界: Encapsulation

封装即绘制强边界。在 Web 浏览器中,这可能意味着确保您的移动代码不会被其他移动代码滥用。在服务器上,这可能意味着区分已验证数据和未验证数据、区分一个用户的数据和另一个用户的数据,或者区分允许用户查看的数据和不允许用户查看的数据。

System Information Leak: External

Abstract
揭示系统数据或调试信息有助于攻击者了解系统并制定攻击计划。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。
示例 1:以下代码会在屏幕上显示 SAPFTP 版本信息:


...
CALL FUNCTION 'FTP_VERSION'
...
IMPORTING
EXEPATH = p
VERSION = v
WORKING_DIR = dir
RFCPATH = rfcp
RFCVERSION = rfcv
TABLES
FTP_TRACE = FTP_TRACE.

WRITE: 'exepath: ', p, 'version: ', v, 'working_dir: ', dir, 'rfcpath: ', rfcp, 'rfcversion: ', rfcv.
...


根据选定屏幕的配置,此信息可转储到屏幕,也可以直接发送到打印机。在某些情况下,版本信息正好可以准确地告诉攻击者入侵此系统的可能性有多大。同样,错误消息也可以告诉攻击者入侵此系统的可能性究竟有多大。例如,一个数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他的错误消息可以揭示有关该系统的更多间接线索。

Abstract
显示系统数据或调试信息使攻击者能够使用系统信息来计划攻击。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。

示例 1:以下代码会将堆栈跟踪输出到“Debug”控制台或日志文件:


try {
...
}
catch(e:Error) {
trace(e.getStackTrace());
}


依据这一系统配置,该信息可转储到控制台,写入日志文件,或者显示给远程用户。例如,凭借脚本机制,可以轻松将输出信息从“标准错误”或“标准输出”重定向至文件或其他程序。或者,运行程序的系统可能具有将日志发送至远程设备的远程日志记录系统,例如“syslog”服务器。在开发过程中,您无法知道此信息最终可能显示的位置。

在某些情况下,该错误消息恰好可以告诉攻击者入侵这一系统的可能性究竟有多大。例如,一则数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他的错误消息可以揭示有关该系统的更多间接线索。在Example 1 中,搜索路径可能会暗示操作系统的类型、系统上安装了哪些应用程序以及管理员在配置程序时采取了哪些保护措施。

Abstract
揭示系统数据或调试信息可帮助攻击者了解系统并制定攻击计划。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。外部信息泄露会暴露有关操作系统、完整路径名、现有用户名或配置文件位置的特定数据,从而使攻击者有机可乘。与内部信息(攻击者更难访问)泄露相比,外部信息泄露的后果更严重。

示例 1:以下代码会在 Visualforce 页面的 <apex:messages/> 元素中泄露异常信息:


try {
...
} catch (Exception e) {
ApexPages.Message msg = new ApexPages.Message(ApexPages.Severity.FATAL, e.getMessage());
ApexPages.addMessage(msg);
}


该信息可能会显示给远程用户。在某些情况下,该错误消息会告诉攻击者该系统易遭受的确切攻击类型。例如,数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他错误消息可以揭示有关该系统的更多间接线索。

Abstract
揭示系统数据或调试信息有助于攻击者了解系统并制定攻击计划。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。
示例 1:以下代码会通过套接字泄露系统信息:


int sockfd;
int flags;
char hostname[1024];
hostname[1023] = '\0';
gethostname(hostname, 1023);
...
sockfd = socket(AF_INET, SOCK_STREAM, 0);
flags = 0;
send(sockfd, hostname, strlen(hostname), flags);


该信息可能会显示给远程用户。在某些情况下,该错误消息可以准确地告诉攻击者系统容易遭受哪种类型的攻击。例如,一则数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他的错误消息可以揭示有关该系统的更多间接线索。在Example 1 中,搜索路径可能会暗示操作系统的类型、系统上安装了哪些应用程序以及管理员在配置程序时采取了哪些保护措施。

Abstract
揭示系统数据或调试信息有助于攻击者了解系统并制定攻击计划。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。
示例 1:下列代码显示了与导致终端错误的 SQL 命令相关的错误代码 SQLCODE 和错误消息 SQlERRMC


...
EXEC SQL
WHENEVER SQLERROR
PERFORM DEBUG-ERR
SQL-EXEC.
...
DEBUG-ERR.
DISPLAY "Error code is: " SQLCODE.
DISPLAY "Error message is: " SQLERRMC.
...


根据系统配置,该信息可能会转储到控制台、写入日志文件或公开给远程用户。在某些情况下,该错误消息恰好可以告诉攻击者入侵这一系统的可能性究竟有多大。在Example 1 中,可通过一条数据库错误消息来揭示应用程序容易受到 SQL Injection 攻击。其他的错误消息可以揭示有关该系统的更多间接线索。

Abstract
揭示系统数据或调试信息可帮助攻击者了解系统并制定攻击计划。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。

示例 1:以下例子会通过 HTTP 响应泄露系统信息。


func handler(w http.ResponseWriter, r *http.Request) {
host, err := os.Hostname()
...
fmt.Fprintf(w, "%s is busy, please try again later.", host)
}


在某些情况下,该错误消息会告诉攻击者该系统易遭受的确切攻击类型有哪些。例如,数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他错误消息可以揭示有关该系统的更多间接线索。在Example 1 中,泄露的信息可能会暗示有关操作系统类型、系统上安装了哪些应用程序以及管理员在配置程序时采取了哪些保护措施的信息。

Abstract
揭示系统数据或调试信息可帮助攻击者了解系统并制定攻击计划。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。外部信息泄露会暴露有关操作系统、完整路径名、现有用户名或配置文件位置的特定数据,从而使攻击者有机可乘,它比内部信息(攻击者更难访问)泄露更严重。

示例 1:以下代码泄露了 HTTP 响应中的异常信息:


protected void doPost (HttpServletRequest req, HttpServletResponse res) throws IOException {
...
PrintWriter out = res.getWriter();
try {
...
} catch (Exception e) {
out.println(e.getMessage());
}
}


该信息可能会显示给远程用户。在某些情况下,该错误消息会告诉攻击者该系统易遭受的确切攻击类型。例如,数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他错误消息可以揭示有关该系统的更多间接线索。在Example 1 中,泄露的信息可能会暗示有关操作系统类型、系统上安装了哪些应用程序以及管理员在配置程序时采取了哪些保护措施的信息。

信息泄漏也是移动计算环境中的一个问题。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。

示例 2:以下代码可向所有注册的 Android 接收者广播所捕获异常的堆栈跟踪。

...
try {
...
} catch (Exception e) {
String exception = Log.getStackTraceString(e);
Intent i = new Intent();
i.setAction("SEND_EXCEPTION");
i.putExtra("exception", exception);
view.getContext().sendBroadcast(i);
}
...


这是另一种情况,特定于移动环境。大多数移动设备现在执行的是“近场通信”(NFC) 协议,以便使用无线电通信在设备之间快速共享信息。它在设备极为贴近或互相接触时有效。即使 NFC 的通信范围仅局限于几厘米,也可能发生窃听、修改数据以及各种其他类型的攻击情况,因为 NFC 本身并不能确保通信安全。

示例 3:Android 平台为 NFC 提供了支持。以下代码将创建一条消息,该消息会被发送给所在范围内的其他设备。

...
public static final String TAG = "NfcActivity";
private static final String DATA_SPLITTER = "__:DATA:__";
private static final String MIME_TYPE = "application/my.applications.mimetype";
...
TelephonyManager tm = (TelephonyManager)Context.getSystemService(Context.TELEPHONY_SERVICE);
String VERSION = tm.getDeviceSoftwareVersion();
...
NfcAdapter nfcAdapter = NfcAdapter.getDefaultAdapter(this);
if (nfcAdapter == null)
return;

String text = TAG + DATA_SPLITTER + VERSION;
NdefRecord record = new NdefRecord(NdefRecord.TNF_MIME_MEDIA,
MIME_TYPE.getBytes(), new byte[0], text.getBytes());
NdefRecord[] records = { record };
NdefMessage msg = new NdefMessage(records);
nfcAdapter.setNdefPushMessage(msg, this);
...


NFC 数据交换格式 (NDEF) 消息包含类型化数据、URI 或自定义应用程序有效负载。如果该消息包含与应用程序有关的信息(如其名称、MIME 类型或设备软件版本),则此信息可能会泄露给窃听者。

Abstract
揭示系统数据或调试信息有助于攻击者了解系统并制定攻击计划。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。

示例 1:以下代码会通过 HTTP 请求泄露系统信息:


NSString *deviceName = [[UIDevice currentDevice] name];
NSString *baseUrl = @"http://myserver.com/?dev=";
NSString *urlString = [baseUrl stringByAppendingString:deviceName];
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest* request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSError *err = nil;
NSURLResponse* response = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];


该信息可以显示给远程用户。在某些情况下,这个错误消息正好可以准确地告诉攻击者系统被入侵的可能性有多大。例如,一个数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他的错误消息可以揭示有关该系统的更多间接线索。

Abstract
揭示系统数据或调试信息有助于攻击者了解系统并制定攻击计划。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。

示例 1:以下代码会将一个异常写入 HTTP 响应:


<?php
...
echo "Server error! Printing the backtrace";
debug_print_backtrace();
...
?>


依据这一系统配置,该信息可转储到控制台,写入日志文件,或者显示给远程用户。例如,凭借脚本机制,可以轻松将输出信息从“标准错误”或“标准输出”重定向至文件或其他程序。或者,运行程序的系统可能具有将日志发送至远程设备的远程日志记录系统,例如“syslog”服务器。在开发过程中,您无法知道此信息最终可能显示的位置。

在某些情况下,该错误消息会告诉攻击者该系统易遭受的确切攻击类型。例如,数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他错误消息可以揭示有关该系统的更多间接线索。在Example 1 中,泄露的信息可能会暗示有关操作系统类型、系统上安装了哪些应用程序以及管理员在配置程序时采取了哪些保护措施的信息。

揭示系统数据或调试信息有助于攻击者了解系统并制定攻击计划。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。

Abstract
揭示系统数据或调试信息有助于攻击者了解系统并制定攻击计划。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。

示例 1:以下代码会在 HTTP 响应中输出所有系统环境变量:


...
import cgi
cgi.print_environ()
...


依据这一系统配置,该信息可转储到控制台,写入日志文件,或者显示给远程用户。例如,凭借脚本机制,可以轻松将输出信息从“标准错误”或“标准输出”重定向至文件或其他程序。或者,运行程序的系统可能具有将日志发送至远程设备的远程日志记录系统,例如“syslog”服务器。在开发过程中,您无法知道此信息最终可能显示的位置。

在某些情况下,该错误消息会告诉攻击者该系统易遭受的确切攻击类型。例如,数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他错误消息可以揭示有关该系统的更多间接线索。在Example 1 中,泄露的信息可能会暗示有关操作系统类型、系统上安装了哪些应用程序以及管理员在配置程序时采取了哪些保护措施的信息。

Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。

示例 1:以下代码会通过 HTTP 响应泄露系统信息:

Abstract
显示系统数据或调试信息使攻击者能够使用系统信息来计划攻击。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。外部信息泄露会暴露有关操作系统、完整路径名、现有用户名或配置文件位置的特定数据,从而使攻击者有机可乘,它比内部信息(攻击者更难访问)泄露更严重。

示例 1:以下代码泄露了 HTTP 响应中的系统详情:


def doSomething() = Action { request =>
...
Ok(Html(Properties.osName)) as HTML
}


该信息可能会显示给远程用户。在某些情况下,该错误消息会告诉攻击者该系统易遭受的确切攻击类型。例如,数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他错误消息可以揭示有关该系统的更多间接线索。在Example 1 中,泄露的信息可能会暗示有关操作系统类型、系统上安装了哪些应用程序以及管理员在配置程序时采取了哪些保护措施的信息。

Abstract
揭示系统数据或调试信息有助于攻击者了解系统并制定攻击计划。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。

示例 1:以下代码会通过 HTTP 请求泄露系统信息:


let deviceName = UIDevice.currentDevice().name
let urlString : String = "http://myserver.com/?dev=\(deviceName)"
let url : NSURL = NSURL(string:urlString)
let request : NSURLRequest = NSURLRequest(URL:url)

该信息可以显示给远程用户。在某些情况下,这个错误消息正好可以准确地告诉攻击者系统被入侵的可能性有多大。例如,一个数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他的错误消息可以揭示有关该系统的更多间接线索。

Abstract
显示系统数据或调试信息使攻击者能够使用系统信息来计划攻击。
Explanation
当系统数据或调试信息通过套接字或网络连接使程序流向远程机器时,就会发生外部信息泄露。

示例 1:以下代码会将一个异常写入 Response 输出流:


...
If Err.number <>0 then
Response.Write "An Error Has Occurred on this page!<BR>"
Response.Write "The Error Number is: " & Err.number & "<BR>"
Response.Write "The Description given is: " & Err.Description & "<BR>"
End If
...


依据这一系统配置,该信息可转储到控制台,写入日志文件,或者显示给远程用户。例如,凭借脚本机制,可以轻松将输出信息从“标准错误”或“标准输出”重定向至文件或其他程序。或者,运行程序的系统可能具有将日志发送至远程设备的远程日志记录系统,例如“syslog”服务器。在开发过程中,您无法知道此信息最终可能显示的位置。

在某些情况下,该错误消息会告诉攻击者该系统易遭受的确切攻击类型。例如,数据库错误消息可以揭示应用程序容易受到 SQL Injection 攻击。其他错误消息可以揭示有关该系统的更多间接线索。在Example 1 中,泄露的信息可能会暗示有关操作系统类型、系统上安装了哪些应用程序以及管理员在配置程序时采取了哪些保护措施的信息。
