Abstract
응용 프로그램이 클래스 또는 메서드 수준에서 [AllowAnonymous] 속성을 사용하여 [Authorize] 속성이 부여한 권한 부여를 우회합니다.
Explanation
ASP.NET Core를 사용하면 [Authorize] 속성을 클래스 또는 메서드에 추가하여 응용 프로그램 작업에 권한 부여가 필요하도록 만들 수 있습니다. 또한 [AllowAnonymous] 속성을 추가하여 응용 프로그램 클래스 또는 메서드의 지정된 권한 부여 요구 사항을 우회할 수 있습니다. 둘 다 지정하면 [AllowAnonymous] 속성이 우선적으로 적용되고 [Authorize] 속성을 우회합니다. 이로 인해 공격자가 민감한 데이터 및 작업에 임의로 익명으로 액세스할 수 있습니다.

예제 1: 다음 예제는 메서드에 설정된 [Authorize] 속성을 재정의하는 클래스 수준의 [AllowAnonymous] 속성을 보여줍니다. secretAction() 메서드는 [Authorize] 속성이 있음에도 불구하고 권한 부여가 필요하지 않습니다.


...
[AllowAnonymous]
public class Authorization_Test
{
[Authorize]
public IActionResult secretAction()
{

}
}
...
예제 2: 다음 예제는 하위 클래스의 메서드에 설정된 [Authorize] 속성을 재정의하는 슈퍼클래스 클래스 수준의 [AllowAnonymous] 속성을 보여줍니다. 상속된 클래스 Inherit_AA[AllowAnonymous] 속성으로 인해 secretAction() 메서드는[Authorize] 속성을 지정함에도 불구하고 권한 부여가 필요하지 않습니다.


...
[AllowAnonymous]
public abstract class Inherit_AA
{

}

public class Authorization_Test:Inherit_AA
{
[Authorize]
public IActionResult secretAction()
{

}
}
...
예제 3: 다음은 상속이 있는 메서드 수준에서 [Authorize] 속성을 재정의하는 [AllowAnonymous] 속성을 보여줍니다. 상속된 메서드 secretAction()[AllowAnonymous] 속성으로 인해 secretAction() 메서드는[Authorize] 속성을 지정함에도 불구하고 권한 부여가 필요하지 않습니다.

Abstract
사용자 권한을 확인하지 않고 SOQL 문을 실행하면 공격자가 권한이 없는 항목을 수정할 수 있습니다.
Explanation
Access control 취약점은 공격자가 인증된 사용자에게만 제한된 리소스에 액세스할 수 있을 때 발생합니다.

기본적으로, SObjects 및 SObject 필드가 사용되는 경우 Visualforce 응용 프로그램은 개체 수준 보안(CRUD) 및 필드 수준 보안(FLS)을 자동으로 적용합니다. 하지만 개체 및 필드가 일반 데이터 유형으로 참조되는 경우, 이런 메커니즘은 적용되지 않으며 access control 검사는 프로그래밍 방식으로 구현되어야 합니다.

예제 1: 다음 코드 예제에서, 필드는 사용자 지정 세터 메서드를 사용하여 업데이트되므로, 권한 부여 검사가 필요합니다.

<apex:page controller="accessControl">
<apex:pageBlock >
<apex:pageBlockSection >
<apex:outputText value="Survey Name: "/>
<apex:inputText value="{!surveyName}"/>
</apex:pageBlockSection>
<apex:pageBlockSection >
<apex:outputText value="New Name: "/>
<apex:inputText value="{!newSurveyName}"/>
</apex:pageBlockSection>
<apex:pageBlockSection >
<apex:commandButton value="Update" action="{!updateName}"/>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:page>

public String surveyName { get; set; }
public String newSurveyName { get; set; }
public PageReference updateName() {
Survey__c s = [SELECT Name FROM Survey__c WHERE Name=:surveyName];

s.Name = newSurveyName;
update s;

PageReference page = ApexPages.currentPage();
page.setRedirect(true);
return page;
}

Abstract
응용 프로그램은 공격자가 AWS S3 버킷 또는 개체의 ACP(액세스 제어 정책)를 조작할 수 있도록 허용합니다.
Explanation
응용 프로그램은 공격자가 AWS S3 버킷 또는 개체에 대해 부여된 권한을 조작할 수 있도록 허용합니다. 이를 통해 공격자는 콘텐트를 읽거나 임의의 파일을 쓸 수 있는 약한 정책을 설정할 수 있습니다.

예제 1: 다음 코드는 사용자가 지정한 액세스 제어 정책을 사용하여 새 버킷을 생성합니다.



String canned_acl = request.getParameter("acl");

CreateBucketRequest createBucketRequest = CreateBucketRequest.builder()
.bucket("foo")
.acl(canned_acl)
.createBucketConfiguration(CreateBucketConfiguration.builder().locationConstraint(region.id()).build())
.build();



응용 프로그램이 제한된 집합에서 acl 매개 변수를 선택한다고 해도 공격자는 이를 public-read-write로 설정하고 버킷에 대한 전체 익명 액세스 권한을 부여할 수 있습니다.

Abstract
적절한 access control 없이 사용자가 제어하는 항목 이름을 가진 SimpleDB 데이터베이스에 접근하면 공격자가 허가 받지 않은 레코드를 볼 수 있습니다.
Explanation
데이터베이스 Access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 데이터는 SimpleDB 액세스 요청 시 항목 이름을 지정하는 데 사용됩니다.
예제 1: 다음 코드는 해당 트랜잭션의 날짜에 따라 이름이 지정된 송장의 데이터베이스에서 작동합니다. 프로그램은 먼저 고객을 인증하고 그 이후에 고객이 목록에서 이전의 송장을 선택하게 합니다.


...
String selectedInvoice = request.getParameter("invoiceDate");
...
AmazonSimpleDBClient sdbc = new AmazonSimpleDBClient(appAWSCredentials);
GetAttributesResult sdbResult = sdbc.getAttributes(new GetAttributesRequest("invoices", selectedInvoice));
...
Example 1의 코드는 현재 사용자의 송장 목록을 생성하지만 공격자는 이 동작을 무시하고 원하는 송장을 요청할 수 있습니다. 이 예제의 코드가 사용자가 요청한 송장에 접근할 수 있는 권한이 있는지 확인하지 않기 때문에 현재 사용자의 송장이 아닌 송장도 모두 표시합니다.

Abstract
적절한 access control 없이 사용자가 제어하는 기본 키를 포함하는 SQLite 문을 실행하면 공격자가 허가 받지 않은 레코드를 볼 수 있습니다.
Explanation
다음과 같은 경우 SQLite 쿼리에서 access control 오류가 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 데이터는 SQLite 쿼리에서 기본 키의 값을 지정하는 데 사용됩니다.
예제 1: 다음 코드는 메타 문자를 이스케이프 처리하고 query string injection 취약점을 예방하는, 매개 변수가 있는 구문을 사용하여 사용자가 지정한 ID와 일치하는 송장을 검색하는 SQLite 쿼리를 생성하여 실행합니다.


...
id = this.getIntent().getExtras().getInt("id");
cursor = db.query(Uri.parse(invoices), columns, "id = ? ", {id}, null, null, null);
...


문제는 개발자가 id의 가능한 모든 값을 고려할 수 없다는 점입니다. 쿼리에서 현재 사용자의 송장 ID 목록을 생성하지만 공격자는 이 동작을 무시하고 원하는 송장을 요청할 수 있습니다. 이 예제의 코드가 사용자가 요청한 송장에 접근할 수 있는 권한이 있는지 확인하지 않기 때문에 현재 사용자의 송장이 아닌 송장도 모두 표시합니다.

Abstract
적절한 access control 없이 사용자가 제어하는 값을 포함하는 LDAP 문을 실행하면 공격자가 허가 받지 않은 레코드에 접근할 수 있습니다.
Explanation
사실상 authentication 없이 익명의 바인딩에서 LDAP 쿼리를 실행하면 공격자가 빈약하게 구성된 LDAP 환경을 남용할 수 있습니다.

예제 1: 다음 코드는 익명 바운딩을 사용하여 DirectoryEntry de를 생성합니다.


...
de = new DirectoryEntry("LDAP://ad.example.com:389/ou=People,dc=example,dc=com");
...
de에 대해 실행된 모든 LDAP 쿼리는 authentication 및 access control 없이 수행됩니다. 공격자는 디렉터리의 액세스 제어 메커니즘으로 보호되는 레코드에 대한 액세스를 얻기 위해 예기치 못한 방법으로 이러한 쿼리 중 하나를 조작할 수도 있습니다.

Abstract
적절한 access control 없이 사용자가 제어하는 값을 포함하는 LDAP 문을 실행하면 공격자가 허가 받지 않은 레코드에 접근할 수 있습니다.
Explanation
사실상 authentication 없이 익명의 바인딩에서 LDAP 쿼리를 실행하면 공격자가 빈약하게 구성된 LDAP 환경을 남용할 수 있습니다.

예제 1: 다음 코드는 익명 바운딩을 사용하여 DirContext ctx를 생성합니다.


...
env.put(Context.SECURITY_AUTHENTICATION, "none");
DirContext ctx = new InitialDirContext(env);
...
ctx에 대해 실행된 모든 LDAP 쿼리는 authentication 및 access control 없이 수행됩니다. 공격자는 디렉터리의 액세스 제어 메커니즘으로 보호되는 레코드에 대한 액세스를 얻기 위해 예기치 못한 방법으로 이러한 쿼리 중 하나를 조작할 수도 있습니다.

Abstract
매개 변수로 전달되는 표시기를 기준으로 권한 부여 검사를 건너뛰는 메서드는 사용자 제어 표시기를 사용하여 호출하면 안 됩니다.
Explanation
Access Control: 권한 부여 무시 문제는 다음과 같은 경우에 발생합니다.

1. 신뢰할 수 없는 소스를 통해 데이터가 프로그램에 입력됩니다.

2. 사용자 제어 데이터가 메서드에 매개 변수로 전달되어 해당 메서드가 내부의 권한 부여 검사를 건너뜁니다.
예제 1: 다음 코드는 직원 데이터를 가져오는 메서드에 사용자 제어 표시기를 제공합니다.

...
PARAMETERS: p_xfeld TYPE xfeld.
...
CALL FUNCTION 'BAPI_EMPLOYEE_GETDATA'
EXPORTING
employee_id = emp_id
authority_check = p_xfeld
IMPORTING
return = ret
TABLES
org_assignment = org_data
personal_data = pers_data
internal_control = con_data
communication = comm_data
archivelink = arlink.
...


공격자가 p_xfeld 매개 변수에 공백을 제공하면 직원의 개인 정보 및 연락처 정보를 반환하기 전에 권한 부여 검사가 수행되지 않습니다.

Abstract
적절한 access control 없이 사용자가 제어하는 값을 사용하여 Azure 큐/Blob에 접근하는 경우 공격자가 권한 없는 큐/blob 및 해당 메시지/콘텐트를 확인/수정/삭제할 수 있습니다.
Explanation
Azure 클라우드 access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 권한 없는 큐/blob 및 해당 메시지/콘텐트를 확인/수정/삭제하는 데 데이터가 사용되는 경우
예제 1: 다음 코드에서는 지정된 큐와 해당 메시지를 삭제합니다.


...
var queueName = queryStringData['name'];
var queueSvc;
queueSvc = azureStorage.createQueueService();
...
queueSvc.deleteQueue(queueName, option, function(error, response){
if(!error){
// all the messages has been deleted
}
});
...
예제 2: 다음 코드에서는 지정된 blob 컨테이너와 해당 콘텐트를 삭제합니다.


...
var containerName = queryStringData['name'];
var blobSvc;
blobSvc = azureStorage.createBlobService();
...
blobSvc.deleteContainer(containerName, function (error, response) {
if (!error) {
// all the content in the given container has been deleted
}
});
...
Example 1Example 2의 코드는 현재 사용자/프로그램에 속하는 지정된 큐/blob 컨테이너 및 해당 메시지/콘텐트를 삭제하지만 공격자는 해당 Azure 계정의 모든 큐/blob를 삭제할 수 있습니다. 이 예제의 코드는 사용자/프로그램에게 요청한 큐/blob를 지울 권한이 있는지를 확인하지 않으므로 현재 사용자/프로그램에 속하지 않는 큐/blob도 지웁니다.

Abstract
응용 프로그램이 대/소문자를 구분하지 않는 방식으로 Android 패키지를 사용자가 제어하는 값과 비교하며, 이로 인해 공격자가 패키지 이름에 기반하여 액세스 제어를 우회할 수 있습니다.
Explanation
Android에서 패키지 이름은 대/소문자를 구분하기 때문에 대/소문자를 구분하는 방식으로 비교해야 합니다. 악성 응용 프로그램이 대/소문자가 다른 유사한 패키지를 공유하여 액세스 제어를 우회할 수 있습니다.

예제 1: 다음 코드는 액세스 제어 용도로 안전하지 않은 문자열 비교를 수행합니다.


public boolean isTrusted(String paramString) {
if (this._applicationContext.getPackageName().equalsIgnoreCase(paramString)) {
return true;
}

Abstract
적절한 access control 없이 사용자가 제어하는 기본 키를 포함하는 SQL 문을 실행하면 공격자가 허가 받지 않은 레코드를 볼 수 있습니다.
Explanation
데이터베이스 Access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 데이터는 SQL 쿼리에서 기본 키의 값을 지정하는 데 사용됩니다.
예제 1: 다음 코드는 정수에 의존하기 때문에 SQL injection 취약점에 취약하지 않은 문을 사용하여 지정한 ID([1])와 일치하는 송장을 검색하는 SQL 쿼리를 생성하여 실행합니다. ID는 현재 인증된 사용자와 관련이 있는 모든 송장 목록에서 선택합니다.


DATA: id TYPE i.
...
id = request->get_form_field( 'invoiceID' ).

CONCATENATE `INVOICEID = '` id `'` INTO cl_where.
SELECT *
FROM invoices
INTO CORRESPONDING FIELDS OF TABLE itab_invoices
WHERE (cl_where).
ENDSELECT.
...


문제는 개발자가 ID의 가능한 모든 값을 고려할 수 없다는 점입니다. 인터페이스에서 현재 사용자의 송장 ID 목록을 생성하더라도 공격자는 이 인터페이스를 무시하고 원하는 송장을 요청할 수 있습니다. 이 예제의 코드가 사용자가 요청한 송장에 접근할 수 있는 권한이 있는지 확인하지 않기 때문에 현재 사용자의 송장이 아닌 송장도 모두 표시합니다.

Abstract
적절한 access control 없이 사용자가 제어하는 기본 키를 포함하는 SQL 문을 실행하면 공격자가 허가 받지 않은 레코드를 볼 수 있습니다.
Explanation
데이터베이스 Access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 데이터는 SQL 쿼리에서 기본 키의 값을 지정하는 데 사용됩니다.
예제 1: 다음 코드는 메타 문자를 이스케이프 처리하고 SQL injection 취약성을 방지하는 매개 변수가 있는 SQL 문을 사용하여 지정한 ID [1]에 일치하는 송장을 검색하는 SQL 쿼리를 생성하여 실행합니다. ID는 현재 인증된 사용자와 관련이 있는 모든 송장 목록에서 선택합니다.


...
var params:Object = LoaderInfo(this.root.loaderInfo).parameters;
var id:int = int(Number(params["invoiceID"]));
var query:String = "SELECT * FROM invoices WHERE id = :id";

stmt.sqlConnection = conn;
stmt.text = query;
stmt.parameters[":id"] = id;
stmt.execute();
...


문제는 개발자가 id의 가능한 모든 값을 고려할 수 없다는 점입니다. 인터페이스에서 현재 사용자의 송장 ID 목록을 생성하더라도 공격자는 이 인터페이스를 무시하고 원하는 송장을 요청할 수 있습니다. 이 예제의 코드가 사용자가 요청한 송장에 접근할 수 있는 권한이 있는지 확인하지 않기 때문에 현재 사용자의 송장이 아닌 송장도 모두 표시합니다.

Abstract
적절한 액세스 제어가 없으면 사용자가 제공한 기본 키가 포함되었을 수 있는 SOQL/SOSL 문을 실행하는 경우 공격자가 권한이 없는 레코드를 볼 수 있습니다.
Explanation
데이터베이스 Access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 데이터는 SOQL/SOSL 쿼리에서 기본 키의 값을 지정하는 데 사용됩니다.
예제1: 다음 코드 예제에서, inputID 값은 사전 정의된 목록에서 제공되며, 바인딩 변수는 SOQL/SOSL injection을 방지하는 데 도움이 됩니다.


...
result = [SELECT Name, Phone FROM Contact WHERE (IsDeleted = false AND Id=:inputID)];
...


앞의 예제의 문제는 사전 정의된 ID 목록을 사용하여 사용자가 inputID의 값을 수정하지 못하도록 방지하기에는 불충분하다는 점입니다. 공격자가 인터페이스를 우회하고 다른 값으로 요청을 전송할 수 있는 경우 공격자는 다른 연락처 정보에 액세스할 수 있습니다. 이 예제의 코드는 사용자가 요청된 연락처에 액세스할 수 있는 권한이 있는지 확인하지 않으므로, 사용자가 볼 권한이 없는 경우에도 모든 연락처를 표시합니다.

Abstract
적절한 access control 없이 사용자가 제어하는 기본 키를 포함하는 SQL 문을 실행하면 공격자가 허가 받지 않은 레코드를 볼 수 있습니다.
Explanation
데이터베이스 Access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 데이터는 SQL 쿼리에서 기본 키의 값을 지정하는 데 사용됩니다.
예제 1: 다음 코드는 메타 문자를 이스케이프 처리하고 SQL injection 취약성을 예방하는 매개 변수가 있는 SQL 문을 사용하여 지정한 ID [1]에 일치하는 송장을 검색하는 SQL 쿼리를 생성하여 실행합니다. ID는 현재 인증된 사용자와 관련이 있는 모든 송장 목록에서 선택합니다.


...
CMyRecordset rs(&dbms);
rs.PrepareSQL("SELECT * FROM invoices WHERE id = ?");
rs.SetParam_int(0,atoi(r.Lookup("invoiceID").c_str()));
rs.SafeExecuteSQL();
...


문제는 개발자가 id의 가능한 모든 값을 고려할 수 없다는 점입니다. 인터페이스에서 현재 사용자의 송장 ID 목록을 생성하더라도 공격자는 이 인터페이스를 무시하고 원하는 송장을 요청할 수 있습니다. 이 예제의 코드가 사용자가 요청한 송장에 접근할 수 있는 권한이 있는지 확인하지 않기 때문에 현재 사용자의 송장이 아닌 송장도 모두 표시합니다.

문제는 개발자가 id의 가능한 모든 값을 고려할 수 없다는 점입니다. 인터페이스에서 현재 사용자의 송장 ID 목록을 생성하더라도 공격자는 이 인터페이스를 무시하고 원하는 송장을 요청할 수 있습니다. 이 예제의 코드가 사용자가 요청한 송장에 접근할 수 있는 권한이 있는지 확인하지 않기 때문에 현재 사용자의 송장이 아닌 송장도 모두 표시합니다.

Abstract
적절한 access control 없이 사용자가 제어하는 기본 키를 포함하는 SQL 문을 실행하면 공격자가 허가 받지 않은 레코드를 볼 수 있습니다.
Explanation
데이터베이스 Access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 데이터는 SQL 쿼리에서 기본 키의 값을 지정하는 데 사용됩니다.
예제 1: 다음 코드는 메타 문자를 이스케이프 처리하고 SQL injection 취약성을 예방하는 매개 변수가 있는 SQL 문을 사용하여 지정한 ID [1]에 일치하는 송장을 검색하는 SQL 쿼리를 생성하여 실행합니다. ID는 현재 인증된 사용자와 관련이 있는 모든 송장 목록에서 선택합니다.


...
id = Integer.decode(request.getParameter("invoiceID"));
String query = "SELECT * FROM invoices WHERE id = ?";
PreparedStatement stmt = conn.prepareStatement(query);
stmt.setInt(1, id);
ResultSet results = stmt.execute();
...


문제는 개발자가 id의 가능한 모든 값을 고려할 수 없다는 점입니다. 인터페이스에서 현재 사용자의 송장 ID 목록을 생성하더라도 공격자는 이 인터페이스를 무시하고 원하는 송장을 요청할 수 있습니다. 이 예제의 코드가 사용자가 요청한 송장에 접근할 수 있는 권한이 있는지 확인하지 않기 때문에 현재 사용자의 송장이 아닌 송장도 모두 표시합니다.

모바일 환경에서는 데이터베이스 Access control 오류와 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 Example 1을 Android 플랫폼에 맞게 조정합니다.


...
String id = this.getIntent().getExtras().getString("invoiceID");
String query = "SELECT * FROM invoices WHERE id = ?";
SQLiteDatabase db = this.openOrCreateDatabase("DB", MODE_PRIVATE, null);
Cursor c = db.rawQuery(query, new Object[]{id});
...


많은 최신 웹 프레임워크는 사용자 입력의 검증을 수행하기 위한 메커니즘을 제공합니다(Struts 및 Struts 2 포함). 확인되지 않은 입력의 소스를 강조하기 위해, Fortify 보안 코딩 규칙 팩은 악용 가능성을 낮추고 프레임워크 검증 메커니즘이 사용 중일 때마다 지원하는 증거에 포인터를 제공하여 Fortify Static Code Analyzer에서 보고한 문제의 우선 순위를 동적으로 재지정합니다. 이 기능을 Context-Sensitive Ranking(컨텍스트 감지 순위)이라고 부릅니다. Fortify 사용자의 감사 프로세스를 지원하기 위해, Fortify Software Security Research Group은 입력 소스에 적용된 검증 메커니즘에 따라 문제를 폴더로 그룹화하는 데이터 유효성 프로젝트 템플릿을 사용 가능하게 만듭니다.

Abstract
적절한 access control 없이 사용자가 제어하는 기본 키를 포함하는 SQL 문을 실행하면 공격자가 허가 받지 않은 레코드를 볼 수 있습니다.
Explanation
데이터베이스 Access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 데이터는 SQL 쿼리에서 기본 키의 값을 지정하는 데 사용됩니다.
예제 1: 다음 코드는 메타 문자를 이스케이프 처리하고 SQL injection 취약성을 예방하는 매개 변수가 있는 SQL 문을 사용하여 지정한 ID [1]에 일치하는 송장을 검색하는 SQL 쿼리를 생성하여 실행합니다. ID는 현재 인증된 사용자와 관련이 있는 모든 송장 목록에서 선택합니다.


...
$id = $_POST['id'];
$query = "SELECT * FROM invoices WHERE id = ?";
$stmt = $mysqli->prepare($query);
$stmt->bind_param('ss',$id);
$stmt->execute();
...


문제는 개발자가 id의 가능한 모든 값을 고려할 수 없다는 점입니다. 인터페이스에서 현재 사용자의 송장 ID 목록을 생성하더라도 공격자는 이 인터페이스를 무시하고 원하는 송장을 요청할 수 있습니다. 이 예제의 코드가 사용자가 요청한 송장에 접근할 수 있는 권한이 있는지 확인하지 않기 때문에 현재 사용자의 송장이 아닌 송장도 모두 표시합니다.

많은 최신 웹 프레임워크는 사용자 입력의 검증을 수행하기 위한 메커니즘을 제공합니다(Struts 및 Struts 2 포함). 확인되지 않은 입력의 소스를 강조하기 위해, Fortify 보안 코딩 규칙 팩은 악용 가능성을 낮추고 프레임워크 검증 메커니즘이 사용 중일 때마다 지원하는 증거에 포인터를 제공하여 Fortify Static Code Analyzer에서 보고한 문제의 우선 순위를 동적으로 재지정합니다. 이 기능을 Context-Sensitive Ranking(컨텍스트 감지 순위)이라고 부릅니다. Fortify 사용자의 감사 프로세스를 지원하기 위해, Fortify Software Security Research Group은 입력 소스에 적용된 검증 메커니즘에 따라 문제를 폴더로 그룹화하는 데이터 유효성 프로젝트 템플릿을 사용 가능하게 만듭니다.

Abstract
적절한 access control 없이 사용자가 제어하는 기본 키를 포함하는 SQL 문을 실행하면 공격자가 허가 받지 않은 레코드를 볼 수 있습니다.
Explanation
데이터베이스 Access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 데이터는 SQL 쿼리에서 기본 키의 값을 지정하는 데 사용됩니다.
예제 1: 다음 코드는 메타 문자를 이스케이프 처리하고 SQL injection 취약성을 방지하는 매개 변수가 있는 SQL 문을 사용하여 지정한 ID [1]에 일치하는 송장을 검색하는 SQL 쿼리를 생성하여 실행합니다. ID는 현재 인증된 사용자와 관련이 있는 모든 송장 목록에서 선택합니다.


...
id = req['invoiceID'].respond_to(:to_int)
query = "SELECT * FROM invoices WHERE id=?"
stmt = conn.prepare(query)
stmt.execute(id)
...


문제는 개발자가 id의 가능한 모든 값을 고려할 수 없다는 점입니다. 인터페이스에서 현재 사용자의 송장 ID 목록을 생성하더라도 공격자는 이 인터페이스를 무시하고 원하는 송장을 요청할 수 있습니다. 이 예제의 코드가 사용자가 요청한 송장에 접근할 수 있는 권한이 있는지 확인하지 않기 때문에 현재 사용자의 송장이 아닌 송장도 모두 표시합니다.

Abstract
적절한 access control 없이 사용자가 제어하는 기본 키를 포함하는 SQL 문을 실행하면 공격자가 허가 받지 않은 레코드를 볼 수 있습니다.
Explanation
데이터베이스 Access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.


2. 데이터는 SQL 쿼리에서 기본 키의 값을 지정하는 데 사용됩니다.
예제 1: 다음 코드는 메타 문자를 이스케이프 처리하고 SQL injection 취약성을 예방하는 매개 변수가 있는 SQL 문을 사용하여 지정한 ID [1]에 일치하는 송장을 검색하는 SQL 쿼리를 생성하여 실행합니다. ID는 현재 인증된 사용자와 관련이 있는 모든 송장 목록에서 선택합니다.


...
id = Request.Form("invoiceID")
strSQL = "SELECT * FROM invoices WHERE id = ?"
objADOCommand.CommandText = strSQL
objADOCommand.CommandType = adCmdText
set objADOParameter = objADOCommand.CreateParameter("id" , adString, adParamInput, 0, 0)
objADOCommand.Parameters("id") = id
...



문제는 개발자가 id의 가능한 모든 값을 고려할 수 없다는 점입니다. 인터페이스에서 현재 사용자의 송장 ID 목록을 생성하더라도 공격자는 이 인터페이스를 무시하고 원하는 송장을 요청할 수 있습니다. 이 예제의 코드가 사용자가 요청한 송장에 접근할 수 있는 권한이 있는지 확인하지 않기 때문에 현재 사용자의 송장이 아닌 송장도 모두 표시합니다.

Abstract
이 응용 프로그램은 기본 API에 대한 검증되지 않은 입력을 허용하고 공격자가 인증을 우회할 수 있도록 하는 속성을 설정합니다.
Explanation
기본적으로 ASP.NET 양식 인증은 인증 프로세스 중에 기본 API에 전달하기 전에 사용자 자격 증명을 검증합니다. 문제는 aspnet:UseLegacyFormsAuthenticationTicketCompatibility 설정을 사용하여 검증되지 않은 입력이 기본 API로 전달되도록 허용하고 공격자가 인증을 우회할 수 있도록 이 기능을 수정할 수 있다는 것입니다. 이 취약점 악용에 성공한 공격자는 알려진 사용자 이름에 대해 암호 없이 ASP.NET 양식 인증을 우회할 수 있습니다. 그런 다음 사이트에서 임의의 명령을 실행하는 것을 포함하여 피해 사용자의 컨텍스트에서 모든 작업을 수행할 수 있습니다.

예제 1: 다음 예에서, aspnet:UseLegacyFormsAuthenticationTicketCompatibilitytrue로 설정됩니다.

...
<appSettings>
<add key="aspnet:UseLegacyFormsAuthenticationTicketCompatibility" value="true" />
</appSettings>

예제 1: 현재 인증된 사용자의 직원 ID가 클라이언트 쪽 인터페이스에 의한 각 요청으로 자동 제출됩니다. 다음 코드는 LDAP 쿼리를 생성하기 전에 허용 목록을 사용하여 직원 이름을 정확하게 검증합니다. 이 검증은 LDAP injection 취약점을 예방하지만 코드가 취약해질 수 있습니다.


static string AllowlistVerify(string name) {
Regex pattern = new Regex(@"^[a-zA-Z\-\.']+$");
if (pattern.IsMatch(name)) {
return name;
}
return null;
}

...
string verifiedName = AllowlistVerify(managerName.Text.trim());
if(verifiedName != null) {
DirectorySearcher src = new DirectorySearcher("(manager=" + verifiedName + ")");
src.SearchRoot = de;
src.SearchScope = SearchScope.Subtree;

foreach(SearchResult res in src.FindAll()) {
...
}
}


문제는 개발자가 공격자가 empName의 다른 값을 제공할 경우 발생될 일에 대해 고려하지 못했다는 점입니다. 인터페이스에서 현재 사용자의 직원 ID를 자동으로 제공하지만 공격자는 악의적인 요청의 일부로 다른 값을 제공할 수 있습니다. 이 예제의 코드가 익명의 바인딩에서 쿼리를 실행하므로 현재 인증된 사용자의 ID와 관계 없이 올바른 직원 ID에 대한 디렉터리 항목을 반환할 것입니다.

Abstract
적절한 access control 없이 사용자가 제어하는 값을 포함하는 LDAP 문을 실행하면 공격자가 허가 받지 않은 디렉터리 항목에 접근할 수 있습니다.
Explanation
데이터베이스 Access control 오류는 다음 경우에 발생합니다.

1. 신뢰할 수 없는 소스에서 데이터가 프로그램에 입력됩니다.

2. 데이터는 LDAP 쿼리에서 데이터 값을 지정하는 데 사용됩니다.
예제 1: 다음 코드는 LDAP 쿼리를 생성하기 전에 허용 목록을 사용하여 소켓에서 읽은 직원 이름을 검증합니다. 이 검증은 LDAP injection 취약점을 예방하지만 코드가 취약해질 수 있습니다.


char* allowlist_verify(char* name) {
const char *error;
int errOffset;
char* regex = "^[a-zA-Z\\-\\.']+$";
pcre* re = pcre_compile(regex, 0, &err, &errOffset, NULL);
int rc = pcre_exec(re, NULL, name, strlen(name), 0, 0, NULL, 0);
if (rc == 1)
return name;
return NULL;
}
...
fgets(managerName, sizeof(managerName), socket);
char* verified_name = allowlist_verify(managerName);
if(verified_name != NULL) {

filter, NULL, 0, NULL, NULL, LDAP_NO_LIMIT,
LDAP_NO_LIMIT, &result ) ) == LDAP_SUCCESS ) {
...
}
}


문제는 개발자가 공격자가 username의 다른 값을 제공할 경우 발생될 일에 대해 고려하지 못했다는 점입니다. 이 예제의 코드가 익명의 바인딩에서 쿼리를 실행하므로 현재 인증된 사용자의 ID와 관계 없이 올바른 직원 ID에 대한 디렉터리 항목을 반환할 것입니다.

Abstract
적절한 권한 검사가 없으면 프로그램이 권한이 없는 사용자에게 제한된 트랜잭션을 시작하도록 허용할 수도 있습니다.
Explanation
사용자가 수동으로 새로운 트랜잭션을 시작할 때마다 SAP 시스템은 해당 사용자가 트랜잭션 실행 권한이 있는지 자동으로 검사합니다. 하지만 사용자가 CALL TRANSACTION 문 호출을 통해 프로그래밍 방식으로 새로운 트랜잭션을 시작하는 경우에는 이러한 검사가 기본으로 수행되지는 않습니다. 이 문 이전에 명시적인 권한 부여 검사가 수행되지 않는다면 ABAP 프로그램을 실행하는 사용자가 허용되지 않아야 할 트랜잭션을 시작할 수 있습니다.

예제 1: 다음 코드는 ABAP 프로그램을 실행하는 트랜잭션을 호출합니다.


...
CALL TRANSACTION 'SA38'.
...


이 경우, 코드를 실행하는 사용자가 원래는 권한이 없음에도 ABAP 프로그램을 시작하고 시스템에 대한 전체 제어 권한을 확보할 수도 있습니다.

Abstract
사용자 입력이 MQ 개체 설명자의 필드를 제어하는 것을 허용하면 그렇지 않을 때 보호할 수 있는 MQ 리소스를 공격자가 접근하거나 수정할 수 있습니다.
Explanation
응용 프로그램이 MQ 개체를 열 때 수행할 권한 부여 검사의 종류를 결정하는 데 사용할 값을 공격자가 제공하게 되면, 다른 방법으로는 접근할 수 없는 개체를 열려고 할 때 공격자가 모든 access control 검사를 통과할 가능성이 있습니다.

예제: 다음 COBOL 코드 조각은 터미널에서 값을 읽어 이를 MQ 개체 설정파일의 MQOD-ALTERNATEUSERIDMQOD-ALTERNATESECURITYID 필드를 제어하는 데 사용합니다.


...
10 MQOD.
** Alternate user identifier
15 MQOD-ALTERNATEUSERID PIC X(12).
** Alternate security identifier
15 MQOD-ALTERNATESECURITYID PIC X(40).
...
...
ACCEPT MQOD-ALTERNATEUSERID.
ACCEPT MQOD-ALTERNATESECURITYID.
CALL 'MQOPEN' USING HCONN, MQOD, OPTS, HOBJ, COMPOCODE REASON.
...


이 예제에서 공격자는 열려 있는 MQ 개체에서 access control 검사를 통과시키는 값을 제공할 수 있습니다.

일반적으로 사용자가 제공하거나 신뢰할 수 없는 데이터가 민감한 값을 제어하도록 해서는 안 됩니다.

Abstract
프로그램은 더 권한이 높은 사용자를 위해 예약된 명령을 무단 사용자가 수행하도록 허용할 수 있습니다.
Explanation
보통 SAP 응용 프로그램에서의 권한 부여 검사는 응용 프로그램을 실행하는 사용자, 즉 로그온한 사용자에 대해서 수행됩니다. 하지만 다음과 같은 프로그래밍 방식으로 다른 사용자(로그온한 사용자 이외의 사용자)에 대한 권한 부여를 검사하는 것도 가능합니다.
1. AUTHORITY-CHECK 문을 추가 FOR USER와 함께 사용
2. 지정된 사용자로 AUTHORITY_CHECK 함수 모듈 호출
3. 지정된 사용자로 SU_RAUTH_CHECK_FOR_USER 함수 모듈 호출

이러한 검사가 경우에 따라 필요할 수도 있지만 이러한 검사로 인해 권한 상승이라는 보안 위험에 노출될 수도 있습니다. 권한 부여 검사에 사용되는 '사용자 ID' 입력을 제어할 수 있는 악의적인 사용자가 알려진 슈퍼 사용자(예: SAP*, DDIC 등)를 지정하여 다른 방법으로는 금지된 접근 권한을 사용자에게 제공하도록 시스템을 속일 수 있습니다.

권한 부여 검사에 사용되는 '사용자 ID'를 사용자가 직접 제어할 수 없는 경우에도 다른 사용자의 권한 부여 탐색은 잘못된 관행으로 피해야 할 작업입니다. 권한 부여 검사 수행 시 로그온한 사용자(sy-uname)를 명시적으로 지정하지 않아야 합니다. 이것이 기본 동작입니다. 명시적으로 지정하는 행위는 sy-uname에 대한 검사가 실제로 실행되기 전에 조작될 가능성만 높일 뿐입니다. 따라서 일반적으로 다른 사용자에 대한 권한 부여 검사는 건너뛰는 것이 좋습니다. 특히 명시적으로 로그온한 사용자를 지정하지 않는 것이 좋습니다.

예제 1: 다음 코드는 ABAP 프로그램을 실행할 수 있는 트랜잭션 호출 이전에 사용자 권한 부여를 검사합니다.


...
AUTHORITY-CHECK OBJECT 'S_TCODE' FOR USER v_user
ID 'TCD' FIELD 'SA38'.
IF sy-subrc = 0.
CALL TRANSACTION 'SA38'.
ELSE.
...


이 경우, 원래는 권한이 없는 사용자가 알려진 슈퍼 유저(예: SAP* 또는 DDIC 등)를 v_user 변수에 제공함으로써 어떠한 ABAP 프로그램이라도 시작할 수 있게 됩니다.

Abstract
신뢰할 수 없는 코드에 이 함수를 호출하면 공격자가 제한된 패키지에 접근할 수 있고 임의의 코드를 실행할 수 있는 능력을 갖게 됩니다.
Explanation
즉각적인 호출자의 클래스 로더 검사 사용 작업을 수행하는 Java API는 주의해서 사용해야 합니다. 이러한 API는 실행 체인의 모든 호출자가 필요한 보안 권한을 부여받도록 보장하는 SecurityManager 검사를 무시합니다. 즉각적인 호출자의 클래스 로더에 대한 액세스 확인만으로 실행 체인의 일부 호출자가 필요한 권한 없이 리소스에 접근할 수 있게 되는 권한 상승 문제가 유발될 수 있습니다. 따라서 이러한 API는 시스템 보안을 손상시킬 수 있으므로 신뢰할 수 없는 코드 대신에 호출하지 말아야 합니다.



이러한 API에 접근 가능한 신뢰할 수 없는 소스 또는 신뢰할 수 없는 환경의 Java Applet은 악성 코드를 실행하고 시스템 보안을 손상시킬 수 있습니다.

Abstract
Apex 클래스에는 사용자 공유 규칙을 적용하지 않고 실행할 수 있는 데이터베이스 작업이 포함되어 있습니다.
Explanation
Salesforce 응용 프로그램은 공유 규칙을 사용하여 사용자 권한 및 데이터베이스 레코드에 대한 액세스를 제어합니다. 그러나 Apex에서 사용자 공유 규칙이 항상 적용되는 것은 아닙니다. 규칙이 적용되는 방식을 변경하는 다른 공유 키워드를 사용하여 Apex 클래스를 선언할 수 있기 때문입니다. 다음의 세 가지 공유 키워드 중 하나로 클래스를 선언할 수 있습니다.
- with sharing: 사용자 공유 규칙이 적용됩니다.
- without sharing: 공유 규칙이 적용되지 않습니다.
- inherited sharing: 호출 클래스의 공유 규칙이 적용됩니다. 호출 클래스가 공유 키워드를 지정하지 않거나 클래스 자체가 Visualforce 컨트롤러와 같은 진입점인 경우에는 사용자 공유 규칙이 기본적으로 적용됩니다.
공유 키워드가 선언되어 있지 않으면 클래스는 호출 클래스의 공유 모드(있는 경우)를 상속합니다. 그 외의 경우에는 공유 규칙이 적용되지 않습니다.
예제 1: 다음 3개 Apex 클래스에는 모두 데이터베이스 쿼리 호출용으로 안전하지 않은 공유 키워드가 포함되어 있습니다.

public class TestClass1 {
public List<Contact> getAllTheSecrets() {
return Database.query('SELECT Name FROM Contact');
}
}
public without sharing class TestClass2 {
public List<Contact> getAllTheSecrets() {
return Database.query('SELECT Name FROM Contact');
}
}
public inherited sharing class TestClass3 {
public List<Contact> getAllTheSecrets() {
return Database.query('SELECT Name FROM Contact');
}
}
TestClass1TestClass2가 안전하지 않은 이유는 사용자 공유 규칙을 적용하지 않고도 레코드를 검색할 수 있기 때문입니다.
TestClass3 의 경우에는 기본적으로 공유 규칙을 적용하므로 더 안전합니다. 그러나 without sharing을 명시적으로 선언하는 클래스에서 getAllTheSecrets() 함수를 호출하는 경우에는 여전히 무단 액세스 권한을 부여할 수 있습니다.

Abstract
약한 보안 제약 조건은 보안에 중요한 리소스에 대한 적절한 보호를 제공하지 않습니다.
Explanation


단일 <security constraint> 요소는 프로그램에 RBAC(Role-Based Access Control)가 사용되고 있지 않음을 암시합니다. RBAC는 보안 웹 응용 프로그램에서 민감한 작업의 보호를 위해 널리 용인되는 모범 사례입니다. 민감한 작업 또는 데이터에 대한 액세스를 제공하는 응용 프로그램의 경우 권한이 없는 사용자의 액세스를 차단하는 충분한 제어가 없을 수 있습니다. 또한 <url-pattern>에 와일드카드(*)가 있는 경우 패턴이 지나치게 광범위하다는 표시일 수 있습니다.

Abstract
사용자가 HTTP와 HTTPS 사이를 이동할 수 있게 되면 응용 프로그램이 세션 하이재킹에 취약해집니다.
Explanation
많은 응용 프로그램은 쿠키를 사용하여 사용자 세션 ID를 통신합니다. HTTPS를 통해 응용 프로그램에 액세스하면 쿠키가 보호됩니다(공격자가 쿠키를 스니핑할 수 없음). 그러나 개발자가 응용 프로그램의 민감하지 않은 부분에 대한 HTTP 접근을 허용할 경우, 세션 ID를 도난당할 수 있습니다. 사용자가 사이트의 보호되지 않은 부분을 탐색하면 세션 ID가 포함된 쿠키가 자유롭게 전송됩니다. 공격자가 트래픽을 스니핑하면 세션 ID를 보고 이를 사용하여 사용자 세션을 제어할 수 있습니다.


다음 예제는 비보안 채널과 보안 채널을 혼합한 구성을 보여줍니다.
