Abstract
AI モデルのシステム プロンプトに未検証のデータを送信すると、攻撃者が出力を操作したり、許可されていないアクションを実行したりして、システムの整合性とデータのセキュリティを侵害する可能性があります。
Explanation
AI アプリケーションでは、システム プロンプトによって、前処理の指示や AI の応答をガイドするコンテキストが提供されます。攻撃者は、システム プロンプトとして埋め込まれると AI モデルの動作が変わって不正な操作を実行したり、機密情報を漏洩したりする可能性がある入力を作成できます。永続的なプロンプト インジェクションの場合、この信頼できない入力は通常は、Web リクエストではなく、データベースまたはバックエンド データ ストアから取得されます。

例 1: 次のコードは、Spring AI を使用する AI チャット クライアントへのシステム プロンプトのインジェクションを示しています。

@GetMapping("/prompt_injection_persistent")
String generation(String userInput1, ...) {
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM users WHERE ...");
String userName = "";

if (rs != null) {
rs.next();
userName = rs.getString("userName");
}

return this.clientBuilder.build().prompt()
.system("Assist the user " + userName)
.user(userInput1)
.call()
.content();
}


この例では、攻撃者はシステム プロンプトへの未検証の入力を操作し、セキュリティ侵害が引き起されるようにしています。

Abstract
ユーザー入力を含む SimpleDB select ステートメントを構築すると、攻撃者が承認されていないレコードにアクセスする可能性があります。
Explanation
Query String Injection の脆弱性が発生するのは次の場合です。
1. 信頼できないソースからデータがプログラムに入り込んだ場合。



2. データが SimpleDB クエリ文字列の動的な構築に使用された場合。

例 1: 次のコードは、ユーザーが指定した製品カテゴリに関連する領収書を検索する SimpleDB select() クエリを動的に構築し、実行します。ユーザーは結果を並び替えるカラムを指定することもできます。アプリケーションがすでに認証されており、このコードセグメントの前に customerID の値を設定していると仮定します。


...
String customerID = getAuthenticatedCustomerID(customerName, customerCredentials);
...
AmazonSimpleDBClient sdbc = new AmazonSimpleDBClient(appAWSCredentials);
String query = "select * from invoices where productCategory = '"
+ productCategory + "' and customerID = '"
+ customerID + "' order by '"
+ sortColumn + "' asc";
SelectResult sdbResult = sdbc.select(new SelectRequest(query));
...


このコードによって実行されるクエリは次のようになります。


select * from invoices
where productCategory = 'Fax Machines'
and customerID = '12345678'
order by 'price' asc


ただし、クエリは定数ベースのクエリ文字列とユーザー入力の文字列を連結して動的に構築されるため、productCategory および price に単一引用符が含まれない場合に限ってクエリは正しく動作します。しかし、攻撃者が、"Fax Machines' or productCategory = \"" という文字列を productCategory に、文字列 "\" order by 'price" を sortColumnに指定すると、クエリは次のようになります。


select * from invoices
where productCategory = 'Fax Machines' or productCategory = "'
and customerID = '12345678'
order by '" order by 'price' asc


また、さらに人間が読みやすい形式では、


select * from invoices
where productCategory = 'Fax Machines'
or productCategory = "' and customerID = '12345678' order by '"
order by 'price' asc


これらの入力では、攻撃者は customerID で必要な認証を回避でき、すべての顧客について 'Fax Machines' と一致する領収書のレコードを表示できます。

Abstract
ユーザー入力を含む SQLite クエリステートメントを構築すると、攻撃者が承認されていないレコードにアクセスする可能性があります。
Explanation
Query String Injection の脆弱性が発生するのは次の場合です。
1. 信頼できないソースからデータがプログラムに入り込んだ場合。



この場合、Fortify Static Code Analyzer はデータのソースが信頼できると判断できません。

2. データが SQLite クエリの動的な構築に使用された場合。

SQLite Query String Injection により、悪意のあるユーザーが承認されていないレコードにアクセスする可能性がありますが、データベースの状態は変更されることはありません。

例 1: 次のコードは、顧客とユーザーが指定した製品カテゴリに関連する領収書を検索する SQLite クエリを動的に構築し、実行します。ユーザーは結果を並び替えるカラムを指定することもできます。プログラムがすでに認証されており、このコードセグメントの前に customerID の値を設定していると仮定します。


...
productCategory = this.getIntent().getExtras().getString("productCategory");
sortColumn = this.getIntent().getExtras().getString("sortColumn");
customerID = getAuthenticatedCustomerID(customerName, customerCredentials);
c = invoicesDB.query(Uri.parse(invoices), columns, "productCategory = '" + productCategory + "' and customerID = '" + customerID + "'", null, null, null, "'" + sortColumn + "'asc", null);
...


このコードによって実行されるクエリは次のようになります。


select * from invoices
where productCategory = 'Fax Machines'
and customerID = '12345678'
order by 'price' asc


しかし、クエリは定数ベースのクエリ文字列とユーザー入力の文字列 productCategory を連結して、動的に構築されます。そのため、productCategory および sortColumn に単一引用符が含まれない場合にのみ、クエリは正しく動作します。攻撃者が、"Fax Machines' or productCategory = \"" という文字列を productCategory に、文字列 "\" order by 'price" を sortColumn に指定すると、クエリは次のようになります。


select * from invoices
where productCategory = 'Fax Machines' or productCategory = "'
and customerID = '12345678'
order by '" order by 'price' asc


また、さらに読みやすい形式では、


select * from invoices
where productCategory = 'Fax Machines'
or productCategory = "' and customerID = '12345678' order by '"
order by 'price' asc


これらの入力では、攻撃者は customerID で必要な認証を回避でき、すべての顧客について 'Fax Machines' と一致する領収書のレコードを表示できます。

Abstract
アプリケーションがアプリケーションを共有ストレージからインストールし、悪意のあるアプリケーションによるインストール対象のパッケージの置き換えが可能になります。
Explanation
アプリケーションがアプリケーションを共有ストレージからインストールしますが、このストレージには外部ストレージの読み取り/書き込み権限を持つアプリケーションが書き込み可能です。 Race Condition によって、フォルダを監視している悪意のあるアプリケーションはダウンロード済みの APK ファイルを、インストール プロセスで正規の更新の代わりに使用される代替 APK ファイルと交換することができます。

例 1: 次のコードは、アプリケーションを共有ストレージからインストールします。


Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/download/" + "app.apk")), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

Abstract
静的フィールドを新しいオブジェクトに割り当てると、他の変数の初期化に依存している場合でもコンストラクターが呼び出され、オブジェクトが正しく初期化されない可能性があります。
Explanation
Java クラスが初期化された場合、クラスで宣言された static フィールドの初期化子をクラス コンストラクターより前にコールします。つまり、割り当てられたコンストラクターはその他のコードの前にコールされ、初期化されるその他のフィールドや変数にコンストラクターが依存する場合、部分的に初期化されたオブジェクトや誤った値で初期化されたオブジェクトにつながる可能性があります。

例 1: 次のクラスでは static フィールドを宣言し、新しいオブジェクトに割り当てています。


...
public class Box{
public int area;
public static final int width = 10;
public static final Box box = new Box();
public static final int height = (int) (Math.random() * 100);

public Box(){
area = width * height;
}
...
}
...
Example 1 では、width の値が 10 であるため、開発者は box.area が 10 の倍数のランダム整数であると予想します。しかし実際は、常にハードコーディングされた 0 の値です。コンパイル時定数で宣言された static final フィールドは最初に初期化され、順番に実行されます。これは、height はコンパイル時定数ではないため box の宣言の後に宣言され、コンストラクターはフィールド height が初期化される前にコールされることを意味します。

例 2: 次のクラスでは、相互に依存する static フィールドを宣言しています。


...
class Foo{
public static final int f = Bar.b - 1;
...
}
...
class Bar{
public static final int b = Foo.f + 1;
...
}

This example is perhaps easier to identify, but would be dependent on which class is loaded first by the JVM. In this example Foo.f could be either -1 or 0, and Bar.b could be either 0 or 1.

Abstract
java.text.Format にあるメソッド parse() および format() には、あるユーザーが別のユーザーのデータを表示できるという設計上の不備が含まれています。
Explanation
java.text.Format にあるメソッド parse() および format() には、あるユーザーが別のユーザーのデータを表示できるという Race Condition が含まれています。

例 1: 次のコードは、この設計上の不備がどのようになっているのかを示しています。


public class Common {

private static SimpleDateFormat dateFormat;
...

public String format(Date date) {
return dateFormat.format(date);
}
...

final OtherClass dateFormatAccess=new OtherClass();
...

public void function_running_in_thread1(){
System.out.println("Time in thread 1 should be 12/31/69 4:00 PM, found: "+ dateFormatAccess.format(new Date(0)));
}

public void function_running_in_thread2(){
System.out.println("Time in thread 2 should be around 12/29/09 6:26 AM, found: "+ dateFormatAccess.format(new Date(System.currentTimeMillis())));
}
}


このコードは、単一ユーザーの環境では正しく動作しますが、2つのスレッドが同時に実行されると、下記の出力を生成する場合があります。

Time in thread 1 should be 12/31/69 4:00 PM, found: 12/31/69 4:00 PM
Time in thread 2 should be around 12/29/09 6:26 AM, found: 12/31/69 4:00 PM

この場合、format() の実装にある Race Condition のため、最初のスレッドの日付が2つ目のスレッドの出力に表示されています。

Abstract
サーブレットメンバーフィールドは、ユーザーが別のユーザーのデータを参照することを許してしまう可能性があります。
Explanation
サーブレットがひとつずつ発生することを多くのサーブレット開発者は理解していません。サーブレットのインスタンスはひとつしかなく、異なるスレッドにより同時に処理される複数のリクエストを取り扱うために、ひとつのインスタンスが使用および再使用されます

この誤解の結果、ユーザーが別のユーザーのデータを偶然に参照し得るようなサーブレットメンバーフィールドの使い方を開発者がすることがあります。言い換えるならば、ユーザーデータをサーブレットメンバーフィールドに格納すると、データアクセスの Race Condition となります。

例 1: 以下のサーブレットはメンバーフィールドのリクエストパラメーター値を格納し、後でパラメーター値をレスポンス出力ストリームに返します。


public class GuestBook extends HttpServlet {

String name;

protected void doPost (HttpServletRequest req, HttpServletResponse res) {
name = req.getParameter("name");
...
out.println(name + ", thanks for visiting!");
}
}


このコードは単一ユーザー環境では問題なく動作しますが、2 人のユーザーがほぼ同時にサーブレットにアクセスすると、2 つのリクエストハンドラースレッドが次のようにインターリーブされます。

スレッド 1: assign "Dick" to name
スレッド 2: assign "Jane" to name
スレッド 1: print "Jane, thanks for visiting!"
スレッド 2: print "Jane, thanks for visiting!"

したがって、最初のユーザーに 2 番目のユーザー名を表示します。

Abstract
static フィールドに格納されているデータベース接続は、スレッド間で共有されます。
Explanation
データベース接続など、トランザクションに関係するリソースオブジェクトは、一度に 1 つのトランザクションのみと関連付けることができます。そのため、接続をスレッド間で共有してはいけません。また、static フィールドに格納するべきでもありません。詳細については、J2EE 仕様 4.2.3 の項を参照してください。

例 1:

public class ConnectionManager {

private static Connection conn = initDbConn();

NULL ポインタの例外は通常、プログラマの想定が破られた結果として発生します。この問題には、少なくとも次の 3 種類があります。間接参照後チェック、チェック後間接参照、格納後間接参照です。間接参照後チェックのエラーが発生するのは、プログラムで、ポインタが null であるかを確認する前に、null の可能性があるポインタを間接参照する場合です。チェック後間接参照のエラーが発生するのは、プログラムが null に対して明示的チェックを実行したにも関わらず、null であることが判明しているポインタを間接参照した場合です。この種のエラーの多くは、タイプミスかプログラマの不注意が原因です。格納後間接参照のエラーは、プログラムが明示的にポインタを null に設定し、後でそのポインタを間接参照した場合に発生します。このエラーは通常、変数の宣言時にプログラマがその変数を null に初期化したことが原因で発生します。

NULL ポインターの問題点の大半は一般にソフトウェアの信頼性の問題につながります。しかし、攻撃者が意図的に NULL ポインター間接参照を引き起こせる場合、その結果生じた例外を利用してセキュリティ ロジックをバイパスすることで Denial of Service 攻撃を実装したり、アプリケーションにデバッグ情報を開示させてそれ以降の攻撃に役立てたりすることができます。

例 1: 次のコードでは、プログラマはオブジェクト foonull であることを確認してから、それを誤って間接参照しています。fooif ステートメントでチェックされたときに null になっていると、null 間接参照 が発生し、これが NULL ポインター例外の原因となります。


if (foo is null) {
foo.SetBar(val);
...
}
例 2: 次のコードでは、プログラマは変数 foonull ではないと仮定しており、オブジェクトを間接参照することによってこの仮定を確認しています。しかし、その後プログラマが foonull を比較したときに、この仮定は成り立たなくなります。fooif ステートメントでチェックされたときに null であるとすれば、間接参照されたときにも null である可能性があり、これが NULL ポインタ例外の原因となる場合があります。間接参照が安全でないか、後で実行するチェックが不要であるかのいずれかです。


foo.SetBar(val);
...
if (foo is not null) {
...
}
例 3: 次のコードでは、プログラマは明示的に変数 foonull に設定しています。続いて、オブジェクトの null 値をチェックする前に foo を間接参照しています。


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

Abstract
プログラムでは潜在的に NULL ポインタを間接参照する可能性があり、これがセグメンテーション違反の原因になります。

例 1: 次のコードでは、プログラマは変数 ptrNULL ではないと仮定してします。この仮定は、プログラマがポインタを間接参照したときに明らかになります。その後プログラマが ptrNULL を比較したときに、この仮定は成り立たなくなります。ptrif ステートメントでチェックされたときに NULL であるとすれば、間接参照されたときにも NULL である可能性があり、これがセグメンテーション違反の原因となる場合があります。


ptr->field = val;
...
if (ptr != NULL) {
...
}
例 2: 次のコードでは、プログラマは変数 ptrNULL であることを確認してから、続いてそれを誤って間接参照しています。ptrif ステートメントでチェックされたときに NULL になっていると、null Dereference が発生し、これがセグメンテーション違反の原因となります。


if (ptr == null) {
ptr->field = val;

}
例 3: 次のコードでは、プログラマが文字列 '\0' (実際は 0) または NULL を忘れたため、NULL ポインタを間接参照し、セグメンテーション違反を引き起こしています。


if (ptr == '\0') {
*ptr = val;
...
}
例 4: 次のコードでは、プログラマは明示的に変数 ptrNULL に設定しています。続いて、オブジェクトの null 値をチェックする前に ptr を間接参照しています。


*ptr = NULL;

Abstract
プログラムでは NULL ポインタを間接参照する可能性があり、これが NULL ポインタ例外の原因になります。
Explanation
NULL ポインタの例外は通常、プログラマの想定が破られた結果として発生します。具体的には、チェック後間接参照のエラーが発生するのは、プログラムが null に対して明示的チェックを実行したにも関わらず、null であることが判明しているオブジェクトを間接参照した場合です。この種のエラーの多くは、タイプミスかプログラマの不注意が原因です。

例 1: 次のコードでは、プログラマは変数 foonull であることを確認してから、続いてそれを誤って間接参照しています。fooif ステートメントでチェックされたときに null になっていると、null Dereference が発生し、これが NULL ポインタ例外の原因となります。

Abstract
このアプリケーションは、信頼できるドメインを元にしているように見える任意のコンテンツを強制的にダウンロードさせる URL の作成を攻撃者に許可します。
Explanation
Reflected File Download (RFD) は、攻撃者が作成したフィッシング URL またはフィッシング ページにアクセスさせて、信頼できるドメインを元にしているように見える任意のコンテンツを含むファイルのダウンロードを開始するという脆弱性の 1 つです。ユーザーは対象のドメインを信頼しているため、ダウンロードしたファイルを開く可能性が高く、結果的に悪意のあるコードが実行されてしまいます。

攻撃者が RFD 攻撃を成功させるには、次の要件を満たす必要があります。
- ターゲット アプリケーションが、適切な検証またはエンコードなしでユーザー入力を反映している。これは、ペイロードを挿入するために使用されます。
- ターゲット アプリケーションが、許容的な URL を許可している。この結果、攻撃者が、ダウンロードされたファイルの名前と拡張子を操作する可能性があります。
- ターゲット アプリケーションの Content-Disposition ヘッダーの設定が間違っている。これにより、HTTP レスポンスの Content-Type ヘッダーと Content-Disposition ヘッダーまたはそのいずれかが攻撃者によって操作される可能性があるほか、ターゲット アプリケーションに、デフォルトではブラウザーにレンダリングされない Content-Type が含まれる場合があります。

たとえば、アプリケーションが Spring Web MVC ContentNegotiationManager を使用して、さまざまなレスポンス形式を動的に生成している場合、RFD 攻撃に必要な条件が整います。

ContentNegotiationManager は、リクエスト パス拡張に基づいてレスポンス形式を決定し、Java Activation Framework (JAF) を使用してクライアントが要求した形式により一致する Content-Type を探すように設定されます。また、リクエストの Accept ヘッダーで送信されるメディア タイプを介してレスポンス コンテンツ タイプを指定することをクライアントに許可します。

例 1: 次の例のアプリケーションは、パス拡張戦略と Java Activation Framework によってレスポンス コンテンツ タイプを決定するように設定されています。


<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorPathExtension" value="true" />
<property name="useJaf" value="true" />
</bean>
例 2: 次の例のアプリケーションは、リクエストの Accept ヘッダーによってレスポンス コンテンツ タイプを決定するように設定されています。


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


Spring 4.2.1 での ContentNegotiationManagerFactoryBean プロパティのデフォルト値は次のとおりです。

- useJaf: true
- favorPathExtension: true
- ignoreAcceptHeader: falseExample 1 の構成では、攻撃者が次のような悪意のある URL を作成することが可能です。

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

ContentNegotiationManager は、Java Activation Framework (activity.jar がクラスパスにある場合) を使用して、指定したファイル拡張子についてメディア タイプを解決しようとし、それに合わせてレスポンスの ContentType ヘッダーを設定します。この例では、ファイル拡張子は "bat" で、Content-Type ヘッダーは application/x-msdownload です (正確な Content-Type は、サーバーの OS と JAF の設定によって異なります)。その結果、この悪意のある URL にアクセスした被害者のマシンは、攻撃者が操作したコンテンツを含む ".bat" ファイルのダウンロードを自動的に開始します。その後、このファイルが実行されると、被害者のマシンは攻撃者のペイロードで指定されたコマンドを実行します。

Abstract
ユーザー入力でリソース ID を制御できるようにすると、本来保護されているシステムリソースに攻撃者がアクセスしたり変更したりできるようになる可能性があります。
Explanation
Resource Injection の問題点が発生するのは、次の 2 つの条件に一致した場合です。

1. システム リソースへのアクセスに使用される識別子を攻撃者が特定できる場合。

たとえば、ネットワーク リソースへの接続に使用されるポート番号を攻撃者が特定できる場合があります。

2. リソースを特定することにより、攻撃者が通常では許可されない権限を取得する場合。

たとえば、プログラムにより、サードパーティのサーバーに機密性が高い情報を送信する権限が攻撃者に与えられる可能性があります。



注: ファイル システムに格納されたリソースが関連するリソース インジェクションは、パス操作という名前の別のカテゴリで報告されます。この脆弱性の詳細については Path Manipulation の説明を参照してください。

例 1: 次のコードは HTTP リクエストから読み取ったホスト名を使用して FTP 接続を作成します。


...
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.
...


ユーザー入力により変更されたリソースの種類は、危険である可能性があるコンテンツの種類を示します。たとえば、File System と情報をやりとりするメソッドで使用される場合、ピリオド、スラッシュ、およびバックスラッシュなどの特殊文字を含んでいるデータは危険です。同様に、URL や URI を含むデータは、リモート接続を作成する関数には危険です。

Abstract
ユーザー入力でリソース ID を制御できるようにすると、本来保護されているシステムリソースに攻撃者がアクセスしたり変更したりできるようになる可能性があります。
Explanation
Resource Injection の問題点が発生するのは、次の 2 つの条件に一致した場合です。

1. システム リソースへのアクセスに使用される識別子を攻撃者が特定できる場合。

たとえば、ネットワーク リソースへの接続に使用されるポート番号を攻撃者が特定できる場合があります。

2. リソースを特定することにより、攻撃者が通常では許可されない権限を取得する場合。

たとえば、プログラムにより、サードパーティのサーバーに機密性が高い情報を送信する権限が攻撃者に与えられる可能性があります。

注: ファイル システムに格納されたリソースが関連するリソース インジェクションは、パス操作という名前の別のカテゴリで報告されます。この脆弱性の詳細については Path Manipulation の説明を参照してください。

例 1: 次のコードは、HTTP リクエストから読み取ったポート番号を使用してソケットを作成します。


int rPort = Int32.Parse(Request.Item("rPort"));
...
IPEndPoint endpoint = new IPEndPoint(address,rPort);
socket = new Socket(endpoint.AddressFamily,
SocketType.Stream, ProtocolType.Tcp);
socket.Connect(endpoint);
...


ユーザー入力により変更されたリソースの種類は、危険である可能性があるコンテンツの種類を示します。たとえば、File System と情報をやりとりするメソッドで使用される場合、ピリオド、スラッシュ、およびバックスラッシュなどの特殊文字を含んでいるデータは危険です。同様に、URL や URI を含むデータは、リモート接続を作成する関数には危険です。

Abstract
ユーザー入力でリソース ID を制御できるようにすると、本来保護されているシステムリソースに攻撃者がアクセスしたり変更したりできるようになる可能性があります。
Explanation
Resource Injection の問題点が発生するのは、次の 2 つの条件に一致した場合です。

1. システム リソースへのアクセスに使用される識別子を攻撃者が特定できる場合。

たとえば、開かれるファイルの名前の一部や使用されるポート番号を攻撃者が特定できる場合があります。

2. リソースを特定することにより、攻撃者が通常では許可されない権限を取得する場合。

たとえば、プログラムにより攻撃者に権限が付与され、指定ファイルを上書きしたり、攻撃者によって制御される設定で実行したりできる可能性があります。

例 1: 次の ColdFusion コードは Java ServerSocket オブジェクトを作成し、HTTP リクエストから読み取ったポート番号を使用してソケットを作成します。


<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
ユーザー入力でリソース ID を制御できるようにすると、本来保護されているシステムリソースに攻撃者がアクセスしたり変更したりできるようになる可能性があります。
Explanation
Resource Injection の問題点が発生するのは、次の 2 つの条件に一致した場合です。

1.システム リソースへのアクセスに使用される識別子を攻撃者が特定できる場合。

たとえば、攻撃者がポート番号を特定し、それをネットワーク リソースへの接続に使用する可能性があります。

2.リソースを特定することにより、攻撃者が通常では許可されない権限を取得する場合。

たとえば、プログラムにより、サードパーティのサーバーに機密性が高い情報を送信する権限が攻撃者に与えられる可能性があります。



注:ファイル システムに格納されたリソースが関連するリソース インジェクションは、パス操作という名前の別のカテゴリで報告されます。この脆弱性の詳細については Path Manipulation の説明を参照してください。

例 1: 次のコードは、HTTP リクエストから読み取ったポート番号を使用してソケットを作成します。


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);
});
...


一部には、モバイル環境ではリソース インジェクションのような Web アプリケーションの古典的な脆弱性は意味がなく、自分に降りかかる攻撃をするはずがない、という見方があります。しかし忘れてはならないモバイルプラットフォームの基本は、さまざまなソースからアプリケーションをダウンロードして同じデバイス上で一緒に実行することです。このため、たとえばバンキングアプリケーションのすぐ隣でマルウェアの一部を実行する可能性が高くなり、モバイルアプリケーションの攻撃面を拡張し、プロセス間通信なども含める必要があります。

Abstract
ユーザー入力でリソース ID を制御できるようにすると、本来保護されているシステムリソースに攻撃者がアクセスしたり変更したりできるようになる可能性があります。

注:ファイル システムに格納されたリソースが関連するリソース インジェクションは、パス操作という名前の別のカテゴリで報告されます。この脆弱性の詳細については Path Manipulation の説明を参照してください。

例 1: 次のコードは HTTP リクエストから読み取ったデバイス名を使用して fd に関連付けられているソケットをそのデバイスにバインドします。


func someHandler(w http.ResponseWriter, r *http.Request){
r.parseForm()
deviceName := r.FormValue("device")

Abstract
ユーザー入力でリソース ID を制御できるようにすると、本来保護されているシステムリソースに攻撃者がアクセスしたり変更したりできるようになる可能性があります。
Explanation
Resource Injection の問題点が発生するのは、次の 2 つの条件に一致した場合です。

1. システム リソースへのアクセスに使用される識別子を攻撃者が特定できる場合。

たとえば、ネットワーク リソースへの接続に使用されるポート番号を攻撃者が特定できる場合があります。

2. リソースを特定することにより、攻撃者が通常では許可されない権限を取得する場合。

たとえば、プログラムにより、サードパーティのサーバーに機密性が高い情報を送信する権限が攻撃者に与えられる可能性があります。



注: ファイル システムに格納されたリソースが関連するリソース インジェクションは、パス操作という名前の別のカテゴリで報告されます。この脆弱性の詳細については Path Manipulation の説明を参照してください。

例 1: 次のコードは HTTP リクエストから読み取った URL を使用してソケットを作成します。


var socket = new WebSocket(document.URL.indexOf("url=")+20);


ユーザー入力により変更されたリソースの種類は、危険である可能性があるコンテンツの種類を示します。たとえば、File System と情報をやりとりするメソッドで使用される場合、ピリオド、スラッシュ、およびバックスラッシュなどの特殊文字を含んでいるデータは危険です。同様に、URL や URI を含むデータは、リモート接続を作成する関数には危険です。

Abstract
攻撃者はリソース ID 引数を制御できるため、本来保護されているシステム リソースにアクセスしたり変更したりできるようになる可能性があります。
Explanation
Resource Injection の問題点が発生するのは、次の 2 つの条件に一致した場合です。

1. システム リソースへのアクセスに使用される識別子を攻撃者が特定できる場合。

たとえば、ネットワーク リソースへの接続に使用されるポート番号や入力ファイルのソースの場所を、攻撃者が特定できる場合があります。

2. リソースを特定することにより、攻撃者が通常では許可されない権限を取得する場合。

たとえば、プログラムにより、サードパーティのサーバーに機密性が高い情報を送信する権限が攻撃者に与えられる可能性があります。

注: ファイル システムに格納されたリソースが関連するリソース インジェクションは、パス操作という名前の別のカテゴリで報告されます。この脆弱性の詳細については Path Manipulation の説明を参照してください。

例 1: 次のコードは、リクエストから読み取られたホストを使用しています。


...
char* rHost = getenv("host");
...
CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)rHost, 80, &readStream, &writeStream);
...


ユーザー入力により変更されたリソースの種類は、危険である可能性があるコンテンツの種類を示します。たとえば、File System と情報をやりとりするメソッドで使用される場合、ピリオド、スラッシュ、およびバックスラッシュなどの特殊文字を含んでいるデータは危険です。同様に、URL や URI を含むデータは、リモート接続を作成する関数には危険です。

Abstract
ユーザー入力でリソース ID を制御できるようにすると、本来保護されているシステムリソースに攻撃者がアクセスしたり変更したりできるようになる可能性があります。
Explanation
Resource Injection の問題点が発生するのは、次の 2 つの条件に一致した場合です。

1. システム リソースへのアクセスに使用される識別子を攻撃者が特定できる場合。

たとえば、ネットワーク リソースへの接続に使用されるポート番号を攻撃者が特定できる場合があります。

2. リソースを特定することにより、攻撃者が通常では許可されない権限を取得する場合。

たとえば、プログラムにより、サードパーティのサーバーに機密性が高い情報を送信する権限が攻撃者に与えられる可能性があります。



注: ファイル システムに格納されたリソースが関連するリソース インジェクションは、パス操作という名前の別のカテゴリで報告されます。この脆弱性の詳細については Path Manipulation の説明を参照してください。

例 1: 次のコードでは、HTTP リクエストから読み取ったホスト名を使用して、チケットの価格を決定するデータベースに接続しています。


host=request.GET['host']
dbconn = db.connect(host=host, port=1234, dbname=ticketdb)
c = dbconn.cursor()
...
result = c.execute('SELECT * FROM pricelist')
...


ユーザー入力により変更されたリソースの種類は、危険である可能性があるコンテンツの種類を示します。たとえば、File System と情報をやりとりするメソッドで使用される場合、ピリオド、スラッシュ、およびバックスラッシュなどの特殊文字を含んでいるデータは危険です。同様に、URL や URI を含むデータは、リモート接続を作成する関数には危険です。

Abstract
攻撃者はリソース ID 引数を制御できるため、本来保護されているシステム リソースにアクセスしたり変更したりできるようになる可能性があります。
Explanation
Resource Injection の問題点が発生するのは、次の 2 つの条件に一致した場合です。

1. システム リソースへのアクセスに使用される識別子を攻撃者が特定できる場合。

たとえば、ネットワーク リソースへの接続に使用されるポート番号や入力ファイルのソースの場所を、攻撃者が特定できる場合があります。

2. リソースを特定することにより、攻撃者が通常では許可されない権限を取得する場合。

たとえば、プログラムにより、サードパーティのサーバーに機密性が高い情報を送信する権限が攻撃者に与えられる可能性があります。

注: ファイル システムに格納されたリソースが関連するリソース インジェクションは、パス操作という名前の別のカテゴリで報告されます。この脆弱性の詳細については Path Manipulation の説明を参照してください。

例 1: 次のコードは、リクエストから読み取られたホストを使用しています。


...
func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
var inputStream : NSInputStream?
var outputStream : NSOutputStream?
...
var readStream : Unmanaged<CFReadStream>?

Abstract
ユーザー入力でリソース ID を制御できるようにすると、本来保護されているシステムリソースに攻撃者がアクセスしたり変更したりできるようになる可能性があります。
Explanation
Resource Injection の問題点が発生するのは、次の 2 つの条件に一致した場合です。

1. システム リソースへのアクセスに使用される識別子を攻撃者が特定できる場合。

たとえば、ネットワーク リソースへの接続に使用されるポート番号を攻撃者が特定できる場合があります。

2. リソースを特定することにより、攻撃者が通常では許可されない権限を取得する場合。

たとえば、プログラムにより、サードパーティのサーバーに機密性が高い情報を送信する権限が攻撃者に与えられる可能性があります。



注: ファイル システムに格納されたリソースが関連するリソース インジェクションは、パス操作という名前の別のカテゴリで報告されます。この脆弱性の詳細については Path Manipulation の説明を参照してください。

例 1: 次のコードは、HTTP リクエストから読み取ったポート番号を使用してソケットを作成します。


...
Begin MSWinsockLib.Winsock tcpServer
...
Dim Response As Response
Dim Request As Request
Dim Session As Session
Dim Application As Application
Dim Server As Server
Dim Port As Variant
Set Response = objContext("Response")
Set Request = objContext("Request")
Set Session = objContext("Session")
Set Application = objContext("Application")
Set Server = objContext("Server")
Set Port = Request.Form("port")
...
tcpServer.LocalPort = Port
tcpServer.Accept
...



ユーザー入力により変更されたリソースの種類は、危険である可能性があるコンテンツの種類を示します。たとえば、File System と情報をやりとりするメソッドで使用される場合、ピリオド、スラッシュ、およびバックスラッシュなどの特殊文字を含んでいるデータは危険です。同様に、URL や URI を含むデータは、リモート接続を作成する関数には危険です。

Abstract
アプリケーションは、ユーザーによって制御可能なパラメーターをブラウザーによって実行される JavaScript コールバック関数として反映するので、攻撃者は同じエンドポイントのドメイン上の任意のページで、任意の JavaScript 関数を実行できます。
Explanation
アプリケーションは、攻撃者の制御下にあるパラメーターを、ブラウザーが実行する JavaScript 関数の名前として使用します。 攻撃者は、最初に同じアプリケーションのドメイン上でターゲット ページをフレーム化し、次にターゲット ページ上で任意の JavaScript 関数を実行するために脆弱なページを参照する、悪意のあるサイトを作成する可能性があります。 悪用について大きな制限がいくつかありますが、この攻撃の影響は、Cross-Site Scripting の影響と似ています。 コールバック名として英数字とドット文字を使用できれば、攻撃者はページの要素を参照して操作することができます。

例 1: 次のコードは、コールバック関数名をユーザーが制御できる JSONP レスポンスを構成します。


@ControllerAdvice
public class JsonpAdvice extends AbstractJsonpResponseBodyAdvice {
public JsonpAdvice() {
super("callback");
}
}
GET /api/latest.json?callback=myCallbackFunction などのリクエストの場合、コントローラー メソッドは、次のようなレスポンスを生成します。


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>})


攻撃者は JSONP エンドポイントからのレスポンスをロードするために JavaScript の Script タグを使用することができ、その結果、myCallbackFunction 関数が実行されます。 攻撃者は、異なるコールバック名を使用して DOM を参照し、操作する可能性があります。 たとえば opener.document.body.someElemnt.firstChild.nextElementSibling.submit を使用してターゲット ページにフォームを配置し、送信することができます。

Abstract
アプリケーションは、リソース URI に対するユーザー制御のデータを使用して、サードパーティ製システムへのネットワーク接続を開始します。
Explanation
アプリケーション サーバーによるネットワーク接続に対して攻撃者が影響を及ぼす可能性がある場合、サーバー側のリクエスト フォージェリが発生します。ネットワーク接続がアプリケーション サーバーの内部 IP から開始されると、攻撃者がこの接続を使用してネットワーク制御をバイパスし、表示されていない内部リソースをスキャンまたは攻撃する可能性があります。

例 1: 次の例では、サーバーが接続している URL を攻撃者が制御できます。


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


攻撃者がネットワーク接続を乗っ取ることができるかどうかは、制御可能な URI の特定の部分と、接続を確立するために使用されるライブラリに応じて決まります。たとえば、URI スキーマの制御によって、攻撃者が次のように、httphttps とは異なるプロトコルを使用することが可能になります。

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

攻撃者は、この乗っ取ったネットワーク接続を利用して、次の攻撃を実行することがあります。

- イントラネット リソースのポート スキャン。
- ファイアウォールのバイパス。
- アプリケーション サーバーまたはイントラネット上で動作している脆弱なプログラムへの攻撃。
- Injection 攻撃または CSRF を使用した内部/外部 Web アプリケーションへの攻撃。
- file:// スキーマを使用したローカル ファイルへのアクセス。
- Windows システム上では、file:// スキーマおよび UNC パスによって攻撃者は内部共有をスキャンおよびアクセス可能。
- DNS キャッシュポイズニング攻撃の実行。

Abstract
アプリケーションは、リソース URI に対するユーザー制御のデータを使用して、サードパーティ製システムへのネットワーク接続を開始します。
Explanation
アプリケーション サーバーによるネットワーク接続に対して攻撃者が影響を及ぼす可能性がある場合、サーバー側のリクエスト フォージェリが発生します。ネットワーク接続がアプリケーション サーバーの内部 IP から開始されると、攻撃者がこの接続を使用してネットワーク制御をバイパスし、表示されていない内部リソースをスキャンまたは攻撃する可能性があります。

例 1: 次の例では、サーバーが接続している URL を攻撃者が制御できます。


string url = Request.Form["url"];
HttpClient client = new HttpClient();
HttpResponseMessage response = await client.GetAsync(url);


攻撃者がネットワーク接続を乗っ取ることができるかどうかは、制御可能な URI の特定の部分と、接続を確立するために使用されるライブラリに応じて決まります。たとえば、URI スキーマの制御によって、攻撃者が次のように、httphttps とは異なるプロトコルを使用することが可能になります。

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

攻撃者は、この乗っ取ったネットワーク接続を利用して、次の攻撃を実行することがあります。

- イントラネット リソースのポート スキャン。
- ファイアウォールのバイパス。
- アプリケーション サーバーまたはイントラネット上で動作している脆弱なプログラムへの攻撃。
- Injection 攻撃または CSRF を使用した内部/外部 Web アプリケーションへの攻撃。
- file:// スキーマを使用したローカル ファイルへのアクセス。
- Windows システム上では、file:// スキーマおよび UNC パスによって攻撃者は内部共有をスキャンおよびアクセス可能。
- DNS キャッシュ ポイズニング攻撃の実行。

Abstract
アプリケーションは、リソース URI に対するユーザー制御のデータを使用して、サードパーティ製システムへのネットワーク接続を開始します。
Explanation
アプリケーション サーバーによるネットワーク接続に対して攻撃者が影響を及ぼす可能性がある場合、Server-Side Request Forgery が発生します。ネットワーク接続がアプリケーション サーバーの内部 IP アドレスから開始されると、攻撃者がこの接続を使用してネットワーク制御をバイパスし、表示されていない内部リソースをスキャンまたは攻撃する可能性があります。

例 1: 次の例では、サーバーが接続している URL を攻撃者が制御できます。


url := request.Form.Get("url")
res, err =: http.Get(url)
...


攻撃者がネットワーク接続を乗っ取ることができるかどうかは、制御可能な URI の特定の部分と、接続を確立するために使用されるライブラリに応じて決まります。たとえば、URI スキームを制御する攻撃者には、httphttps とは異なる次のようなプロトコルを使用することが可能になります。

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

攻撃者は、この乗っ取ったネットワーク接続を利用して、次の攻撃を実行することがあります。

Abstract
アプリケーションは、リソース URI に対するユーザー制御のデータを使用して、サードパーティ製システムへのネットワーク接続を開始します。
Explanation
アプリケーション サーバーによるネットワーク接続に対して攻撃者が影響を及ぼす可能性がある場合、サーバー側のリクエスト フォージェリが発生します。ネットワーク接続がアプリケーション サーバーの内部 IP から開始されると、攻撃者がこの接続を使用してネットワーク制御をバイパスし、表示されていない内部リソースをスキャンまたは攻撃する可能性があります。

例 1: 次の例では、サーバーが接続している URL を攻撃者が制御できます。


String url = request.getParameter("url");
CloseableHttpClient httpclient = HttpClients.createDefault();
HttpGet httpGet = new HttpGet(url);
CloseableHttpResponse response1 = httpclient.execute(httpGet);


攻撃者がネットワーク接続を乗っ取ることができるかどうかは、制御可能な URI の特定の部分と、接続を確立するために使用されるライブラリに応じて決まります。たとえば、URI スキーマの制御によって、攻撃者が次のように、httphttps とは異なるプロトコルを使用することが可能になります。

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

攻撃者は、この乗っ取ったネットワーク接続を利用して、次の攻撃を実行することがあります。

- イントラネット リソースのポート スキャン。
- ファイアウォールのバイパス。
- アプリケーション サーバーまたはイントラネット上で動作している脆弱なプログラムへの攻撃。
- Injection 攻撃または CSRF を使用した内部/外部 Web アプリケーションへの攻撃。
- file:// スキーマを使用したローカル ファイルへのアクセス。
- Windows システム上では、file:// スキーマおよび UNC パスによって攻撃者は内部共有をスキャンおよびアクセス可能。
- DNS キャッシュ ポイズニング攻撃の実行。

Abstract
アプリケーションは、リソース URI に対するユーザー制御のデータを使用して、サードパーティ製システムへのネットワーク接続を開始します。
Explanation
アプリケーション サーバーによるネットワーク接続に対して攻撃者が影響を及ぼす可能性がある場合、Server-Side Request Forgery が発生します。ネットワーク接続がアプリケーション サーバーの内部 IP アドレスから開始されると、攻撃者がこの接続を使用してネットワーク制御をバイパスし、表示されていない内部リソースをスキャンまたは攻撃する可能性があります。

例 1: 次の例では、サーバーが接続している URL を攻撃者が制御できます。


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);
...


攻撃者がネットワーク接続を乗っ取ることができるかどうかは、制御可能な URI の特定の部分と、接続を確立するために使用されるライブラリに応じて決まります。たとえば、URI スキーマの制御によって、攻撃者が次のように、httphttps とは異なるプロトコルを使用することが可能になります。

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

攻撃者は、この乗っ取ったネットワーク接続を利用して、次の攻撃を実行することがあります。

- イントラネット リソースのポート スキャン。
- ファイアウォールのバイパス。
- アプリケーション サーバーまたはイントラネット上で動作している脆弱なプログラムへの攻撃。
- Injection 攻撃または CSRF を使用した内部/外部 Web アプリケーションへの攻撃。
- file:// スキーマを使用したローカル ファイルへのアクセス。
- Windows システム上では、file:// スキーマおよび UNC パスによって攻撃者は内部共有をスキャンおよびアクセス可能。
- DNS キャッシュ ポイズニング攻撃の実行。

Abstract
アプリケーションは、リソース URI に対するユーザー制御のデータを使用して、サードパーティ製システムへのネットワーク接続を開始します。
Explanation
アプリケーション サーバーによるネットワーク接続に対して攻撃者が影響を及ぼす可能性がある場合、サーバー側のリクエスト フォージェリが発生します。ネットワーク接続がアプリケーション サーバーの内部 IP アドレスから開始され、攻撃者がこの接続を使用して、ネットワーク制御をバイパスし、表示されていない内部リソースをスキャンまたは攻撃する可能性があります。

例 1: 次の例では、サーバーが接続している URL を攻撃者が制御できます。


$url = $_GET['url'];
$c = curl_init();
curl_setopt($c, CURLOPT_POST, 0);
curl_setopt($c,CURLOPT_URL,$url);
$response=curl_exec($c);
curl_close($c);


攻撃者がネットワーク接続を乗っ取ることができるかどうかは、制御可能な URI の特定の部分と、接続を確立するために使用されるライブラリに応じて決まります。たとえば、URI スキーマの制御によって、攻撃者が次のように、httphttps とは異なるプロトコルを使用することが可能になります。

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

攻撃者は、この乗っ取ったネットワーク接続を利用して、次の攻撃を実行することがあります。

- イントラネット リソースのポート スキャン。
- ファイアウォールのバイパス。
- アプリケーション サーバーまたはイントラネット上で動作している脆弱なプログラムへの攻撃。
- Injection 攻撃または CSRF を使用した内部/外部 Web アプリケーションへの攻撃。
- file:// スキーマを使用したローカル ファイルへのアクセス。
- Windows システム上では、file:// スキーマおよび UNC パスによって攻撃者は内部共有をスキャンおよびアクセス可能。
- DNS キャッシュ ポイズニング攻撃の実行。

Abstract
アプリケーションは、リソース URI に対するユーザー制御のデータを使用して、サードパーティ製システムへのネットワーク接続を開始します。
Explanation
アプリケーション サーバーによるネットワーク接続に対して攻撃者が影響を及ぼす可能性がある場合、サーバー側のリクエスト フォージェリが発生します。ネットワーク接続がアプリケーション サーバーの内部 IP アドレスから開始され、攻撃者がこの接続を使用して、ネットワーク制御をバイパスし、表示されていない内部リソースをスキャンまたは攻撃する可能性があります。

例 1: 次の例では、サーバーが接続している URL を攻撃者が制御できます。


def getFile(url: String) = Action { request =>
...
val url = request.body.asText.getOrElse("http://google.com")

ws.url(url).get().map { response =>
Ok(s"Request sent to $url")
}
...
}


攻撃者がネットワーク接続を乗っ取ることができるかどうかは、制御可能な URI の特定の部分と、接続を確立するために使用されるライブラリに応じて決まります。たとえば、URI スキーマの制御によって、攻撃者が次のように、httphttps とは異なるプロトコルを使用することが可能になります。

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

攻撃者は、この乗っ取ったネットワーク接続を利用して、次の攻撃を実行することがあります。

- イントラネット リソースのポート スキャン。
- ファイアウォールのバイパス。
- アプリケーション サーバーまたはイントラネット上で動作している脆弱なプログラムへの攻撃。
- Injection 攻撃または CSRF を使用した内部/外部 Web アプリケーションへの攻撃。

Abstract
ユーザー制御のデータはテンプレート エンジンのテンプレートとして使用され、攻撃者がテンプレート コンテキストにアクセスし、場合によっては任意のコードをアプリケーション サーバーに挿入して実行できるようになります。
Explanation
テンプレート エンジンは動的なデータを使用してコンテンツをレンダーするために使用されます。このコンテキスト データは通常、ユーザーによって制御され、テンプレートによって書式設定されて、Web ページ、電子メールなどが生成されます。テンプレート エンジンでは、コンテキスト データを条件文、ループなどのコード構造で処理することで、動的コンテンツをレンダーするための強力な言語表現をテンプレートで使用できます。攻撃者がテンプレートを制御してレンダーできる場合、式を挿入してコンテキスト データを開示したり、サーバーで任意のコマンドを実行することさえできます。

例 1: 次の例は、テンプレートを HTTP リクエストから取得してレンダリングする方法を示しています。

// 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 1 では Velocity をテンプレート エンジンとして使用しています。そのエンジンでは、攻撃者は次のテンプレートを送信してサーバー上で任意のコマンドを実行できます。

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

例 1: 次の例は、テンプレートを HTTP リクエストから取得し、Jinja2 テンプレート エンジンを使用してレンダーする方法を示しています。

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 1 では Jinja2 をテンプレート エンジンとして使用しています。そのエンジンでは、攻撃者は次のテンプレートを送信してサーバーから任意のファイルを読み取ることができます。

template={{''.__class__.__mro__[2].__subclasses__()[40]('/etc/passwd').read()}}
例 2: 次の例は、テンプレートを HTTP リクエストから取得し、Django テンプレート エンジンを使用してレンダーする方法を示しています。

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 2 では Django をテンプレート エンジンとして使用しています。そのエンジンでは、攻撃者は任意のコマンドを実行できませんが、テンプレート コンテキストにあるすべてのオブジェクトにアクセスできます。この例では、シークレット トークンをコンテキストで入手できるため、攻撃者によって漏洩される可能性があります。

Abstract
既存のセッション ID がある場合でもそれを無効にせずにユーザーを認証すると、認証済みのセッションを盗む機会を攻撃者に与えることになります。
Explanation
次の場合に Session Fixation の脆弱性が発生します。

1.Web アプリケーションが、既存のセッションを無効にしないでユーザーを認証し、すでにユーザーと関連付けられているセッションを引き続き使用する場合。
2.攻撃者がユーザーに既知のセッション ID を強制的に使用させることができる場合に、このユーザーが認証されると、攻撃者は認証済みセッションにアクセスできます。

Session Fixation の脆弱性の一般的な悪用では、攻撃者は Web アプリケーション上に新しいセッションを作成し、関連したセッション ID を記録します。次に攻撃者はそのセッション ID を使用してサーバーに攻撃対象を認証させ、アクティブなセッションの間、ユーザーのアカウントに攻撃者がアクセスできるようにします。

Spring Security など、新しいセッションの作成時に既存のセッションを自動で無効にするフレームワークもあります。この動作は無効化できますが、アプリケーションはこの攻撃に対して脆弱になります。

例 1: 次の例に示す Spring Security で保護されるアプリケーションのスニペットでは、セッション ID 固定化対策が無効化されています。


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


アプリケーションが脆弱であっても、ここで説明する特定の攻撃が成功するかどうかは、監視されていない公共端末へのアクセス、危険に晒されているセッションをアクティブにする能力、公共端末上の脆弱なアプリケーションへのログオンを行う被害者のような、攻撃者に有利に働く数々の要因によります。多くの場合、最初の 2 つの問題は時間をかければ克服できます。公共の端末を使用し、また脆弱なアプリケーションにログインしようとする攻撃対象を発見することも、サイトの認知度が適度に高ければ可能です。サイトがあまり知られていない場合は、公共の端末を使用してアクセスする攻撃対象を発見する確率も、前述した攻撃手段の成功の確率も、それだけ低くなります。

Session Fixation の脆弱性を悪用する際に攻撃者が直面する最大の課題は、攻撃者に既知のセッション ID を使用して脆弱なアプリケーションの認証を受けるように仕向けることです。Example 1 では、攻撃者は明らかに直接的な方法を使用しており、あまり知られていない Web サイトまでには攻撃の手を広げていません。ただし、安心は禁物です。攻撃者はこの攻撃手段の限界をバイパスするための七つ道具を持っています。攻撃者が最も一般的に使用するテクニックは、ターゲット サイトにある Cross-Site Scripting や HTTP レスポンス スプリッティングといった脆弱性を利用することです [1]。攻撃者は攻撃対象を操作して、JavaScript などのコードを攻撃対象のブラウザーに反映するなど悪意あるリクエストを脆弱なアプリケーションに送信するように仕向けて cookie を作成し、攻撃者の支配下にあるセッション ID を再使用させることができます。

指定された URL に関連する最上位のドメインに cookie が関連付けられることが多いため、注意が必要です。bank.example.comrecipes.example.com のように、多数のアプリケーションが同一の最上位ドメインに存在する場合、1 つのアプリケーションに脆弱性があると、攻撃者はセッション ID が固定化された cookie を設定して、ドメイン example.com 上のあらゆるアプリケーションとの間のすべての通信で使用されるようにできます [2]。

他の攻撃手段には、DNS ポイズニングおよび関連したネットワークベースの攻撃があります。この攻撃では、攻撃者は適正なサイトへのリクエストをリダイレクトすることによって、悪意あるサイトにユーザーを誘い込みます。ネットワークベースの攻撃は一般的に、被害者のネットワーク上に物理的に存在することや、ネットワーク上の危険性のあるマシンを制御することで行われます。リモートから攻撃することはより難しくなりますが、重大さを見過ごすわけにはいきません。Apache Tomcatのデフォルト実装などの、それほど安全でないセッション管理メカニズムでは、通常 cookie にあるとされるセッション ID を URL で指定されることも許容されます。この場合、攻撃者は攻撃対象に悪意あるURLを電子メールで送信するだけで、固定されたセッションIDを使用させることができます。

desc.structural.php.session_fixation
Abstract
攻撃者は、アプリケーション ロジックの悪用につながる Spring セッションの属性を修正できます。
Explanation
@SessionAttributes のアノテーションが付けられているクラスは、Spring がセッション オブジェクトのモデル属性への変更を複製することを意味します。攻撃者が任意の値をモデル属性内に格納できる場合、変更は、その変更がアプリケーションにより信頼されるセッション オブジェクトに複製されます。そのセッション属性が、ユーザーが修正できないはずの信頼できるデータにより初期化される場合、攻撃者は、セッションを混乱させる攻撃を実行してアプリケーションのロジックを悪用できる可能性があります。

例 1: 次のコントローラーは、ログインの成功と同時にユーザー データをセッションにロードするメソッドを保有しています。


@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";
}
}
...
}


別のコントローラーは、パスワードのリセット機能を取り扱います。クラスに @SessionAttributes("user") のアノテーションが付けられているため、User インスタンスのセッションからのロードを試み、パスワードの質問のリセットの確認に使用します。


@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
...
}
}
}


開発者には、user インスタンスを、ログイン処理中それが格納されているセッションからロードする意図がありました。ただし、Spring は、リクエストを確認し、データのモデル user インスタンスへのバインドを試みます。受信したリクエストに、User クラスに紐付けることができるデータが含まれている場合、Spring により受信データがユーザー セッションの属性にマージされます。このシナリオは、answerReset クエリ パラメーターの任意の回答および同値を送信し、セッションに格納された値を上書きすることで、悪用できます。このようにして、攻撃者は、不特定多数のユーザーに対して任意の新しいパスワードを設定できます。

Abstract
システム設定の外部制御を許可すると、サービスの妨害や、想定外の動作がアプリケーションで発生する原因となることがあります。
Explanation
攻撃者がシステムの動作を決定する値を制御できるか、特定のリソースを管理できるか、または何らかの方法でアプリケーションの機能に影響を与えることができる場合、Setting Manipulation の脆弱性が発生します。



Setting Manipulation はさまざまな関数を対象としているため、どのような方法で説明しようとしても不完全になります。Setting Manipulation カテゴリに対処する関数間に緊密な関係を見つけようとするよりも、攻撃者に制御を許してはならないシステム値の種類を検討してください。

例 1: 次の PHP コード スニペットは、HTTP リクエストからパラメーターを読み取り、サービス データベース接続として設定します。


...
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.


この例では、攻撃者は ABAP DBCON テーブルで存在しないデータベース接続を指定するか、データベースの不正な部分に接続することでエラーを発生させます。

一般的に、ユーザー入力などの信頼できないデータを使用して機密データを管理できないようにします。攻撃者がこれらの値を制御することによって手に入れる能力は、いつでも議論の余地なく明白であるというわけではありませんが、攻撃者の創造力を過小評価してはいけません。

Setting Manipulation はさまざまな関数を対象としているため、どのような方法で説明しようとしても不完全になります。Setting Manipulation カテゴリに対処する関数間に緊密な関係を見つけようとするよりも、攻撃者に制御を許すべきではないシステム値の種類を検討してください。

例 1: 次の C 言語のコード例では、コマンドラインのパラメーターの 1 つとして数字を受け取り、使用中マシンのホスト ID に代入しています。


...
sethostid(argv[1]);
...
sethostid() を適切に呼び出すためにはプロセスを権限付きで実行することが必要ですが、権限を所有しないユーザーがこのプログラムを呼び出すことが可能な場合もあります。このコード例では、入力により直接システム設定値を制御することをユーザーに許可しています。攻撃者がホスト ID に悪意のある値を代入すると、ネットワーク上で影響を受けたマシンの識別が不能になる、または意図しない動作を引き起こす原因となります。

一般的に、ユーザー入力などの信頼できないデータを使用して機密データを管理できないようにします。攻撃者がこれらの値を制御することによって手に入れる能力は、いつでも議論の余地なく明白であるというわけではありませんが、攻撃者の創造力を過小評価してはいけません。

Abstract
システム設定の外部制御を許可すると、サービスの妨害や、想定外の動作がアプリケーションで発生する原因となることがあります。
Explanation
攻撃者がシステムの動作を決定する値を制御できるか、特定のリソースを管理できるか、または何らかの方法でアプリケーションの機能に影響を与えることができる場合、Setting Manipulation の脆弱性が発生します。



Setting Manipulation はさまざまな関数を対象としているため、どのような方法で説明しようとしても不完全になります。Setting Manipulation カテゴリに対処する関数間に緊密な関係を見つけようとするよりも、攻撃者に制御を許すべきではないシステム値の種類を検討してください。

例 1: 次の COBOL コード部分は、ターミナルから値を読み取って、キュー オブジェクトへのアクセスを確立するために使用されるオプションの計算にその値を使用しています。


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


この例では、攻撃者はキューに排他的にアクセスするのではなく、キューの共有を許可するようにオプションを指定することが可能です。

一般的に、ユーザー入力などの信頼できないデータを使用して機密データを管理できないようにします。攻撃者がこれらの値を制御することによって手に入れる能力は、いつでも議論の余地なく明白であるというわけではありませんが、攻撃者の創造力を過小評価してはいけません。

例 1: 次のコードは Web フォームから数値を読み取り、読み取った値を使用して初期化ファイルのタイムアウト値を設定します。


...
<cfset code = SetProfileString(IniPath,
Section, "timeout", Form.newTimeout)>
...
Form.newTimeout の値は、タイムアウトの指定に使用されます。そのため、攻撃者は非常に大きい数値を指定することで、アプリケーションに対して Denial of Service (DoS) 攻撃を仕掛けることが可能となる場合があります。

Abstract
システム設定の外部制御を許可すると、サービスの妨害や、想定外の動作がアプリケーションで発生する原因となることがあります。
Explanation
攻撃者がシステムの動作を決定する値を制御できるか、特定のリソースを管理できるか、または何らかの方法でアプリケーションの機能に影響を与えることができる場合、Setting Manipulation の脆弱性が発生します。



Setting Manipulation はさまざまな関数を対象としているため、どのような方法で説明しようとしても不完全になります。Setting Manipulation カテゴリに対処する関数間に緊密な関係を見つけようとするよりも、攻撃者に制御を許すべきではないシステム値の種類を検討してください。

例 1: 次の Node.js コード スニペットは、http.IncomingMessage 要求変数から文字列を読み取り、追加の V8 コマンド行フラグを設定するためにそれを使用します。


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


この例では、攻撃者は VM にさまざまなフラグを設定できるようになり、プログラムのクラッシュ、潜在的なデータ損失を含む予測不能な動作が引き起こされる可能性があります。

一般的に、ユーザー入力などの信頼できないデータを使用して機密データを管理できないようにします。攻撃者がこれらの値を制御することによって手に入れる能力は、いつでも議論の余地なく明白であるというわけではありませんが、攻撃者の創造力を過小評価してはいけません。

攻撃者がシステムの動作を決定する値を制御できるか、特定のリソースを管理できるか、または何らかの方法でアプリケーションの機能に影響を与えることができる場合、Setting Manipulation の脆弱性が発生します。

Setting Manipulation はさまざまな関数を対象としているため、どのような方法で説明しようとしても不完全になります。Setting Manipulation カテゴリに対処する関数間に緊密な関係を見つけようとするよりも、攻撃者に制御を許すべきではないシステム値の種類を検討してください。

例 1: 次のコードは SQL ログ ハンドラを設定し、ユーザーが制御できる値を使用します。


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


一般的に、ユーザー入力などの信頼できないデータを使用して機密データを管理できないようにします。攻撃者がこれらの値を制御することによって手に入れる能力は、いつでも議論の余地なく明白であるというわけではありませんが、攻撃者の創造力を過小評価してはいけません。

Abstract
システム設定の外部制御を許可すると、サービスの妨害や、想定外の動作がアプリケーションで発生する原因となることがあります。
Explanation
攻撃者がシステムの動作を決定する値を制御できるか、特定のリソースを管理できるか、または何らかの方法でアプリケーションの機能に影響を与えることができる場合、Setting Manipulation の脆弱性が発生します。



Setting Manipulation はさまざまな関数を対象としているため、どのような方法で説明しようとしても不完全になります。Setting Manipulation カテゴリに対処する関数間に緊密な関係を見つけようとするよりも、攻撃者に制御を許すべきではないシステム値の種類を検討してください。

例 1: 次の VB コード の部分は Request オブジェクトから文字列を読み取り、データベース Connection のアクティブなカタログに設定します。


...
Dim conn As ADODB.Connection
Set conn = New ADODB.Connection
Dim rsTables As ADODB.Recordset
Dim Catalog As New ADOX.Catalog
Set Catalog.ActiveConnection = conn
Catalog.Create Request.Form("catalog")
...


この例では、攻撃者は存在しないカタログ名を提供するか、データベースの不正な部分に接続することでエラーを発生させます。

一般的に、ユーザー入力などの信頼できないデータを使用して機密データを管理できないようにします。攻撃者がこれらの値を制御することによって手に入れる能力は、いつでも議論の余地なく明白であるというわけではありませんが、攻撃者の創造力を過小評価してはいけません。

Abstract
ユーザー制御 Bean 定義リソースをロードすると、攻撃者によるサーバーでの任意のコードの実行、アプリケーション ロジックの悪用、サービス拒否の原因になります。
Explanation
開発有効は、Spring により、Bean 定義をローカル ファイルやリモート URL を含む複数のリソースからロードできます。攻撃者は、Bean 定義リソースのコンテンツを制御できる場合は、初期化時の任意コードの実行を可能にする悪意のある Bean 定義を注入できます。

: 次の例では、Bean 定義リソースをユーザーが制御している場所からロードします。

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

Abstract
Spring Boot アプリケーションは、認証を必要としない Actuator エンドポイントを使用します。
Explanation
Spring Boot アプリケーションは、アプリケーションのさまざまな側面を監視するための REST エンドポイントである Actuator をデプロイするように設定できます。機密データを公開する可能性がある各種の組み込み Actuator があり、それらは "機密" であることがわかるラベルが付いています。デフォルトでは、機密性の高いすべての HTTP エンドポイントは、ACTUATOR ロールを持つユーザーのみにアクセスを許可することで保護されています。

このアプリケーションは、機密性の高いエンドポイントの認証要件を無効にしています。

例 1:


management.security.enabled=false


または、機密性の高いエンドポイントを機密性が高くないものとしてマークしています。

例 2:


endpoints.health.sensitive=false


または、カスタムの Actuator が、機密性が高くないものとして設定されています。


@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
...
}
}
