界: Security Features

ソフトウェアのセキュリティは、セキュリティ ソフトウェアではありません。ここでは、認証、アクセス制御、機密性、暗号化、権限管理などのトピックについて説明します。

Access Control: Database

Abstract
適切な Access Control がない場合、ユーザーの制御下にある主キーを含む SQL ステートメントを実行すると、攻撃者は権限のないレコードを見ることができます。
Explanation
データベースの Access Control エラー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. SQL クエリで主キーの値を特定するためにデータが使用されている場合。
例 1: 次のコードは、整数に依存するため、SQL Injection の脆弱性に対して脆弱ではないステートメントを使用して、指定された識別子と一致する領収書を検索する SQL クエリを作成し、実行します [1]。識別子は、現在の認証されたユーザーに関連付けられているすべての領収書のリストから選択されています。


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.
...


問題は、開発者が ID に可能なすべての値を検討しきれていないことです。現在のユーザーに属する領収書 ID のリストがインターフェイスにより生成されますが、攻撃者はこのインターフェイスを回避して目的の領収書をリクエストする可能性があります。この例のコードの場合、リクエストされた領収書へのアクセス権限をユーザーが確保しているか確認しないため、現在のユーザーに帰属していなくても、リクエストされたとおりの領収書を表示します。

データベースの Access Control エラー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。

例 1: 次のコードは、メタ文字をエスケープして SQL Injection の脆弱性を阻止するパラメーター化されたステートメントを使用して、指定された識別子と一致する領収書を検索する SQL クエリを作成し、実行します [1]。識別子は、現在の認証されたユーザーに関連付けられているすべての領収書のリストから選択されています。


...
var params:Object = LoaderInfo(this.root.loaderInfo).parameters;

Abstract
適切な Access Control がない場合、ユーザー指定の主キーが含まれている可能性のある SOQL/SOSL ステートメントを実行すると、攻撃者は権限のないレコードを見ることができます。
Explanation
データベースの Access Control エラー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. SOQL/SOSL クエリで主キーの値を特定するためにデータが使用されている場合。
例 1: 次のコード例では、inputID 値は事前定義されたリストから取得されていて、バインド変数は SOQL/SOSL Injection を防止するのに役立ちます。


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


上記の例で問題となるのは、事前定義された ID リストを使用するだけでは、ユーザーによる inputID の値の変更を防止するには不十分なことです。攻撃者がインターフェイスをバイパスし、別の値を使用してリクエストを送信できる場合は、他の連絡先情報にアクセスできてしまいます。この例のコードの場合、リクエストされた連絡先へのアクセス権限がユーザーにあるか確認しないため、ユーザーがこの連絡先を表示する権限がない場合でも、すべての連絡先が表示されます。

Abstract
適切な Access Control がない場合、ユーザーの制御下にある主キーを含む SQL ステートメントを実行すると、攻撃者は権限のないレコードを見ることができます。
Explanation
データベースの Access Control エラー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. SQL クエリで主キーの値を特定するためにデータが使用されている場合。
例 1: 次のコードは、メタ文字をエスケープして SQL Injection の脆弱性を阻止するパラメーター化されたステートメントを使用して、指定された識別子と一致する領収書を検索する SQL クエリを作成し、実行します [1]。識別子は、現在の認証されたユーザーに関連付けられているすべての領収書のリストから選択されています。


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


問題は、開発者が id に可能なすべての値を検討しきれていないことです。現在のユーザーに属する領収書 ID のリストがインターフェイスにより生成されますが、攻撃者はこのインターフェイスを回避して目的の領収書をリクエストする可能性があります。この例のコードの場合、リクエストされた領収書へのアクセス権限をユーザーが確保しているか確認しないため、現在のユーザーに帰属していなくても、リクエストされたとおりの領収書を表示します。

Abstract
適切な Access Control がない場合、ユーザーの制御下にある主キーを含む SQL ステートメントを実行すると、攻撃者は権限のないレコードにアクセスできるようになります。
Explanation
データベースの Access Control エラー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力された場合。


2.SQL クエリで主キーの値を特定するためにデータが使用されている場合。
例 1: 次のコードは、メタ文字をエスケープして SQL Injection の脆弱性を阻止するパラメーター化されたステートメントを使用して、指定された識別子と一致する領収書を検索する SQL クエリを作成し、実行します [1]。識別子は、現在の認証されたユーザーに関連付けられているすべての領収書のリストから選択されています。


...
id := request.FormValue("invoiceID")
query := "SELECT * FROM invoices WHERE id = ?";
rows, err := db.Query(query, id)
...


問題は、開発者が id に可能なすべての値を検討しきれていないことです。現在のユーザーに属する領収書 ID のリストがインターフェイスにより生成されますが、攻撃者はこのインターフェイスを回避して目的の領収書をリクエストする可能性があります。この例のコードの場合、リクエストされた領収書へのアクセス権限をユーザーが確保しているか確認しないため、現在のユーザーに帰属していなくても、リクエストされたとおりの領収書を表示します。

Abstract
適切な Access Control がない場合、ユーザーの制御下にある主キーを含む SQL ステートメントを実行すると、攻撃者は権限のないレコードを見ることができます。
Explanation
データベースの Access Control エラー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. SQL クエリで主キーの値を特定するためにデータが使用されている場合。
例 1: 次のコードは、メタ文字をエスケープして SQL Injection の脆弱性を阻止するパラメーター化されたステートメントを使用して、指定された識別子と一致する領収書を検索する SQL クエリを作成し、実行します [1]。識別子は、現在の認証されたユーザーに関連付けられているすべての領収書のリストから選択されています。


...
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();
...


問題は、開発者が id に可能なすべての値を検討しきれていないことです。現在のユーザーに属する領収書 ID のリストがインターフェイスにより生成されますが、攻撃者はこのインターフェイスを回避して目的の領収書をリクエストする可能性があります。この例のコードの場合、リクエストされた領収書へのアクセス権限をユーザーが確保しているか確認しないため、現在のユーザーに帰属していなくても、リクエストされたとおりの領収書を表示します。

一部には、モバイルの世界ではデータベースの Access Control エラーのような古典的な Web アプリケーションの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。

例 2: 次のコードでは、Android プラットフォームにExample 1 を応用しています。


...
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});
...


最新の Web フレームワークの多くが、ユーザー入力を検証するためのメカニズム (Struts および Struts 2 を含む) を提供しています。検証されていない入力ソースの問題を正確に反映させるために、Fortify セキュア コーディング ルールパックは、フレームワーク検証メカニズムが使用されている場合には、その証拠を示し、悪用の可能性を低く見積もり、Fortify Static Code Analyzer により報告される問題の優先度を動的に変更します。この機能は、状況依存ランキングと呼ばれます。Fortify ユーザーがさらに監査プロセスを効果的に進めることができるように、Fortify Software Security Research グループでは、入力ソースに適用される検証メカニズムを基準としたフォルダに問題をグループ化する Data Validation (データ検証) プロジェクト テンプレートのフォルダを用意しています。

問題は、開発者が id に可能なすべての値を検討しきれていないことです。現在のユーザーに属する領収書 ID のリストがインターフェイスにより生成されますが、攻撃者はこのインターフェイスを回避して目的の領収書をリクエストする可能性があります。この例のコードの場合、リクエストされた領収書へのアクセス権限をユーザーが確保しているか確認しないため、現在のユーザーに帰属していなくても、リクエストされたとおりの領収書を表示します。

Abstract
適切な Access Control がない場合、ユーザーの制御下にある主キーを含む SQL ステートメントを実行すると、攻撃者は権限のないレコードを見ることができます。
Explanation
データベースの Access Control エラー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. SQL クエリで主キーの値を特定するためにデータが使用されている場合。
例 1: 次のコードは、メタ文字をエスケープして SQL Injection の脆弱性を阻止するパラメーター化されたステートメントを使用して、指定された識別子と一致する領収書を検索する SQL クエリを作成し、実行します [1]。識別子は、現在の認証されたユーザーに関連付けられているすべての領収書のリストから選択されています。


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


問題は、開発者が id に可能なすべての値を検討しきれていないことです。現在のユーザーに属する領収書 ID のリストがインターフェイスにより生成されますが、攻撃者はこのインターフェイスを回避して目的の領収書をリクエストする可能性があります。この例のコードの場合、リクエストされた領収書へのアクセス権限をユーザーが確保しているか確認しないため、現在のユーザーに帰属していなくても、リクエストされたとおりの領収書を表示します。

最新の Web フレームワークの多くが、ユーザー入力を検証するためのメカニズム (Struts および Struts 2 を含む) を提供しています。検証されていない入力ソースの問題を正確に反映させるために、Fortify セキュア コーディング ルールパックは、フレームワーク検証メカニズムが使用されている場合には、その証拠を示し、悪用の可能性を低く見積もり、Fortify Static Code Analyzer により報告される問題の優先度を動的に変更します。この機能は、状況依存ランキングと呼ばれます。Fortify ユーザーがさらに監査プロセスを効果的に進めることができるように、Fortify Software Security Research グループでは、入力ソースに適用される検証メカニズムを基準としたフォルダに問題をグループ化する Data Validation (データ検証) プロジェクト テンプレートのフォルダを用意しています。

Abstract
適切な Access Control がない場合、ユーザーの制御下にある主キーを含む SQL ステートメントを実行すると、攻撃者は権限のないレコードを見ることができます。
Explanation
データベースの Access Control エラー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. SQL クエリで主キーの値を特定するためにデータが使用されている場合。
例 1: 次のコードは、メタ文字をエスケープして SQL Injection の脆弱性を阻止するパラメーター化されたステートメントを使用して、指定された識別子と一致する領収書を検索する SQL クエリを作成し、実行します [1]。識別子は、現在の認証されたユーザーに関連付けられているすべての領収書のリストから選択されています。


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


問題は、開発者が id に可能なすべての値を検討しきれていないことです。現在のユーザーに属する領収書 ID のリストがインターフェイスにより生成されますが、攻撃者はこのインターフェイスを回避して目的の領収書をリクエストする可能性があります。この例のコードの場合、リクエストされた領収書へのアクセス権限をユーザーが確保しているか確認しないため、現在のユーザーに帰属していなくても、リクエストされたとおりの領収書を表示します。

Abstract
適切な Access Control がない場合、ユーザーの制御下にある主キーを含む SQL ステートメントを実行すると、攻撃者は権限のないレコードを見ることができます。
Explanation
データベースの Access Control エラー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. SQL クエリで主キーの値を特定するためにデータが使用されている場合。
例 1: 次のコードは、メタ文字をエスケープして SQL Injection の脆弱性を阻止するパラメーター化されたステートメントを使用して、指定された識別子と一致する領収書を検索する SQL クエリを作成し、実行します [1]。識別子は、現在の認証されたユーザーに関連付けられているすべての領収書のリストから選択されています。


...
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
...



問題は、開発者が id に可能なすべての値を検討しきれていないことです。現在のユーザーに属する領収書 ID のリストがインターフェイスにより生成されますが、攻撃者はこのインターフェイスを回避して目的の領収書をリクエストする可能性があります。この例のコードの場合、リクエストされた領収書へのアクセス権限をユーザーが確保しているか確認しないため、現在のユーザーに帰属していなくても、リクエストされたとおりの領収書を表示します。
