Abstract
프로그램이 null 포인터를 역참조할 가능성이 있기 때문에 조각화 오류가 발생합니다.
Explanation
Null 포인터 예외는 일반적으로 하나 이상의 프로그래머 가정을 위반했을 때 발생합니다. 이 문제는 최소한 역참조 후 검사(check-after-dereference), 검사 후 역참조(dereference-after-check) 및 저장 후 역참조(dereference-after-store)라는 세 가지 문제를 유발합니다. 역참조 후 검사(check-after-dereference) 오류는 포인터가 null인지 검사하기 전에 null이 될 수 있는 포인터를 역참조할 경우 발생합니다. 검사 후 역참조(dereference-after-check) 오류는 프로그램이 null인지 여부를 명시적으로 검사하지만, null인 것으로 알려진 포인터를 역참조할 때 발생합니다. 이 유형의 오류는 철자 오류 또는 프로그래머의 실수로 발생합니다. 저장 후 역참조(dereference-after-store) 오류는 프로그램이 명시적으로 포인터를 null로 설정하고 이를 나중에 역참조할 경우에 발생합니다. 이 오류는 프로그래머가 선언된 상태의 변수를 null로 초기화하여 발생하는 경우가 많습니다.

대부분의 null 포인터 문제는 일반적인 소프트웨어 신뢰도 문제를 야기하지만 공격자가 의도적으로 null 포인터 역참조를 실행할 수 있는 경우 그 결과 발생하는 예외 사항을 활용함으로써 보안 로직을 무시하여 Denial Of Service 공격을 가하거나 차후의 공격을 계획하는 데 유용한 디버깅 정보를 응용 프로그램이 노출하도록 할 수 있습니다.

예제 1: 다음 코드에서 프로그래머는 개체 foonull임을 확인한 다음 잘못 역참조합니다. if문에서 검사할 때 foonull이면 null dereference가 발생하여 null 포인터 예외가 일어납니다.


if (foo is null) {
foo.SetBar(val);
...
}
예제 2: 다음 코드에서 프로그래머는 변수 foonull이 아닌 것으로 가정한 다음 개체를 역참조하여 이 가정을 확인합니다. 그러나 프로그래머는 나중에 foonull에 대해 검사함으로써 가정을 반박합니다. if문에서 검사할 때 foonull이 되면 역참조될 때도 null이 되어 null 포인터 예외가 발생할 수 있습니다. 역참조가 안전하지 않거나 이후의 검사가 필요하지 않게 됩니다.


foo.SetBar(val);
...
if (foo is not null) {
...
}
예제 3: 다음 코드에서 프로그래머는 명시적으로 변수 foonull로 설정합니다. 나중에 프로그래머는 개체의 null 값을 검사하기 전에 foo를 역참조합니다.


Foo foo = null;
...
foo.SetBar(val);
...
}

Abstract
이 응용 프로그램에서 공격자는 신뢰할 수 있는 도메인에서 시작된 것으로 보이는 임의의 콘텐트를 강제로 다운로드하게 하는 URL을 만들 수 있습니다.
Explanation
RFD(Reflected File Download)는 방문 시 신뢰할 수 있는 도메인에서 시작된 것으로 보이는 임의의 콘텐트가 포함된 파일 다운로드를 시작하는 피싱 URL 또는 페이지를 만들 수 있는 취약점입니다. 사용자는 지정된 도메인을 신뢰하기 때문에 다운로드한 파일을 열어 잠재적으로 악성 코드를 실행할 수 있습니다.

공격자가 성공적인 RFD 공격을 실행하려면 다음 요구 사항이 충족되어야 합니다.
- 대상 응용 프로그램이 적절한 검증 또는 인코딩 없이 사용자 입력을 리플렉션합니다. 이것은 페이로드를 주입하는 데 사용됩니다.
- 대상 응용 프로그램이 허용적인 URL을 허용합니다. 따라서 공격자는 다운로드한 파일의 이름과 확장자를 제어할 수 있습니다.
- 대상 응용 프로그램 Content-Disposition 헤더가 잘못 구성되었거나 공격자가 HTTP 응답의 Content-Type 및/또는 Content-Disposition 헤더를 제어할 수 있거나 대상 응용 프로그램에 브라우저에서 기본적으로 렌더링되지 않는 Content-Type이 포함되어 있습니다.

예를 들어 응용 프로그램에서 Spring Web MVC ContentNegotiationManager를 사용하여 다양한 응답 형식을 동적으로 생성하는 경우 RFD 공격을 가능하게 하는 데 필요한 조건을 충족합니다.

ContentNegotiationManager는 요청 경로 확장자를 기반으로 응답 형식을 결정하고 JAF(Java Activation Framework)를 사용하여 클라이언트의 요청 형식과 더 잘 일치하는 Content-Type을 찾도록 구성되었습니다. 또한 클라이언트에서는 요청의 Accept 헤더로 전송되는 미디어 유형을 통해 응답 콘텐트 유형을 지정할 수도 있습니다.

예제 1: 다음 예제에서 이 응용 프로그램은 경로 확장자 전략과 Java Activation Framework로 응답의 콘텐트 유형을 결정할 수 있도록 구성되어 있습니다.


<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorPathExtension" value="true" />
<property name="useJaf" value="true" />
</bean>
예제 2: 다음 예제에서 이 응용 프로그램은 요청의 Accept 헤더로 응답의 콘텐트 유형을 결정할 수 있도록 구성되어 있습니다.


<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="ignoreAcceptHeader" value="false" />
</bean>


참고로 Spring 4.2.1에서 ContentNegotiationManagerFactoryBean 속성은 기본적으로 다음과 같이 설정됩니다.

- useJaf: true
- favorPathExtension: true
- ignoreAcceptHeader: falseExample 1의 구성을 통해 공격자는 다음과 같은 악성 URL을 작성합니다.

http://server/some/resource/endpoint/foo.bat?input=payload

따라서 ContentNegotiationManager는 Java Activation Framework(activation.jar이 클래스 경로에 있는 경우)를 사용하여 지정된 파일 확장자의 미디어 유형을 확인하고 응답의 ContentType 헤더를 그에 따라 설정하려고 합니다. 이 예제에서는 파일 확장자가 "bat"이므로 Content-Type 헤더는 application/x-msdownload입니다(정확한 Content-Type은 서버 OS 및 JAF 구성에 따라 달라질 수 있음). 결과적으로 피해자가 이 악성 URL을 방문하면 피해자의 컴퓨터는 공격자가 제어하는 콘텐트가 포함된 ".bat" 파일 다운로드를 자동으로 시작합니다. 이 파일이 실행되면 피해자 시스템에서 공격자의 페이로드에 지정된 모든 명령이 실행됩니다.

Abstract
사용자 입력이 리소스 ID를 제어하는 것을 허용하면 그렇지 않을 때 보호할 수 있는 시스템 리소스를 공격자가 접근하거나 수정할 수 있습니다.
Explanation
Resource injection 이슈는 다음 두 가지 조건을 만족할 때 발생합니다.

1. 공격자가 시스템 리소스에 접근할 때 사용하는 ID를 지정할 수 있습니다.

예를 들어 공격자는 네트워크 리소스에 연결할 때 사용할 포트 번호를 지정할 수 있습니다.

2. 공격자가 리소스를 지정하여 다른 방법으로는 허용되지 않는 권한을 얻습니다.

예를 들어, 프로그램은 공격자에게 민감한 정보를 제 3의 서버에 전달하는 능력을 부여합니다.



참고: 파일 시스템에 저장된 리소스와 관련이 있는 리소스 삽입은 경로 조작이라는 별도의 범주로 보고됩니다. 이 취약점에 대한 자세한 내용은 path manipulation 설명을 참조하십시오.

예제 1: 다음 코드는 HTTP 요청에서 읽은 호스트 이름을 사용하여 FTP 연결을 만듭니다.


...
host_name = request->get_form_field( 'host' ).
CALL FUNCTION 'FTP_CONNECT'
EXPORTING
USER = user
PASSWORD = password
HOST = host_name
RFC_DESTINATION = 'SAPFTP'
IMPORTING
HANDLE = mi_handle
EXCEPTIONS
NOT_CONNECTED = 1
OTHERS = 2.
...


사용자 입력이 적용되는 리소스는 콘텐트가 위험할 수 있음을 나타냅니다. 예를 들어, 마침표, 슬래시 및 백슬래시 등의 특수 문자가 포함된 데이터는 file system과 상호 작용하는 메서드에 사용하면 위험합니다. 마찬가지로 URL 및 URI가 포함된 데이터도 원격 연결을 설정하는 함수에 사용하면 위험합니다.

사용자 입력이 적용되는 리소스는 콘텐트가 위험할 수 있음을 나타냅니다. 예를 들어, 마침표, 슬래시 및 백슬래시 등의 특수 문자가 포함된 데이터는 file system과 상호 작용하는 메서드에 사용하면 위험합니다. 마찬가지로 URL 및 URI가 포함된 데이터도 원격 연결을 설정하는 함수에 사용하면 위험합니다.

Abstract
사용자 입력이 리소스 ID를 제어하는 것을 허용하면 그렇지 않을 때 보호할 수 있는 시스템 리소스를 공격자가 접근하거나 수정할 수 있습니다.
Explanation
Resource injection 이슈는 다음 두 가지 조건을 만족할 때 발생합니다.

1. 공격자가 시스템 리소스에 접근할 때 사용하는 ID를 지정할 수 있습니다.

예를 들어 공격자는 열려는 파일 이름의 일부 또는 사용할 포트 번호를 지정할 수 있습니다.

2. 공격자가 리소스를 지정하여 다른 방법으로는 허용되지 않는 권한을 얻습니다.

예를 들어, 프로그램이 공격자에게 지정한 파일을 덮어쓰거나 공격자가 제어하는 구성으로 실행할 수 있는 권한을 주는 것입니다.

예제 1: 다음 ColdFusion 코드는 Java ServerSocket 개체를 만들고 HTTP 요청으로 읽어들인 포트 번호를 사용하여 소켓을 만듭니다.


<cfobject action="create" type="java" class="java.net.ServerSocket" name="myObj">
<cfset srvr = myObj.init(#url.port#)>
<cfset socket = srvr.accept()>

Passing user input to objects imported from other languages can be very dangerous.

Abstract
사용자 입력이 리소스 ID를 제어하는 것을 허용하면 그렇지 않을 때 보호할 수 있는 시스템 리소스를 공격자가 액세스하거나 수정할 수 있습니다.
Explanation
Resource Injection 이슈는 다음 두 가지 조건을 만족할 때 발생합니다.

1. 공격자가 시스템 리소스에 액세스할 때 사용하는 ID를 지정할 수 있습니다.

예를 들어 공격자는 특정 포트 번호를 지정하여 네트워크 리소스에 연결할 때 사용할 수 있습니다.

2. 공격자가 리소스를 지정하여 다른 방법으로는 허용되지 않는 권한을 얻습니다.

예를 들어 프로그램이 중요한 정보를 외부 공급업체 서버에 전달하는 권한을 공격자에게 부여할 수 있습니다.



참고: 파일 시스템에 저장된 리소스와 관련이 있는 Resource Injection은 경로 조작이라는 별도의 범주로 보고됩니다. 이 취약성의 추가 세부사항은 Path Manipulation 설명을 참조하십시오.

예제 1: 다음 코드는 HTTP 요청에서 읽어들인 포트 번호를 사용하여 소켓을 생성합니다.


final server = await HttpServer.bind('localhost', 18081);
server.listen((request) async {
final remotePort = headers.value('port');
final serverSocket = await ServerSocket.bind(host, remotePort as int);
final httpServer = HttpServer.listenOn(serverSocket);
});
...


모바일 환경에서는 Resource Injection과 같은 전형적인 웹 응용 프로그램 취약성이 발생하지 않는다고 생각하는 사용자도 있습니다. 자기 자신을 공격하는 사용자는 없을 것이라 여기기 때문입니다. 그러나 모바일 플랫폼의 핵심 요소는 다양한 소스에서 다운로드되어 같은 장치에서 함께 실행되는 응용 프로그램이라는 점을 유념해야 합니다. 즉 금융 응용 프로그램과 맬웨어를 함께 실행할 가능성이 높으므로 프로세스 간 통신을 포함하도록 모바일 응용 프로그램의 공격 표면을 확장해야 합니다.

Abstract
사용자 입력이 리소스 ID를 제어하는 것을 허용하면 그렇지 않을 때 보호할 수 있는 시스템 리소스를 공격자가 접근하거나 수정할 수 있습니다.
Explanation
Resource injection 이슈는 다음 두 가지 조건을 만족할 때 발생합니다.

1. 공격자가 시스템 리소스에 접근할 때 사용하는 ID를 지정할 수 있습니다.

예를 들어 공격자는 네트워크 리소스에 연결할 때 사용할 포트 번호를 지정할 수 있습니다.

2. 공격자가 리소스를 지정하여 다른 방법으로는 허용되지 않는 권한을 얻습니다.

예를 들어, 프로그램은 공격자에게 민감한 정보를 제 3의 서버에 전달하는 능력을 부여합니다.



참고: 사용자가 파일 시스템에 저장된 리소스의 위치를 조작할 수 있는 Resource Injection은 경로 조작이라는 별도의 범주로 보고됩니다. 이 취약점에 대한 자세한 내용은 Path Manipulation 설명을 참조하십시오.

예제 1: 다음 코드는 HTTP 요청에서 읽은 포트 번호를 사용하여 소켓을 생성합니다.


String remotePort = request.getParameter("remotePort");
...
ServerSocket srvr = new ServerSocket(remotePort);
Socket skt = srvr.accept();
...


모바일 환경에서는 Resource Injection과 같은 전형적인 웹 응용 프로그램 취약성이 발생하지 않는다고 생각하는 사용자도 있습니다. 자기 자신을 공격하는 사용자는 없을 것이라 여기기 때문입니다. 그러나 모바일 플랫폼의 핵심 요소는 다양한 소스에서 다운로드되어 같은 장치에서 함께 실행되는 응용 프로그램이라는 점을 유념해야 합니다. 즉 금융 응용 프로그램과 맬웨어를 함께 실행할 가능성이 높으므로 프로세스 간 통신을 포함하도록 모바일 응용 프로그램의 공격 표면을 확장해야 합니다.

예제 2: 다음 코드는 Android 인텐트에서 읽은 URL을 사용하여 WebView에서 페이지를 로드합니다.


...
WebView webview = new WebView(this);
setContentView(webview);
String url = this.getIntent().getExtras().getString("url");
webview.loadUrl(url);
...


사용자 입력이 적용되는 리소스는 콘텐트가 위험할 수 있음을 나타냅니다. 예를 들어, 마침표, 슬래시 및 백슬래시 등의 특수 문자가 포함된 데이터는 file system과 상호 작용하는 메서드에 사용하면 위험합니다. 마찬가지로 URL 및 URI가 포함된 데이터도 원격 연결을 설정하는 함수에 사용하면 위험합니다.

Abstract
사용자 입력이 리소스 ID를 제어하는 것을 허용하면 그렇지 않을 때 보호할 수 있는 시스템 리소스를 공격자가 접근하거나 수정할 수 있습니다.
Explanation
Resource injection 이슈는 다음 두 가지 조건을 만족할 때 발생합니다.

3. 공격자가 시스템 리소스에 액세스할 때 사용하는 ID를 지정할 수 있습니다.

예를 들어 공격자는 네트워크 리소스에 연결할 때 사용할 포트 번호를 지정할 수 있습니다.

4. 공격자가 리소스를 지정하여 다른 방법으로는 허용되지 않는 권한을 얻습니다.

예를 들어, 프로그램은 공격자에게 민감한 정보를 제 3의 서버에 전달하는 능력을 부여합니다.

참고: 파일 시스템에 저장된 리소스와 관련이 있는 리소스 삽입은 경로 조작이라는 별도의 범주로 보고됩니다. 이 취약점에 대한 자세한 내용은 path manipulation 설명을 참조하십시오.

예제 1: 다음 코드는 CGI 환경 변수를 다운로드할 문서의 URL로 사용합니다.


...
filename := SUBSTR(OWA_UTIL.get_cgi_env('PATH_INFO'), 2);
WPG_DOCLOAD.download_file(filename);
...


사용자 입력이 적용되는 리소스는 콘텐트가 위험할 수 있음을 나타냅니다. 예를 들어, 마침표, 슬래시 및 백슬래시 등의 특수 문자가 포함된 데이터는 file system과 상호 작용하는 함수에 사용하면 위험합니다. 마찬가지로 URL 및 URI가 포함된 데이터도 원격 연결을 설정하는 함수에 사용하면 위험합니다.

desc.dataflow.scala.resource_injection
Abstract
공격자는 리소스 ID 인수를 제어할 수 있습니다. 그렇지 않을 때 보호할 수 있는 시스템 리소스를 공격자가 접근하거나 수정할 수 있습니다.
Explanation
Resource injection 이슈는 다음 두 가지 조건을 만족할 때 발생합니다.

1. 공격자가 시스템 리소스에 접근할 때 사용하는 ID를 지정할 수 있습니다.

예를 들어 공격자가 네트워크 리소스 또는 입력 파일의 소스 위치에 연결하는 데 사용할 포트 번호를 지정할 수 있습니다.

2. 공격자가 리소스를 지정하여 다른 방법으로는 허용되지 않는 권한을 얻습니다.

예를 들어, 프로그램은 공격자에게 민감한 정보를 타사 서버에 전달하는 능력을 부여할 수 있습니다.

참고: 파일 시스템에 저장된 리소스와 관련이 있는 리소스 삽입은 경로 조작이라는 별도의 범주로 보고됩니다. 이 취약점에 대한 자세한 내용은 path manipulation 설명을 참조하십시오.

예제 1: 다음 코드는 요청에서 호스트 읽기를 사용합니다.


...
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
var inputStream : NSInputStream?
var outputStream : NSOutputStream?
...
var readStream : Unmanaged<CFReadStream>?
var writeStream : Unmanaged<CFWriteStream>?
let rHost = getQueryStringParameter(url.absoluteString, "host")
CFStreamCreatePairWithSocketToHost(kCFAllocatorDefault, rHost, 80, &readStream, &writeStream);
...
}
func getQueryStringParameter(url: String?, param: String) -> String? {
if let url = url, urlComponents = NSURLComponents(string: url), queryItems = (urlComponents.queryItems as? [NSURLQueryItem]) {
return queryItems.filter({ (item) in item.name == param }).first?.value!
}
return nil
}
...


사용자 입력이 적용되는 리소스는 콘텐트가 위험할 수 있음을 나타냅니다. 예를 들어, 마침표, 슬래시 및 백슬래시 등의 특수 문자가 포함된 데이터는 file system과 상호 작용하는 메서드에 사용하면 위험합니다. 마찬가지로 URL 및 URI가 포함된 데이터도 원격 연결을 설정하는 함수에 사용하면 위험합니다.

Abstract
이 응용 프로그램은 사용자가 제어할 수 있는 매개 변수를 브라우저에서 실행할 JavaScript 콜백 함수로 적용하므로 공격자가 동일한 끝점의 도메인에 있는 모든 페이지에서 임의의 JavaScript 함수를 실행할 수 있게 됩니다.
Explanation
이 응용 프로그램은 공격자가 제어하는 매개 변수를 브라우저에서 실행할 JavaScript 함수의 이름으로 사용합니다. 공격자는 동일한 응용 프로그램의 도메인에 있는 대상 페이지를 프레이밍한 다음 취약한 페이지를 참조하여 대상 페이지에 임의의 JavaScript 함수를 실행하는 악성 사이트를 생성할 수 있습니다. 이 공격의 영향은 몇 가지 악용 제한이 있다는 점을 제외하고 Cross-Site Scripting의 영향과 유사합니다. 영숫자와 점 문자를 콜백 이름으로 사용할 수 있는 경우 공격자가 페이지의 요소를 참조하고 사용할 수 있게 됩니다.

예제 1: 다음 코드는 사용자가 콜백 함수 이름을 제어할 수 있는 JSONP 응답을 생성합니다.


@ControllerAdvice
public class JsonpAdvice extends AbstractJsonpResponseBodyAdvice {
public JsonpAdvice() {
super("callback");
}
}
GET /api/latest.json?callback=myCallbackFunction 같은 요청의 경우 컨트롤러 메서드는 다음과 같은 응답을 생성합니다.


HTTP/1.1 200 Ok
Content-Type: application/json; charset=utf-8
Date: Tue, 12 Dec 2017 16:16:04 GMT
Server: nginx/1.12.1
Content-Length: 225
Connection: Close

myCallbackFunction({<json>})


공격자는 JavaScript Script 태그를 사용하여 JSONP 끝점에서 응답을 로드할 수 있으며 이 응답은 myCallbackFunction 함수의 실행으로 이어집니다. 공격자는 다른 콜백 이름을 사용하여 DOM을 탐색하고 상호 작용할 수 있습니다. 예를 들어 opener.document.body.someElemnt.firstChild.nextElementSibling.submit은 대상 페이지에서 폼을 찾고 제출하는 데 사용될 수 있습니다.

Abstract
sanitizeValuefalse로 설정하면 삭제되지 않은 입력이 Cross-Site Scripting과 같은 취약점으로 이어질 수 있습니다.
Explanation
sanitizeValue 속성은 값이 HTML 마크업에 적용될 때 HTML 삭제기를 실행할 것인지 여부를 결정합니다. 입력은 사용자로부터 직접 수신될 수 있으므로 안전하지 않은 것으로 간주될 수 있습니다. sanitizeValue 속성은 추가 입력 문자를 허용하는 등 여러 가지 이유로 인해 false로 설정될 수 있습니다. 하지만 이렇게 하면 안전하지 않은 사용자 입력이 코드에서 부주의로 실행될 수 있습니다. sanitizeValue 속성을 기본값인 true로 설정하는 것이 안전합니다.

예제 1: 다음은 SAPUI5 RichTextEditor에서 sanitizeValue 속성을 false로 설정합니다.

new RichTextEditor({
sanitizeValue: false,
value: input
}).placeAt("moreContent");

Abstract
응용 프로그램은 리소스 URI를 조작하는 데 사용자 제어 데이터를 사용하여 타사 시스템과의 네트워크 연결을 시작합니다.
Explanation
공격자가 응용 프로그램 서버에서 설정된 네트워크 연결에 영향을 미칠 수 있을 때 SSRF(Server-Side Request Forgery)가 발생합니다. 네트워크 연결의 출처는 응용 프로그램 서버 내부 IP 주소가 되며, 공격자는 이 연결을 이용해서 네트워크 제어를 무시하고 원래는 노출되지 않은 내부 리소스를 스캔 또는 공격할 수 있게 됩니다.

예제 1: 다음은 공격자가 서버가 연결하는 URL을 제어할 수 있게 되는 예입니다.


...
lv_uri = request->get_form_field( 'uri' ).
CALL METHOD cl_http_utility=>set_request_uri
EXPORTING
request = lo_request
uri = lv_uri.
...


공격자가 네트워크 연결을 하이재킹하는 능력은 해당 공격자가 제어 가능한 URI의 특정 부분 및 연결에 사용된 라이브러리에 좌우됩니다. 예를 들어, URI 스키마를 제어할 수 있게 되면 공격자는 http 또는 https와는 다른 다음 프로토콜을 사용할 수 있게 됩니다.

- up://
- ldap://
- jar://
- gopher://
- mailto://
- ssh2://
- telnet://
- expect://

이렇게 하이재킹된 네트워크 연결을 이용하여 공격자는 다음과 같은 공격을 수행할 수 있습니다.

- 인트라넷 리소스 포트 스캐닝
- 방화벽 무시
- 응용 프로그램 서버 또는 인트라넷에서 실행 중인 취약 프로그램 공격
- Injection 공격 또는 CSRF를 활용한 내/외부 웹 응용 프로그램 공격
- file:// 스키마를 활용하여 로컬 파일에 접근
- Windows 시스템에서 공격자가 file:// 스키마 및 UNC 경로를 통해 내부 공유 자료에 액세스 및 스캔 가능
- DNS 캐시 감염 공격 수행

Abstract
응용 프로그램은 리소스 URI를 조작하는 데 사용자 제어 데이터를 사용하여 타사 시스템과의 네트워크 연결을 시작합니다.
Explanation
공격자가 응용 프로그램 서버에서 설정된 네트워크 연결에 영향을 미칠 수 있을 때 SSRF(Server-Side Request Forgery)가 발생합니다. 네트워크 연결의 출처는 응용 프로그램 서버 내부 IP가 되며, 공격자는 이 연결을 이용해서 네트워크 제어를 무시하고 원래는 노출되지 않은 내부 리소스를 스캔 또는 공격할 수 있게 됩니다.

예제 1: 다음은 공격자가 서버가 연결하는 URL을 제어할 수 있게 되는 예입니다.


char *url = maliciousInput();
CURL *curl = curl_easy_init();
curl_easy_setopt(curl, CURLOPT_URL, url);
CURLcode res = curl_easy_perform(curl);


공격자가 네트워크 연결을 하이재킹하는 능력은 해당 공격자가 제어 가능한 URI의 특정 부분 및 연결에 사용된 라이브러리에 좌우됩니다. 예를 들어, URI 스키마를 제어할 수 있게 되면 공격자는 http 또는 https와는 다른 다음 프로토콜을 사용할 수 있게 됩니다.

- up://
- ldap://
- jar://
- gopher://
- mailto://
- ssh2://
- telnet://
- expect://

이렇게 하이재킹된 네트워크 연결을 이용하여 공격자는 다음과 같은 공격을 수행할 수 있습니다.

- 인트라넷 리소스 포트 스캐닝
- 방화벽 무시
- 응용 프로그램 서버 또는 인트라넷에서 실행 중인 취약 프로그램 공격
- Injection 공격 또는 CSRF를 활용한 내/외부 웹 응용 프로그램 공격
- file:// 스키마를 사용하는 로컬 파일 액세스
- Windows 시스템에서 공격자가 file:// 스키마 및 UNC 경로를 통해 내부 공유 자료에 액세스 및 스캔 가능
- DNS 캐시 감염 공격 수행

desc.dataflow.java.server_side_request_forgery
Abstract
응용 프로그램은 리소스 URI를 조작하는 데 사용자 제어 데이터를 사용하여 타사 시스템과의 네트워크 연결을 시작합니다.
Explanation
공격자가 응용 프로그램 서버에서 설정된 네트워크 연결에 영향을 미칠 수 있을 때 SSRF(Server-Side Request Forgery)가 발생합니다. 네트워크 연결의 출처는 응용 프로그램 서버 내부 IP 주소가 되며, 공격자는 이 연결을 이용해서 네트워크 제어를 무시하고 원래는 노출되지 않은 내부 리소스를 스캔 또는 공격할 수 있게 됩니다.

예제 1: 다음은 공격자가 서버가 연결하는 URL을 제어할 수 있게 되는 예입니다.


var http = require('http');
var url = require('url');

function listener(request, response){
var request_url = url.parse(request.url, true)['query']['url'];
http.request(request_url)
...
}
...
http.createServer(listener).listen(8080);
...


공격자가 네트워크 연결을 하이재킹하는 능력은 해당 공격자가 제어 가능한 URI의 특정 부분 및 연결에 사용된 라이브러리에 좌우됩니다. 예를 들어, URI 스키마를 제어할 수 있게 되면 공격자는 http 또는 https와는 다른 다음 프로토콜을 사용할 수 있게 됩니다.

- up://
- ldap://
- jar://
- gopher://
- mailto://
- ssh2://
- telnet://
- expect://

이렇게 하이재킹된 네트워크 연결을 이용하여 공격자는 다음과 같은 공격을 수행할 수 있습니다.

- 인트라넷 리소스 포트 스캐닝
- 방화벽 무시
- 응용 프로그램 서버 또는 인트라넷에서 실행 중인 취약 프로그램 공격
- Injection 공격 또는 CSRF를 활용한 내/외부 웹 응용 프로그램 공격
- file:// 스키마를 활용하여 로컬 파일에 액세스
- Windows 시스템에서 공격자가 file:// 스키마 및 UNC 경로를 통해 내부 공유 자료에 액세스 및 스캔 가능
- DNS 캐시 감염 공격 수행

Abstract
응용 프로그램은 리소스 URI를 조작하는 데 사용자 제어 데이터를 사용하여 타사 시스템과의 네트워크 연결을 시작합니다.
Explanation
공격자가 응용 프로그램 서버에서 설정된 네트워크 연결에 영향을 미칠 수 있을 때 SSRF(Server-Side Request Forgery)가 발생합니다. 네트워크 연결의 출처는 응용 프로그램 서버 내부 IP 주소가 되며, 공격자는 이 연결을 이용해서 네트워크 제어 무시하고 원래는 노출되지 않은 내부 리소스를 스캔 또는 공격할 수 있게 됩니다.

예제 1: 다음은 공격자가 서버가 연결하는 URL을 제어할 수 있게 되는 예입니다.


url = request.GET['url']
handle = urllib.urlopen(url)


공격자가 네트워크 연결을 하이재킹하는 능력은 해당 공격자가 제어 가능한 URI의 특정 부분 및 연결에 사용된 라이브러리에 좌우됩니다. 예를 들어, URI 스키마를 제어할 수 있게 되면 공격자는 http 또는 https와는 다른 다음 프로토콜을 사용할 수 있게 됩니다.

- up://
- ldap://
- jar://
- gopher://
- mailto://
- ssh2://
- telnet://
- expect://

이렇게 하이재킹된 네트워크 연결을 이용하여 공격자는 다음과 같은 공격을 수행할 수 있습니다.

- 인트라넷 리소스 포트 스캐닝
- 방화벽 무시
- 응용 프로그램 서버 또는 인트라넷에서 실행 중인 취약 프로그램 공격
- Injection 공격 또는 CSRF를 활용한 내/외부 웹 응용 프로그램 공격
- file:// 스키마를 활용하여 로컬 파일에 접근
- Windows 시스템에서 공격자가 file:// 스키마 및 UNC 경로를 통해 내부 공유 자료에 접근 및 스캔 가능
- DNS 캐시 감염 공격 수행

Abstract
사용자 제어 데이터는 템플릿 엔진의 템플릿으로 사용되어 공격자가 템플릿 컨텍스트에 액세스하고 일부 경우 응용 프로그램 서버에서 임의의 코드를 삽입 및 실행할 수 있도록 합니다.
Explanation
템플릿 엔진은 동적 데이터를 사용하여 콘텐트를 렌더링하는 데 사용됩니다. 이 컨텍스트 데이터는 일반적으로 사용자에 의해 제어되고 웹 페이지, 전자 메일 등을 생성하는 템플릿을 통해 서식이 지정됩니다. 템플릿 엔진을 사용하면 조건절, 루프 등과 같은 코드 생성과 함께 컨텍스트 데이터를 처리함으로써 템플릿에 강력한 언어 식을 사용하여 동적 콘텐트를 렌더링할 수 있습니다. 공격자가 렌더링될 템플릿을 제어할 수 있는 경우 컨텍스트 데이터를 노출하는 식을 삽입하거나 서버에서 임의의 명령을 실행할 수도 있습니다.

예제 1: 다음 예제는 템플릿이 HTTP 요청에서 검색되고 렌더링되는 방법을 보여 줍니다.

// Set up the context data
VelocityContext context = new VelocityContext();
context.put( "name", user.name );

// Load the template
String template = getUserTemplateFromRequestBody(request);
RuntimeServices runtimeServices = RuntimeSingleton.getRuntimeServices();
StringReader reader = new StringReader(template);
SimpleNode node = runtimeServices.parse(reader, "myTemplate");
template = new Template();
template.setRuntimeServices(runtimeServices);
template.setData(node);
template.initDocument();

// Render the template with the context data
StringWriter sw = new StringWriter();
template.merge( context, sw );
Example 1Velocity를 템플릿 엔진으로 사용합니다. 해당 엔진의 경우 공격자가 다음과 같은 템플릿을 제출하여 서버에서 임의의 명령을 실행할 수 있습니다.

$name.getClass().forName("java.lang.Runtime").getRuntime().exec(<COMMAND>)

Abstract
사용자 제어 데이터는 템플릿 엔진의 템플릿으로 사용되어 공격자가 템플릿 컨텍스트에 액세스하고 일부 경우 응용 프로그램 서버에서 임의의 코드를 삽입 및 실행할 수 있도록 합니다.
Explanation
템플릿 엔진은 동적 데이터를 사용하여 콘텐트를 렌더링하는 데 사용됩니다. 이 컨텍스트 데이터는 일반적으로 사용자에 의해 제어되고 웹 페이지, 전자 메일 등을 생성하는 템플릿을 통해 서식이 지정됩니다. 템플릿 엔진을 사용하면 조건절, 루프 등과 같은 코드 생성과 함께 컨텍스트 데이터를 처리함으로써 템플릿에 강력한 언어 식을 사용하여 동적 콘텐트를 렌더링할 수 있습니다. 공격자가 렌더링될 템플릿을 제어할 수 있는 경우 컨텍스트 데이터를 노출하는 식을 삽입하거나 서버에서 임의의 명령을 실행할 수도 있습니다.

예제 1: 다음 예제는 템플릿이 Jinja2 템플릿 엔진을 사용하여 렌더링되고 HTTP 요청에서 검색되는 방법을 보여 줍니다.

from django.http import HttpResponse
from jinja2 import Template as Jinja2_Template
from jinja2 import Environment, DictLoader, escape

def process_request(request):
# Load the template
template = request.GET['template']
t = Jinja2_Template(template)
name = source(request.GET['name'])
# Render the template with the context data
html = t.render(name=escape(name))
return HttpResponse(html)
Example 1Jinja2를 템플릿 엔진으로 사용합니다. 해당 엔진의 경우 공격자가 다음과 같은 템플릿을 제출하여 서버로부터 임의의 파일을 읽을 수 있습니다.

template={{''.__class__.__mro__[2].__subclasses__()[40]('/etc/passwd').read()}}
예제 2: 다음 예제는 템플릿이 Django 템플릿 엔진을 사용하여 렌더링되고 HTTP 요청에서 검색되는 방법을 보여 줍니다.

from django.http import HttpResponse
from django.template import Template, Context, Engine

def process_request(request):
# Load the template
template = source(request.GET['template'])
t = Template(template)
user = {"name": "John", "secret":getToken()}
ctx = Context(locals())
html = t.render(ctx)
return HttpResponse(html)
Example 2Django를 템플릿 엔진으로 사용합니다. 해당 엔진의 경우 공격자가 임의의 명령을 실행할 수 없지만 템플릿 컨텍스트의 모든 개체에 액세스할 수 있습니다. 이 예제에서는 암호 토큰을 컨텍스트에서 사용할 수 있으며 암호 토큰이 공격자에 의해 누출될 수 있습니다.

Abstract
기존의 세션 ID를 무효화하지 않고 사용자를 인증하면 공격자에게 인증된 세션을 도용할 수 있는 기회를 제공합니다.
Explanation
다음의 경우 session fixation 취약점이 발생합니다.

1. 웹 응용 프로그램이 먼저 기존 세션을 무효화하지 않고 사용자를 인증하여 이미 사용자에게 연결되어 있는 세션을 계속 사용하도록 합니다.
2. 공격자가 사용자에게 알려진 세션 ID를 강제로 적용할 수 있기 때문에 사용자가 인증되면 공격자가 인증된 세션에 대한 접근 권한을 갖게 됩니다.

Session fixation 취약점의 일반적인 익스플로이트에서 공격자는 웹 응용 프로그램에 대한 새 세션을 만들어 관련 세션 ID를 기록합니다. 그런 다음 공격자는 기록한 세션 ID를 사용하여 피해자가 서버에 대해 인증을 받도록 하고 공격자는 활성 세션을 통해 피해자의 계정에 대한 접근 권한을 얻습니다.

Spring Security와 같은 일부 프레임워크는 새 세션을 만들 때 기존 세션을 자동으로 무효화합니다. 이 동작을 비활성화하면 응용 프로그램이 이 공격에 취약해질 수 있습니다.

예제 1: 다음 예는 session fixation 보호가 비활성화된 Spring Security로 보호된 응용 프로그램의 조각을 보여줍니다.


<http auto-config="true">
...
<session-management session-fixation-protection="none"/>
</http>


응용 프로그램이 취약하다 하더라도 여기에 기술한 공격이 성공하려면 여러 요인이 공격자에게 유리하게 작용해야 합니다. 즉, 공용 터미널에 대한 접근을 들키지 않는 것, 손상된 세션을 활성 상태로 유지하는 능력 및 공용 터미널에서 취약한 응용 프로그램에 로그인하려는 피해자가 바로 그런 요소입니다. 대부분의 경우 충분한 시간을 투자한다고 했을 때 첫 번째 두 관문은 통과할 수 있습니다. 공용 터미널을 사용하여 취약한 응용 프로그램에 로그인하려는 피해자를 찾는 일도 해당 사이트가 아주 인기 있기만 하면 불가능한 일이 아닙니다. 잘 알려지지 않은 사이트일수록 공용 터미널을 사용하여 로그인하려는 피해자가 있을 확률이 낮고 따라서 앞서 기술한 공격이 성공할 가능성도 낮습니다.

공격자가 session fixation 취약점을 익스플로이트할 때 직면하는 가장 큰 과제는 공격자에게 알려진 세션 ID를 사용하여 피해자가 취약한 응용 프로그램에 대해 인증을 받도록 유도하는 것입니다. Example 1에서는 공격자가 잘 알려지지 않은 웹 사이트 관련 공격에 적합하게 조정할 수 없는 직접적인 방법을 사용하여 이를 수행합니다. 하지만 그렇다고 안심해선 안 됩니다. 공격자는 이 공격의 한계를 극복할 수 있는 여러 가지 수단을 갖고 있습니다. 공격자가 사용하는 가장 흔한 방법은 대상 사이트에서 cross-site scripting 또는 HTTP response splitting 취약점을 이용하는 것입니다[1]. 피해자를 속여 JavaScript 또는 기타 코드를 피해자의 브라우저에 다시 돌려보내는 취약한 응용 프로그램에 악성 요청을 전송하도록 하여 공격자는 피해자가 공격자가 제어하는 세션 ID를 다시 사용하도록 하는 쿠키를 만들 수 있습니다.

쿠키가 주어진 URL과 연결된 최상위 도메인에 연결되어 있다는 것을 주목할 필요가 있습니다. 여러 응용 프로그램이 bank.example.comrecipes.example.com과 같이 같은 최상위 도메인에 있는 경우, 한 응용 프로그램의 취약점 때문에 공격자가 도메인 example.com [2]에 있는 응용 프로그램과의 모든 상호 작용에 사용할 고정 세션 ID로 쿠키를 설정할 수 있습니다.

다른 공격으로는 공격자가 올바른 사이트의 요청을 리디렉션하여 사용자가 악성 사이트를 방문하도록 만드는 DNS 감염 및 관련 네트워크 기반 공격 등이 있습니다. 네트워크 기반 공격은 일반적으로 피해자의 네트워크상에 실제로 존재하거나 네트워크상의 피해 시스템을 제어하는 것과 관련이 있습니다. 이는 원격 익스플로이트가 어렵지만 그 중요성을 간과해서는 안 됩니다. Apache Tomcat의 기본 구현과 같이 세션 관리 메커니즘의 보안이 약할수록 일반적으로 쿠키에서 예상되는 세션 ID를 URL에도 지정할 수 있습니다. 이를 통해 공격자가 악성 URL을 전자 메일로 전송하기만 하면 피해자가 고정 세션 ID를 사용하도록 할 수 있습니다.

desc.config.java.session_fixation
Abstract
기존의 세션 ID를 무효화하지 않고 사용자를 인증하면 공격자가 인증된 세션을 도용할 수 있는 기회를 얻습니다.
Explanation
다음의 경우 session fixation 취약점이 발생합니다.

1. 웹 응용 프로그램이 먼저 기존 세션을 무효화하지 않고 사용자를 인증하여 이미 사용자에게 연결되어 있는 세션을 계속 사용하도록 합니다.

2. 공격자가 사용자에게 알려진 세션 ID를 강제로 적용할 수 있기 때문에 사용자가 인증되면 공격자가 인증된 세션에 대한 접근 권한을 갖게 됩니다.

Session fixation 취약점의 일반적인 익스플로이트에서 공격자는 웹 응용 프로그램에 대한 새 세션을 만들어 관련 세션 ID를 기록합니다. 그런 다음 공격자는 기록한 세션 ID를 사용하여 피해자가 서버에 대해 인증을 받도록 하고 공격자는 활성 세션을 통해 피해자의 계정에 대한 접근 권한을 얻습니다.

예제 1: 다음 코드는 세션 쿠키에 대해 use_strict_mode 속성을 비활성화합니다.

ini_set("session.use_strict_mode", "0");

Abstract
공격자는 Spring 세션 속성을 수정하여 응용 프로그램 로직 남용을 유발할 수 있습니다.
Explanation
@SessionAttributes 주석이 있는 클래스는 Spring이 세션 개체의 모델 속성에 변경 사항을 복제하는 것을 의미합니다. 공격자가 모델 속성 내에 임의 값을 저장할 수 있으면 이러한 변경 사항은 응용 프로그램에서 신뢰할 수 있는 세션 개체로 복제됩니다. 세션 속성이 사용자가 수정할 수 없어야 하는 신뢰할 수 있는 데이터를 사용하여 초기화되는 경우 공격자는 세션 퍼즐링 공격을 수행하여 응용 프로그램 로직을 남용할 수 있습니다.

예제 1: 다음 컨트롤러는 로그인 성공 시 사용자 데이터를 세션에 로드하는 메서드를 포함하고 있습니다.


@Controller
@SessionAttributes("user")
public class HomeController {
...
@RequestMapping(value= "/auth", method=RequestMethod.POST)
public String authHandler(@RequestParam String username, @RequestParam String password, RedirectAttributes attributes, Model model) {
User user = userService.findByNamePassword(username, password);
if (user == null) {
// Handle error
...
} else {
// Handle success
attributes.addFlashAttribute("user", user);
return "redirect:home";
}
}
...
}


다른 컨트롤러는 암호 재설정 기능을 처리합니다. 이 컨트롤러는 클래스에 @SessionAttributes("user") 주석이 있으므로 세션에서 User 인스턴스를 로드하려고 시도하며, 이 인스턴스를 사용하여 암호 재설정 질문을 확인합니다.


@Controller
@SessionAttributes("user")
public class ResetPasswordController {

@RequestMapping(value = "/resetQuestion", method = RequestMethod.POST)
public String resetQuestionHandler(@RequestParam String answerReset, SessionStatus status, User user, Model model) {

if (!user.getAnswer().equals(answerReset)) {
// Handle error
...
} else {
// Handle success
...
}
}
}


개발자는 로그인 프로세스 중에 저장된 세션에서 user 인스턴스를 로드하려고 했습니다. 하지만 Spring은 이 요청을 검사하여 데이터를 모델 user 인스턴스로 바인딩하려고 시도할 것입니다. 받은 요청에 User 클래스에 바인딩될 수 있는 데이터가 포함된 경우, Spring은 받은 데이터를 사용자 세션 속성에 병합할 것입니다. 이 시나리오는 answerReset 쿼리 매개 변수의 임의 답변 및 동일한 값을 모두 제출함으로써 세션에 저장된 값을 재정의하는 방식으로 남용될 수 있습니다. 이러한 방법으로 공격자는 무작위 사용자에 대해 임의의 새 암호를 설정할 수 있습니다.

Abstract
시스템 설정을 외부에서 제어하도록 허용하면 서비스를 손상시키거나 응용 프로그램이 비정상적으로 동작할 수 있습니다.
Explanation
Setting manipulation 취약점은 공격자가 시스템 동작을 규정하고 특정 리소스를 관리하거나 경우에 따라 응용 프로그램의 기능에 영향을 주는 값을 제어할 수 있을 때 발생합니다.



Setting manipulation은 다양한 함수에 적용되기 때문에 이를 완전하게 설명하는 것은 불가능합니다. Setting manipulation 범주에서 다루는 함수 간의 긴밀한 관계를 찾는 것보다 한 걸음 물러나서 공격자가 제어해서는 안 되는 시스템 값의 종류를 생각해 보십시오.

예제 1: 다음 PHP 코드 조각은 HTTP 요청에서 매개 변수를 읽어 이를 서비스 데이터베이스 연결로 설정합니다.


...
taintedConnectionStr = request->get_form_field( 'dbconn_name' ).
TRY.
DATA(con) = cl_sql_connection=>get_connection( `R/3*` && taintedConnectionStr ).
...
con->close( ).
CATCH cx_sql_exception INTO FINAL(exc).
...
ENDTRY.


이 예제에서 공격자는 ABAP DBCON 테이블의 존재하지 않는 데이터베이스 연결을 제공하여 오류를 일으키거나 데이터베이스의 사용 권한이 없는 부분에 연결할 수 있습니다.

일반적으로 사용자가 제공하거나 신뢰할 수 없는 데이터가 중요한 값을 제어하도록 해서는 안 됩니다. 공격자가 이 값을 제어함으로써 항상 즉각적으로 주도권을 얻는 것은 아니지만 공격자의 능력을 과소평가해서는 안 됩니다.

예제 1: 다음 C 코드는 명령줄 매개 변수 중 하나로 숫자를 받아 현재 시스템의 호스트 ID로 설정합니다.


...
sethostid(argv[1]);
...
sethostid()호출을 제대로 수행하기 위해 프로세스에 권한을 부여해야 하지만 권한 없는 사용자도 프로그램을 호출할 수 있습니다. 이 예제의 코드를 사용하면 사용자 입력이 직접 시스템 설정 값을 제어할 수 있습니다. 공격자가 호스트 ID에 악성 값을 제공하면 네트워크상의 해당 시스템을 잘못 식별하거나 다른 의도하지 않은 동작을 일으킬 수 있습니다.

Setting manipulation은 다양한 함수에 적용되기 때문에 이를 완전하게 설명하는 것은 불가능합니다. Setting manipulation 카테고리에서 다루는 함수 간의 긴밀한 관계를 찾는 것보다 한 걸음 물러나서 공격자가 제어해서는 안 되는 시스템 값의 종류를 생각해 보십시오.

예제 1: 다음 COBOL 코드 조각은 터미널에서 값을 읽어 이를 큐 개체에 대한 액세스를 설정하기 위해 사용하는 옵션을 계산하는 데 사용합니다.


...
ACCEPT OPT1.
ACCEPT OPT2
COMPUTE OPTS = OPT1 + OPT2.
CALL 'MQOPEN' USING HCONN, OBJECTDESC, OPTS, HOBJ, COMPOCODE REASON.
...


이 예제에서 공격자는 큐에 대한 단독 액세스 대신 공유된 액세스를 허용하는 옵션을 제공할 수 있습니다.

일반적으로 사용자가 제공하거나 신뢰할 수 없는 데이터가 민감한 값을 제어하도록 해서는 안 됩니다. 공격자가 이 값을 제어함으로써 항상 즉각적으로 주도권을 얻는 것은 아니지만 공격자의 능력을 과소평가해서는 안 됩니다.

Abstract
시스템 설정을 외부에서 제어하도록 허용하면 서비스를 손상시키거나 응용 프로그램이 비정상적으로 동작할 수 있습니다.
Explanation
Setting manipulation 취약점은 공격자가 시스템 동작을 규정하고 특정 리소스를 관리하거나 경우에 따라 응용 프로그램의 기능에 영향을 주는 값을 제어할 수 있을 때 발생합니다.

Setting manipulation은 다양한 함수에 적용되기 때문에 이를 완전하게 설명하는 것은 불가능합니다. Setting manipulation 카테고리에서 다루는 함수 간의 긴밀한 관계를 찾는 것보다 한 걸음 물러나서 공격자가 제어해서는 안 되는 시스템 값의 종류를 생각해 보십시오.

예제 1: 다음 코드는 웹 폼에서 숫자를 읽어 이 숫자를 사용하여 초기화 파일의 시간 초과 값을 설정합니다.


...
<cfset code = SetProfileString(IniPath,
Section, "timeout", Form.newTimeout)>
...
Form.newTimeout의 값이 시간 초과를 지정하는 데 사용되므로 공격자는 상당히 큰 수를 지정하여 응용 프로그램에 대해 denial of service(DoS) 공격을 시도할 수 있습니다.

일반적으로 사용자가 제공하거나 신뢰할 수 없는 데이터가 민감한 값을 제어하도록 해서는 안 됩니다. 공격자가 이 값을 제어함으로써 항상 즉각적으로 주도권을 얻는 것은 아니지만 공격자의 능력을 과소평가해서는 안 됩니다.

Abstract
시스템 설정을 외부에서 제어하도록 허용하면 서비스를 손상시키거나 응용 프로그램이 비정상적으로 동작할 수 있습니다.
Explanation
Setting manipulation 취약점은 공격자가 시스템 동작을 규정하고 특정 리소스를 관리하거나 경우에 따라 응용 프로그램의 기능에 영향을 주는 값을 제어할 수 있을 때 발생합니다.



Setting manipulation은 다양한 함수에 적용되기 때문에 이를 완전하게 설명하는 것은 불가능합니다. Setting manipulation 카테고리에서 다루는 함수 간의 긴밀한 관계를 찾는 것보다 한 걸음 물러나서 공격자가 제어해서는 안 되는 시스템 값의 종류를 생각해 보십시오.

예제 1: 다음 Node.js 코드 조각은 http.IncomingMessage 요청 변수에서 문자열을 읽고 추가 V8 명령줄 플래그를 설정하는 데 사용합니다.


var v8 = require('v8');
...
var flags = url.parse(request.url, true)['query']['flags'];
...
v8.setFlagsFromString(flags);
...


이 예제에서는 공격자가 VM에서 설정되는 다양한 플래그를 일으키게 됩니다. 이렇게 되면 프로그램 충돌 및 잠재적 데이터 손실 등의 예측할 수 없는 동작이 발생할 수 있습니다.

일반적으로 사용자가 제공하거나 신뢰할 수 없는 데이터가 민감한 값을 제어하도록 해서는 안 됩니다. 공격자가 이 값을 제어함으로써 항상 즉각적으로 주도권을 얻는 것은 아니지만 공격자의 능력을 과소평가해서는 안 됩니다.

Abstract
시스템 설정을 외부에서 제어하도록 허용하면 서비스를 손상시키거나 응용 프로그램이 비정상적으로 동작할 수 있습니다.
Explanation
Setting manipulation 취약점은 공격자가 시스템 동작을 규정하고 특정 리소스를 관리하거나 경우에 따라 응용 프로그램의 기능에 영향을 주는 값을 제어할 수 있을 때 발생합니다.

Setting manipulation은 다양한 함수에 적용되기 때문에 이를 완전하게 설명하는 것은 불가능합니다. Setting manipulation 카테고리에서 다루는 함수 간의 긴밀한 관계를 찾는 것보다 한 걸음 물러나서 공격자가 제어해서는 안 되는 시스템 값의 종류를 생각해 보십시오.

예제 1: 다음 코드는 SQL 로그 처리기를 구성하고 사용자가 제어할 수 있는 값을 사용합니다.


...
sqlite3(SQLITE_CONFIG_LOG, user_controllable);
...


일반적으로 사용자가 제공하거나 신뢰할 수 없는 데이터가 민감한 값을 제어하도록 해서는 안 됩니다. 공격자가 이 값을 제어함으로써 항상 즉각적으로 주도권을 얻는 것은 아니지만 공격자의 능력을 과소평가해서는 안 됩니다.

Abstract
응용 프로그램은 사용자가 허용 목록을 정의하도록 허용하므로 사용자가 악의적인 입력을 안전한 입력으로 표시할 수 있습니다.
Explanation
프레임워크에는 취약점으로부터 보호하기 위한 검증을 위한 허용 목록이 있는 경우가 많습니다.

예제 1: 다음은 AngularJS에서 이미지가 검색할 수 있는 링크 유형을 파악하는 데 사용하는 허용 목록을 악의적인 사용자가 설정하도록 허용합니다.

myModule.config(function($compileProvider){
$compileProvider.imgSrcSanitizationWhitelist(userInput);
});


문제가 없는 것처럼 보이지만 사용자가 정규식을 /^(http(s)?|javascript):.*/로 설정하는 경우, 응용 프로그램은 이미지 소스 URL 내에서 인라인 JavaScript의 사용을 허용하므로 Cross-Site Scripting 공격이 발생할 수 있습니다.
다른 허용 목록 인스턴스는 다양한 유형의 모든 공격을 방지할 수 있으며, 특히 비즈니스 논리 취약점과 함께 Cross-Site Scripting, command injection, SQL injection과 같은 삽입 공격을 방지할 수 있습니다.

Abstract
이 응용 프로그램을 사용하면 사용자가 승인 요청을 처리하기 위한 작업을 정의할 수 있어 사기 트랜잭션 또는 권한 에스컬레이션이 발생할 수 있습니다.
Explanation
사용자가 승인 요청 처리 작업을 제어할 수 있도록 허용하면 악의적인 사용자가 합법적인 요청을 거부하거나 사기 요청을 승인할 수 있으므로 데이터 손상, 서비스 거부(DoS) 또는 권한 에스컬레이션이 발생할 수 있습니다.

예제 1: 다음 코드는 외부 사용자 입력이 ProcessWorkitemRequest.setAction() 호출에서 승인 작업을 제어하도록 허용합니다.

void processRequest() {
String workItemId = ApexPages.currentPage().getParameters().get('Id');
String action = ApexPages.currentPage().getParameters().get('Action');

Approval.ProcessWorkitemRequest req = new Approval.ProcessWorkitemRequest();
req.setWorkitemId(workItemId);
req.setAction(action);

Approval.ProcessResult res = Approval.process(req);
...
}


공격자가 이 코드를 악용할 수 있는 한 가지 방법은 처음에 자신의 계정과 관련된 역할이나 액세스 권한을 수정하기 위한 승인 요청을 제출하는 것입니다. 그런 다음 쿼리 매개 변수를 조작하여 요청이 부적절하게 승인되도록 할 수 있으므로 잠재적인 무단 권한 에스컬레이션이 발생할 수 있습니다.

Abstract
응용 프로그램은 사용자가 식 구분 기호를 정의하도록 허용하므로 사용자가 Cross-Site Scripting 보호를 우회할 수 있습니다.
Explanation
사용자가 템플릿 엔진에서 사용되는 구분 기호를 정의하도록 허용하면 이전에 구현된 보호 기능이 더 이상 작동되지 않거나 유효하지 않을 수 있습니다. 가장 양호한 버전의 경우, 기능이 예상대로 작동하지 않거나 정보가 누출될 수 있지만, 악의적인 사용자가 엔진에서 보호 기능을 우회할 수도 있으므로 Cross-Site Scripting 취약점이 발생할 수 있습니다.

예제 1: 다음 코드에서 AngularJS 모듈은 URL 내의 해시에서 정의된 시작 기호를 사용하도록 구성되어 있습니다.



var hash = window.location.hash;
var myStartSymbol = decodeURIComponent(hash.substring(1, hash.length));

myModule.config(function($interpolateProvider){
$interpolateProvider.startSymbol(myStartSymbol);
});


이것은 일반적으로 여러 템플릿 엔진이 함께 작동하도록 활성화하기 위해 수행되며, 자체적으로는 매우 위험하지만([1]) AngularJS 식과 호환되지 않는 엔진이 실행될 수 있으므로 사용자가 일반 검증을 우회하고 브라우저 내에서 자신의 코드를 실행할 수 있게 할 수 있습니다.

Abstract
서비스 호스트의 이 구성 파일은 지나치게 허용적인 도메인 간 정책을 정의합니다.
Explanation
기본적으로, Silverlight 응용 프로그램에는 Silverlight 응용 프로그램이 동일한 도메인에서 나오는 경우에만 서비스의 데이터에 액세스할 수 있도록 하는 동일 출처 정책(Same-Origin Policy)이 적용됩니다. Silverlight에서는 개발자가 호스트의 clientaccesspolicy.xml 구성 파일을 적절히 설정하여 정책을 변경하는 것이 허용됩니다. 그러나, 지나치게 허용적인 도메인 간 정책을 사용하면 악성 응용 프로그램이 부적절한 방법으로 피해자 서비스와 통신하여 스푸핑, 데이터 도난, 릴레이 및 기타 공격으로 이어질 수 있기 때문에 설정 변경 시 주의해야 합니다.

예제 1: 다음 구성은 서비스와 통신이 허용되는 도메인을 지정하는 와일드카드를 사용하는 clientaccesspolicy.xml을 보여줍니다.


<allow-from http-request-headers="*">
<domain uri="*"/>
</allow-from>
*domain 요소 uri 속성의 값으로 사용하면 모든 도메인의 응용 프로그램이 서비스에 연결할 수 있음을 나타냅니다.

Abstract
신뢰할 수 없는 소스의 데이터로 SOQL 쿼리를 실행하면 권한이 없는 데이터에 액세스할 수 있습니다.
Explanation
SOQL(Salesforce Object Query Language)은 응용 프로그램 데이터베이스에서 관련 정보를 검색하도록 의도되었습니다. 사용자는 SOQL 쿼리를 사용하여 해당 데이터를 변경할 수 없습니다.

SOQL(Salesforce Object Query Language) injection 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 해당 데이터는 사전 처리 또는 정화 없이 SOQL 쿼리를 동적으로 생성하는 데 사용됩니다.
예제 1: 다음 코드는 지정된 이름을 가진 연락처를 검색하는 SOQL 쿼리를 동적으로 생성하고 실행합니다.


...
public String inputValue {
get { return inputValue; }
set { inputValue = value; }
}
...
String queryString = 'SELECT Id FROM Contact WHERE (IsDeleted = false AND Name like \'%' + inputValue + '%\')';
result = Database.query(queryString);
...


이 코드가 실행하려는 쿼리는 다음과 같습니다.


SELECT Id FROM Contact WHERE (IsDeleted = false AND Name like '%inputValue%')


하지만 상수인 기본 쿼리 문자열과 사용자 입력 문자열을 연결하여 쿼리를 동적으로 생성하기 때문에, 쿼리는 inputValue에 작은따옴표가 들어 있지 않은 경우에만 정확하게 동작합니다. 공격자가 inputValuename') OR (Name like '% 문자열을 입력하면 쿼리는 다음과 같습니다.


SELECT Id FROM Contact WHERE (IsDeleted = false AND Name like '%name') OR (Name like '%%')
name') OR (Name like '% 조건을 추가하면 where 절이 LIKE '%%' 조건을 사용하게 됩니다. 이 조건은 훨씬 간단한 다음 쿼리와 논리적으로 동일하게 되므로 쿼리가 모든 가능한 ID 값을 출력하게 합니다.


SELECT Id FROM Contact WHERE ... OR (Name like '%%')


대부분의 데이터베이스 인터페이스와 달리, force.com 플랫폼의 SOQL은 세미콜론으로 구분된 여러 SOQL 문을 지원하지 않습니다. 이는 일반 SQL injection 공격의 경우에서처럼 여러 명령을 단일 쿼리로 연결할 수 없음을 의미합니다. 또한, Apex 데이터베이스는 주석을 지원하지 않으므로, 모든 작은따옴표, 괄호 또는 기타 특수 문자는 쌍으로 구성되어야 합니다.

Abstract
신뢰할 수 없는 소스의 데이터로 SOSL 쿼리를 실행하면 권한이 없는 데이터에 액세스할 수 있습니다.
Explanation
SOSL(Salesforce Object Search Language)은 레코드에서 텍스트 검색을 수행하는 데 사용되는 Salesforce 플랫폼 검색 언어입니다. SOSL을 사용하여 Salesforce에서 여러 표준 및 사용자 지정 개체 레코드에 걸쳐 필드를 검색합니다.

SOSL(Salesforce Object Search Language) injection 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 해당 데이터는 사전 처리 또는 정화 없이 SOSL 쿼리를 동적으로 생성하는 데 사용됩니다.
예제 1: 다음 코드는 지정된 이름을 가진 연락처를 검색하는 SOSL 쿼리를 동적으로 생성하고 실행합니다.


...
public String inputValue {
get { return inputValue; }
set { inputValue = value; }
}
...
String queryString = 'Name LIKE \'%' + inputValue + '%\'';
String searchString = 'Acme';
String searchQuery = 'FIND :searchString IN ALL FIELDS RETURNING Contact (Id WHERE ' + queryString + ')';
List<List<SObject>> results = Search.query(searchQuery);
...


이 코드가 실행하려는 쿼리는 다음과 같습니다.


String searchQuery = 'FIND :searchString IN ALL FIELDS RETURNING Contact (Id WHERE Name LIKE '%' + inputValue + '%')';


하지만 상수인 기본 쿼리 문자열과 사용자 입력 문자열을 연결하여 쿼리를 동적으로 생성하기 때문에, 쿼리는 inputValue에 작은따옴표가 들어 있지 않은 경우에만 정확하게 동작합니다. 공격자가 inputValue1%' OR Name LIKE ' 문자열을 입력하면 쿼리는 다음과 같습니다.


String searchQuery = 'FIND :searchString IN ALL FIELDS RETURNING Contact (Id WHERE Name LIKE '%1%' OR Name LIKE '%%')';
OR Name like '%%' 조건을 추가하면 where 절이 LIKE '%%' 조건을 사용하므로, 쿼리가 문구 'map'이 포함된 모든 레코드를 출력하게 하며, 훨씬 간단한 다음 쿼리와 논리적으로 동일하게 됩니다.


FIND 'map*' IN ALL FIELDS RETURNING Contact (Id WHERE Name LIKE '%%')


대부분의 데이터베이스 인터페이스와 달리, force.com 플랫폼의 SOSL은 세미콜론으로 구분된 여러 SOSL 문을 지원하지 않습니다. 이는 일반 SQL injection 공격의 경우에서처럼 여러 명령을 단일 쿼리로 연결할 수 없음을 의미합니다. 또한, Apex 데이터베이스는 주석을 지원하지 않으므로, 모든 작은따옴표, 괄호 또는 기타 특수 문자는 쌍으로 구성되어야 합니다.

Abstract
사용자 제어 Bean 정의 리소스를 로드하면 공격자가 서버에서 임의 코드를 실행하거나, 응용 프로그램 로직을 남용하거나, DoS(Denial of Service)를 유발할 수 있습니다.
Explanation
Spring은 개발자가 로컬 파일 및 원격 URL을 포함한 여러 리소스에서 Bean 정의를 로드할 수 있도록 합니다. 공격자가 Bean 정의 리소스의 내용을 제어할 수 있으면 공격자가 초기화 중 임의 코드를 실행할 수 있는 악의적인 Bean 정의를 삽입할 수 있습니다.

예제: 다음 예제는 사용자 제어 위치에서 Bean 정의 리소스를 로드합니다.

String beans = getBeanDefinitionFromUser();
GenericApplicationContext ctx = new GenericApplicationContext();
XmlBeanDefinitionReader xmlReader = new XmlBeanDefinitionReader(ctx);
xmlReader.loadBeanDefinitions(new UrlResource(beans));
ctx.refresh();

Abstract
이 Spring Boot 응용 프로그램은 인증이 필요하지 않은 Actuator 끝점을 사용합니다.
Explanation
Spring Boot 응용 프로그램은 사용자가 응용 프로그램의 다양한 측면을 모니터링하는 데 사용될 수 있는 REST 끝점인 Actuator를 배포하도록 구성될 수 있습니다. 민감한 데이터를 노출할 수 있고 "민감한" 것으로 레이블이 지정된 다양한 기본 제공 엑추에이터가 있습니다. 기본적으로 모든 민감한 HTTP 끝점은 ACTUATOR 역할을 가진 사용자만 액세스할 수 있도록 보호됩니다.

이 응용 프로그램은 민감한 끝점에 대한 인증 요구 사항을 비활성화합니다.

예제 1:


management.security.enabled=false


또는 민감한 끝점을 민감하지 않은 것으로 표시합니다.

예제 2:


endpoints.health.sensitive=false


또는 사용자 지정Actuator가 민감하지 않은 것으로 설정됩니다.


@Component
public class CustomEndpoint implements Endpoint<List<String>> {

public String getId() {
return "customEndpoint";
}

public boolean isEnabled() {
return true;
}

public boolean isSensitive() {
return false;
}

public List<String> invoke() {
// Custom logic to build the output
...
}
}
