,这使他们能够计算应用程序的“彩虹表”,并轻松地确定散列值。

示例 1:以下代码使用用户控制的种子进行密码散列:

...

Abstract
不要使用过时的数字签名算法。
Explanation
数字签名是一种用于确定数字消息真实性和完整性的技术。数字签名算法 (DSA) 现已过时,不应再使用。与 RSA 等其他数字签名算法不同,DSA 存在固有缺陷。它需要每条消息的机密值 k,该值必须是加密随机、对外保密且绝不能重复使用的。如果攻击者可以猜出 k 值或者诱骗签名者使用其提供的值,则他们可以恢复私钥,然后伪造任何签名,从而冒充合法签名者。类似地,如果重复使用 k 值对多条消息进行签名,则攻击者可以恢复私钥。

Abstract
不要使用过时的数字签名算法。
Explanation
数字签名是一种用于确定数字消息真实性和完整性的技术。数字签名算法 (DSA) 现已过时,不应再使用。与 RSA 等其他数字签名算法不同,DSA 存在固有缺陷。它需要每条消息的机密值 k,该值必须是加密随机、对外保密且绝不能重复使用的。如果攻击者可以猜出 k 值或者诱骗签名者使用其提供的值,则他们可以恢复私钥,然后伪造任何签名,从而冒充合法签名者。类似地,如果重复使用 k 值对多条消息进行签名,则攻击者可以恢复私钥。

Abstract
原本强大的加密签名算法如果使用的密钥长度不够,就可能会更加容易受到强力攻击。
Explanation
当前的密码指南建议,RSA 和 DSA 算法使用的密钥长度至少应为 2048 位。但是,计算能力和因子分解技术方面的持续进步 [1] 意味着未来将不可避免地需要提高建议的密钥大小。

示例 1:以下代码生成 1024 位 DSA 签名密钥。

...
DSA dsa = new DSACryptoServiceProvider(1024);

Abstract
原本强大的加密签名算法如果使用的密钥长度不够,就会更加容易受到强力攻击。
Explanation
当前的密码指南建议,RSA 和 DSA 算法使用的密钥长度至少为 2048 位。但是,计算能力和因子分解技术方面的持续进步 [1] 意味着未来将不可避免地需要提高建议的密钥大小。

示例 1:以下代码可生成 1024 位 DSA 签名密钥。

...
dsa.GenerateParameters(params, rand.Reader, dsa.L1024N160)
privatekey := new(dsa.PrivateKey)
privatekey.PublicKey.Parameters = *params
dsa.GenerateKey(privatekey, rand.Reader)
...

Abstract
在生成加密签名过程中,代码错过了对一个必需步骤的调用。
Explanation
加密签名的生成涉及多个步骤,错过对任何必需步骤的调用都会削弱所生成签名的强度。

例 1: 以下代码跳过了对方法 EVP_SignUpdate 的调用,这将会导致创建不基于任何数据的签名:


...
rv = EVP_SignInit(ctx, EVP_sha512());
...
rv = EVP_SignFinal(ctx, sig, &sig_len, key);
...

Abstract
不应将受污染的密钥大小值传递给采用密钥大小参数的加密签名函数。
Explanation
允许用户控制的值来确定密钥大小会让攻击者可以指定一个空密钥,导致攻击者可以修改确保加密数据完整性的加密签名。即使要求使用非零值,攻击者也仍然可以指定尽可能低的密钥大小值,降低加密数据的完整性。

弱加密散列值:用户控制密钥大小问题将在以下情况下出现:

1. 数据通过一个不可信赖的数据源进入程序

2. 用户控制的数据被用作加密签名函数中密钥大小参数的全部或一部分

如同许多软件安全漏洞一样,弱加密散列值:用户控制密钥大小只是通向终端的一个途径,它本身并不是终端。从本质上看,这些漏洞是显而易见的:攻击者将恶意数据传送到应用程序,这些数据随后被用作执行加密的密钥大小值的全部或一部分。

当前的密码指南建议,RSA 和 DSA 算法使用的密钥长度至少应为 2048 位。但是,计算能力和因子分解技术方面的持续进步 [1] 意味着未来将不可避免地需要提高建议的密钥大小。即使将用户输入用作部分密钥大小,也可能会大大削弱签名的安全性,进而削弱加密数据的完整性。

示例 1:以下代码使用用户控制密钥大小参数生成 DSA 签名密钥:

...
DSA dsa1 = new DSACryptoServiceProvider(Convert.ToInt32(TextBox1.Text));
...


用户应该能够确定 key_len 的用例没有几个,即使在这些用例中,也应该有适当的保护来验证它不仅是一个数值而且还在密钥大小值的合理范围内。对于大多数用例,这应该是一个足够高的硬编码数字。

Abstract
采用密钥大小的加密签名函数可以接收受污染的密钥大小值。
Explanation
通过允许用户控制的值来确定密钥大小,攻击者可以指定一个空密钥,从而可以修改确保加密数据完整性的加密签名。即使要求使用非零值,攻击者也仍然可以指定尽可能低的密钥大小值,降低加密数据的完整性。

弱加密签名:用户控制密钥大小问题将在以下情况下出现:

1.数据通过一个不可信赖的数据源进入程序。

2.用户控制的数据被用作加密签名函数中密钥大小参数的全部或一部分。

如同许多软件安全漏洞一样,Weak Cryptographic Signature: 用户控制密钥大小是到达终点的一个途径,其本身并不是终点。从本质上看,这些漏洞是显而易见的:攻击者将恶意数据传送到应用程序,这些数据随后被用作用于执行加密的密钥大小值的全部或一部分。

当前的密码指南建议,RSA 和 DSA 算法使用的密钥长度至少为 2048 位。但是,计算能力和因子分解技术方面的持续进步 [1] 意味着未来将不可避免地需要提高建议的密钥大小。即使将用户输入用作部分密钥大小,也会削弱签名的安全性,进而削弱加密数据的完整性。

示例 1:下面的代码通过用户控制的密钥大小参数生成 DSA 签名密钥:

...
dsa.GenerateParameters(params, rand.Reader, key_len)
privatekey := new(dsa.PrivateKey)
privatekey.PublicKey.Parameters = *params
dsa.GenerateKey(privatekey, rand.Reader)
...


用户几乎不需要指定 key_len 的能力。在此类情况下,您应该验证它不仅是一个数值而且还处于密钥大小值的合理范围内。对于大多数用例,请选择一个足够大的硬编码密钥大小。

Abstract
不应将受污染的密钥大小值传递给采用密钥大小参数的加密签名函数。

例 1:下面的代码使用用户控制的密钥大小参数生成 DSA 签名密钥:

require 'openssl'
...
key_len = io.read.to_i

...


用户应该能够确定 key_len 的用例没有几个,即使在这些用例中,也应该有适当的保护来验证它不仅是一个数值而且还在密钥大小值的合理范围内。对于大多数用例,这应该是一个足够高的硬编码数字。

Abstract
代码禁用 XML 签名安全验证。
Explanation
XML 签名安全验证模式可以验证 XML 数字签名,并限制一些 XML 构造,以避免某些拒绝服务和其他类型的攻击。

这些限制包括:
- 禁止使用 XSLT 转换。
- 将 SignedInfo 或 Manifest Reference 元素的数量限制为 30 个或更少。
- 将引用转换的数量限制为 5 个或更少。
- 禁止使用 MD5 签名或 MD5 MAC 算法。
- 确保引用 ID 是唯一的,以帮助防止签名包装攻击。
- 禁止引用 http、https 或文件类型的 URI。
- 不允许 RetrievalMethod 元素引用另一个 RetrievalMethod 元素。
- 禁止小于 1024 位的 RSA 或 DSA 密钥。
- 禁止小于 224 位的 EC 密钥。

示例 1:以下代码使用系统属性禁用 XML 签名安全验证:

Properties props = System.getProperties();
...
properties.setProperty("org.jcp.xml.dsig.secureValidation", "false");
示例 2:以下代码使用 XMLCryptoContext.setProperty 禁用 XML 签名安全验证:

DOMCryptoContext cryptoContext = new DOMCryptoContext() {...};
...
cryptoContext.setProperty("org.jcp.xml.dsig.secureValidation", false);

识别调用会使用无法保证敏感数据的保密性的弱加密算法。
Explanation
过时的加密算法(如 DES)无法再为敏感数据的使用提供足够的保护。加密算法依赖于密钥大小,这是确保加密强度的主要方法之一。加密强度通常以生成有效密钥所需的时间和计算能力来衡量。计算能力的提高使得在合理的时间内获得较小的加密密钥成为可能。例如,在二十世纪七十年代首次开发出 DES 算法时,要破解在该算法中使用的 56 位密钥将面临巨大的计算障碍,但今天,使用常用设备能在不到一天的时间内破解 DES。

Abstract
标识调用会使用无法保证敏感数据的保密性的弱加密算法。
Explanation
过时的加密算法(如 DES)无法再为敏感数据的使用提供足够的保护。加密算法依赖于密钥大小,这是确保加密强度的主要方法之一。加密强度通常以生成有效密钥所需的时间和计算能力来衡量。计算能力的提高使得在合理的时间内获得较小的加密密钥成为可能。例如,在二十世纪七十年代首次开发出 DES 算法时,要破解在该算法中使用的 56 位密钥要克服巨大的计算障碍,但今天,攻击者借助常用设备就能在不到一天的时间内破解 DES。

Abstract
识别调用会使用无法保证敏感数据的保密性的弱加密算法。
Explanation
过时的加密算法,特别是使用不够长密钥的加密算法,不再能对含有敏感数据的使用提供充足的保护,随着技术的进步,在合理的时间内通过“强行破解”获得长度很短的加密密钥已经在计算上变为可行。例如,在二十世纪七十年代首次开发出该算法时,在 DES 中使用的 64 位密钥造成了巨大的计算障碍,但今天,使用常用设备能在不到一天的时间内破解 DES。

例 1:下列代码执行了算法不安全的加密 (DES):

...
CCCrypt(kCCEncrypt,
kCCAlgorithmDES,
kCCOptionPKCS7Padding,
key,
kCCKeySizeDES, // 64-bit key size
iv,
plaintext,
sizeof(plaintext),
ciphertext,
sizeof(ciphertext),
&numBytesEncrypted);
...

Abstract
识别调用会使用无法保证敏感数据的保密性的弱加密算法。
Explanation
过时的加密算法(如 DES)无法再为敏感数据的使用提供足够的保护。加密算法依赖于密钥大小,这是确保加密强度的主要方法之一。加密强度通常以生成有效密钥所需的时间和计算能力来衡量。计算能力的提高使得在合理的时间内获得较小的加密密钥成为可能。例如,在二十世纪七十年代首次开发出 DES 算法时,要破解在该算法中使用的 56 位密钥将面临巨大的计算障碍,但今天,使用常用设备能在不到一天的时间内破解 DES。

Abstract
识别调用会使用无法保证敏感数据的保密性的弱加密算法。
Explanation
过时的加密算法,特别是使用不够长密钥的加密算法,不再能对含有敏感数据的使用提供充足的保护,因为技术的进步使得在合理的时间内通过“强行破解”获得长度很短的加密密钥在计算上是可行的。例如,在二十世纪七十年代首次开发出 DES 算法时,要破解在该算法中使用的 64 位密钥将面临巨大的计算障碍,但今天,使用常用设备能在不到一天的时间内破解 DES。

示例 1:以下代码执行了算法不安全的加密 (DES):

...
let iv = getTrueRandomIV()
...
let cStatus = CCCrypt(UInt32(kCCEncrypt),
UInt32(kCCAlgorithmDES),
UInt32(kCCOptionPKCS7Padding),
key,
keyLength,
iv,
plaintext,
plaintextLength,
ciphertext,
ciphertextLength,
&numBytesEncrypted)
...

Abstract
识别调用会使用无法保证敏感数据的保密性的弱加密算法。
Explanation
过时的加密算法(如 DES)无法再为敏感数据的使用提供足够的保护。加密算法依赖于密钥大小,这是确保加密强度的主要方法之一。加密强度通常以生成有效密钥所需的时间和计算能力来衡量。计算能力的提高使得在合理的时间内获得较小的加密密钥成为可能。例如,在二十世纪七十年代首次开发出 DES 算法时,要破解在该算法中使用的 56 位密钥将面临巨大的计算障碍,但今天,使用常用设备能在不到一天的时间内破解 DES。

Abstract
将加密密钥转换为 String 会导致熵大量丢失。
Explanation
弱加密:字节数组至字符串转换问题将在以下情况下出现:

1. 加密密钥创建为字节数组


2. 将数据转换为 String示例 1:以下代码创建了加密密钥,然后将其转换为 String


import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
...
KeyGenerator keygen = KeyGenerator.newInstance("AES");
...
SecretKey cryptoKey = keygen.generateKey();
byte[] rawCryptoKey = cryptoKey.getEncoded();
...
String key = new String(rawCryptoKey);
...


这使用默认系统字符集将加密密钥转换为 String,但是对于为构造函数分配了字符集有效范围外的字节时将发生何种变化,却没有相关说明。事实上,与原始的 rawCryptoKey 加密密钥相比,key 很可能会造成熵的大量丢失。

Abstract
公钥 RSA 加密在不使用 OAEP 填充模式的情况下执行,因此加密机制比较脆弱。
Explanation
实际中,使用 RSA 公钥的加密通常与某种填充模式结合使用。填充模式可以防止一些针对 RSA 的攻击,这些攻击仅在不使用填充模式执行加密时才起作用。

示例 1:以下代码通过使用 PKCS#1 v1.5 填充模式的 RSA 公钥执行加密:

...
import "crypto/rsa"
...
plaintext := []byte("Attack at dawn")
cipherText, err := rsa.EncryptPKCS1v15(rand.Reader, &k.PublicKey, plaintext)
...

Abstract
公钥 RSA 加密在不使用 OAEP 填充模式的情况下执行,因此加密机制比较脆弱。
Explanation
实际中,使用 RSA 公钥的加密通常与某种填充模式结合使用。填充模式可以防止一些针对 RSA 的攻击,这些攻击仅在不使用填充模式执行加密时才起作用。

示例 1:以下代码在未使用填充模式的情况下执行 RSA 公钥加密:

...
from Crypto.PublicKey import RSA

message = 'Attack at dawn'
key = RSA.importKey(open('pubkey.der').read())
ciphertext = key.encrypt(message)
...

Abstract
应使用加密伪随机数生成器创建初始化矢量。
Explanation
应使用加密伪随机数生成器创建初始化矢量 (IV)。如果不使用随机 IV,生成的密码文本可预测性会更高,从而更容易受到 dictionary 攻击。

示例 1:以下代码使用非随机 IV 执行 AES 加密:


...
Blob iv = Blob.valueOf('1234567890123456');
Blob encrypted = Crypto.encrypt('AES128', encKey, iv, input);
...

Abstract
使用加密伪随机数生成器创建初始化矢量。
Explanation
使用加密伪随机数生成器创建初始化矢量 (IV)。否则,生成的密码文本可预测性会更高,也更容易受到 Dictionary 攻击。

示例 1:以下代码可重新使用密钥作为 IV:


import (
"crypto/aes"
"crypto/cipher"
"crypto/rand"
)
...
block, err := aes.NewCipher(key)
...
mode := cipher.NewCBCEncrypter(block, key)
mode.CryptBlocks(ciphertext[aes.BlockSize:], plaintext)


当使用密钥作为 IV 时,攻击者能够恢复密钥,从而能够解密数据。

Abstract
初始化矢量应该使用加密伪随机数值生成器进行创建。
Explanation
初始化矢量 (IV) 应该使用加密伪随机数值生成器进行创建。如果不使用随机 IV,则结果密码文本可预测性会高得多,容易受到字典式攻击。

示例 1:以下代码使用硬编码字节创建非随机 IV。


...
NSString *iv = @"1234567812345678"; //Bad idea to hard code IV
char ivPtr[kCCBlockSizeAES128];

[iv getCString:ivPtr maxLength:sizeof(ivPtr) encoding:NSASCIIStringEncoding];
...
ccStatus = CCCrypt( kCCEncrypt,
kCCAlgorithmAES128,
kCCOptionPKCS7Padding,
[key cStringUsingEncoding:NSASCIIStringEncoding],
kCCKeySizeAES128,
[ivPtr], /*IV should be something random (not null and not constant)*/
[self bytes], dataLength, /* input */
buffer, bufferSize, /* output */
&numBytesEncrypted
);


此外,如果在调用 CCCrypt 并且没有提供 IV (nil) 时选择了 CBC 模式,则将使用全零的 IV。

Abstract
初始化矢量应该使用加密伪随机数值生成器进行创建。
Explanation
初始化矢量 (IV) 应该使用加密伪随机数值生成器进行创建。如果不使用随机 IV,则结果密码文本可预测性会高得多,容易受到字典式攻击。

示例 1:以下代码重新使用密钥作为 IV:


from Crypto.Cipher import AES
from Crypto import Random
...
key = Random.new().read(AES.block_size)
cipher = AES.new(key, AES.MODE_CTR, IV=key)


当使用密钥作为 IV 时,攻击者可以恢复密钥,从而能够将数据解密。

Abstract
初始化矢量应该使用加密伪随机数值生成器进行创建。
Explanation
初始化矢量 (IV) 应该使用加密伪随机数值生成器进行创建。如果不使用随机 IV,则结果密码文本可预测性会高得多,容易受到字典式攻击。

示例 1:以下代码重新使用密钥作为 IV:


require 'openssl'
...
cipher = OpenSSL::Cipher::AES.new('256-GCM')
cipher.encrypt
@key = cipher.random_key
cipher.iv=@key

encrypted = cipher.update(data) + cipher.final # encrypts data without hardcoded IV
...


当使用密钥作为 IV 时,攻击者可以恢复密钥,从而能够将数据解密。

Abstract
初始化矢量应该使用加密伪随机数值生成器进行创建。
Explanation
初始化矢量 (IV) 应该使用加密伪随机数值生成器进行创建。如果不使用随机 IV,则结果密码文本可预测性会高得多,容易受到字典式攻击。

示例 1:以下代码使用硬编码字节创建非随机 IV。


...
let cStatus = CCCrypt(UInt32(kCCEncrypt),
UInt32(kCCAlgorithmAES128),
UInt32(kCCOptionPKCS7Padding),
key,
keyLength,
"0123456789012345",
plaintext,
plaintextLength,
ciphertext,
ciphertextLength,
&numBytesEncrypted)


此外,如果在调用 CCCrypt 并且没有提供 IV (nil) 时选择了 CBC 模式,则将使用全零的 IV。

Abstract
请勿将密码加密算法用于不安全的操作模式。
Explanation
块密码操作模式是一种算法,用来描述如何重复地应用密码的单块操作,以安全地转换大于块的数据量。一些操作模式包括电子代码本 (ECB)、密码块链 (CBC)、密码反馈 (CFB) 和计数器 (CTR)。

ECB 模式本质上较弱,因为它会对相同的明文块生成一样的密文。CBC 模式容易受到密文填塞攻击。CTR 模式由于没有这些缺陷,使之成为一个更好的选择。

示例 1:以下代码将 AES 密码用于 ECB 模式:


...
var objAesCryptoService = new AesCryptoServiceProvider();
objAesCryptoService.Mode = CipherMode.ECB;
objAesCryptoService.Padding = PaddingMode.PKCS7;
objAesCryptoService.Key = securityKeyArray;
var objCrytpoTransform = objAesCryptoService.CreateEncryptor();
...

Abstract

Explanation
块密码操作模式是一种算法,用来描述如何重复地应用密码的单块操作,以安全地转换大于块的数据量。一些操作模式包括电子代码本 (ECB)、密码块链 (CBC)、密码反馈 (CFB) 和计数器 (CTR)。

ECB 模式本质上较弱,因为它会对相同的明文块生成一样的密文。CBC 模式容易受到密文填塞攻击。CTR 模式由于没有这些缺陷,使之成为一个更好的选择。

示例 1:以下代码将 AES 密码用于 CBC 模式:

panic(err)
}

ciphertext := make([]byte, aes.BlockSize+len(plaintext))
iv := ciphertext[:aes.BlockSize]
if _, err := io.ReadFull(rand.Reader, iv); err != nil {
panic(err)

mode := cipher.NewCBCEncrypter(block, iv)
mode.CryptBlocks(ciphertext[aes.BlockSize:], plaintext)

Abstract
识别调用会使用无法保证敏感数据的保密性的弱加密算法。
Explanation
过时的加密算法(如 DES)无法再为敏感数据的使用提供足够的保护。加密算法依赖于密钥大小,这是确保加密强度的主要方法之一。加密强度通常以生成有效密钥所需的时间和计算能力来衡量。计算能力的提高使得在合理的时间内获得较小的加密密钥成为可能。例如,在二十世纪七十年代首次开发出 DES 算法时,要破解在该算法中使用的 56 位密钥将面临巨大的计算障碍,但今天,使用常用设备能在不到一天的时间内破解 DES。

Abstract
请勿将密码加密算法用于不安全的操作模式。
Explanation
块密码操作模式是一种算法,用来描述如何重复地应用密码的单块操作,以安全地转换大于块的数据量。一些操作模式包括电子代码本 (ECB)、密码块链 (CBC)、密码反馈 (CFB) 和计数器 (CTR)。

ECB 模式本质上较弱,因为它会对相同的明文块生成一样的密文。CBC 模式容易受到密文填塞攻击。CTR 模式由于没有这些缺陷,使之成为一个更好的选择。

示例 1:以下代码将 AES 密码用于 ECB 模式:


...

kCCAlgorithmAES,
kCCOptionECBMode, // Uses ECB mode
key,
kCCKeySizeAES128,
iv,

Abstract
请勿将密码加密算法用于不安全的操作模式。
Explanation
块密码操作模式是一种算法,用来描述如何重复地应用密码的单块操作,以安全地转换大于块的数据量。一些操作模式包括电子代码本 (ECB)、密码块链 (CBC)、密码反馈 (CFB) 和计数器 (CTR)。

ECB 模式本质上较弱,因为它会对相同的明文块生成一样的密文。CBC 模式容易受到密文填塞攻击。CTR 模式由于没有这些缺陷,使之成为一个更好的选择。

示例 1:以下代码将 AES 密码用于 ECB 模式:


from Crypto.Cipher import AES
from Crypto import Random
...
key = Random.new().read(AES.block_size)
random_iv = Random.new().read(AES.block_size)
cipher = AES.new(key, AES.MODE_ECB, random_iv)

Abstract
另外,当使用的密钥长度不够时,强大的加密算法便容易受到强力攻击。
Explanation
当前的密码指南建议,RSA 算法使用的密钥长度至少应为 2048 位。但是,计算能力和因子分解技术方面的持续进步 [1] 意味着未来将不可避免地需要提高建议的密钥大小。

示例 1:以下代码使用带有 512 位密钥的 RSA 算法。

static public byte[] EncryptWithRSA(byte[] plaintext, RSAParameters key) {
try {
RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(512);
rsa.ImportParameters(key);
return rsa.Encrypt(plaintext, true);
}
catch(CryptographicException e) {
Console.WriteLine(e.Message);
return null;
}
}


对于对称加密,密钥长度必须至少为 128 位。

Abstract
另外,当使用的密钥长度不够时,强大的加密算法便容易受到强力攻击。
Explanation
当前的密码指南建议,RSA 算法使用的密钥长度至少应为 2048 位。但是,计算能力和因子分解技术方面的持续进步 [1] 意味着未来将不可避免地需要提高建议的密钥大小。

例 1: 以下代码可生成 512 位 RSA 加密密钥。

EVP_PKEY * get_RSA_key() {
unsigned long err;
EVP_PKEY * pkey;
RSA * rsa;
rsa = RSA_generate_key(512, 35, NULL, NULL);
if (rsa == NULL) {
err = ERR_get_error();
printf("Error = %s\n",ERR_reason_error_string(err));
return NULL;
}
pkey = EVP_PKEY_new();
EVP_PKEY_assign_RSA(pkey, rsa);
return pkey;
}


对于对称加密,密钥长度必须至少为 128 位。

Abstract
另外,当使用的密钥长度不够时,强大的加密算法便容易受到强力攻击。
Explanation
当前的密码指南建议,RSA 算法使用的密钥长度至少应为 2048 位。但是,计算能力和因子分解技术方面的持续进步 [1] 意味着未来将不可避免地需要提高建议的密钥大小。

示例 1:以下代码可生成 512 位 RSA 密钥。

...
crmfObject = crypto.generateCRMFRequest(
"CN=" + name.value,
password.value,
authenticator,
keyTransportCert,
"setCRMFRequest();",
512, null, "rsa-dual-use");
...


对于对称加密,密钥长度必须至少为 128 位。

Abstract
另外,当使用的密钥长度不够时,强大的加密算法便容易受到强力攻击。
Explanation
当前的密码指南建议,RSA 算法使用的密钥长度至少应为 2048 位。但是,计算能力和因子分解技术方面的持续进步 [1] 意味着未来将不可避免地需要提高建议的密钥大小。

例 1: 以下代码可生成 1024 位 RSA 加密密钥。

require 'openssl'
...
pkey = OpenSSL::PKey::RSA.new 1024
...


对于对称加密,AES 的密钥长度必须至少为 128 位。

Abstract
在对称密钥生成、加密或解密过程中,代码错过了对一个必需步骤的调用。
Explanation
对称密钥的生成以及加密和解密涉及多个步骤,错过任何必需步骤都可能会削弱所生成对称密钥或密文的强度,或导致对现有密文的不正确解密。

例 1: 以下代码跳过了对 EVP_DecryptUpdate 的调用,这将导致密文解密失败。


...
EVP_DecryptInit_ex(&ctx, EVP_aes_256_gcm(), NULL, key, iv);
...
if(!EVP_DecryptFinal_ex(&ctx, outBuf+outBytes, &tmpOutBytes))
prtErrAndExit(1, "ERROR: EVP_DecryptFinal_ex did not work...\n");

Abstract
如果加密数据要存储在磁盘上,或者多次使用密钥,那么使用流密码就比较危险。
Explanation
流密码容易受到“密钥重新使用”攻击,又名“两次性密码本”攻击。当多次使用相同的密钥时,会产生这种类型的漏洞,因为可以轻易地对两个密码文本字符串进行异或运算并使密钥失效,从而只剩下异或后的明文。由于人类语言的格式化方式,通常可以轻松恢复两条原始消息。
为了阻止上述攻击,需要使用新的初始化向量 (IV),因此流密码不适合于存储加密数据,因为它意味着:
1) 磁盘扇区用作 IV:
由于在每次需要修改存储数据时都需要重新使用相同的 IV,因此这种方法并不安全。
2) 使用可将新的 IV 映射到磁盘扇区的复杂系统:
维护难度大。这种方法需要 IV 不断更新,需要使用户无法读取,需要密码文本占用的磁盘空间比未加密的明文更多。

基于上述两点,使用流密码而不是块密码来存储加密数据十分不利。流密码的另一个问题是,它们不会提供身份验证,因此容易受到“位翻转”攻击。一些块密码(例如“CTR”)同样容易受到这些攻击,因为它们与流密码的工作原理相似。

示例 1:以下代码可创建流密码,然后将其与常量 IV 一起用于加密数据,再存储到磁盘上:


import (
"crypto/aes"
"crypto/cipher"
"os"
)
...
iv = b'1234567890123456'
CTRstream = cipher.NewCTR(block, iv)
CTRstream.XORKeyStream(plaintext, ciphertext)
...
f := os.Create("data.enc")
f.Write(ciphertext)
f.Close()


Example 1 中,由于 iv 设置为常量初始化向量,因此容易受到重用攻击。

Abstract
当与存储的数据结合使用时,或者该密钥使用了不止一次时,流密码会很危险。
Explanation
流密码容易受到“密钥重新使用”攻击,又称“两次性密码本”攻击。这意味着,如果多次使用相同的密钥,则可以对密码文本的两个字符串进行异或运算并使密钥失效,从而只剩下异或后的明文。由于人类语言的格式化方式,通常可以轻松恢复两条原始消息。
为了阻止上述攻击,需要使用一个新的初始化矢量 (IV),因此流密码不适用于存储加密数据,正如它意味着:
1) 使用磁盘扇区作为 IV:
由于在每次需要修改存储数据时都必须重新使用相同的 IV,因此这种方法并不安全。
2) 具有可将新的 IV 映射到磁盘扇区的复杂系统:
由于需要不断更新,必须禁止用户可读,且密码文本需要占用的磁盘空间也比单独的未加密明文更多,因此这种方法不容易维护。

基于上述两点,使用流密码而不是块密码来存储加密数据十分不利。流密码的另一个问题是,它们不会提供身份验证,因此容易受到“位翻转”攻击。一些块密码(例如“CTR”)同样容易受到这些攻击,因为它们与流密码的工作原理相似。

示例 1:以下代码可创建流密码,然后将其与常量 IV 一起用于加密数据,再存储到磁盘上:


...
const cipher = crypto.createCipheriv("AES-256-CTR", key, 'iv')
const ciphertext = cipher.update(plaintext, 'utf8');
cipher.final();
fs.writeFile('my_encrypted_data', ciphertext, function (err) {
...
});

iv = b'1234567890123456'
cipher = AES.new(key, AES.MODE_CTR, iv, counter)
...
encrypted = cipher.encrypt(data)
f = open("data.enc", "wb")
f.write(encrypted)
f.close()
...


Example 1 中,由于 iv 设置为常量初始化向量,因此容易受到重用攻击。
