Abstract
클래스는 변경할 수 없는 것으로 주석 추가되지만 필드는 final이 아닙니다.
Explanation
이 클래스는 JCIP 주석 패키지의 Immutable 주석으로 주석 추가되었습니다. 비 final 필드는 값이 변경되도록 허용하여 클래스의 불변성을 침해합니다.

예제 1: Immutable 클래스에 대한 다음 코드는 실수로 필드를 final이 아닌 public으로 선언합니다.


@Immutable
public class ImmutableInteger {
public int value;

}

Abstract
표준 의사 난수 발생기는 암호화 공격을 차단하지 못합니다.
Explanation
Insecure Randomness 오류는 보안이 중요한 상황에서 예측 가능한 값을 생성할 수 있는 함수를 난수 발생원으로 사용할 때 발생합니다.

컴퓨터는 결정론을 사용하는 시스템이기 때문에 진정한 무작위성을 구현할 수 없습니다. PRNG(의사 난수 발생기)는 시드로부터 이후의 값을 계산하는 알고리즘을 사용하여 무작위성에 최대한 접근합니다.

PRNG는 두 가지 종류가 있는데 통계적 PRNG 및 암호화 PRNG입니다. 통계적 PRNG는 유용한 통계적 속성을 제공하지만 출력을 쉽게 예측할 수 있고 재생하기 쉬운 숫자 스트림을 만들기 때문에 보안이 예측할 수 없는 값을 생성하는 방식에 의존하는 경우 사용하기 부적합합니다. 암호화 PRNG는 예측하기 어려운 출력을 생성하여 이 문제를 해결합니다. 암호화 값이 안전하려면 공격자가 생성된 무작위 값과 실제적인 무작위 값을 구분하는 것이 불가능하거나 아주 어려워야 합니다. 일반적으로 PRNG 알고리즘이 안전한 암호화로 알려져 있지 않은 경우에는 통계적 PRNG를 가리키는 것일 수 있는데, 이 PRNG는 보안이 중요한 상황일 때 사용해서는 안 됩니다. 이 경우 통계적 PRNG를 사용하면 추측하기 쉬운 임시 암호, 예측 가능한 암호화 키, 세션 하이재킹, DNS 스푸핑 등의 심각한 취약점을 유발할 수 있습니다.

예제 1: 다음 코드는 통계적 PRNG를 사용하여 구입 후 일정 기간 동안 활성 상태를 유지하는 영수증의 URL을 작성합니다.


FORM GenerateReceiptURL CHANGING baseUrl TYPE string.
DATA: r TYPE REF TO cl_abap_random,
var1 TYPE i,
var2 TYPE i,
var3 TYPE n.


GET TIME.
var1 = sy-uzeit.
r = cl_abap_random=>create( seed = var1 ).
r->int31( RECEIVING value = var2 ).
var3 = var2.
CONCATENATE baseUrl var3 ".html" INTO baseUrl.
ENDFORM.


이 코드는 CL_ABAP_RANDOM->INT31 함수를 사용하여 생성되는 영수증 페이지에 대한 "고유한" ID를 생성합니다. CL_ABAP_RANDOM은 통계적 PRNG이므로 생성되는 문자열을 공격자가 쉽게 추축할 수 있습니다. 영수증 시스템의 기본 설계에도 오류가 있지만 암호화 PRNG와 같이 예측 가능한 영수증 ID를 생성하지 않는 난수 발생기를 사용했다면 훨씬 안전했을 것입니다.

}


이 코드는 lrand48() 함수를 사용하여 생성되는 영수증 페이지에 대한 "고유한" ID를 생성합니다. lrand48()은 통계적 PRNG이므로 생성되는 문자열을 공격자가 쉽게 추축할 수 있습니다. 영수증 시스템의 기본 디자인에도 결함이 있지만 예측 가능한 영수증 ID를 생성하지 않는 난수 발생기를 사용하는 것이 보다 안전했을 것입니다.

Abstract
표준 의사 난수 발생기는 암호화 공격을 차단하지 못합니다.
Explanation
Insecure Randomness 오류는 보안이 중요한 상황에서 예측 가능한 값을 생성할 수 있는 함수를 난수 발생원으로 사용할 때 발생합니다.


컴퓨터는 결정론을 사용하는 시스템이기 때문에 진정한 무작위성을 구현할 수 없습니다. PRNG(의사 난수 발생기)는 시드로부터 이후의 값을 계산하는 알고리즘을 사용하여 무작위성에 최대한 접근합니다.

PRNG는 두 가지 종류가 있는데 통계적 PRNG 및 암호화 PRNG입니다. 통계적 PRNG는 유용한 통계적 속성을 제공하지만 출력을 쉽게 예측할 수 있고 재생하기 쉬운 숫자 스트림을 만들기 때문에 보안이 예측할 수 없는 값을 생성하는 방식에 의존하는 경우 사용하기 부적합합니다. 암호화 PRNG는 예측하기 어려운 출력을 생성하여 이 문제를 해결합니다. 암호화 값이 안전하려면 공격자가 생성된 무작위 값과 실제적인 무작위 값을 구분하는 것이 불가능하거나 아주 어려워야 합니다. 일반적으로 PRNG 알고리즘이 안전한 암호화로 알려져 있지 않은 경우에는 통계적 PRNG를 가리키는 것일 수 있는데, 이 PRNG는 보안이 중요한 상황일 때 사용해서는 안 됩니다. 이 경우 통계적 PRNG를 사용하면 추측하기 쉬운 임시 암호, 예측 가능한 암호화 키, 세션 하이재킹, DNS 스푸핑 등의 심각한 취약점을 유발할 수 있습니다.

예제 1: 다음 코드는 통계적 PRNG를 사용하여 구입 후 일정 기간 동안 활성 상태를 유지하는 영수증의 URL을 작성합니다.


<cfoutput>
Receipt: #baseUrl##Rand()#.cfm
</cfoutput>


이 코드는 Rand() 함수를 사용하여 생성되는 영수증 페이지에 대한 "고유한" ID를 생성합니다. Rand()은 통계적 PRNG이므로 생성되는 문자열을 공격자가 쉽게 추축할 수 있습니다. 영수증 시스템의 기본 설계에도 오류가 있지만 암호화 PRNG와 같이 예측 가능한 영수증 ID를 생성하지 않는 난수 발생기를 사용했다면 훨씬 안전했을 것입니다.

Abstract
표준 의사 난수 발생기는 암호화 공격을 차단하지 못합니다.
Explanation
Insecure Randomness 오류는 보안이 중요한 상황에서 예측 가능한 값을 생성할 수 있는 함수를 난수 발생원으로 사용할 때 발생합니다.

컴퓨터는 결정론을 사용하는 시스템이기 때문에 진정한 무작위성을 구현할 수 없습니다. PRNG(의사 난수 발생기)는 시드로부터 이후의 값을 계산하는 알고리즘을 사용하여 무작위성에 최대한 접근합니다.

PRNG는 두 가지 종류가 있는데 통계적 PRNG 및 암호화 PRNG입니다. 통계적 PRNG는 유용한 통계적 속성을 제공하지만 출력을 쉽게 예측할 수 있고 재생하기 쉬운 숫자 스트림을 만들기 때문에 보안이 예측할 수 없는 값을 생성하는 방식에 의존하는 경우 사용하기 부적합합니다. 암호화 PRNG는 예측하기 어려운 출력을 생성하여 이 문제를 해결합니다. 암호화 값이 안전하려면 공격자가 생성된 무작위 값과 실제적인 무작위 값을 구분하는 것이 불가능하거나 아주 어려워야 합니다. 일반적으로 PRNG 알고리즘이 안전한 암호화로 알려져 있지 않은 경우에는 통계적 PRNG를 가리키는 것일 수 있는데, 이 PRNG는 보안이 중요한 상황일 때 사용해서는 안 됩니다. 이 경우 통계적 PRNG를 사용하면 추측하기 쉬운 임시 암호, 예측 가능한 암호화 키, 세션 하이재킹, DNS 스푸핑 등의 심각한 취약점을 유발할 수 있습니다.

예제 1: 다음 코드는 통계적 PRNG를 사용하여 구입 후 일정 기간 동안 활성 상태를 유지하는 영수증의 URL을 작성합니다.


function genReceiptURL (baseURL){
var randNum = Math.random();
var receiptURL = baseURL + randNum + ".html";
return receiptURL;
}


이 코드는 Math.random() 함수를 사용하여 생성되는 영수증 페이지에 대한 "고유한" ID를 생성합니다. Math.random()은 통계적 PRNG이므로 생성되는 문자열을 공격자가 쉽게 추축할 수 있습니다. 영수증 시스템의 기본 설계에도 오류가 있지만 암호화 PRNG와 같이 예측 가능한 영수증 ID를 생성하지 않는 난수 발생기를 사용했다면 훨씬 안전했을 것입니다.

Abstract
표준 의사 난수 발생기는 암호화 공격을 차단하지 못합니다.
Explanation
Insecure randomness 오류는 보안이 중요한 상황에서 예측 가능한 값을 생성할 수 있는 함수를 난수 발생원으로 사용할 때 발생합니다.

컴퓨터는 결정론을 사용하는 시스템이기 때문에 진정한 무작위성을 구현할 수 없습니다. PRNG(의사 난수 발생기)는 시드로부터 이후의 값을 계산하는 알고리즘을 사용하여 무작위성에 최대한 접근합니다.

PRNG는 두 가지 종류가 있는데 통계적 PRNG 및 암호화 PRNG입니다. 통계적 PRNG는 유용한 통계적 속성을 제공하지만 출력을 쉽게 예측할 수 있고 재생하기 쉬운 숫자 스트림을 만들기 때문에 보안이 예측할 수 없는 값을 생성하는 방식에 의존하는 경우 사용하기 부적합합니다. 암호화 PRNG는 예측하기 어려운 출력을 생성하여 이 문제를 해결합니다. 암호화 값이 안전하려면 공격자가 생성된 무작위 값과 실제적인 무작위 값을 구분하는 것이 불가능하거나 아주 어려워야 합니다. 일반적으로 PRNG 알고리즘이 안전한 암호화로 알려져 있지 않은 경우에는 통계적 PRNG를 가리키는 것일 수 있는데, 이 PRNG는 보안이 중요한 상황일 때 사용해서는 안 됩니다. 이 경우 통계적 PRNG를 사용하면 추측하기 쉬운 임시 암호, 예측 가능한 암호화 키, 세션 하이재킹, DNS 스푸핑 등의 심각한 취약점을 유발할 수 있습니다.

예제 1: 다음 코드는 통계적 PRNG를 사용하여 구입 후 일정 기간 동안 활성 상태를 유지하는 영수증의 URL을 작성합니다.


CREATE or REPLACE FUNCTION CREATE_RECEIPT_URL
RETURN VARCHAR2
AS
rnum VARCHAR2(48);
time TIMESTAMP;
url VARCHAR2(MAX_URL)
BEGIN
time := SYSTIMESTAMP;
DBMS_RANDOM.SEED(time);
rnum := DBMS_RANDOM.STRING('x', 48);
url := 'http://test.com/' || rnum || '.html';
RETURN url;
END


이 코드는 DBMS_RANDOM.SEED() 함수를 사용하여 생성되는 영수증 페이지에 대한 "고유한" ID를 생성합니다. DBMS_RANDOM.SEED()은 통계적 PRNG이므로 생성되는 문자열을 공격자가 쉽게 추축할 수 있습니다. 영수증 시스템의 기본 디자인에도 결함이 있지만 예측 가능한 영수증 ID를 생성하지 않는 난수 발생기를 사용하는 것이 보다 안전했을 것입니다.

Abstract
표준 의사 난수 발생기는 암호화 공격을 차단하지 못합니다.
Explanation
Insecure Randomness 오류는 보안이 중요한 상황에서 예측 가능한 값을 생성할 수 있는 함수를 난수 발생원으로 사용할 때 발생합니다.

컴퓨터는 결정론을 사용하는 시스템이기 때문에 진정한 무작위성을 구현할 수 없습니다. PRNG(의사 난수 발생기)는 시드로부터 이후의 값을 계산하는 알고리즘을 사용하여 무작위성에 최대한 접근합니다.

PRNG는 두 가지 종류가 있는데 통계적 PRNG 및 암호화 PRNG입니다. 통계적 PRNG는 유용한 통계적 속성을 제공하지만 출력을 쉽게 예측할 수 있고 재생하기 쉬운 숫자 스트림을 만들기 때문에 보안이 예측할 수 없는 값을 생성하는 방식에 의존하는 경우 사용하기 부적합합니다. 암호화 PRNG는 예측하기 어려운 출력을 생성하여 이 문제를 해결합니다. 암호화 값이 안전하려면 공격자가 생성된 무작위 값과 실제적인 무작위 값을 구분하는 것이 불가능하거나 아주 어려워야 합니다. 일반적으로 PRNG 알고리즘이 안전한 암호화로 알려져 있지 않은 경우에는 통계적 PRNG를 가리키는 것일 수 있는데, 이 PRNG는 보안이 중요한 상황일 때 사용해서는 안 됩니다. 이 경우 통계적 PRNG를 사용하면 추측하기 쉬운 임시 암호, 예측 가능한 암호화 키, 세션 하이재킹, DNS 스푸핑 등의 심각한 취약점을 유발할 수 있습니다.

예제 1: 다음 코드는 통계적 PRNG를 사용하여 구입 후 일정 기간 동안 활성 상태를 유지하는 영수증의 URL을 작성합니다.


def GenerateReceiptURL(baseUrl : String) : String {
val ranGen = new scala.util.Random()
ranGen.setSeed((new Date()).getTime())
return (baseUrl + ranGen.nextInt(400000000) + ".html")
}


이 코드는 Random.nextInt() 함수를 사용하여 생성되는 영수증 페이지에 대한 "고유한" ID를 생성합니다. Random.nextInt()은 통계적 PRNG이므로 생성되는 문자열을 공격자가 쉽게 추축할 수 있습니다. 영수증 시스템의 기본 설계에도 오류가 있지만 암호화 PRNG와 같이 예측 가능한 영수증 ID를 생성하지 않는 난수 발생기를 사용했다면 훨씬 안전했을 것입니다.

Abstract
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 상수 인수로 호출해서는 안 됩니다.
Explanation
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 상수 인수로 호출해서는 안 됩니다. 의사 난수 발생기(예: CL_ABAP_RANDOM 클래스 또는 해당 변형)에서 특정 상수 값을 사용하여 시드가 생성되면 다수의 PRNG 출력을 수집할 수 있는 공격자가 GET_NEXT, INT 및 값을 반환하거나 할당하는 이와 유사한 메서드를 통해 반환되는 값을 예측할 수 있게 됩니다.

예제 1: 발췌한 다음 내용에서는 random_gen2 객체에서 생성되는 값을 random_gen1 객체에서 예측할 수 있습니다.


DATA: random_gen1 TYPE REF TO cl_abap_random,
random_gen2 TYPE REF TO cl_abap_random,

이 예제에서는 의사 난수 발생기 random_gen1random_gen2에서는 동일한 시드 값이 생성되었으므로 var1 = var2입니다.

Abstract
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 상수 인수로 호출해서는 안 됩니다.
Explanation
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 상수 인수로 호출해서는 안 됩니다. 의사 난수 발생기(예: rand())에서 특정 값(srand(unsigned int) 같은 함수 사용)을 사용하여 시드가 생성되면 다수의 PRNG 출력을 수집할 수 있는 공격자가 rand() 및 값을 반환하거나 할당하는 이와 유사한 메서드를 통해 반환되는 값을 예측할 수 있게 됩니다.

예제 1: 첫 번째 2개 블록이 동일한 시드로 시작하므로 의사 난수 발생기(PRNG)가 생성하는 값을 예측할 수 있습니다.


srand(2223333);
float randomNum = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum);
randomNum = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum);

srand(2223333);
float randomNum2 = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum2);
randomNum2 = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum2);

srand(1231234);
float randomNum3 = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum3);
randomNum3 = (rand() % 100);
syslog(LOG_INFO, "Random: %1.2f", randomNum3);


이 예제에서는 randomNum1randomNum2의 결과에서 동일하게 시드가 생성되었기 때문에 의사 난수 발생기 srand(2223333)의 시드를 생성하는 호출이 끝난 후 rand()를 호출할 때마다 동일한 호출 순서로 동일한 출력 결과가 생성됩니다. 예를 들어 출력은 다음과 같을 수 있습니다.


Random: 32.00
Random: 73.00
Random: 32.00
Random: 73.00
Random: 15.00
Random: 75.00


이 결과는 난수와는 거리가 멉니다.

Abstract
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 상수 인수로 호출해서는 안 됩니다.
Explanation
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 상수 인수로 호출해서는 안 됩니다. 의사 난수 발생기(PRNG)에서 특정 값(math.Rand.New(Source) 같은 함수 사용)을 사용하여 시드가 생성되면 다수의 PRNG 출력을 수집할 수 있는 공격자가 math.Rand.Int() 및 값을 반환하거나 할당하는 이와 유사한 메서드를 통해 반환되는 값을 예측할 수 있게 됩니다.

예제 1: 첫 번째 2개 블록이 동일한 시드로 시작하므로 의사 난수 발생기(PRNG)가 생성하는 값을 예측할 수 있습니다.


r := rand.New(rand.NewSource(12345))
i := r.nextInt()

r.Seed(12345)
j := r.nextInt()


이 예에서 PRNG는 동일하게 시드가 생성되었기 때문에 의사 난수 발생기(randomGen.Seed(12345))의 시드를 생성한 호출 이후의 모든 nextInt() 호출은 동일한 출력과 동일한 순서로 나타납니다.

Abstract
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 상수 인수로 호출해서는 안 됩니다.
Explanation
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 상수 인수로 호출해서는 안 됩니다. 의사 난수 발생기(예: Random)에서 특정 값(Random.setSeed() 같은 함수 사용)을 사용하여 시드가 생성되면 다수의 PRNG 출력을 수집할 수 있는 공격자가 Random.nextInt() 및 값을 반환하거나 할당하는 이와 유사한 메서드를 통해 반환되는 값을 예측할 수 있게 됩니다.

예제 1:Random 개체 randomGen2를 통해 생성되는 값을 Random 개체 randomGen1에서 예측할 수 있습니다.


Random randomGen1 = new Random();
randomGen1.setSeed(12345);
int randomInt1 = randomGen1.nextInt();
byte[] bytes1 = new byte[4];
randomGen1.nextBytes(bytes1);

Random randomGen2 = new Random();
randomGen2.setSeed(12345);
int randomInt2 = randomGen2.nextInt();
byte[] bytes2 = new byte[4];
randomGen2.nextBytes(bytes2);


이 예제에서는 의사 난수 발생기 randomGen1randomGen2는 동일하게 시드가 생성되었기 때문에 randomInt1 == randomInt2이고 해당하는 배열 bytes1[]bytes2[]의 값이 같습니다.

Abstract
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 상수 인수로 호출해서는 안 됩니다.
Explanation
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 상수 인수로 호출해서는 안 됩니다. 의사 난수 발생기(예: Random)에서 특정 값(Random(Int) 같은 함수 사용)을 사용하여 시드가 생성되면 다수의 PRNG 출력을 수집할 수 있는 공격자가 Random.nextInt() 및 값을 반환하거나 할당하는 이와 유사한 메서드를 통해 반환되는 값을 예측할 수 있게 됩니다.

예제 1:Random 개체 randomGen2를 통해 생성되는 값을 Random 개체 randomGen1에서 예측할 수 있습니다.


val randomGen1 = Random(12345)
val randomInt1 = randomGen1.nextInt()
val byteArray1 = ByteArray(4)
randomGen1.nextBytes(byteArray1)

val randomGen2 = Random(12345)
val randomInt2 = randomGen2.nextInt()
val byteArray2 = ByteArray(4)
randomGen2.nextBytes(byteArray2)


이 예제에서는 의사 난수 발생기 randomGen1randomGen2는 동일하게 시드가 생성되었기 때문에 randomInt1 == randomInt2이고 해당하는 배열 byteArray1byteArray2의 값이 같습니다.

Abstract
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 상수 정수 인수로 호출해서는 안 됩니다.
Explanation
시드가 전달되어 의사 난수 값을 생성하는 함수는 상수 정수 인수로 호출해서는 안 됩니다. 의사 난수 발생기의 시드를 특정 값을 사용하여 생성하는 경우 반환되는 값을 예측할 수 있습니다.

예제 1: 첫 번째 2개 블록이 동일한 시드로 시작하므로 의사 난수 발생기(PRNG)가 생성하는 값을 예측할 수 있습니다.


...
import random
random.seed(123456)
print "Random: %d" % random.randint(1,100)
print "Random: %d" % random.randint(1,100)
print "Random: %d" % random.randint(1,100)

random.seed(123456)
print "Random: %d" % random.randint(1,100)
print "Random: %d" % random.randint(1,100)
print "Random: %d" % random.randint(1,100)
...


이 예제에서는 PRNG에서 동일하게 시드가 생성되었기 때문에 의사 난수 발생기(random.seed(123456))의 시드를 생성한 호출이 끝난 후 randint()를 호출할 때마다 동일한 호출 순서로 동일한 출력 결과가 생성됩니다. 예를 들어 출력은 다음과 같을 수 있습니다.


Random: 81
Random: 80
Random: 3
Random: 81
Random: 80
Random: 3


이 결과는 난수와는 거리가 멉니다.

Abstract
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 감염된 인수로 호출해서는 안 됩니다.
Explanation
CL_ABAP_RANDOM 클래스 또는 해당 변형을 감염된 인수로 초기화해서는 안 됩니다. 그렇게 하면 공격자가 의사 난수 발생기(PRNG)의 시드 생성에 사용되는 값을 제어할 수 있게 되므로 다음과 같은 메서드(단, 이에 국한하지는 않음)를 호출하여 생성되는 값의 시퀀스를 예측할 수 있게 됩니다. GET_NEXT, INT, FLOAT, PACKED.

Abstract
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 감염된 인수로 호출해서는 안 됩니다.
Explanation
시드(예: srand())가 전달되어 난수 또는 의사 난수(예: rand()) 값을 생성하는 함수는 감염된 인수로 호출해서는 안 됩니다. 그렇게 하면 공격자가 의사 난수 발생기(PRNG)의 시드 생성에 사용되는 값을 제어할 수 있게 되므로 의사 난수 발생기를 호출하여 생성되는 값(대개 정수)의 시퀀스를 예측할 수 있게 됩니다.

Abstract
시드가 전달되어 난수 또는 의사 난수 값을 생성하는 함수는 감염된 인수로 호출해서는 안 됩니다.
Explanation
의사 난수 값(예: random.randint())을 생성하는 함수는 감염된 인수로 호출해서는 안 됩니다. 그렇게 하면 공격자가 의사 난수 발생기(PRNG)의 시드 생성에 사용되는 값을 제어할 수 있게 되므로 의사 난수 발생기를 호출하여 생성되는 값(대개 정수)의 시퀀스를 예측할 수 있게 됩니다.

Explanation
Random.setSeed()는 감염된 정수 인수로 호출해서는 안 됩니다. 그렇게 하면 공격자가 의사 난수 발생기(PRNG)의 시드 생성에 사용되는 값을 제어할 수 있게 되므로 Random.nextInt(), Random.nextShort(), Random.nextLong()을 호출하여 생성되거나, Random.nextBoolean()에서 반환되거나, Random.nextBytes(byte[])에 설정되는 값(주로, 정수)의 시퀀스를 예측할 수 있게 됩니다.

Abstract
HTML sanitizer 정책을 정의하기 위한 사용자 제어 또는 신뢰할 수 없는 데이터 사용을 통해 공격자는 정화 요구 사항을 피하고 Cross-Site Scripting(XSS) 공격을 실행할 수 있습니다.
Explanation
포괄적 용어 “입력 처리”는 입력 데이터의 확인, 정화, 필터링 및 인코딩/디코딩과 같은 기능을 설명합니다. Cross-Site Scripting, SQL injection 및 process control 취약점은 모두 입력 처리가 잘못되거나 없는 것에서 기인합니다. 수용 가능한 형태로 입력 변환을 수반하는 입력 정화는 일반적으로 입력 확인에 추가하여 구현됩니다. HTML 정화는 안전한 태그, 속성 및 요소만 허용하도록 사용자 입력을 정화하고 정리하는 것을 나타냅니다.
완벽한 HTML 정화 정책 구현은 어렵습니다. 성공적인 구현의 핵심은 데이터가 사용될 컨텍스트를 이해하는 것입니다. 각 컨텍스트에는 고유의 취약점이 있으며 하나의 크기가 모두에 맞지는 않습니다. HTML sanitizer(예: OWASP HTML sanitizer)를 사용하여 웹 응용 프로그램의 XSS 취약점을 방지하는 것이 현명하며 부적절한 구현은 보안에 대한 잘못된 인식으로 이어질 수 있습니다.
예제 1: 다음 Java 코드는 HTML sanitizer 정책 구축에서 사용자 제어 입력 변수 elements를 사용합니다.


...
String elements = prop.getProperty("AllowedElements");
...
public static final PolicyFactory POLICY_DEFINITION = new HtmlPolicyBuilder()
.allowElements(elements)
.toFactory();

....


악의적인 사용자는 elements를 공급하여 <script> 등의 위험한 요소를 HTML sanitizer 정책에서 수용하도록 할 수 있습니다.

Abstract
응용 프로그램은 사용자 지정 SSL 인터페이스를 구현합니다.
Explanation
SSL 표준은 클라이언트 측에서 SSL 확인 검사를 수행하는 방법에 대한 지침을 제공합니다. 그러나 이러한 구현은 표준에 포함되어 있지 않습니다. 따라서 확인 로직의 구현은 응용 프로그램 개발자의 몫입니다.

조사에 따르면 SSL 표준 사양의 복잡성과 개방성은 결점 없는 사용자 지정 SSL 구현을 어렵게 만드는 몇 가지 문제를 야기합니다. 사용자 지정 SSL 구현을 사용하는 대부분의 Android 응용 프로그램은 보안 통신 채널을 제공하지 못하는 결점이 있으며 이로 인해 응용 프로그램이 MITM(Man-In-The-Middle) 공격에 취약해집니다.

Abstract
이 메서드는 SSL 확인 검사에 실패합니다.
Explanation
InetAddress를 함수 매개 변수로 받아들이는 createSocket()에 대한 호출은 호스트 이름 확인을 수행하지 않습니다.

마찬가지로, getInsecure()에 대한 호출은 모든 SSL 검사가 비활성화된 SSL 소켓 팩토리를 반환합니다.

둘 다 모두 응용 프로그램을 MITM(Man-In-The-Middle) 공격에 취약하게 만듭니다.

예를 들어 응용 프로그램은 https://safesecureserver.banking.com 연결을 시도할 때 https://hackedserver.banking.com에 발급된 인증서를 즉시 수락합니다. 그러면 이제 응용 프로그램은 해킹당한 서버에 대한 손상된 SSL 연결에서 민감한 사용자 정보를 누출할 가능성이 있습니다.

Abstract
응용 프로그램은 인증서 체인 검증에 적합하지 않은 메서드를 호출합니다.
Explanation
응용 프로그램은 서버의 최종-엔터티 인증서와 시스템에서 신뢰하는 CA(인증 기관) 인증서 간의 올바른 신뢰 경로의 일부가 아닌 항목을 제거하지 않고 서버에서 반환하는 전체 인증서 목록을 반환하는 메서드를 호출합니다.

공격자가 손상된 CA의 개인 키에 대한 액세스를 소유한 경우 SSL/TLS 연결을 가로채고 서버에서 제공한 인증서를 수정할 수 있습니다. 이 시나리오에서는 공격자가 서버의 최종-엔터티 인증서에서 손상된 루트 CA로의 올바른 신뢰 경로를 생성하여 클라이언트가 인증서를 신뢰하고 서버에서 제공한 나머지 원래 인증서를 추가하게 만들 수 있습니다.

클라이언트가 인증서 고정을 사용하는 경우 "고정된" 인증서가 서버에서 제공한 항목 중 하나임을 확인하게 됩니다. 클라이언트가 올바른 신뢰 경로의 일부가 아닌 항목을 제거하지 않고 서버에서 제공한 모든 인증서를 반환하는 메서드를 사용하는 경우 유효한 손상된 개인 키를 가진 공격자가 웹 서버가 제공한 원래 인증서와 해당 손상된 CA에 대한 유효한 신뢰 경로를 제공할 수 있습니다. 해당 시나리오에서는 공격자가 인증서 고정 확인을 우회할 수 있습니다.

Abstract
SSL/TLS 연결은 기본 사전 로드된 시스템 CA(인증 기관)를 사용하여 생성되며 이로 인해 공격자가 손상된 루트 CA로 서명된 인증서를 사용하여 MiTM(Man-in-The-Middle: 메시지 가로채기) 공격을 수행하여 암호화된 통신을 가로챌 수 있습니다.
Explanation
PKI(공용 키 인프라)는 신뢰할 수 있는 CA(인증 기관)를 기반으로 하지만 손상된 인증 기관 증가는 해당 루트 인증서를 더 이상 신뢰할 수 없으며 그렇기 때문에 이 CA에서 서명한 인증서도 신뢰할 수 없음을 의미합니다. 이러한 손상된 인증서를 소유한 공격자는 이러한 CA를 신뢰하는 모든 SSL/TLS 트래픽을 가로챌 수 있습니다.

인증 기관 서명은 임의의 네트워크 끝점에 연결하며 이러한 끝점에 대한 SSL/TLS 인증서를 서명하는 CA에 대한 고급 지식이 없는 브라우저와 같은 범용 네트워크 통신 도구에 필요합니다. 제한된 수의 백엔드 서버에 연결하는 모바일 응용 프로그램은 이러한 서버가 해당 인증서 서명에 사용하고 응용 프로그램에서 이러한 인증서/공용 키를 "고정"하여 응용 프로그램이 예상하는 인증서로 신뢰 수준을 줄일 수 있는 신뢰할 수 있는 CA 최종 후보 목록 인지를 활용할 수 있습니다.

예제 1: 다음 예제는 기본 사전 로드된 시스템 CA를 사용하여 SSL/TLS 연결을 설정합니다.

URL url = new URL("https://myserver.org");
URLConnection urlConnection = url.openConnection();
InputStream in = urlConnection.getInputStream();
URLConnection에 사용되는 기본 SSLSocketFactory는 변경되지 않았기 때문에 Android 기본 키 저장소에 있는 모든 CA를 신뢰하는 기본 항목을 사용합니다.

Abstract
SSL/TLS 연결은 기본 사전 로드된 시스템 CA(인증 기관)를 사용하여 생성되며 이로 인해 공격자가 손상된 루트 CA로 서명된 인증서를 사용하여 MiTM(Man-in-The-Middle: 메시지 가로채기) 공격을 수행하여 암호화된 통신을 가로챌 수 있습니다.
Explanation
PKI(공용 키 인프라)는 신뢰할 수 있는 CA(인증 기관)를 기반으로 하지만 손상된 인증 기관 증가는 해당 루트 인증서를 더 이상 신뢰할 수 없으며 그렇기 때문에 이 CA에서 서명한 인증서도 신뢰할 수 없음을 의미합니다. 이러한 손상된 인증서를 소유한 공격자는 이러한 CA를 신뢰하는 모든 SSL/TLS 트래픽을 가로챌 수 있습니다.

인증 기관 서명은 임의의 네트워크 끝점에 연결하며 이러한 끝점에 대한 SSL/TLS 인증서를 서명하는 CA에 대한 고급 지식이 없는 브라우저와 같은 범용 네트워크 통신 도구에 필요합니다. 제한된 수의 백엔드 서버에 연결하는 모바일 응용 프로그램은 이러한 서버가 해당 인증서 서명에 사용하고 응용 프로그램에서 이러한 인증서/공용 키를 "고정"하여 응용 프로그램이 예상하는 인증서로 신뢰 수준을 줄일 수 있는 신뢰할 수 있는 CA 최종 후보 목록 인지를 활용할 수 있습니다.

예제 1: 다음 예제는 기본 사전 로드된 시스템 CA를 사용하여 SSL/TLS 연결을 설정합니다.

val url = URL("https://myserver.org")
val data = url.readBytes()
URLConnection에 사용되는 기본 SSLSocketFactory는 변경되지 않았기 때문에 Android 기본 키 저장소에 있는 모든 CA를 신뢰하는 기본 항목을 사용합니다.

Abstract
SSL/TLS 연결은 기본 사전 로드된 시스템 CA(인증 기관)를 사용하여 생성되며 이로 인해 공격자가 손상된 루트 CA로 서명된 인증서를 사용하여 MiTM(Man-in-The-Middle: 메시지 가로채기) 공격을 수행하여 암호화된 통신을 가로챌 수 있습니다.
Explanation
PKI(공용 키 인프라)는 신뢰할 수 있는 CA(인증 기관)를 기반으로 하지만 손상된 인증 기관 증가는 해당 루트 인증서를 더 이상 신뢰할 수 없으며 그렇기 때문에 이 CA에서 서명한 인증서도 신뢰할 수 없음을 의미합니다. 이러한 손상된 인증서를 소유한 공격자는 이러한 CA를 신뢰하는 모든 SSL/TLS 트래픽을 가로챌 수 있습니다.

인증 기관 서명은 임의의 네트워크 끝점에 연결하며 이러한 끝점에 대한 SSL/TLS 인증서를 서명하는 CA에 대한 고급 지식이 없는 브라우저와 같은 범용 네트워크 통신 도구에 필요합니다. 제한된 수의 백엔드 서버에 연결하는 모바일 응용 프로그램은 이러한 서버가 해당 인증서 서명에 사용하고 응용 프로그램에서 이러한 인증서/공용 키를 "고정"하여 응용 프로그램이 예상하는 인증서로 신뢰 수준을 줄일 수 있는 신뢰할 수 있는 CA 최종 후보 목록 인지를 활용할 수 있습니다.

예제 1: 다음 예제는 기본 사전 로드된 시스템 CA를 사용하여 SSL/TLS 연결을 설정합니다.

NSString* requestString = @"https://myserver.org";
NSURL* requestUrl = [NSURL URLWithString:requestString];
NSURLRequest* request = [NSURLRequest requestWithURL:requestUrl
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
timeoutInterval:10.0f];
NSURLConnection* connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];


인증서 확인을 처리하도록 정의된 NSURLConnectionDelegate 메서드가 없기 때문에 iOS 기본 키 저장소에 있는 모든 CA를 신뢰하는 시스템을 사용합니다.

SSL/TLS 연결은 기본 사전 로드된 시스템 CA(인증 기관)를 사용하여 생성되며 이로 인해 공격자가 손상된 루트 CA로 서명된 인증서를 사용하여 MiTM(Man-in-The-Middle: 메시지 가로채기) 공격을 수행하여 암호화된 통신을 가로챌 수 있습니다.
Explanation
PKI(공용 키 인프라)는 신뢰할 수 있는 CA(인증 기관)를 기반으로 하지만 손상된 인증 기관 증가는 해당 루트 인증서를 더 이상 신뢰할 수 없으며 그렇기 때문에 이 CA에서 서명한 인증서도 신뢰할 수 없음을 의미합니다. 이러한 손상된 인증서를 소유한 공격자는 이러한 CA를 신뢰하는 모든 SSL/TLS 트래픽을 가로챌 수 있습니다.

인증 기관 서명은 임의의 네트워크 끝점에 연결하며 이러한 끝점에 대한 SSL/TLS 인증서를 서명하는 CA에 대한 고급 지식이 없는 브라우저와 같은 범용 네트워크 통신 도구에 필요합니다. 제한된 수의 백엔드 서버에 연결하는 모바일 응용 프로그램은 이러한 서버가 해당 인증서 서명에 사용하고 응용 프로그램에서 이러한 인증서/공용 키를 "고정"하여 응용 프로그램이 예상하는 인증서로 신뢰 수준을 줄일 수 있는 신뢰할 수 있는 CA 최종 후보 목록 인지를 활용할 수 있습니다.

예제 1: 다음 예제는 기본 사전 로드된 시스템 CA를 사용하여 SSL/TLS 연결을 설정합니다.

let requestString = NSURL(string: "https://myserver.org")
let requestUrl : NSURL = NSURL(string:requestString)!;
let request : NSURLRequest = NSURLRequest(URL:requestUrl);
let connection : NSURLConnection = NSURLConnection(request:request, delegate:self)!;


인증서 확인을 처리하도록 정의된 NSURLConnectionDelegate 메서드가 없기 때문에 iOS 기본 키 저장소에 있는 모든 CA를 신뢰하는 시스템을 사용합니다.

Abstract
이로 인해 SSL 연결을 설정할 때 서버 ID 확인이 비활성화됩니다.
Explanation
SSL 연결을 사용하는 일부 라이브러리에서는 서버 인증서가 기본적으로 확인되지 않습니다. 이것은 모든 인증서를 신뢰하는 것과 같습니다. 다른 경우에는 의도에 관계없이 명시적으로 비활성화할 수 있습니다.

예제 1: 이 응용 프로그램은 항상 인증서 체인이 올바른지 확인하여 모든 인증서를 신뢰합니다.


...
private bool CertificateCheck(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
...
return true;
}
...
HttpWebRequest webRequest = (HttpWebRequest) WebRequest.Create("https://www.myTrustedSite.com");
webRequest.ServerCertificateValidationCallback = CertificateCheck;
WebResponse response = webRequest.GetResponse();
...


"https://www.myTrustedSite.com"에 연결하려고 하면 이 응용 프로그램은 "hackedserver.com"에 발급된 인증서를 즉시 수락합니다. 그러면 이제 응용 프로그램은 해킹당한 서버에 대한 손상된 SSL 연결에서 민감한 사용자 정보를 누출할 가능성이 있습니다.

Abstract
이로 인해 SSL 연결을 설정할 때 서버 ID 확인이 비활성화됩니다.
Explanation
SSL 연결을 사용하는 일부 라이브러리에서는 서버 인증서 확인을 비활성화할 수 있습니다. 이것은 모든 인증서를 신뢰하는 것과 같습니다.

예제 1: 이 응용 프로그램에서는 인증서 확인을 명시적으로 비활성화합니다.


...
SSL_CTX_set_verify(ctx, SSL_VERIFY_NONE, verify_callback);
...


유효한 호스트에 연결하려고 하면 이 응용 프로그램은 "hackedserver.com"에 발급된 인증서를 즉시 수락합니다. 그러면 이제 응용 프로그램은 해킹당한 서버에 대한 손상된 SSL 연결에서 민감한 사용자 정보를 누출할 가능성이 있습니다.

Abstract
이로 인해 SSL 연결을 설정할 때 서버 ID 확인이 비활성화됩니다.
Explanation
SSL 연결을 사용하는 일부 라이브러리에서는 서버 인증서가 기본적으로 확인되지 않습니다. 이것은 모든 인증서를 신뢰하는 것과 같습니다.

예제 1: 이 응용 프로그램은 서버 인증서를 명시적으로 확인하지 않습니다.


...
Email email = new SimpleEmail();
email.setHostName("smtp.servermail.com");
email.setSmtpPort(465);
email.setAuthenticator(new DefaultAuthenticator(username, password));
email.setSSLOnConnect(true);
email.setFrom("user@gmail.com");
email.setSubject("TestMail");
email.setMsg("This is a test mail ... :-)");
email.addTo("foo@bar.com");
email.send();
...


이 응용 프로그램은 smtp.mailserver.com:465 연결을 시도할 때 "hackedserver.com"에 발급된 인증서를 즉시 수락합니다. 그러면 이제 응용 프로그램은 해킹당한 서버에 대한 손상된 SSL 연결에서 민감한 사용자 정보를 누출할 가능성이 있습니다.

Abstract
이로 인해 SSL 연결을 설정할 때 서버 ID 확인이 비활성화됩니다.
Explanation
SSL 연결을 사용하는 일부 라이브러리에서는 서버 인증서가 기본적으로 확인되지 않습니다. 이것은 모든 인증서를 신뢰하는 것과 같습니다.

예제 1: 이 서버에서 클라이언트 연결을 확인하기 위한 잘못된 시도를 수행합니다.


...
var options = {
key : fs.readFileSync('my-server-key.pem'),
cert : fs.readFileSync('server-cert.pem'),
requestCert: true,
...
}
https.createServer(options);
...


https.Server 개체가 생성될 때 requestCert 설정이 true로 지정되지만 rejectUnauthorized가 설정되지 않습니다. 이는 false에 대한 기본값입니다. 이렇게 되면 SSL을 통해 클라이언트를 확인하기 위해 서버를 생성해도, 제공된 CA 목록으로 인증서가 인증되지 않은 경우에도 연결이 수락되지 않습니다.

예제 2: 이 응용 프로그램에서 SSL을 통해 서버에 연결하려고 합니다.


var tls = require('tls');
...
tls.connect({
host: 'https://www.hackersite.com',
port: '443',
...
rejectUnauthorized: false,
...
});


이 예제에서는 rejectUnauthorized가 false로 설정되었으므로 인증되지 않은 인증서가 수락되고 확인되지 않은 서버로의 보안 연결도 생성됩니다. 그러면 이제 응용 프로그램은 해킹당한 서버에 대한 손상된 SSL 연결에서 민감한 사용자 정보를 누출할 가능성이 있습니다.

Abstract
이로 인해 SSL 연결을 설정할 때 서버 ID 확인이 비활성화됩니다.
Explanation
SSL 연결을 호출하는 일부 라이브러리에서는 서버 인증서를 기본적으로 확인하지 않습니다(또는 확인하지 않도록 명시적으로 구성할 수도 있음). 이것은 모든 인증서를 신뢰하는 것과 같습니다.

예제 1: 이 코드에서는 모든 HTTPS 인증서를 수락하도록 NSURLConnectionDelegate를 구성합니다.


implementation NSURLRequest (IgnoreSSL)

+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host
{
return YES;
}

@end
Example 1NSURLRequest 구현을 사용하여 SSL을 통해 보안이 유지되는 서버에 연결하려고 하면 요청된 서버의 인증서가 자체 서명된 인증서인 경우 확인되지 않으므로 경고나 오류가 생성되지 않습니다. 따라서 응용 프로그램이 이제 손상된 SSL 연결을 통해 민감한 사용자 정보를 누출하게 될 수도 있습니다.

Abstract
이로 인해 SSL 연결을 설정할 때 서버 ID 확인이 비활성화됩니다.
Explanation
SSL 연결을 사용하는 일부 라이브러리에서는 서버 인증서 확인을 비활성화할 수 있습니다. 이것은 모든 인증서를 신뢰하는 것과 같습니다.

예제 1: 이 응용 프로그램에서는 인증서 확인을 명시적으로 비활성화합니다.


require 'openssl'
...
ctx = OpenSSL::SSL::SSLContext.new
ctx.verify_mode=OpenSSL::SSL::VERIFY_NONE
...


유효한 호스트에 연결하려고 하면 이 응용 프로그램은 "hackedserver.com"에 발급된 인증서를 즉시 수락합니다. 그러면 이제 응용 프로그램은 해킹당한 서버에 대한 손상된 SSL 연결에서 민감한 사용자 정보를 누출할 가능성이 있습니다.

desc.structural.ruby.insecure_ssl_server_identity_verification_disabled
Abstract
이로 인해 SSL 연결을 설정할 때 서버 ID 확인이 비활성화됩니다.
Explanation
SSL 연결을 호출하는 일부 라이브러리에서는 서버 인증서를 기본적으로 확인하지 않습니다(또는 확인하지 않도록 명시적으로 구성할 수도 있음). 이것은 모든 인증서를 신뢰하는 것과 같습니다.

예제 1: 이 코드에서는 모든 HTTPS 인증서를 수락하도록 NSURLConnectionDelegate를 구성합니다.


class Delegate: NSObject, NSURLConnectionDelegate {

...

func connection(connection: NSURLConnection, canAuthenticateAgainstProtectionSpace protectionSpace: NSURLProtectionSpace?) -> Bool {
return protectionSpace?.authenticationMethod == NSURLAuthenticationMethodServerTrust
}

func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge) {
challenge.sender?.useCredential(NSURLCredential(forTrust: challenge.protectionSpace.serverTrust!), forAuthenticationChallenge: challenge)
challenge.sender?.continueWithoutCredentialForAuthenticationChallenge(challenge)
}
}
Example 1NSURLConnectionDelegate 구현을 사용하여 SSL을 통해 보안이 유지되는 서버에 연결하려고 하면 요청된 서버의 인증서가 자체 서명된 인증서인 경우 확인되지 않으므로 경고나 오류가 생성되지 않습니다. 따라서 응용 프로그램이 이제 손상된 SSL 연결을 통해 민감한 사용자 정보를 누출하게 될 수도 있습니다.

예제 2:NSURLSession 클래스에서 SSL/TLS 체인 검증은 응용 프로그램의 인증 대리자 메서드에 의해 처리되지만, 사용자(또는 응용 프로그램)를 서버에 인증하기 위해 자격 증명을 제공하는 대신 응용 프로그램은 SSL/TLS 핸드셰이크 도중 서버가 제공하는 자격 증명을 확인한 다음 해당 자격 증명의 수락/거부 여부를 URL 로딩 시스템에 알립니다. 다음 코드는 수신한 챌린지의 proposedCredential을 세션에 대한 자격 증명으로 다시 전달함으로써 서버 확인을 실제로 우회하는 NSURLSessionDelgate를 보여 줍니다.


class MySessionDelegate : NSObject, NSURLSessionDelegate {
...
func URLSession(session: NSURLSession, didReceiveChallenge challenge: NSURLAuthenticationChallenge, completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential?) -> Void) {
...
completionHandler(NSURLSessionAuthChallengeDisposition.UseCredential, challenge.proposedCredential)
...
}
...
}

Abstract
이 프로그램은 Android의 백업 서비스를 사용하여 영구 응용 프로그램 데이터를 원격 클라우드 스토리지에 저장합니다.
Explanation
Android의 백업 서비스를 사용하면 응용 프로그램이 원격 클라우드 스토리지에 영구 데이터를 저장하여 향후에 응용 프로그램 데이터의 복원 지점을 제공할 수 있습니다.

Android 응용 프로그램을 이 백업 서비스로 구성하려면 allowBackup 속성을 true(기본값)로 설정하고 <application> 태그에서 backupAgent 속성을 정의하면 됩니다.

그러나 Android에서는 클라우드 스토리지 및 전송이 장치마다 다르기 때문에 백업을 사용하는 동안 데이터 보안이 보장되지 않습니다.

Abstract
프로그램은 Android 장치의 외부 저장소에 데이터를 기록합니다.
Explanation
외부 저장소에 저장한 파일은 누구나 읽을 수 있으며 USB 대용량 저장소로 컴퓨터의 파일을 전송할 때 사용자가 수정할 수 있습니다. 또한, 외부 저장소 카드에 있는 파일은 파일을 작성한 응용 프로그램을 제거한 후에도 그대로 유지됩니다. 이러한 제약으로 인해 저장소에 작성된 민감한 정보가 손상되거나 공격자가 프로그램이 의존하는 외부 파일을 수정하여 악성 데이터를 프로그램에 삽입할 수도 있습니다.

예제 1: 다음 코드에서, Environment.getExternalStorageDirectory()는 Android 장치의 외부 저장소에 대한 참조를 반환합니다.

 private void WriteToFile(String what_to_write) {
try{
File root = Environment.getExternalStorageDirectory();
if(root.canWrite()) {
File dir = new File(root + "write_to_the_SDcard");
File datafile = new File(dir, number + ".extension");
FileWriter datawriter = new FileWriter(datafile);
BufferedWriter out = new BufferedWriter(datawriter);
out.write(what_to_write);
out.close();
}
}
}

Abstract
응용 프로그램은 Android 장치의 모든 응용 프로그램에서 데이터에 접근할 수 있도록 합니다.
Explanation
MODE_WORLD_READBLE 또는 MODE_WORLD_WRITEABLE을 사용하여 Android 내부 저장소에 저장된 데이터를 장치의 모든 응용 프로그램에서 액세스할 수 있습니다. 이로 인해 데이터가 손상되지 않도록 보호되지 않을 뿐 아니라 민감한 정보의 경우 사용자 개인 정보 유지 및 보안 문제를 위반합니다.

Abstract
식별된 메서드는 안전하지 않은 공유 저장소에 HTTP(S) 응답 캐시를 설정합니다.
Explanation
HTTP(S) 응답에 세션 쿠키 및 API 토큰과 같은 민감한 데이터가 포함될 수 있습니다. URL 로딩 시스템은 성능상의 이유로 모든 HTTP(S) 응답을 캐시하고 암호화하지 않은 상태로 안전하지 않은 공유 저장소에 저장합니다.

예제 1: 다음 코드는 공유 저장소 공간에 HTTP(S) 응답 캐시를 설치합니다.


protected void onCreate(Bundle savedInstanceState) {
...

try {
File httpCacheDir = new File(context.getExternalCacheDir(), "http");
long httpCacheSize = 10 * 1024 * 1024; // 10 MiB
HttpResponseCache.install(httpCacheDir, httpCacheSize);
} catch (IOException e) {
Log.i(TAG, "HTTP response cache installation failed:" + e);
}
}

protected void onStop() {
...

HttpResponseCache cache = HttpResponseCache.getInstalled();
if (cache != null) {
cache.flush();
}
}

Abstract
식별된 메서드는 암호화되지 않은 데이터베이스에 대한 연결을 설정합니다.
Explanation
응용 프로그램 파일은 루팅된 장치의 다른 응용 프로그램이나 암호화되지 않은 백업에서 액세스할 수 있습니다. 사용자가 자신의 장치를 탈옥하거나 암호화되지 않은 백업을 수행하기로 결정할 수 있기 때문에, 민감한 데이터가 포함된 데이터베이스는 암호화하는 것이 좋습니다.

예제 1: 다음 코드는 암호화되지 않은 Realm 데이터베이스에 대한 연결을 설정합니다.


Realm realm = Realm.getDefaultInstance();

Abstract
식별된 메서드는 암호화되지 않은 데이터베이스에 대한 연결을 설정합니다.
Explanation
응용 프로그램 파일은 루팅된 장치의 다른 응용 프로그램이나 암호화되지 않은 백업에서 액세스할 수 있습니다. 사용자가 자신의 장치를 탈옥하거나 암호화되지 않은 백업을 수행하기로 결정할 수 있기 때문에, 민감한 데이터가 포함된 데이터베이스는 암호화하는 것이 좋습니다.

예제 1: 다음 코드는 암호화되지 않은 Realm 데이터베이스에 대한 연결을 설정합니다.


RLMRealmConfiguration *config = [RLMRealmConfiguration defaultConfiguration];
RLMRealm *realm = [RLMRealm realmWithConfiguration:config error:nil];

Abstract
응용 프로그램은 AWS S3 버킷 또는 개체에 대한 전체 익명 액세스 권한을 부여합니다.
Explanation
버킷이나 개체에 대한 전체 익명 액세스 권한을 부여하면 공격자가 콘텐트를 읽거나 악성 콘텐트로 바꿀 수 있습니다.

예제 1: 다음 코드는 foo 버킷에 대한 전체 익명 액세스 권한을 부여하는 Access Control Policy를 설정합니다.


GetBucketAclRequest bucketAclReq = GetBucketAclRequest.builder().bucket("foo").build();
GetBucketAclResponse getAclRes = s3.getBucketAcl(bucketAclReq);
List<Grant> grants = getAclRes.grants();

Grantee allusers = Grantee.builder().uri("http://acs.amazonaws.com/groups/global/AllUsers").build();
Permission fc_permission = Permission.fromValue("FullControl");
Grant grant = Grant.builder().grantee(allusers).permission(fc_permission).build();
grants.add(grant);

AccessControlPolicy acl = AccessControlPolicy.builder().grants(grants).build();

Abstract
응용 프로그램은 AWS S3 버킷 또는 개체의 ACP(액세스 제어 정책)를 읽을 수 있는 익명 권한을 부여합니다.
Explanation
버킷이나 개체의 ACP(액세스 제어 정책)를 읽을 수 있는 익명 권한을 부여하면 공격자는 검색하거나 덮어쓸 수 있는 개체를 찾을 수 있습니다.

예제 1: 다음 코드는 foo 버킷에 대한 익명 ACP 읽기 권한을 부여하는 Access Control Policy를 설정합니다.


GetBucketAclRequest bucketAclReq = GetBucketAclRequest.builder().bucket("foo").build();
GetBucketAclResponse getAclRes = s3.getBucketAcl(bucketAclReq);
List<Grant> grants = getAclRes.grants();

Grantee allusers = Grantee.builder().uri("http://acs.amazonaws.com/groups/global/AllUsers").build();
Permission fc_permission = Permission.fromValue("READ_ACP");
Grant grant = Grant.builder().grantee(allusers).permission(fc_permission).build();
grants.add(grant);

AccessControlPolicy acl = AccessControlPolicy.builder().grants(grants).build();

Abstract
응용 프로그램은 AWS S3 버킷 또는 개체에 대한 익명 읽기 권한을 부여합니다.
Explanation
버킷이나 개체에 대한 익명 읽기 권한을 부여하면 공격자가 콘텐트를 읽을 수 있습니다.

예제 1: 다음 코드는 foo 버킷에 대한 익명 읽기 권한을 부여하는 Access Control Policy를 설정합니다.


GetBucketAclRequest bucketAclReq = GetBucketAclRequest.builder().bucket("foo").build();
GetBucketAclResponse getAclRes = s3.getBucketAcl(bucketAclReq);
List<Grant> grants = getAclRes.grants();

Grantee allusers = Grantee.builder().uri("http://acs.amazonaws.com/groups/global/AllUsers").build();
Permission fc_permission = Permission.fromValue("Read");
Grant grant = Grant.builder().grantee(allusers).permission(fc_permission).build();
grants.add(grant);

AccessControlPolicy acl = AccessControlPolicy.builder().grants(grants).build();
