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.


...
public abstract class Inherit_AA
{
[AllowAnonymous]

}
}

public class Authorization_Test:Inherit_AA

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.

desc.dataflow.cpp.access_control_anonymous_ldap_bind
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
적절한 액세스 제어 없이 사용자가 제어하는 값이 포함된 LDAP 문을 실행하면 공격자가 권한이 없는 레코드에 액세스할 수 있게 됩니다.
Explanation
실질적으로 인증 없이 익명 바인딩으로 LDAP 쿼리를 실행하는 경우 공격자는 잘못 구성된 LDAP 환경을 남용할 수 있습니다.

예제 1: 다음 코드는 사용자가 빈 암호를 입력하는 경우 익명 바인딩을 생성합니다.


...
$ldapbind = ldap_bind ($ldap, $dn, $password = "" );
...


이 연결을 통해 실행되는 모든 후속 LDAP 쿼리는 인증 및 액세스 제어 없이 수행됩니다. 공격자는 이러한 쿼리 중 하나를 예상하지 못한 방법으로 조작하여 디렉터리의 액세스 제어 메커니즘으로 보호될 수 있는 레코드에 대한 액세스 권한을 얻을 수 있습니다.

desc.semantic.php.access_control_anonymous_ldap_bind
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 취약점을 예방하는, 매개 변수가 있는 SQL 문을 사용하여 지정한 ID와 일치하는 송장을 검색하는 SQL 쿼리를 생성하여 실행합니다[1]. ID는 현재 인증된 사용자와 관련이 있는 모든 송장 목록에서 선택합니다.


...
ACCEPT ID.
EXEC SQL
DECLARE C1 CURSOR FOR
SELECT INVNO, INVDATE, INVTOTAL
FROM INVOICES
WHERE INVOICEID = :ID
END-EXEC.
...


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.

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
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>

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: 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: 현재 인증된 사용자의 직원 ID가 클라이언트 쪽 인터페이스에 의한 각 요청으로 자동 제공됩니다. 다음 코드는 LDAP 쿼리를 생성하는 데 사용하기 전에 직원 ID를 정수로 정확하게 검증합니다. 이 검증은 LDAP injection 취약점을 예방하지만 코드가 취약해질 수 있습니다.


...
env.put(Context.SECURITY_AUTHENTICATION, "none");
DirContext ctx = new InitialDirContext(env);

String empID = request.getParameter("empID");

try
{
int id = Integer.parseInt(empID);

BasicAttribute attr = new BasicAttribute("empID", empID);

NamingEnumeration employee =
ctx.search("ou=People,dc=example,dc=com",attr);
...



문제는 개발자가 공격자가 empID의 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
이 응용 프로그램은 위험한 압축을 활성화합니다.
Explanation

이 코드는 DangerousEnableCompressiontrue로 설정하여 'permessage-deflate' WebSocket 확장을 활성화합니다. 암호화된 연결을 통해 이 압축을 활성화하면 응용 프로그램이 CRIME 및 BREACH 공격에 노출됩니다.

예제 1: 다음 코드는 DangerousEnableCompressiontrue로 설정합니다.


app.Run(async context => {
using var websocket = await context.WebSockets.AcceptWebSocketAsync(new WebSocketAcceptContext() { DangerousEnableCompression = true });
await websocket.SendAsync(...);
await websocket.ReceiveAsync(...);
await websocket.CloseAsync(WebSocketCloseStatus.NormalClosure, null, default);
});
