Abstract
采用普通的编码方式给密码加密并不能有效地保护密码。
Explanation
当密码以明文形式存储在应用程序的属性文件或其他配置文件中时,会发生 password management 漏洞。程序员试图通过编码函数来遮蔽密码,以修补 password management 漏洞,例如使用 64 位基址编码方式,但都不能起到充分保护密码的作用。
示例:以下代码可以从属性文件中读取密码,并使用该密码为 URL 请求设置默认 authentication 凭证。


...
var fs:FileStream = new FileStream();
fs.open(new File("config.properties"), FileMode.READ);
var decoder:Base64Decoder = new Base64Decoder();
decoder.decode(fs.readMultiByte(fs.bytesAvailable, File.systemCharset));
var password:String = decoder.toByteArray().toString();

URLRequestDefaults.setLoginCredentialsForHost(hostname, usr, password);
...


该代码可以正常运行,但是任何对 config.properties具有访问权限的人都能读取 password 的值,并且很容易确定这个值是否经过 64 位基址编码。任何心怀不轨的雇员可以利用手中掌握的信息访问权限入侵系统。

Abstract
采用普通的编码方式使密码模糊化无法保护密码。
Explanation
当密码以明文形式存储在应用程序的属性或配置文件中时,会发生 password management 问题。程序员试图通过编码函数使密码模糊化,以解决 password management 问题,例如使用 64 位基址编码方式,但都无法起到充分保护密码的作用。
示例:以下代码可以从 JSON 文件中读取密码,并使用该密码来设置请求的授权标头。


...
file, _ := os.Open("config.json")
decoder := json.NewDecoder(file)
decoder.Decode(&values)
password := base64.StdEncoding.DecodeString(values.Password)

request.SetBasicAuth(values.Username, password)
...


该代码可以正常运行,但是任何对 config.json 具有访问权限的人都能读取 password 的值,并且很容易确定这个值是否经过 64 位基址编码。任何心怀不轨的雇员可以利用手中掌握的信息访问权限入侵系统。

Abstract
采用普通的编码方式给密码加密并不能有效地保护密码。
Explanation
当密码以明文形式存储在应用程序的属性文件或其他配置文件中时,会发生 password management 漏洞。程序员试图通过编码函数来遮蔽密码,以修补 password management 漏洞,例如使用 64 位基址编码方式,但都不能起到充分保护密码的作用。
例 1:以下代码可以从属性文件中读取密码,并使用该密码连接到数据库。


...
Properties prop = new Properties();
prop.load(new FileInputStream("config.properties"));
String password = Base64.decode(prop.getProperty("password"));

DriverManager.getConnection(url, usr, password);
...


该代码可以正常运行,但是任何对 config.properties具有访问权限的人都能读取 password 的值,并且很容易确定这个值是否经过 64 位基址编码。任何心怀不轨的雇员可以利用手中掌握的信息访问权限入侵系统。

在移动环境中,由于设备丢失的几率较高,所以 password management 非常重要。
示例 2:以下代码会从 Android WebView 存储中读取用户名和密码,并使用它们设置用于查看受保护页面的身份验证。

...
webview.setWebViewClient(new WebViewClient() {
public void onReceivedHttpAuthRequest(WebView view,
HttpAuthHandler handler, String host, String realm) {
String[] credentials = view.getHttpAuthUsernamePassword(host, realm);
String username = new String(Base64.decode(credentials[0], DEFAULT));
String password = new String(Base64.decode(credentials[1], DEFAULT));
handler.proceed(username, password);
}
});
...


默认情况下,WebView 凭证以明文的形式存储且不经过 hash 处理。因此,如果用户拥有 root 设备(或使用仿真器),他/她就能读取存储的给定站点的密码。

Abstract
采用普通的编码方式给密码加密并不能有效地保护密码。
Explanation
当密码以明文形式存储在应用程序的属性文件或其他配置文件中时,会发生 password management 漏洞。 程序员试图通过编码函数来遮蔽密码,以修补 password management 漏洞,例如使用 64 位基址编码方式,但都不能起到充分保护密码的作用。
示例:下面的代码会从 plist 文件读取密码,然后使用该密码解压缩受密码保护的文件。

...
NSDictionary *dict= [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Config" ofType:@"plist"]];
NSString *encoded_password = [dict valueForKey:@"encoded_password"];
NSData *decodedData = [[NSData alloc] initWithBase64EncodedString:encoded_password options:0];
NSString *decodedString = [[NSString alloc] initWithData:decodedData encoding:NSUTF8StringEncoding];
[SSZipArchive unzipFileAtPath:zipPath toDestination:destPath overwrite:TRUE password:decodedString error:&error];
...


这组代码可以顺利运行,但是任何对 Config.plist 文件具有访问权限的人都能读取 encoded_password 的值,并且很容易确定这个值是否经过 64 位基址编码。

在移动环境中,由于设备丢失的几率较高,所以 password management 非常重要。

desc.dataflow.python.password_management_weak_cryptography
Abstract
采用普通的编码方式给密码加密并不能有效地保护密码。
Explanation
当密码以明文形式存储在应用程序的配置文件或其他数据存储中时,会发生 password management 漏洞。程序员试图通过编码函数来遮蔽密码,以修补 password management 漏洞,例如使用 64 位基址编码方式,但都不能起到充分保护密码的作用。
示例:以下代码会从环境变量中读取密码,使用一种简单的编码算法将密码解码,然后使用该密码连接至数据库。


require 'pg'
require 'base64'
...
passwd = Base64.decode64(ENV['PASSWD64'])
...
conn = PG::Connection.new(:dbname => "myApp_production", :user => username, :password => passwd, :sslmode => 'require')



该代码可以正常运行,但是任何对用于存储密码的环境变量具有访问权限的人都能读取 PASSWD64的值,并且很容易确定这个值是否经过 64 位基址编码。任何心怀不轨的雇员可以利用手中掌握的信息访问权限入侵系统。

示例 1:下面的代码会从 plist 文件读取密码,然后使用该密码解压缩受密码保护的文件。

...
var myDict: NSDictionary?
if let path = NSBundle.mainBundle().pathForResource("Config", ofType: "plist") {
myDict = NSDictionary(contentsOfFile: path)
}
if let dict = myDict {
let password = base64decode(dict["encoded_password"])
zipArchive.unzipOpenFile(zipPath, password:password])
}
...


这组代码可以顺利运行,但是任何对 Config.plist 文件具有访问权限的人都能读取 encoded_password 的值,并且很容易确定这个值是否经过 64 位基址编码。

在移动环境中,由于设备丢失的几率较高,所以 password management 非常重要。

Abstract
采用普通的编码方式使密码模糊化无法保护密码。
Explanation
当密码以明文形式存储在应用程序的属性或配置文件中时,会发生 password management 问题。程序员试图通过编码函数使密码模糊化,以解决 password management 问题,例如使用 64 位基址编码方式,但都无法起到充分保护密码的作用。

示例 1:以下 Linux 影子文件包含使用弱加密算法 DES 的密码。


...
root:qFio7llfVKk.s:19033:0:99999:7:::
...


DES 算法已被证实很弱,且可以在几天内被强力破解。

Abstract
采用普通的编码方式给密码加密并不能有效地保护密码。
Explanation
当密码以明文形式存储在应用程序的属性文件或其他配置文件中时,会发生 password management 漏洞。程序员试图通过编码函数来遮蔽密码,以修补 password management 漏洞,例如使用 64 位基址编码方式,但都不能起到充分保护密码的作用。
示例:以下代码可以从属性文件中读取密码,并使用该密码连接到数据库。


...
...
Private Declare Function GetPrivateProfileString _
Lib "kernel32" Alias "GetPrivateProfileStringA" _
(ByVal lpApplicationName As String, _
ByVal lpKeyName As Any, ByVal lpDefault As String, _
ByVal lpReturnedString As String, ByVal nSize As Long, _
ByVal lpFileName As String) As Long
...
Dim password As String
...
password = StrConv(DecodeBase64(GetPrivateProfileString("MyApp", "Password", _
"", value, Len(value), _
App.Path & "\" & "Config.ini")), vbUnicode)
...
con.ConnectionString = "Driver={Microsoft ODBC for Oracle};Server=OracleServer.world;Uid=scott;Passwd=" & password &";"
...



该代码可以正常运行,但是任何对 Config.ini具有访问权限的人都能读取 Password 的值,并且很容易确定这个值是否经过 64 位基址编码。任何心怀不轨的雇员可以利用手中掌握的信息访问权限入侵系统。

desc.dataflow.vb.password_management_weak_cryptography
Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到了一个外部介质,例如控制台、file system 或网络。
示例 1:以下代码包含一个日志记录语句,该语句通过在日志文件中存储添加到数据库中的各条记录信息来跟踪这些信息。


pass = getPassword();
...
dbmsLog.println(id+":"+pass+":"+type+":"+tstamp);
Example 1 中的代码会将明文密码记录到文件系统中。虽然许多开发人员认为文件系统是存储数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

在移动世界中隐私是最令人担心的问题之一,其原因有以下两点。一是设备丢失的几率较高。第二点与移动应用程序之间的进程间通信有关。在移动平台上,可以从各种来源下载应用程序,并且可以在同一设备上同时运行这些应用程序。因为恶意软件在银行应用程序附近运行的可能性很高,所以应用程序的作者需要注意消息所包含的信息,这些消息将会发送给在设备上运行的其他应用程序。移动应用程序之间的进程间通信不应包含敏感信息。

示例 2:以下代码会从 Android WebView 存储中读取给定站点的用户名和密码,并将其广播给所有注册的接收者。

...
webview.setWebViewClient(new WebViewClient() {
public void onReceivedHttpAuthRequest(WebView view,
HttpAuthHandler handler, String host, String realm) {
String[] credentials = view.getHttpAuthUsernamePassword(host, realm);
String username = credentials[0];
String password = credentials[1];
Intent i = new Intent();
i.setAction("SEND_CREDENTIALS");
i.putExtra("username", username);
i.putExtra("password", password);
view.getContext().sendBroadcast(i);
}
});
...


此示例演示了几个问题。首先,WebView 凭证以明文的形式存储且不经过 hash 处理。因此,如果用户拥有 root 设备(或使用仿真器),他们就能读取存储的给定站点的密码。其次,明文凭证将被广播给所有注册的接收者,这就意味着任何使用 SEND_CREDENTIALS 收听的注册接收者都将收到消息。即使权限限制接收者人数,广播也不会受到保护;既然这样,我们也不建议将权限作为修复方式使用。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取

— 由应用程序访问数据库或者其他数据存储形式

— 间接地从合作者或者第三方处获取

通常,在移动环境下,此私人信息除了包括密码、SSN 和其他常规个人信息之外,还包括以下信息:

- 位置

- 手机号码

- 序列号和设备 ID

- 网络运营商信息

- 语音信箱信息


有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
允许用户输入以直接更改权限可能导致攻击者能够访问以其他方式保护的系统资源。
Explanation
如果攻击者能够修改应用程序中用于确定权限的值,则会出现权限操纵错误。

示例 1:以下代码使用来自文件的输入确定应用程序中所需的 FileIOPermissions


...
String permissionsXml = GetPermissionsFromXmlFile();
FileIOPermission perm = new FileIOPermission(PermissionState.None);
perm.FromXml(permissionsXml);
perm.Demand();
...


在这种情况下,如果用户能够控制用于检索数据的 XML 文件,则他们可控制系统可能要求的权限。

Abstract
允许用户输入直接更改权限以确定审核是否可能使攻击者能够隐藏他们的活动。
Explanation
如果攻击者能够修改应用程序中用于确定权限(用于确定记录内容)的值,则会出现权限操纵记录错误。Windows 中存在系统访问控制列表 (SACL),用于确定应该审核的用户和组以对照资源查看访问是成功还是失败。如果攻击者可以控制存储在这些设置或访问设置中的访问控制项 (ACE),则攻击者有可能会禁止审核其帐户,这样就更难确定攻击者可能产生哪些破坏。

示例 1:以下代码允许用户指定生成审核日志的操作。


...
CrytoKeyAuditRule auditRule = new CryptoKeyAuditRule(IdRef, (CryptoKeyRights) input, AuditFlags.Success);
...


在这种情况下,如果用户可以控制 input,则他们可以指定能够记录的操作类型。如果用户可以将此操纵到 CryptoKeyRights.Delete,则他们也许能够读取加密密钥而不记录它,这样您不会意识到攻击者已盗取您的加密密钥。

Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到外部位置,如控制台、file system 或网络。
示例:以下代码以明文形式向屏幕发送 FTP 帐户凭证。

...
uid = 'scott'.
password = 'tiger'.
WRITE: / 'Default username for FTP connection is: ', uid.
WRITE: / 'Default password for FTP connection is: ', password.
...


其他例子中可能也会存在这样的情况,即,将明文密码通过日志记录语句存储到文件系统中。虽然许多开发人员认为文件系统是存储数据的安全位置,但这不是绝对的,特别是在涉及到隐私问题时。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取

— 由应用程序访问数据库或者其他数据存储形式

— 间接地从合作者或者第三方处获取

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

desc.dataflow.abap.privacy_violation
Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到了一个外部介质,例如控制台、file system 或网络。
示例 1:以下代码包含一个日志记录语句,该语句通过在日志文件中存储添加到数据库中的各条记录信息来跟踪这些信息。


pass = getPassword();
...
trace(id+":"+pass+":"+type+":"+tstamp);
Example 1 中的代码会将明文密码记录到文件系统中。虽然许多开发人员认为文件系统是存储数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取

— 由应用程序访问数据库或者其他数据存储形式

— 间接地从合作者或者第三方处获取

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
将未屏蔽的私人用户数据(如客户密码或社会保障号码)发送到外部位置会损害用户隐私,这通常是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1.检索私人用户信息。

2.数据被写到外部位置,如控制台、文件系统或网络。
示例 1:以下代码包含一个日志记录语句,该语句将新设置的密码打印到调试日志中。

desc.dataflow.apex.privacy_violation
Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到外部位置,如控制台、file system 或网络。
示例 1:以下代码包含一个日志记录语句,该语句通过在日志文件中存储添加到数据库中的各条记录信息来跟踪这些信息。


pass = GetPassword();
...
dbmsLog.WriteLine(id+":"+pass+":"+type+":"+tstamp);
Example 1 中的代码会将明文密码记录到文件系统中。虽然许多开发人员认为文件系统是存储数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取

— 由应用程序访问数据库或者其他数据存储形式

— 间接地从合作者或者第三方处获取

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

desc.dataflow.cpp.privacy_violation
Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到外部位置,如控制台、file system 或网络。
示例:以下代码以明文形式向终端发送数据库帐户凭证。

...
MOVE "scott" TO UID.
MOVE "tiger" TO PASSWORD.
DISPLAY "Default username for database connection is: ", UID.
DISPLAY "Default password for database connection is: ", PASSWORD.
...


其他例子中可能也会存在这样的情况,即,将明文密码通过日志记录语句存储到文件系统中。虽然许多开发人员认为文件系统是存储数据的安全位置,但这不是绝对的,特别是在涉及到隐私问题时。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取

— 由应用程序访问数据库或者其他数据存储形式

— 间接地从合作者或者第三方处获取

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
对私人信息(如客户密码或社会保障号码)处理不当会损害用户隐私,这通常是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1.用户私人信息进入了程序。

2.数据被写到外部位置,如控制台、文件系统或网络。
示例 1:以下代码包含一个日志记录语句,该语句通过在日志文件中存储添加到数据库中的各条记录信息来跟踪这些信息。


var pass = getPassword();
...
dbmsLog.println(id+":"+pass+":"+type+":"+tstamp);
Example 1 中的代码会将明文密码记录到文件系统中。虽然许多开发人员认为文件系统是存储数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

在移动世界中隐私是最令人担心的问题之一,其原因有以下两点。一是设备丢失的几率较高。第二点与移动应用程序之间的进程间通信有关。在移动平台上,可以从各种来源下载应用程序,并且可以在同一设备上同时运行这些应用程序。因为恶意软件在银行应用程序附近运行的可能性很高,所以应用程序的作者需要注意消息所包含的信息,这些消息将会发送给在设备上运行的其他应用程序。请勿在移动应用程序之间的进程间通信中包含敏感信息。

可以通过多种方式将私人数据输入到程序中:

- 以密码或个人信息的形式直接从用户处获取

- 由应用程序访问数据库或者其他数据存储器

- 从合作伙伴或其他第三方间接获取

通常,在移动环境下,此私人信息除了包括密码、SSN 和其他常规个人信息之外,还包括以下信息:

- 位置

- 手机号码

- 序列号和设备 ID

- 网络运营商信息

- 语音信箱信息


有时,未贴上私人标签的数据在其他上下文中也有可能成为私人信息。例如,学生的学号通常不视为私人信息,因为学号中并没有明确且公开可用的信息来反映学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然不安全地处理私人数据有多种形式,但是常见的风险来自于盲目的信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

为能够妥善应对此类备受瞩目的信息盗取事件,私人数据的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

这些规范业已存在,但侵犯隐私的情况仍时有发生。

[64] Standards Mapping - Web Application Security Consortium Version 2.00 Information Leakage (WASC-13)
[65] Standards Mapping - Web Application Security Consortium 24 + 2 Information Leakage
desc.dataflow.golang.privacy_violation
Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到了一个外部介质,例如控制台、file system 或网络。
示例 1:以下代码包含一个日志记录语句,该语句通过在日志文件中存储添加到数据库中的各条记录信息来跟踪这些信息。


pass = getPassword();
...
dbmsLog.println(id+":"+pass+":"+type+":"+tstamp);
Example 1 中的代码会将明文密码记录到文件系统中。虽然许多开发人员认为文件系统是存储数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

在移动世界中隐私是最令人担心的问题之一,其原因有以下两点。一是设备丢失的几率较高。第二点与移动应用程序之间的进程间通信有关。在移动平台上,可以从各种来源下载应用程序,并且可以在同一设备上同时运行这些应用程序。因为恶意软件在银行应用程序附近运行的可能性很高,所以应用程序的作者需要注意消息所包含的信息,这些消息将会发送给在设备上运行的其他应用程序。移动应用程序之间的进程间通信不应包含敏感信息。

示例 2:以下代码会从 Android WebView 存储中读取给定站点的用户名和密码,并将其广播给所有注册的接收者。

...
webview.setWebViewClient(new WebViewClient() {
public void onReceivedHttpAuthRequest(WebView view,
HttpAuthHandler handler, String host, String realm) {
String[] credentials = view.getHttpAuthUsernamePassword(host, realm);
String username = credentials[0];
String password = credentials[1];
Intent i = new Intent();
i.setAction("SEND_CREDENTIALS");
i.putExtra("username", username);
i.putExtra("password", password);
view.getContext().sendBroadcast(i);
}
});
...


此示例演示了几个问题。首先,WebView 凭证以明文的形式存储且不经过 hash 处理。因此,如果用户拥有 root 设备(或使用仿真器),他们就能读取存储的给定站点的密码。其次,明文凭证将被广播给所有注册的接收者,这就意味着任何使用 SEND_CREDENTIALS 收听的注册接收者都将收到消息。即使权限限制接收者人数,广播也不会受到保护;既然这样,我们也不建议将权限作为修复方式使用。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取

— 由应用程序访问数据库或者其他数据存储形式

— 间接地从合作者或者第三方处获取

通常,在移动环境下,此私人信息除了包括密码、SSN 和其他常规个人信息之外,还包括以下信息:

- 位置

- 手机号码

- 序列号和设备 ID

- 网络运营商信息

- 语音信箱信息


有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

[65] Standards Mapping - Web Application Security Consortium 24 + 2 Information Leakage
desc.dataflow.javascript.privacy_violation
Abstract
对私人信息(如客户密码或社会保障号码)处理不当会损害用户隐私,这通常是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1.用户私人信息进入了程序。

2.数据被写到外部位置,如控制台、文件系统或网络。
示例 1:以下代码包含一个日志记录语句,该语句通过在日志文件中存储添加到数据库中的各条记录信息来跟踪这些信息。


pass = getPassword()
...
dbmsLog.println("$id:$pass:$type:$tstamp")
Example 1 中的代码会将明文密码记录到文件系统中。虽然许多开发人员认为文件系统是存储数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

在移动环境中隐私是最令人担心的问题之一,其原因有以下两点。一是设备丢失的几率较高。第二点与移动应用程序之间的进程间通信有关。在移动平台上,可以从各种来源下载应用程序,并且可以在同一设备上同时运行这些应用程序。因为恶意软件在银行应用程序附近运行的可能性很高,所以开发人员必须注意消息所包含的信息,这些消息将会发送给在设备上运行的其他应用程序。请勿在移动应用程序之间的进程间通信中包含敏感信息。

示例 2:以下代码会从 Android WebView 存储中读取给定站点的用户名和密码,并将其广播给所有注册的接收者。

...
webview.webViewClient = object : WebViewClient() {
override fun onReceivedHttpAuthRequest(view: WebView,
handler: HttpAuthHandler, host: String, realm: String
) {
val credentials = view.getHttpAuthUsernamePassword(host, realm)
val username = credentials!![0]
val password = credentials[1]
val i = Intent()
i.action = "SEND_CREDENTIALS"
i.putExtra("username", username)
i.putExtra("password", password)
view.context.sendBroadcast(i)
}
}
...


此示例演示了几个问题。首先,WebView 凭证以明文的形式存储且不经过 hash 处理。因此,如果用户拥有 root 设备(或使用仿真器),他们就能读取存储的给定站点的密码。其次,明文凭证将被广播给所有注册的接收者,这就意味着任何使用 SEND_CREDENTIALS 收听的注册接收者都将收到消息。即使权限限制接收者人数,广播也不会受到保护;既然这样,我们也不建议将权限作为修复方式使用。

可以通过多种方式将私人数据输入到程序中:

- 以密码或个人信息的形式直接从用户处获取

- 由应用程序访问数据库或者其他数据存储器

- 从合作伙伴或其他第三方间接获取

通常,在移动环境下,此私人信息除了包括密码、SSN 和其他常规个人信息之外,还包括以下信息:

- 位置

- 手机号码

- 序列号和设备 ID

- 网络运营商信息

- 语音信箱信息


有时,未贴上私人标签的数据在其他上下文中也有可能成为私人信息。例如,学生的学号通常不视为私人信息,因为学号中并没有明确且公开可用的信息来反映学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然不安全地处理私人数据有多种形式,但是常见的风险来自于盲目的信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

为能够妥善应对此类备受瞩目的信息盗取事件,私人数据的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

这些规范业已存在,但侵犯隐私的情况仍时有发生。

Abstract
这种标识函数错误地处理了机密信息。此程序会危及到用户的个人隐私。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到了一个外部介质,例如控制台、file system 或网络。
示例 1:以下代码会从移动设备中检索地理位置信息并将其发送到服务器,同时记录到该设备中。虽然许多开发人员认为日志文件是存储所有数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
[locationManager startUpdatingLocation];
CLLocation *location = [locationManager location];
// Configure the new event with information from the location
CLLocationCoordinate2D coordinate = [location coordinate];

NSString *latitude = [NSString stringWithFormat:@"%f", coordinate.latitude];
NSString *longitude = [NSString stringWithFormat:@"%f", coordinate.longitude];

NSLog(@"dLatitude : %@", latitude);
NSLog(@"dLongitude : %@",longitude);

NSString *urlWithParams = [NSString stringWithFormat:TOKEN_URL, latitude, longitude];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlWithParams]];
[request setHTTPMethod:@"GET"];
[[NSURLConnection alloc] initWithRequest:request delegate:self];


当设备丢失或被盗时,就会产生有关维护系统信息的其他方面的忧虑。攻击者一旦拥有 iOS 设备之后,即可通过对设备进行 USB 连接来访问其中的大量数据。iOS 属性列表 (plist) 及 SQLite 数据库等文件很容易访问,可能会泄露个人信息。通常的做法是,不要将相关的隐私信息存储在文件系统中不受保护的位置。

示例 2:下列代码向用户默认值列表中添加了一个密码条目,并立即将其存储在一个 plist 文件中。


NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

// Add password to user defaults
[defaults setObject:@"Super Secret" forKey:@"passwd"];

[defaults synchronize];


可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取。

— 由应用程序访问数据库或者其他数据存储形式。

— 间接地从合作者或者第三方处获取。

- 从移动数据存储中检索如下信息:地址簿、拍摄的照片、地理位置、配置文件(包括 plist)、存档的 SMS 消息等。

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号就应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就会带来额外的风险。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。然而,尽管某些特定资源已经被限制访问,但仍无法保证所有能够访问该资源的个体都是可以信赖的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到了一个外部介质,例如控制台、file system 或网络。
示例 1:以下代码包含了一个日志记录语句,该语句通过在日志文件中存储记录信息跟踪添加到数据库中的各条记录信息。在存储的其他数值中,有一个是 getPassword() 函数的返回值,该函数会返回与该帐户关联且由用户提供的明文密码。


<?php
$pass = getPassword();
trigger_error($id . ":" . $pass . ":" . $type . ":" . $tstamp);
?>
Example 1 中的代码会将明文密码记录到应用程序的事件日志中。虽然许多开发人员认为事件日志是存储数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取

— 由应用程序访问数据库或者其他数据存储形式

— 间接地从合作者或者第三方处获取

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到外部位置,如控制台、file system 或网络。
示例:以下代码向一个 Web 用户发送帐户凭证。在此,OWA_SEC.get_password() 函数会返回一个与用户帐户相关并且由用户提供的明文密码,这个密码将输出给 HTTP 响应。

...
HTP.htmlOpen;
HTP.headOpen;
HTP.title (.Account Information.);
HTP.headClose;
HTP.bodyOpen;
HTP.br;
HTP.print('User ID: ' ||
OWA_SEC.get_user_id || '
');
HTP.print('User Password: ' ||
OWA_SEC.get_password || '
');
HTP.br;
HTP.bodyClose;
HTP.htmlClose;
...


其他例子中可能也会存在这样的情况,即,将明文密码通过日志记录语句存储到文件系统中。虽然许多开发人员认为文件系统是存储数据的安全位置,但这不是绝对的,特别是在涉及到隐私问题时。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取

— 由应用程序访问数据库或者其他数据存储形式

— 间接地从合作者或者第三方处获取

desc.dataflow.sql.privacy_violation
Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到了一个外部介质,例如控制台、file system 或网络。
示例 1:以下代码包含了一个日志记录语句,该语句通过在日志文件中存储记录信息跟踪添加到数据库中的各条记录信息。在存储的其他数值中,有一个是 getPassword() 函数的返回值,该函数会返回与该帐户关联且由用户提供的明文密码。


pass = getPassword();
logger.warning('%s: %s %s %s', id, pass, type, tsstamp)
Example 1 中的代码会将明文密码记录到应用程序的事件日志中。虽然许多开发人员认为事件日志是存储数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取

— 由应用程序访问数据库或者其他数据存储形式

— 间接地从合作者或者第三方处获取

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1.用户私人信息进入了程序。

2.数据被写到了一个外部介质,例如控制台、file system 或网络。
示例 1:以下代码包含一个日志记录语句,该语句通过在日志文件中存储添加到数据库中的各条记录信息来跟踪这些信息。


val pass = getPassword()
...
dbmsLog.println(id+":"+pass+":"+type+":"+tstamp)
Example 1 中的代码会将明文密码记录到文件系统中。虽然许多开发人员认为文件系统是存储数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

可以通过多种方式将私人数据输入到程序中:

- 以密码或个人信息的形式直接从用户处获取

- 由应用程序访问数据库或者其他数据存储形式

- 直接从合作伙伴或第三方获取

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
这种标识函数错误地处理了机密信息。此程序会危及到用户的个人隐私。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到了一个外部介质,例如控制台、file system 或网络。
示例 1:以下代码会从移动设备中检索地理位置信息并将其发送到服务器,同时记录到该设备中。虽然许多开发人员认为日志文件是存储所有数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

import CoreLocation
...
var locationManager : CLLocationManager!
var seenError : Bool = false
var locationFixAchieved : Bool = false
var locationStatus : NSString = "Not Started"

seenError = false
locationFixAchieved = false
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.locationServicesEnabled
locationManager.desiredAccuracy = kCLLocationAccuracyBest

locationManager.startUpdatingLocation()

...

if let location: CLLocation! = locationManager.location {
var coordinate : CLLocationCoordinate2D = location.coordinate

let latitude = NSString(format:@"%f", coordinate.latitude)
let longitude = NSString(format:@"%f", coordinate.longitude)

NSLog("dLatitude : %@", latitude)
NSLog("dLongitude : %@",longitude)

let urlString : String = "http://myserver.com/?lat=\(latitude)&lon=\(longitude)"
let url : NSURL = NSURL(string:urlString)
let request : NSURLRequest = NSURLRequest(URL:url)
var err : NSError?
var response : NSURLResponse?
var data : NSData = NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error:&err)
} else {
println("no location...")
}


当设备丢失或被盗时,就会产生有关维护系统信息的其他方面的忧虑。攻击者一旦拥有 iOS 设备之后,即可通过对设备进行 USB 连接来访问其中的大量数据。iOS 属性列表 (plist) 及 SQLite 数据库等文件很容易访问,可能会泄露个人信息。通常的做法是,不要将相关的隐私信息存储在文件系统中不受保护的位置。

示例 2:下列代码向用户默认值列表中添加了一个密码条目,并立即将其存储在一个 plist 文件中。


let defaults : NSUserDefaults = NSUserDefaults.standardUserDefaults()

// Add password to user defaults
defaults.setObject("Super Secret" forKey:"passwd")

defaults.synchronize()


可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取。

— 由应用程序访问数据库或者其他数据存储形式。

— 间接地从合作者或者第三方处获取。

- 从移动数据存储中检索如下信息:地址簿、拍摄的照片、地理位置、配置文件(包括 plist)、存档的 SMS 消息等。

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号就应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就会带来额外的风险。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。然而,尽管某些特定资源已经被限制访问,但仍无法保证所有能够访问该资源的个体都是可以信赖的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
对私人信息(如用户名、密码或社会保障号码)处理不当会损害用户隐私,这通常是一种非法行为。
Explanation

Privacy Violation 会在以下情况下发生:
1.应用程序或程序对私人用户信息处理不当。
2.数据被写到外部位置,如控制台、文件系统、网络或日志文件。

虽然许多开发人员认为本地存储是存储数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。
可以通过多种方式将私人数据输入到程序中:
- 以密码或个人信息的形式直接从用户处获取
- 由应用程序访问数据库或者其他数据存储器
- 从合作伙伴或其他第三方间接获取

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。
虽然不安全地处理私人数据有多种形式,但是常见的风险来自于盲目的信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。
为能够妥善应对此类备受瞩目的信息盗取事件,私人数据的收集与管理正日益规范化。各组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:
- Safe Harbor Privacy Framework [3]
- Gramm-Leach Bliley Act (GLBA) [4]
- Health Insurance Portability and Accountability Act (HIPAA) [5]
- California SB-1386 [6]
这些规范业已存在,但侵犯隐私的情况仍时有发生。

Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到了一个外部介质,例如控制台、file system 或网络。
示例 1:以下代码包含了一个日志记录语句,该语句通过在日志文件中存储记录信息跟踪添加到数据库中的各条记录信息。getPassword 函数可以从存储的其他值中返回一个由用户提供的、与该用户帐户相关的明文密码。


pass = getPassword
...
App.EventLog id & ":" & pass & ":" & type & ":" &tstamp, 4
...
Example 1 中的代码会将明文密码记录到应用程序的事件日志中。虽然许多开发人员认为事件日志是存储数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取

— 由应用程序访问数据库或者其他数据存储形式

— 间接地从合作者或者第三方处获取

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
创建私有或敏感文档的搜索索引可能会损害用户隐私。
Explanation
不安全的索引会威胁到网站和移动应用程序的数据机密性,而这些网站和移动应用程序需要通过索引来实现高效的全文搜索;在 Android 搜索引擎索引的文档中包含私有或机密数据,这可能会导致有关数据存在和内容的信息泄露。在索引过程中,会收集和存储信息。攻击者稍后可以检索到此信息(尽管并不容易),通常是通过对 Android 移动设备上的搜索工具进行一系列查询。

AppSearch 库是一个高性能的 Android 设备端搜索解决方案,它是数据索引的一个典型示例,特别是当某个应用程序有助于在设备上建立系统范围中央索引(称为平台存储)时。中央索引内的数据访问仅限于应用程序贡献的数据,以及其他应用程序通过适当的权限授予显式共享的数据。如果错误地或意外地使用此过程对特定机密文档建立了索引,则可能会因允许搜索该文档而导致隐私侵犯。

示例 1:以下代码显示的示例展示了如何使用 AppSearch 库在 Android 上对私有文档建立索引。该文档包含私有数据,这些数据应在索引过程中隐藏,且不允许 AppSearch 代码访问。


...
// Document object to index
val doc = Doc(
namespace="user1",
id="noteId",
score=10,
text="This document contains private data"
)
// Adding document object to AppSearch index
val putRequest = PutDocumentsRequest.Builder().addDocuments(doc).build()

Abstract
对机密信息(如客户密码或社会保障号码)处理不当会危及用户的个人隐私,这是一种非法行为。
Explanation
Privacy Violation 会在以下情况下发生:

1. 用户私人信息进入了程序。

2. 数据被写到了一个外部介质,例如控制台、file system 或网络。

在这种情况下,数据使用 SharedPreferences类保存在物理 Android 设备上。

例 1:下列代码用 Android 的 SharedPreferences 类存储用户首选项。在存储的其他值中,用户提供的 password 以明文形式存储在设备上。


SharedPreferences userPreferences = this.getSharedPreferences("userPreferences", MODE_WORLD_READABLE);
SharedPreferences.Editor editor = userPreferences.editor();
editor.putString("username", userName);
editor.putString("password", password);
...
editor.language("language", language);
...


虽然默认情况下 Android 的 SharedPreferences 实例是应用程序专用的,无法由其他应用程序访问,但对该设备进行物理访问时可能会允许访问这些文件。此外,在Example 1 中,如果将模式设为 MODE_WORLD_READABLE,则会使首选项文件可供其他应用程序使用,从而会进一步侵犯用户隐私。

虽然许多开发人员认为 file system 是存储数据的安全场所,但是不应对其予以绝对的信任,特别是在涉及到隐私问题时。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取

— 由应用程序访问数据库或者其他数据存储形式

— 间接地从合作者或者第三方处获取

通常,在移动环境下,此私人信息除了包括密码、SSN 和其他常规个人信息之外,还包括以下信息:

- 位置

- 手机号码

- 序列号和设备 ID

- 网络运营商信息

- 语音信箱信息

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在一定风险了。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。尽管已经限制了某些资源的访问权限,但仍无法保证所有访问这些资源的个体都是值得信任的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
应用程序可能会泄露通过 SSL/TLS 支持的通道传输的 HTTP 响应中所包含的敏感数据。
Explanation
此类攻击属于旁路攻击,它通过自适应超文本压缩的浏览器进行勘测与渗透 (BREACH),即使采用 SSL/TLS 通道传输,攻击者还是可以从 HTTP 响应中窃取到敏感信息。目前所有的 SSL/TLS 版本和密码都容易受到这种攻击。如果满足以下三个条件,攻击者就能成功对应用程序执行 BREACH 攻击:

1. 应用程序在响应中传输密钥(例如,反 CSRF 标记)。
2. 应用程序在包含密钥的相同响应中反映用户输入。
3. 配置 Web 服务器以使用 HTTP 压缩。

使用 gzip 压缩的响应大小取决于在其内容中观察到的重复量。因此,字符的重复频率越高,响应就越小。这使攻击者可以使用 HTTP 压缩作为攻击工具,它能指出攻击者通过返回的参数值向应用程序提供的猜测是否正确。如果猜到的字符与密钥中的对应字符一致,则压缩的响应就比较小。攻击者可使用此过程通过对每个请求的压缩率进行分析,逐字符获得整个密钥。

即使应用程序配置为通过安全渠道来提供内容,攻击者也可使用此技术从 HTTP 响应中提取密钥。

要评估应用程序是否容易受到 BREACH 攻击,首先应查看应用程序是否配置为支持 HTTP 压缩。如果是,则对于包含待保护密钥的每个响应,评估其是否包含用户输入。

由于 Django 应用程序配置为使用 CSRF 标记和 GZip 压缩,因此已报告此问题:


MIDDLEWARE_CLASSES = (
...
'django.middleware.csrf.CsrfViewMiddleware',
'django.middleware.gzip.GZipMiddleware',
...

Abstract
标识函数错误地处理了健康状况信息。 此程序可能会泄露用户的个人隐私。
Explanation
以下情况下可能会泄露私人健康状况信息:

1. 用户的健康状况信息进入了程序。

2. 数据被写到外部位置,例如控制台、文件系统或网络。
示例 1:以下代码会从 HealthKit 存储中检索用户的血型,将其发送到服务器并记录到设备中。虽然许多开发人员认为日志文件是存储所有数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

...
HKHealthStore healthStore = new HKHealthStore();
HKBloodTypeObject blood = healthStore.GetBloodType(null);

NSLog("%@", blood.BloodType);

var urlWithParams = String.format(TOKEN_URL, block.BloodType);
var responseString = await client.GetStringAsync(urlWithParams);
...


注意: Apple Logging API 比 NSLog 函数所处的等级更低,开发人员可借助前者创建能够读取设备上所有日志的应用程序,即便他们并不拥有其他应用程序也是如此。

当设备丢失或被盗时,就会产生有关维护用户数据隐私的其他方面的忧虑。 攻击者一旦拥有 iOS 设备,即可通过对设备进行 USB 连接来访问其中的大量数据。 iOS Property Lists (plist) 及 SQLite 数据库等文件很容易访问,可能会泄露个人信息。 通常的做法是,不应将私人健康状况详细信息存储在文件系统中不受保护的位置。

示例 2: 以下代码向用户默认值列表中添加了用户的血型,并立即将其存储在一个 plist 文件中。


...
HKHealthStore healthStore = new HKHealthStore();
HKBloodTypeObject blood = healthStore.GetBloodType(null);

// Add blood type to user defaults
NSUserDefaults.StandardUserDefaults.SetString(blood.BloodType, "bloodType");
...


鉴于私人数据往往被错误处理,私人数据的收集与管理正日益规范化。 在健康状况信息方面,组织可能要遵守下列一项或若干项联邦和州的法规:

- Safe Harbor Privacy Framework [2]

- Gramm-Leach Bliley Act (GLBA) [3]

- Health Insurance Portability and Accountability Act (HIPAA) [4]

- California SB-1386 [5]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

desc.dataflow.dotnet.privacy_violation_health_information
Abstract
该函数错误地处理了健康状况信息。此程序会危及到用户的个人隐私。
Explanation
以下情况下可能会泄露私人健康状况信息:

1. 用户的健康状况信息进入了程序。

2. 数据被写到了一个外部介质,例如控制台、file system 或网络。
示例 1:以下代码会从 HealthKit 存储中检索用户的血型,将其发送到服务器并记录到设备中。虽然许多开发人员认为日志文件是存储所有数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时。

...
HKHealthStore *healthStore = [[HKHealthStore alloc] init];
HKBloodTypeObject *blood = [healthStore bloodTypeWithError:nil];

NSLog(@"%@", [blood bloodType]);

NSString *urlWithParams = [NSString stringWithFormat:TOKEN_URL, [blood bloodType]];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlWithParams]];
[request setHTTPMethod:@"GET"];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
...


注意:Apple Logging API 比 NSLog 函数位于更底层的位置,开发者可借助前者创建能够读取设备上所有日志的应用程序,即便他们并不拥有其他应用程序。

当设备丢失或被盗时,就会产生有关维护系统信息的其他方面的忧虑。攻击者一旦拥有 iOS 设备之后,即可通过对设备进行 USB 连接来访问其中的大量数据。iOS 属性列表 (plist) 及 SQLite 数据库等文件很容易访问,可能会泄露个人信息。通常的做法是,不要将私人健康状况详细信息存储在文件系统中不受保护的位置。

示例 2:以下代码向用户默认值列表中添加了用户的血型,并立即将其存储在一个 plist 文件中。


...
HKHealthStore *healthStore = [[HKHealthStore alloc] init];
HKBloodTypeObject *blood = [healthStore bloodTypeWithError:nil];

// Add blood type to user defaults
[defaults setObject:[blood bloodType] forKey:@"bloodType"];

[defaults synchronize];
...


鉴于私人数据往往被错误处理,私人数据的收集与管理正日益规范化。对于健康状况信息而言,要求各个组织应遵守下列一项或若干项联邦和州的规定:

- Safe Harbor Privacy Framework [2]

- Gramm-Leach Bliley Act (GLBA) [3]

- Health Insurance Portability and Accountability Act (HIPAA) [4]

- California SB-1386 [5]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
以不安全的方式存储敏感数据,从而使通过检查堆来提取数据成为可能。
Explanation
编程时使用某些样式会导致以不安全的方式存储敏感数据,从而使通过检查堆栈来提取数据成为可能。

示例 1:以下方法从控制台返回密码并将其存储在不安全的 String 对象中。

public static String getPassword() {
String inputPassword = "";
ConsoleKeyInfo nextKey = Console.ReadKey(true);
while (nextKey.Key != Console.ReadKey(true)) {
inputPassword.AppendChar(nextKey.KeyChar);
Console.Write("*");
nextKey = Console.ReadKey(true);
}
return inputPassword;
}


因为 String 是一个不可改变的对象,所以无法使内容失效,这意味着在进行垃圾回收之前能够检查堆的任何人都可以获得敏感数据。

Abstract
将敏感数据存储在 String 对象中使系统无法从内存中可靠地清除数据。
Explanation
如果在使用敏感数据(例如密码、社会保障号码、信用卡号等)后不清除内存,则存储在内存中的这些数据可能会泄漏。然而,通常使用 String 存储敏感数据,因为 String 对象不可改变,只有 JVM 垃圾收集器才能从内存中删除 String 的值,只能由 JVM 垃圾收集器完成。由于除非 JVM 内存不足,否则不需要运行垃圾收集器,因此无法保证垃圾收集何时发生。如果应用程序崩溃,则应用程序的内存转储可能会泄露敏感数据。

例 1:下列代码可将密码从字符数组转换为 String

private JPasswordField pf;
...
final char[] password = pf.getPassword();
...
String passwordAsString = new String(password);

Abstract
将敏感数据存储在 String对象中使系统无法从内存中可靠地清除数据。
Explanation
如果在使用敏感数据(例如密码、社会保障号码、信用卡号等)后不清除内存,则存储在内存中的这些数据可能会泄漏。通常,String用于存储敏感数据,但是因为 String 对象不可改变,所以为其指定新值将创建新的String 并为所指定对象分配新对象的引用。原始值将保留在内存中,直到ARC(自动引用计数)取消分配对象并释放其内存。Swift 在对象的生命周期方面不作保证,其在最近的周边作用域结束时完成。如果攻击者在取消分配对象之前转储内存内容,则可以读取内容。

示例 1:以下代码通过使用 String在内存中存储密码。

let password = passwordTextField.text!
// use the password

Abstract
标识调用使用 HTTP GET(而非 POST)方法将数据发送到服务器。
Explanation
使用 GET 方法的 HTTP 请求允许将 URL 和请求参数缓存到浏览器的 URL 缓存、中间代理和服务器日志中。这可能将敏感信息泄露给不具备相应数据权限的人。
示例 1:以下代码使用 GET HTTP 方法而非 POST 来发送 HTTP 请求。


...
NSString * const USER_URL = @"https://www.somesvr.com/someapp/user";
...
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:USER_URL]];
[request setHTTPMethod:@"GET"];
...
示例 2:如果应用程序使用 NSURLRequest,则默认的 HTTP 方法为 GET。


...
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.apple.com/"]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (theConnection) {
// Create the NSMutableData to hold the received data.
// receivedData is an instance variable declared elsewhere.
receivedData = [[NSMutableData data] retain];
} else {

Abstract
该方法可初始化新的可同步 NSURLCredential,该凭据会分发到所有已同步的设备并存储到 Apple 的 iCloud 环境中。
Explanation
创建包含用户名/密码对或客户端证书形式的用户凭据的 NSURLCredential 实例时,需要定义持久性属性。该属性可能的值如下:

- NSURLCredentialPersistenceNone:不应保存凭据。
- NSURLCredentialPersistenceForSession:只应为此会话存储凭据。
- NSURLCredentialPersistencePermanent:应将凭据存储在密钥链中。
- NSURLCredentialPersistenceSynchronizable:应将凭据永久存储在密钥链中,此外还应根据所拥有的 Apple ID 分配给其他设备。

NSURLCredentialPersistenceSynchronizable 属性说明凭据将会分发,并且会存储到 Apple 的云环境中。将凭据存储在 Apple 的云环境中可能并不是可接受的情况,具体取决于应用程序的隐私要求。

示例 1:以下代码片段创建了一个将会分发到其他设备和 iCloud 的可同步凭据:


...
NSURLCredential *credential = [NSURLCredential credentialWithUser:user password:password persistence:NSURLCredentialPersistenceSynchronizable];
NSURLCredentialStorage *shared = [NSURLCredentialStorage sharedCredentialStorage];
[shared setDefaultCredential:credential forProtectionSpace:protectionSpace];

Abstract
该方法可初始化新的可同步 NSURLCredential,该凭据会分发到所有已同步的设备并存储到 Apple 的 iCloud 环境中。
Explanation
创建包含用户名/密码对或客户端证书形式的用户凭据的 NSURLCredential 实例时,需要定义持久性属性。该属性可能的值如下:

- NSURLCredentialPersistenceNone:不应保存凭据。
- NSURLCredentialPersistenceForSession:只应为此会话存储凭据。
- NSURLCredentialPersistencePermanent:应将凭据存储在密钥链中。
- NSURLCredentialPersistenceSynchronizable:应将凭据永久存储在密钥链中,此外还应根据所拥有的 Apple ID 分配给其他设备。

NSURLCredentialPersistenceSynchronizable 属性说明凭据将会分发,并且会存储到 Apple 的云环境中。将凭据存储在 Apple 的云环境中可能并不是可接受的情况,具体取决于应用程序的隐私要求。

示例 1:以下代码片段创建了一个将会分发到其他设备和 iCloud 的可同步凭据:


...
let credential = NSURLCredential(user:foo, password:password, persistence:.Synchronizable)
let shared = NSURLCredentialStorage.sharedCredentialStorage()
shared.setCredential(credential, forProtectionSpace:protectionSpace)
...

Abstract
对业务报告等敏感信息处理不当会危及到公司隐私,这是一种非法行为。
Explanation
当以未加密格式将敏感数据保存在磁盘上时,则会发生 privacy violation。


例 1:下列 ASPX 代码将通过 XML 数据源 SensitiveXMLData 生成敏感财务信息图表的 DataVisualization 控件实例化:


<asp:Chart ID="Chart1" runat="server" ImageLocation="~/Temporary/Graph"
ImageType="Jpeg" DataSourceID="SensitiveXMLData" ImageStorageMode="UseImageLocation">
<series>
.
.
.
</series>
<chartareas>
<asp:ChartArea Name="ChartArea1">
</asp:ChartArea>
</chartareas>
</asp:Chart>
Example 1 中的代码会指示 Chart 控件生成柱状图的 JPEG 图像,并将其写入临时目录 ~/Temporary/Graph 中。在该控件将此图像写入磁盘后,用户浏览器随后会对该文件发起一次请求,并将其显示给用户。该图像未安全写入磁盘。此外,该代码会假定底层基础架构会保护该文件,使其免受其他用户未经授权的访问。

Abstract
该方法在本地删除了 NSURLCredential 实例,但未能删除存储在其他设备和 iCloud 上的副本。
Explanation
创建包含用户名/密码对或客户端证书形式的用户凭据的 NSURLCredential 实例时,需要定义持久性属性。该属性可能的值如下:

- NSURLCredentialPersistenceNone:不应保存凭据。
- NSURLCredentialPersistenceForSession:只应为此会话存储凭据。
- NSURLCredentialPersistencePermanent:应将凭据存储在密钥链中。
- NSURLCredentialPersistenceSynchronizable:应将凭据永久存储在密钥链中,此外还应根据所拥有的 Apple ID 分配给其他设备。

由于 NSURLCredentialPersistenceSynchronizable 凭据会分发到其他设备和 iCloud,如果未能从所有位置完全删除该凭据,将留下可能会泄露的实例。

示例 1:以下代码片段创建了一个可同步的凭据并使用该凭据,然后在本地删除该凭据,但未能从其他设备和 iCloud 中删除它:


...
// Create the credential
NSURLCredential *credential = [NSURLCredential credentialWithUser:user password:password persistence:NSURLCredentialPersistenceSynchronizable];
NSURLCredentialStorage *shared = [NSURLCredentialStorage sharedCredentialStorage];
[shared setDefaultCredential:credential forProtectionSpace:protectionSpace];

// Use the credential as needed
...

// Removes the credential
[shared removeCredential:credential forProtectionSpace:protectionSpace];
...

Abstract
该方法在本地删除了 NSURLCredential 实例,但未能删除存储在其他设备和 iCloud 上的副本。
Explanation
创建包含用户名/密码对或客户端证书形式的用户凭据的 NSURLCredential 实例时,需要定义持久性属性。该属性可能的值如下:

- NSURLCredentialPersistenceNone:不应保存凭据。
- NSURLCredentialPersistenceForSession:只应为此会话存储凭据。
- NSURLCredentialPersistencePermanent:应将凭据存储在密钥链中。
- NSURLCredentialPersistenceSynchronizable:应将凭据永久存储在密钥链中,此外还应根据所拥有的 Apple ID 分配给其他设备。

由于 NSURLCredentialPersistenceSynchronizable 凭据会分发到其他设备和 iCloud,如果未能从所有位置完全删除该凭据,将留下可能会泄露的实例。

示例 1:以下代码片段创建了一个可同步的凭据并使用该凭据,然后在本地删除该凭据,但未能从其他设备和 iCloud 中删除它:


...
// Create the credential
let credential = NSURLCredential(user:foo, password:password, persistence:.Synchronizable)
let shared = NSURLCredentialStorage.sharedCredentialStorage()
shared.setCredential(credential, forProtectionSpace:protectionSpace)

// Use the credential as needed
...

// Removes the credential
shared.removeCredential(credential, forProtectionSpace:protectionSpace)
...

Abstract
存储但未受保护的个人信息(例如,明文文件中的密码)会危害系统安全性。
Explanation
当用户私人信息存储在不受保护的位置时,将会面临 Privacy Violation 漏洞。
示例 1:下列 XML 将某个用户的私人信息存储在一个 plist 文件中。除存储的其他值外,MyCreditCard 键还会存储由用户提供的、与该帐户相关的纯文本信用卡卡号。



<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>password</key>
<string>BASICSECRET</string>
<key>credentials</key>
<dict>
<key>pin</key>
<string>2345</string>
<key>MyCreditCard</key>
<string>1111 11 2321 1112</string>
<key>MysSn</key>
<string>1111-22-3333</string>
<key>ssn</key>
<string>2345-22-3345</string>
<key>userid</key>
<string>12345</string>
</dict>
</dict>
</plist>

Example 1 中的代码会将移动设备中的私人信息存储在该设备上的一个不受支持的 plist 文件中。虽然许多开发人员认为 plist 文件是存储所有数据的安全位置,但这不是绝对的,特别是涉及到隐私问题时,因为 plist 文件可被持有该设备的任何人读取。

可以通过多种方式将私人数据输入到程序中:

- 以密码或个人信息的形式直接从用户处获取。

- 由应用程序访问数据库或者其他数据存储器。

- 从合作伙伴或其他第三方间接获取。

- 从移动数据存储中检索,包括:通讯簿、拍摄的照片、地理位置、配置文件(包括 plist)、存档的 SMS 消息等。

有时,未贴上私人标签的数据在其他上下文中也有可能成为私人信息。例如,学生的学号通常不视为私人信息,因为学号中并没有明确且公开可用的信息来反映学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就存在额外风险了。

虽然不安全地处理私人数据有多种形式,但是常见的风险来自于盲目的信任。程序员通常会信任运行程序的操作环境,因此认为可以将私人信息存放在文件系统、注册表、plist 内部或其他本地控制的资源中。然而,尽管限制了对某些资源的访问权限,也仍无法保证所有可访问这些资源的个人都是可信赖的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

为能够妥善应对此类备受瞩目的信息盗取事件,私人数据的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

这些规范业已存在,但侵犯隐私的情况仍时有发生。

Abstract
如果还在未采取适当的措施禁用 iOS 键盘缓存机制的情况下允许敏感输入,已识别的字段会错误地处理机密信息。
Explanation
已识别的字段未禁用 iOS 的键盘缓存机制。因此,iOS 将缓存最近输入到字段中的任何敏感信息,以便改善其自动更正功能。

示例 1:将输入到敏感文本字段中的输入存储到系统的键盘缓存中:


ViewController.h
...

@property (nonatomic, retain) IBOutlet UITextField *ssnField;

...
Example 1 中的代码指示该应用程序使用了收集敏感信息的输入控件。由于 iOS 会将输入缓存到文本字段以改善其自动更正功能的性能,因此最近输入到此类输入控件中的任何信息可能会被缓存到保存到文件系统的键盘缓存文件中。由于键盘缓存文件存储在设备上,因此如果该设备丢失,该文件可能被恢复,从而导致泄露其中包含的任何敏感信息。

可以通过多种方式将私人数据输入到程序中:

— 以密码或个人信息的形式直接从用户处获取。

— 由应用程序访问数据库或者其他数据存储形式。

— 间接地从合作者或者第三方处获取。

- 从移动数据存储中检索如下信息:地址簿、拍摄的照片、地理位置、配置文件、存档的 SMS 消息等。

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号就应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就会带来额外的风险。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。然而,尽管某些特定资源已经被限制访问,但仍无法保证所有能够访问该资源的个体都是可以信赖的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

Abstract
如果还在未采取适当的措施禁用 iOS 键盘缓存机制的情况下允许敏感输入,已识别的字段会错误地处理机密信息。
Explanation
已识别的字段未禁用 iOS 的键盘缓存机制。因此,iOS 将缓存最近输入到字段中的任何敏感信息,以便改善其自动更正功能。

示例 1:将输入到敏感文本字段中的输入存储到系统的键盘缓存中:


...
@IBOutlet weak var ssnField: UITextField!
...
Example 1 中的代码指示该应用程序使用了收集敏感信息的输入控件。由于 iOS 会将输入缓存到文本字段以改善其自动更正功能的性能,因此最近输入到此类输入控件中的任何信息可能会被缓存到保存到文件系统的键盘缓存文件中。由于键盘缓存文件存储在设备上,因此如果该设备丢失,该文件可能被恢复,从而导致泄露其中包含的任何敏感信息。

可以通过多种方式将私人数据输入到程序中:

—以密码或个人信息的形式直接从用户处获取。

—由应用程序访问数据库或者其他数据存储形式。

—间接地从合作者或者第三方处获取。

- 从移动数据存储中检索如下信息:地址簿、拍摄的照片、地理位置、配置文件、存档的 SMS 消息等。

有时,某些数据并没有贴上私人数据标签,但在特定的上下文中也有可能成为私人信息。比如,通常认为学生的学号不是私人信息,因为学号中并没有明确而公开的信息用以定位特定学生的个人信息。但是,如果学校用学生的社会保障号码生成学号,那么这时学号就应被视为私人信息。

安全和隐私似乎一直是一对矛盾。从安全的角度看,您应该记录所有重要的操作,以便日后可以鉴定那些非法的操作。然而,当其中牵涉到私人数据时,这种做法就会带来额外的风险。

虽然私人数据处理不当的方式多种多样,但常见风险来自于盲目信任。程序员通常会信任运行程序的操作环境,因此认为将私人信息存放在文件系统、注册表或者其他本地控制的资源中是值得信任的。然而,尽管某些特定资源已经被限制访问,但仍无法保证所有能够访问该资源的个体都是可以信赖的。例如,2004 年,一个不道德的 AOL 员工将大约 9200 万个私有客户电子邮件地址卖给了一个通过垃圾邮件进行营销的境外赌博网站 [1]。

鉴于此类备受瞩目的信息盗取事件,私人信息的收集与管理正日益规范化。要求各个组织应根据其经营地点、所从事的业务类型及其处理的私人数据性质,遵守下列一个或若干个联邦和州的规定:

- Safe Harbor Privacy Framework [3]

- Gramm-Leach Bliley Act (GLBA) [4]

- Health Insurance Portability and Accountability Act (HIPAA) [5]

- California SB-1386 [6]

尽管制定了这些规范,Privacy Violation 漏洞仍时有发生。

Abstract
应用程序在后台运行之前,iOS 将自动进行屏幕截图(即当应用程序处于活动状态时按“主页”按钮)。如果发生以上情况时显示了敏感信息,可能会危及用户的个人隐私。
Explanation
在 iOS 缓存屏幕上的内容之前,已识别的 UIViewController 子类不会实现用于隐藏屏幕元素的相应方法。这将泄露应用程序在后台运行之前已输入到输入控件中的敏感信息。

示例 1:输入到 iOS 文本控件中的输入可能会存储在应用程序在后台运行时捕获的屏幕截图中(即当应用程序处于活动状态时按“主页”按钮)。


ViewController.h
...

@property (nonatomic, retain) IBOutlet UITextField *ssnField;

...
Example 1 中的代码指示该应用程序使用了收集敏感信息的输入控件。由于 iOS 会捕获应用程序在后台运行时其活动视图的屏幕截图以改善动画性能,因此在后台事件期间在此类输入控件中显示的任何信息都可能会被缓存在保存到文件系统的图像内。由于这些屏幕缓存屏幕截图存储在设备上,因此如果该设备丢失,这些屏幕截图可能被恢复,从而导致泄露其中包含的任何敏感信息。

Abstract
该方法在未首先对敏感数据进行适当屏蔽的情况下将其写入公开的 Documents 目录。
Explanation
Documents 目录用于存储非瞬态的应用程序数据,例如用户创建的内容或本地信息,以便使应用程序能够以离线模式运行。如果在应用程序的 Info.plist 文件中设置了 UIFileSharingEnabled,那么该目录中的文件便可以通过 iTunes 访问。如果将敏感数据写入 Documents 目录,这些数据可能会通过未加密的备份或 iTunes 接口泄露。

示例 1:以下代码片段将用户密码以明文写入 Documents 目录中:


...
NSString *docsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *passwd_path = [docsDirectory stringByAppendingPathComponent:@"passwords.txt"];

NSString *password = [user password];
[password writeToFile:passwd_path atomically:YES encoding:NSUTF8StringEncoding error:nil];
...

Abstract
收集敏感信息的一些 API 可能会在用户在输入提示符处输入敏感信息时将其返回给用户,从而对其进行错误处理。
Explanation
某些收集敏感信息的 API 可能会错误地处理该信息,将其返回给用户。

示例 1: 以下代码演示 ASP.NET 中的模型,该模型具有密码属性,但未将 DataType 指定为密码,这表示在显示时,系统会默认显示该属性:


public class User
{
[Required]
public int ID { get; set; }

public string Title { get; set; }

[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public DateTime DateOfEmployment { get; set; }

[DataType(DataType.Currency)]
public decimal Salary { get; set; }

[Required]
public string Username { get; set; }

[Required]
public string Password { get; set; }

...
}


由于Example 1 中的 Password 属性未指定 [DataType(DataType.Password)] 属性,因此默认情况下在 UI 中显示不会隐藏它。

Abstract
收集敏感信息的一些 API 可能会在用户在输入提示符处输入敏感信息时将其返回给用户,从而对其进行错误处理。
Explanation
收集敏感信息的一些 API 可能会将敏感信息返回给用户,从而对其进行错误处理。

示例 1:以下代码演示的 TextField 小组件在用户在输入提示符处输入密码时不会对用户密码进行模糊处理:


class SelectionContainerDisabledExampleApp extends StatelessWidget {
const SelectionContainerDisabledExampleApp({super.key});

@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Center(
child: Column(
children: <Widget>[
TextField(
decoration: InputDecoration(
hintText: "Please enter your password",
),
),
],
),
),
),
);
}
}


由于Example 1 中的 TextField 小组件是在 obscureText 属性设置为 true 的情况下进行实例化的,因此,当用户在“请输入您的密码:”提示符处输入密码时,该密码不会进行模糊显示。

Abstract
收集敏感信息的一些 API 可能会在用户在输入提示符处输入敏感信息时将其返回给用户,从而对其进行错误处理。
Explanation
某些收集敏感信息的 API 可能会错误地处理该信息,将其返回给用户。

示例 1:以下代码演示了如何实例化密码回调对象,当用户在输入提示下输入密码时,该对象不会对密码进行模糊处理:

PasswordCallback pc = new PasswordCallback("Please enter your password: ", true);


由于Example 1 中的 pc 是在其第二个参数 onEcho 设置为 true 的情况下进行实例化的,因此,当用户在“请输入您的密码:”提示下输入密码时,该密码不会进行模糊显示。

Abstract
该标识方法在未首先对敏感数据进行适当屏蔽的情况下将其写入屏幕。
Explanation
已识别的函数可以收集敏感数据而不禁用在输入提示符下将其返回给用户的选项。

示例 1:以下代码演示了如何实例化密码字段对象,当用户在文本字段中键入密码时,该对象不会对密码进行模糊处理:


ViewController.h:
...

@property (nonatomic, retain) IBOutlet UITextField *passwordField;

...

ViewController.m:
...

NSString *password = _passwordField.text;

...


由于Example 1 中的 passwordField 未将其 secureTextEntry 属性设置为 true,因此当用户向文本字段中键入密码时,其密码不会进行模糊显示。

Abstract
密码泄漏会危及系统安全。
Explanation
密码无需对其所有者可见,且不能对他人可见。如果以明文形式显示密码,附近的任何人都能看到,这会危及系统安全。对于计算机安全性,肩窥指利用直接观察技巧来获取信息,例如从某个人的背后窥视。在拥挤的公共环境中,肩窥更有可能得逞。这种威胁主要是针对适用于公共以及私密环境中的移动设备。
