Abstract
プログラムが、セッション cookie に SameSite 属性を設定できません。
Explanation
ブラウザーは、cookie を設定しているサイトに対して行われたあらゆる HTTP リクエストに自動的に cookie を追加します。cookie は、セッション ID や認証トークン、またはセッション中に同じサイトに対して行われる別のリクエスト間で共有されるサイト データなどの機密データを保存する場合があります。攻撃者は、ブラウザが自動的にクッキーをリクエストに追加するため、クライアントマシンに読み込まれたサードパーティのサイト ページから認証サイトへのリクエストを生成することで、なりすまし攻撃を行うことができます。

SameSite パラメーターは、リクエストがファーストパーティまたは同じサイトのコンテキストから生成された場合にのみリクエストに追加するよう cookie の範囲を制限します。これは、Cross-Site Request Forgery (CSRF) 攻撃から cookie を保護するのに役立ちます。SameSite パラメーターの値は、次の 3 つのうちのいずれかになります。

- Strict: Strict に設定した場合、cookie はトップレベル ナビゲーションのリクエストとともにのみ送信されます。
- Lax: Lax に設定した場合、cookie は、同じホストからのトップレベル ナビゲーションだけでなく、サードパーティ サイトからホストへの GET リクエストとともに送信されます。たとえば、ホスト サイトにリンクする、iframe タグか href タグを持つサードパーティ サイトがあるとします。ユーザーがリンクをたどると、リクエストには cookie が含まれます。
- None: Cookie は、Cookie に設定されたパスやドメインの範囲内にあるサイトに対して行われたすべてのリクエストで送信されます。POST メソッドを使用したフォームの送信により生成されたリクエストも、リクエストとともに Cookie を送信することができます。

例 1: 次のコードは、セッション cookie の SameSite 属性を None に設定しています。

...
Cookie cookie = new Cookie('name', 'Foo', path, -1, true, 'None');

Abstract
プログラムは、セッション cookie で SameSite 属性の設定に失敗します。
Explanation
ブラウザーは、cookie を設定しているサイトに対して行われたあらゆる HTTP リクエストに自動的に cookie を追加します。cookie は、セッション ID や認証トークン、またはセッション中に同じサイトに対して行われる別のリクエスト間で共有されるサイト データなどの機密データを保存する場合があります。攻撃者は、ブラウザーが自動的に Cookie をリクエストに追加するため、クライアント マシンに読み込まれたサードパーティのサイト ページから認証サイトへのリクエストを生成することで、なりすまし攻撃を行うことができます。

SameSite 属性は、リクエストがファーストパーティまたは同じサイトのコンテキストから生成された場合にのみリクエストに追加するよう Cookie の範囲を制限します。これは、Cross-Site Request Forgery (CSRF) 攻撃から cookie を保護するのに役立ちます。SameSite 属性の値は、次の 3 つのうちのいずれかになります。

- Strict: Strict に設定した場合、cookie はトップレベル ナビゲーションのリクエストとともにのみ送信されます。
- Lax: Lax に設定した場合、Cookie は、同じホストからのトップレベル ナビゲーションだけでなく、サードパーティ サイトからの GET リクエスト (ホスト サイトにリンクする iframe タグまたは href タグを持つリクエストを含む) とともに送信されます。たとえば、ホスト サイトにリンクする、iframe タグか href タグを持つサードパーティ サイトがあるとします。ユーザーがリンクをたどると、リクエストには cookie が含まれます。
- None: Cookie は、Cookie に設定されたパスやドメインの範囲内にあるサイトに対して行われたすべてのリクエストで送信されます。POST メソッドを使用したフォームの送信により生成されたリクエストも、リクエストとともに Cookie を送信することができます。

例 1: 次のコードでは、セッション cookie の SameSite 属性を無効にしています。

app.get('/', function (req, res) {
...
res.cookie('name', 'Foo', { sameSite: false });
...
}

desc.structural.python.cookie_security_missing_samesite_attribute
Abstract
cookie のドメインがあまりに広範にわたっていると、別のアプリケーションを介し攻撃を受ける可能性があります。
Explanation
開発者は ".example.com" などのベース ドメインにわたってアクティブになるように cookie を設定する傾向にあります。 この方法では同じベースドメインおよびサブドメイン上にあるすべての Web アプリケーションがその cookie にアクセスできてしまいます。 cookie にはセッション ID などの重要な情報が保存されていることが多いため、アプリケーション間で cookie を共有すると、1 個のアプリケーションの脆弱性が別のアプリケーションに影響を及ぼす可能性があります。

例 1:http://secure.example.com/ に安全なアプリケーションを配置していると考えてみましょう。このアプリケーションでは、ユーザーがログインすると、ドメインが「.example.com」であるセッション ID の cookie が設定されます。

例:

HttpCookie cookie = new HttpCookie("sessionID", sessionID);
cookie.Domain = ".example.com";


安全性の劣る別のアプリケーションが http://insecure.example.com/ に配置されていて、このアプリケーションにクロスサイト スクリプティングの脆弱性が存在するとします。 http://secure.example.com に認証されているユーザーが http://insecure.example.com にアクセスすると、http://secure.example.com から送信されるセッション cookie が漏洩する可能性があります。

cookie の読み取りに加えて、Cookie Poisoning 攻撃が実行される可能性もあります。その場合、攻撃者は insecure.example.com を使用してパスが広範にわたる cookie を独自に作成し、secure.example.com から送信される cookie を上書きします。

Abstract
cookie のドメインがあまりに広範にわたっていると、別のアプリケーションを介し攻撃を受ける可能性があります。
Explanation
開発者は ".example.com" などのベース ドメインにわたってアクティブになるように cookie を設定する傾向にあります。 この方法では同じベースドメインおよびサブドメイン上にあるすべての Web アプリケーションがその cookie にアクセスできてしまいます。 cookie にはセッション ID などの重要な情報が保存されていることが多いため、アプリケーション間で cookie を共有すると、1 個のアプリケーションの脆弱性が別のアプリケーションに影響を及ぼす可能性があります。

例 1:http://secure.example.com/ に安全なアプリケーションを配置していると考えてみましょう。このアプリケーションでは、ユーザーがログインすると、ドメインが「.example.com」であるセッション ID の cookie が設定されます。

例:

...
NSDictionary *cookieProperties = [NSDictionary dictionary];
...
[cookieProperties setValue:@".example.com" forKey:NSHTTPCookieDomain];
...
NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
...


安全性の劣る別のアプリケーションが http://insecure.example.com/ に配置されていて、このアプリケーションに Cross-Site Scripting の脆弱性が存在するとします。http://secure.example.com に認証されているユーザーが http://insecure.example.com にアクセスすると、http://secure.example.com から送信されるセッション cookie が漏洩する可能性があります。

cookie の読み取りに加えて、Cookie Poisoning 攻撃が実行される可能性もあります。その場合、攻撃者は insecure.example.com を使用してパスが広範にわたる cookie を独自に作成し、secure.example.com から送信される cookie を上書きします。

Abstract
cookie のパスがあまりに広範にわたっていると、同じドメイン上の別のアプリケーションを介してアクセスされることがあります。
Explanation
開発者は cookie を root コンテキストパス ("/") からアクセスできるように設定する傾向にあります。この方法ではドメイン名を同じくするすべての Web アプリケーションがその cookie にアクセスできてしまいます。cookie にはセッション ID などの重要な情報が保存されていることが多いため、アプリケーション間で cookie を共有すると、1 個のアプリケーションの脆弱性が別のアプリケーションに影響を及ぼす可能性があります。

例 1:http://communitypages.example.com/MyForum にフォーラム アプリケーションを配置している例を考えてみましょう。このアプリケーションでは、ユーザーがフォーラムにログインすると、"/" というパスを持つセッション ID の cookie が設定されます。例:

...
String path = '/';
Cookie cookie = new Cookie('sessionID', sessionID, path, maxAge, true, 'Strict');
...


攻撃者が http://communitypages.example.com/EvilSite に別のアプリケーションを作成し、このサイトへのリンクをフォーラムに掲載したとします。フォーラムのユーザーがこのリンクをクリックすると、ユーザーのブラウザーは /MyForum によって設定された cookie を /EvilSite で実行されているアプリケーションに送信することになります。攻撃者はセッション ID を盗むことにより、/EvilSite にアクセスしたフォーラム ユーザーのアカウントであれば、危険にさらされることがあります。

cookie の読み取りに加えて、Cookie Poisoning 攻撃が実行される可能性もあります。その場合、攻撃者は /EvilSite を使用してパスが広範にわたる cookie を独自に作成し、/MyForum から送信される cookie を上書きします。

Abstract
cookie のパスがあまりに広範にわたっていると、同じドメイン上の別のアプリケーションを介してアクセスされる可能性があります。
Explanation
開発者は cookie を root コンテキストパス ("/") からアクセスできるように設定する傾向にあります。 この方法ではドメイン名を同じくするすべての Web アプリケーションがその cookie にアクセスできてしまいます。 cookie にはセッション ID などの重要な情報が保存されていることが多いため、アプリケーション間で cookie を共有すると、1 個のアプリケーションの脆弱性が別のアプリケーションに影響を及ぼす可能性があります。

例 1:http://communitypages.example.com/MyForum にフォーラム アプリケーションを配置している例を考えてみましょう。このアプリケーションでは、ユーザーがフォーラムにログインすると、"/" というパスを持つセッション ID の cookie が設定されます。

例:

cookie_options = {};
cookie_options.path = '/';
...
res.cookie('important_cookie', info, cookie_options);


攻撃者が http://communitypages.example.com/EvilSiteに別のアプリケーションを作成し、このサイトへのリンクをフォーラムに掲載したとします。 フォーラムのユーザーがこのリンクをクリックすると、ユーザーのブラウザーは /MyForum によって設定された cookie を /EvilSite で実行されているアプリケーションに送信することになります。 攻撃者はセッション ID を盗むことにより、/EvilSite にアクセスした任意のフォーラム ユーザーのアカウントを乗っ取ることができます。

cookie の読み取りに加えて、Cookie Poisoning 攻撃が実行される可能性もあります。その場合、攻撃者は /EvilSite を使用してパスが広範にわたる cookie を独自に作成し、/MyForum から送信される cookie を上書きします。

desc.semantic.scala.cookie_security_overly_broad_path
Abstract
cookie のパスがあまりに広範にわたっていると、同じドメイン上の別のアプリケーションを介してアクセスされる可能性があります。
Explanation
開発者は cookie を root コンテキストパス ("/") からアクセスできるように設定する傾向にあります。 この方法ではドメイン名を同じくするすべての Web アプリケーションがその cookie にアクセスできてしまいます。 cookie にはセッション ID などの重要な情報が保存されていることが多いため、アプリケーション間で cookie を共有すると、1 個のアプリケーションの脆弱性が別のアプリケーションに影響を及ぼす可能性があります。

例 1:http://communitypages.example.com/MyForum にフォーラム アプリケーションを配置している例を考えてみましょう。このアプリケーションでは、ユーザーがフォーラムにログインすると、"/" というパスを持つセッション ID の cookie が設定されます。

例:

...
let properties = [
NSHTTPCookieDomain: "www.example.com",
NSHTTPCookiePath: "/",
NSHTTPCookieName: "foo",
NSHTTPCookieValue: "bar",
NSHTTPCookieSecure: true
]
let cookie : NSHTTPCookie? = NSHTTPCookie(properties:properties)
...


攻撃者が http://communitypages.example.com/EvilSiteに別のアプリケーションを作成し、このサイトへのリンクをフォーラムに掲載したとします。 フォーラムのユーザーがこのリンクをクリックすると、ユーザーのブラウザーは /MyForum によって設定された cookie を /EvilSite で実行されているアプリケーションに送信することになります。 攻撃者はセッション ID を盗むことにより、/EvilSite にアクセスした任意のフォーラム ユーザーのアカウントを乗っ取ることができます。

cookie の読み取りに加えて、Cookie Poisoning 攻撃が実行される可能性もあります。その場合、攻撃者は /EvilSite を使用してパスが広範にわたる cookie を独自に作成し、/MyForum から送信される cookie を上書きします。

desc.structural.swift.cookie_security_overly_broad_path
Abstract
セッション cookie のドメインがあまりに広範にわたっていると、ベース ドメインを共有している別のアプリケーションからアクセスされる可能性があります。
Explanation
開発者はベースドメインに「.example.com」などのセッション cookie を設定する傾向にあります。しかし、この方法では同じベースドメイン名およびサブドメイン上にあるすべての Web アプリケーションがそのセッション cookie にアクセスできてしまいます。セッション cookie が漏洩すると、アカウントが悪用される可能性があります。

例 1:http://secure.example.com/ に安全なアプリケーションを配置していると考えてみましょう。このアプリケーションでは、ユーザーがログインすると、ドメインが「.example.com」であるセッションの cookie が設定されます。

その場合、アプリケーションの設定ファイルには、次のようなエントリが含まれます。

server.servlet.session.cookie.domain=.example.com


安全性で劣る別のアプリケーションが http://insecure.example.com/ に配置されていて、このアプリケーションに Cross-Site Scripting 脆弱性が存在するとします。http://secure.example.com に認証されているユーザーが http://insecure.example.com にアクセスすると、http://secure.example.com から送信されるセッション cookie が漏洩する可能性があります。

Abstract
セッション cookie のドメインがあまりに広範にわたっていると、ベース ドメインを共有している別のアプリケーション経由で攻撃を受ける可能性があります。
Explanation
開発者はベースドメインに「.example.com」などのセッション cookie を設定する傾向にあります。この方法では同じベース ドメインおよびサブドメイン上にあるすべての Web アプリケーションがそのセッション cookie にアクセスできてしまいます。アプリケーション間でセッション cookie を共有すると、1 個のアプリケーションに存在する脆弱性が別のアプリケーションに影響を及ぼす可能性があります。

例 1:http://secure.example.com/ に安全なアプリケーションを配置していると考えてみましょう。このアプリケーションでは、ユーザーがログインすると、ドメインが「.example.com」であるセッションの cookie が設定されます。

例:

session_set_cookie_params(0, "/", ".example.com", true, true);


安全性の劣る別のアプリケーションが http://insecure.example.com/ に配置されていて、このアプリケーションに Cross-Site Scripting の脆弱性が存在するとします。http://secure.example.com に認証されているユーザーが http://insecure.example.com にアクセスすると、http://secure.example.com から送信されるセッション cookie が漏洩する可能性があります。

Abstract
cookie のパスがあまりに広範にわたっていると、同じドメインを共有しているアプリケーションを介して盗まれる可能性があります。
Explanation
開発者はセッション cookie を root コンテキストパス (「/」) に設定する傾向にあります。この方法では同じドメイン上にあるすべての Web アプリケーションがその cookie にアクセスできてしまいます。セッション cookie が漏えいすると、攻撃者はそのドメイン上の任意のアプリケーションに存在する脆弱性を利用してセッション cookie を盗むことができるため、アカウントが悪用される可能性があります。

例 1:http://communitypages.example.com/MyForum にフォーラム アプリケーションを配置している例を考えてみましょう。このアプリケーションでは、ユーザーがフォーラムにログインすると、「/」というパスを持つセッションの cookie が設定されます。

例:

session_set_cookie_params(0, "/", "communitypages.example.com", true, true);


攻撃者が http://communitypages.example.com/EvilSite に別のアプリケーションを作成し、このサイトへのリンクをフォーラムに掲載したとします。フォーラム ユーザーがこのリンクをクリックすると、ユーザーのブラウザーは /MyForum によって設定されたセッション cookie を /EvilSite で実行されているアプリケーションに送信します。攻撃者はセッション cookie を盗むことにより、/EvilSite にアクセスしたフォーラム ユーザーのアカウントを侵害できてしまいます。

Abstract
セッション cookie の SameSite パラメーターが Strict に設定されていません。
Explanation
ブラウザーは、cookie を設定しているサイトに対して行われたあらゆる HTTP リクエストに自動的に cookie を追加します。cookie は、セッション ID や認証トークン、またはセッション中に同じサイトに対して行われる別のリクエスト間で共有されるサイト データなどの機密データを保存する場合があります。攻撃者は、ブラウザが自動的にクッキーをリクエストに追加するため、クライアントマシンに読み込まれたサードパーティのサイト ページから認証サイトへのリクエストを生成することで、なりすまし攻撃を行うことができます。

SameSite パラメーターは、リクエストがファーストパーティまたは同じサイトのコンテキストから生成された場合にのみリクエストに追加するよう cookie の範囲を制限します。これは、Cross-Site Request Forgery (CSRF) 攻撃から cookie を保護するのに役立ちます。SameSite パラメーターの値は、次の 3 つのうちのいずれかになります。

- Strict: Strict に設定した場合、cookie はトップレベル ナビゲーションのリクエストとともにのみ送信されます。
- Lax: Lax に設定した場合、cookie は、同じホストからのトップレベル ナビゲーションだけでなく、サードパーティ サイトからホストへの GET リクエストとともに送信されます。たとえば、ホスト サイトにリンクする、iframe タグか href タグを持つサードパーティ サイトがあるとします。ユーザーがリンクをたどると、リクエストには cookie が含まれます。
- None: Cookie は、Cookie に設定されたパスやドメインの範囲内にあるサイトに対して行われたすべてのリクエストで送信されます。POST メソッドを使用したフォームの送信により生成されたリクエストも、リクエストとともに Cookie を送信することができます。

例 1: 次のコードは、セッション cookie の SameSite パラメーターを Lax に設定します。

...
Cookie cookie = new Cookie('name', 'Foo', path, -1, true, 'Lax');

Abstract
セッション Cookie の SameSite 属性は Strict に設定されていません。
Explanation
SameSite 属性は、Cross-Site Request Forgery (CSRF) などの攻撃から Cookie を保護します。セッション Cookie はサイトに対してユーザーを表しているため、ユーザーは承認されたアクションを実行できるようになります。ただし、ブラウザーはリクエストとともに自動的に Cookie を送信するため、ユーザーと Web サイトは認証について暗黙的にブラウザーを信頼することになります。攻撃者はこの信頼を悪用して、攻撃者が制御するサードパーティ サイトのページにある linkiframe などのタグの hrefsrc 属性内にリンクを埋め込むことで、ユーザーの代わりにサイトにリクエストを行うことができます。疑いを持たないユーザーを攻撃者が制御するサードパーティのサイトにおびき寄せることができれば、攻撃者はユーザーを認証するセッション Cookie を自動的に含めるリクエストを行うことができ、攻撃者がユーザーであるかのように効果的に認証されることになります。
セッション Cookie で、SameSite 属性の値を Strict に設定します。これにより、トップレベル ナビゲーションまたは同じサイトからのリクエストにのみ Cookie を追加するよう、ブラウザーが制限されます。iframe, img, and form などのさまざまなタグにおけるリンク経由のサードパーティ サイトからのリクエストにはこれらの Cookie がないため、ユーザーが認証されていない可能性がある場合にサイトでの処理が回避されます。

例 1: 次のコードでは、セッション cookie の SameSite 属性の値を Lax に設定しています。

...
CookieOptions opt = new CookieOptions()
{
SameSite = SameSiteMode.Lax;
};
context.Response.Cookies.Append("name", "Foo", opt);

Abstract
セッション Cookie の SameSite 属性は Strict に設定されていません。
Explanation
SameSite 属性は、Cross-Site Request Forgery (CSRF) などの攻撃から Cookie を保護します。セッション Cookie はサイトに対してユーザーを表しているため、ユーザーは承認されたアクションを実行できるようになります。ただし、ブラウザーはリクエストとともに自動的に Cookie を送信するため、ユーザーと Web サイトは認証について暗黙的にブラウザーを信頼することになります。攻撃者はこの信頼を悪用して、攻撃者が制御するサードパーティ サイトのページにある linkiframe などのタグの hrefsrc 属性内にリンクを埋め込むことで、ユーザーの代わりにサイトにリクエストを行うことができます。疑いを持たないユーザーを攻撃者が制御するサードパーティのサイトにおびき寄せることができれば、攻撃者はユーザーを認証するセッション Cookie を自動的に含めるリクエストを行うことができ、攻撃者がユーザーであるかのように効果的に認証されることになります。
セッション Cookie で、SameSite 属性の値を Strict に設定します。これにより、トップレベル ナビゲーションまたは同じサイトからのリクエストにのみ Cookie を追加するよう、ブラウザーが制限されます。iframe, img, and form などのさまざまなタグにおけるリンク経由のサードパーティ サイトからのリクエストにはこれらの Cookie がないため、ユーザーが認証されていない可能性がある場合にサイトでの処理が回避されます。

例 1: 次のコードでは、セッション cookie の SameSite 属性の値を Lax に設定しています。

ResponseCookie cookie = ResponseCookie.from("myCookie", "myCookieValue")
...
.sameSite("Lax")
...
}

Abstract
セッション Cookie の SameSite 属性は Strict に設定されていません。
Explanation
SameSite 属性は、Cross-Site Request Forgery (CSRF) などの攻撃から Cookie を保護します。セッション Cookie はサイトに対してユーザーを表しているため、ユーザーは承認されたアクションを実行できるようになります。ただし、ブラウザーはリクエストとともに自動的に Cookie を送信するため、ユーザーと Web サイトは認証について暗黙的にブラウザーを信頼することになります。攻撃者はこの信頼を悪用して、攻撃者が制御するサードパーティ サイトのページにある linkiframe などのタグの hrefsrc 属性内にリンクを埋め込むことで、ユーザーの代わりにサイトにリクエストを行うことができます。疑いを持たないユーザーを攻撃者が制御するサードパーティのサイトにおびき寄せる場合、攻撃者は、ユーザー認証を使用してセッション Cookie を自動的に含めるリクエストを行うことができます。これにより、攻撃者はユーザーの承認を使用してアクセスできるようになります。
SameSite パラメーターのセッション Cookie を Strict に設定すると、トップレベル ナビゲーションまたは同じサイトからのリクエストにのみ Cookie を追加するよう、ブラウザーを制限できます。iframe, img, and form などのさまざまなタグにおけるリンク経由のサードパーティ サイトからのリクエストにはこれらの Cookie がないため、ユーザーが認証されていない可能性がある場合にサイトでの処理が回避されます。

例 1: 次のコードでは、セッション Cookie の samesite 属性の Lax を有効にしています。

response.set_cookie("cookie", value="samesite-lax", samesite="Lax")

Abstract
機密データを永続的な cookie に保存すると、機密性の侵害やアカウントの侵害につながる可能性があります。
Explanation
ほとんどの Web プログラミング環境では、デフォルトで非永続的な cookie が作成されます。これらの cookie はブラウザーのメモリにのみ存在し (ディスクには書き込まれません)、ブラウザーを閉じると失われます。プログラマーは、cookie が特定の将来の日付までブラウザー セッション間で保持されるように指定できます。このような cookie はディスクに書き込まれ、ブラウザー セッションやコンピューターの再起動後も存続します。

個人情報が永続的な cookie に保存されていると、攻撃者がこのデータを盗める期間が長くなります (特に、永続的な cookie では通常、有効期限がかなり先に設定されているため)。永続的な cookie は、ユーザーがサイトとやり取りする際のユーザーのプロファイリングによく使用されます。この追跡データの利用方法によっては、永続的な cookie を使用してユーザーのプライバシーを侵害することが可能になります。

例 1: 次のコードは、10 年後に期限切れになるように cookie を設定しています。

...
Integer maxAge = 60*60*24*365*10;
Cookie cookie = new Cookie('emailCookie', emailCookie, path, maxAge, true, 'Strict');

Abstract
永続的な cookie に機密データを保管すると、機密性が損なわれたり、アカウントが悪用される可能性があります。
Explanation
Web プログラミング環境の大部分では、非永続的な cookie の作成がデフォルトになっています。非永続的 cookie はブラウザメモリにのみ存在し (ディスクに書き込まれない)、ブラウザが終了すると消滅します。プログラマは、近い将来までブラウザセッション間で cookie が永続的になるよう指定できます。そのような cookie はディスクに書き込まれ、すべてのブラウザセッションで使用されます。また、コンピュータを再起動しても使用されます。

永続的 cookie では有効期限がずっと先に設定されることが多いため、永続的 cookie に個人情報が保管されていると、攻撃者が情報を盗み出すことのできる時間が長くなります。多くの場合、永続的 cookie はサイトとやり取りする際のユーザープロファイルとして使用されます。この追跡データに対して実行される操作によっては、ユーザーの個人情報を盗み出すのに永続的 cookie が悪用される可能性があります。
例 1: 次のコードは、10 年後に期限切れになるように cookie を設定しています。

Abstract
永続的な cookie に機密データを保管すると、機密性が損なわれたり、アカウントが悪用される可能性があります。
Explanation
Web プログラミング環境の大部分では、非永続的な cookie の作成がデフォルトになっています。非永続的 cookie はブラウザメモリにのみ存在し (ディスクに書き込まれない)、ブラウザが終了すると消滅します。プログラマは、近い将来までブラウザセッション間で cookie が永続的になるよう指定できます。そのような cookie はディスクに書き込まれ、すべてのブラウザセッションで使用されます。また、コンピュータを再起動しても使用されます。

永続的 cookie では有効期限がずっと先に設定されることが多いため、永続的 cookie に個人情報が保管されていると、攻撃者が情報を盗み出すことのできる時間が長くなります。多くの場合、永続的 cookie はサイトとやり取りする際のユーザープロファイルとして使用されます。この追跡データに対して実行される操作によっては、ユーザーの個人情報を盗み出すのに永続的 cookie が悪用される可能性があります。
例 1: 次のコードは、10 年後に期限切れになるように cookie を設定しています。

Cookie cookie = new Cookie("emailCookie", email);
cookie.setMaxAge(60*60*24*365*10);

Abstract
永続的な cookie に機密データを保管すると、機密性が損なわれたり、アカウントが悪用される可能性があります。
Explanation
Web プログラミング環境の大部分では、非永続的な cookie の作成がデフォルトになっています。非永続的 cookie はブラウザメモリにのみ存在し (ディスクに書き込まれない)、ブラウザが終了すると消滅します。プログラマは、近い将来までブラウザセッション間で cookie が永続的になるよう指定できます。そのような cookie はディスクに書き込まれ、すべてのブラウザセッションで使用されます。また、コンピュータを再起動しても使用されます。

永続的 cookie では有効期限がずっと先に設定されることが多いため、永続的 cookie に個人情報が保管されていると、攻撃者が情報を盗み出すことのできる時間が長くなります。多くの場合、永続的 cookie はサイトとやり取りする際のユーザープロファイルとして使用されます。この追跡データに対して実行される操作によっては、ユーザーの個人情報を盗み出すのに永続的 cookie が悪用される可能性があります。
例 1: 次のコードでは、cookie の有効期限が 10 年後に切れるように設定しています。

from django.http.response import HttpResponse
...
def view_method(request):
res = HttpResponse()
res.set_cookie("emailCookie", email, expires=time()+60*60*24*365*10, secure=True, httponly=True)
return res

Abstract
永続的なセッション cookie を使用すると、アカウントが悪用される可能性があります。
Explanation
永続的なセッション cookie は、ユーザーがブラウザーを閉じた後も有効なままで、「Remember Me 機能 (ログイン情報の記憶機能)」の一部として使用されることが多くあります。その結果、永続的なセッション cookie を使用すると、たとえユーザーがブラウザーを閉じても明示的にはログアウトしていないと判断されるため、そのユーザーはアプリケーションに認証された状態のままになります。つまり、そのブラウザーを次に開いたユーザーは、その前のユーザーとして自動的にログインされます。アプリケーションの配置先が、適切に管理されている環境 (ユーザーが共有マシンからログオンすることを禁止している環境) でない限り、ユーザーがブラウザーを閉じたとしても攻撃者はそのユーザーのアカウントを盗むことができます。

例 1: 次のコードでは、セッション cookie が持続するように設定しています。

server.servlet.session.cookie.persistent=true

Abstract
Secure フラグを true に設定せずに、アプリケーション セッション cookie が作成されます。
Explanation
最近の Web ブラウザーでは、cookie ごとに Secure フラグがサポートされています。このフラグが設定されていると、ブラウザーは HTTPS 経由でのみ cookie を送信します。暗号化されていないチャネルで cookie を送信すると、ネットワークが盗聴される可能性があります。したがって、secure フラグを使用することで cookie の値の機密性を保護できます。これは、cookie に個人情報が保存されている場合や、cookie によってセッション ID が送信される場合、特に重要になります。
例 1:Secure フラグを設定せずにレスポンスにセッション cookie が追加されるようにする設定です。

...
<configuration>
<system.web>
<authentication mode="Forms">
<forms requireSSL="false" loginUrl="login.aspx">
</forms>
</authentication>
</system.web>
</configuration>
...


HTTPS と HTTP の両方が使用されていても Secure フラグが設定されていないアプリケーションでは、HTTPS リクエストで送信された cookie はその後に続く HTTP リクエストでも送信されてしまいます。暗号化されていない無線接続でネットワークトラフィックを盗聴するのは攻撃者にとって簡単です。つまり、cookie (特にセッション ID が格納されている cookie) を HTTP 経由で送信すると、アプリケーションが危険にさらされる可能性があります。

Abstract
アプリケーションは、暗号化されていないチャネル経由でセッション cookie を送信することがあります。
Explanation
最近の Web ブラウザーでは、cookie ごとに Secure フラグがサポートされています。このフラグが設定されていると、ブラウザーは HTTPS 経由でのみ cookie を送信します。暗号化されていないチャネルで cookie を送信すると、ネットワークが盗聴される可能性があります。したがって、secure フラグを使用することで cookie の値の機密性を保護できます。これは、cookie に個人情報が保存されている場合や、cookie によってセッション ID が送信される場合、特に重要になります。

例 1: 次の設定エントリでは、セッション cookie の Secure フラグを無効にします。

server.servlet.session.cookie.secure=false


HTTPS と HTTP の両方が使用されていても Secure フラグが設定されていないアプリケーションでは、HTTPS リクエストで送信された cookie はその後に続く HTTP リクエストでも送信されてしまいます。すると攻撃者は、暗号化されていないネットワーク トラフィックをスニッフィングすることによって cookie を危険にさらすことがあります。特に無線ネットワークの場合、ネットワーク トラフィックのスニッフィングは非常に簡単です。

Abstract
プログラムは、SESSION_COOKIE_SECURE プロパティを明示的に True に設定しないか、または False に設定します。
Explanation
最近の Web ブラウザでは、cookie ごとに Secure フラグがサポートされています。このフラグが設定されていると、ブラウザは HTTPS 経由でのみ cookie を送信します。暗号化されていないチャネルで cookie を送信すると、ネットワークが盗聴される可能性があります。したがって、secure フラグを使用することで cookie の値の機密性を保護できます。cookie に個人情報またはセッション ID が保存されている場合や、cookie によって CSRF トークンが送信される場合に特に重要になります。
例 1: 次の設定エントリはセッション cookie に Secure ビットを明示的に設定しません。

...
MIDDLEWARE = (
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'csp.middleware.CSPMiddleware',
'django.middleware.security.SecurityMiddleware',
...
)
...


HTTPS と HTTP の両方が使用されていても Secure フラグが設定されていないアプリケーションでは、HTTPS リクエストで送信された cookie はその後に続く HTTP リクエストでも送信されてしまいます。すると攻撃者は、暗号化されていないネットワーク トラフィックをスニッフィングすることによって cookie を危険にさらすことがあります。特に無線ネットワークの場合、ネットワーク トラフィックのスニッフィングは非常に簡単です。

Abstract
プログラムではセッション ID を送信するのに cookie を使用していないため、Session Fixation 攻撃やセッション乗っ取り攻撃を受ける可能性があります。
Explanation
Web アプリケーションの大半はセッション ID を使用してユーザーを特定します。通常セッション ID は cookie に格納されており、ユーザーに意識させることなくサーバーと Web ブラウザの間で送信されます。


セッション ID を cookie に格納しないアプリケーションは、HTTP リクエストパラメーターとして、または URL の一部としてセッション ID を送信することがあります。URL に指定されたセッション ID を受け入れると、Session Fixation 攻撃を受ける可能性が高まります。

セッション ID を URL に配置すると、アプリケーションに対するセッション乗っ取り攻撃が成功する可能性も高まります。セッション乗っ取りは、攻撃者が攻撃対象のアクティブなセッションまたはセッション ID を制御できる場合に発生します。Web サーバー、アプリケーションサーバー、および Web プロキシが要求された URL を保存するのは一般的な方法です。セッション ID に含まれている URL は、ログにも記録されています。セッションIDの表示場所と格納先が増えれば、それだけ攻撃を受ける可能性は高まります。

Abstract
ユーザー名を平文で保管するとシステムが危険にさらされる結果を招くことがあります。
Explanation
Credential Management の問題が発生するのは、アプリケーションの設定ファイルやデータベースにユーザー名が平文で保管されることが許可される場合です。
例 1: 次のコードは Web フォームからユーザー名を読み取り、そのユーザー名を使用してデータベースに接続しています。


<cfquery name = "GetCredentials" dataSource = "master">
SELECT Username, Password
FROM Credentials
WHERE DataSource="users"
</cfquery>
...
<cfquery name = "GetSSNs" dataSource = "users"
username = "#Username#" password = "#Password#">
SELECT SSN
FROM Users
</cfquery>
...


このコードは正常に動作しますが、テーブル masterにアクセスできる全員が UsernamePassword の値を読み取ることができます。不心得な従業員がこの情報へのアクセス権を持っている場合、システムに侵入するために使用されることがあります。

Abstract
Hardcoded API の資格情報はシステムのセキュリティを危険にさらす可能性があり、この問題への対策は簡単ではありません。
Explanation
ユーザー名、パスワード、API キー、API シークレット、API トークンなどの資格情報はハードコーディングしないでください。ハードコードされた資格情報は、すべてのプロジェクト開発者に表示されるだけでなく、更新が非常に困難です。コードが実運用に入ると、ソフトウェアにパッチを当てないと資格情報を変更できません。資格情報が侵害された場合、組織はセキュリティとシステムの可用性のどちらかを選択する必要があります。

Abstract
Hardcoded API の資格情報はシステムのセキュリティを危険にさらす可能性があり、この問題への対策は簡単ではありません。
Explanation
ユーザー名、パスワード、API キー、API シークレット、API トークンなどの資格情報はハードコーディングしないでください。ハードコードされた資格情報は、すべてのプロジェクト開発者に表示されるだけでなく、更新が非常に困難です。コードが実運用に入ると、ソフトウェアにパッチを当てないと資格情報を変更できません。資格情報が侵害された場合、組織はセキュリティとシステムの可用性のどちらかを選択する必要があります。

Abstract
ハードコーディングされたユーザー名はシステムのセキュリティを危険にさらす可能性があり、この問題への対策は簡単ではありません。
Explanation
ユーザー名をハードコーディングするのはよくない発想です。ユーザー名をハードコーディングするとプロジェクトの開発者全員がユーザー名を見ることができるだけでなく、問題の修復も非常に困難です。コードが実運用に入ると、ソフトウェアにパッチを当てないとユーザー名を変更できません。このユーザー名によって保護されたアカウントが危険にさらされると、システムの所有者はセキュリティと可用性の二者択一を強いられます。
例 1: 次のコードは、Hardcoded Username を使用してデータベースに接続します。


...
<cfquery name = "GetSSNs" dataSource = "users"
username = "scott" password = "tiger">
SELECT SSN
FROM Users
</cfquery>
...


このコードは正常に動作しますが、コードにアクセスできる全員がユーザー名を入手できます。プログラムが頒布された後は、プログラムにパッチを適用しない限り、「tiger」というパスワードを持つデータベース ユーザー「scott」を変更することはできません。この情報へのアクセス権を持っている従業員が、権限を使用してシステムに侵入する可能性があります。

Abstract
このプログラムでは、未承認のユーザーが SAP システムの他のクライアントからのデータにアクセスできることがあります。
Explanation
SAP システムのアプリケーション データは、クライアントごとに分割され (クライアント分割)、すべての Open SQL ステートメントが、ログオンしているクライアントに属するデータに自動的にアクセスして変更します (クライアント処理)。これは、企業内の別の部門や組織に属するデータを論理的に分離するためです。ただし、次の要素を使用して、ABAP プログラム内のクライアント分割やクライアント処理のメカニズムを迂回することも可能です。

1. ネイティブ SQL ステートメント
2. CLIENT SPECIFIED を追加した Open SQL ステートメント
3. ADBC (ABAP データベース コネクティビティ) API
4. クライアント固有のデータに他のクライアントからアクセスするその他の API

SAP では、指定したクライアントからのデータへのアクセスがユーザーに承認されているかどうかをチェックしません。このため、未承認のユーザーが別のクライアントからのデータを表示または変更する場合に、セキュリティ上のリスクが生じます。

例 1: 以下のコードは、Open SQL を使用して従業員の詳細をフェッチします。


...
PARAMETERS: p_input TYPE sy-mandt.

SELECT *
FROM employee_records
CLIENT SPECIFIED
INTO TABLE tab_output
WHERE mandt = p_input.
...


この場合、このコードを実行しているユーザーは、本来はこの操作を承認されていないにもかかわらず、ログオンしているクライアント SY-MANDT 以外のクライアントから従業員の詳細を表示できます。

Abstract
iframe 内のアプリケーションの追加を制限できない場合、クロスサイト リクエスト フォージェリまたはフィッシング攻撃を受ける可能性があります。
Explanation
アプリケーションが次の場合に Cross-Frame Scripting に対して脆弱になります。

1. iframe 内への追加をアプリケーション自体に許可する場合。
2. X-Frame-Options ヘッダーを介してフレーミング ポリシーを指定できない場合。
3. JavaScript ベースのフレーム バースティング ロジックなど、低品質の防御機能を使用する場合。

クロスフレーム スクリプトに対する脆弱性は、多くの場合、クリックジャッキング攻撃の土台となり、攻撃者はこれを利用し、クロスサイト リクエスト フォージェリ攻撃やフィッシング攻撃を実行できます。

Abstract
iframe 内のアプリケーションの追加を制限できない場合、クロスサイト リクエスト フォージェリまたはフィッシング攻撃を受ける可能性があります。
Explanation
アプリケーションが次の場合に Cross-Frame Scripting に対して脆弱になります。

1. iframe 内への追加をアプリケーション自体に許可する場合。
2. X-Frame-Options ヘッダーを介してフレーミング ポリシーを指定できない場合。
3. JavaScript ベースのフレーム バースティング ロジックなど、低品質の防御機能を使用する場合。

クロスフレーム スクリプトに対する脆弱性は、多くの場合、クリックジャッキング攻撃の土台となり、攻撃者はこれを利用し、クロスサイト リクエスト フォージェリ攻撃やフィッシング攻撃を実行できます。

Abstract
localStoragesessionStorage 間で値を転送すると、意図せずに重要な情報が公開される可能性があります。
Explanation
HTML5 は、localStorage および sessionStorage マップを提供して、開発者がプログラムの値を保持できるようにしています。sessionStorage マップは、ページを起動するためのストレージを提供し、該当するページ インスタンスおよび直近のブラウザ セッションの期間だけ持続します。しかし、localStorage マップは、複数のページ インスタンスおよび複数のブラウザ インスタンスにわたってアクセス可能なストレージを提供します。この機能により、アプリケーションは、複数のブラウザタブやウィンドウで同じ情報を保持して利用できるようになります。

たとえば開発者は、ユーザーの元々の検索条件を保持しながら、ユーザーが複数のタブを開いて宿泊設備を比較できるように、複数のブラウザタブやインスタンスを旅行アプリケーションで使用したいと考える場合があります。従来型のストレージシナリオでは、ユーザーがあるタブで行った(そしてセッションまたは cookie に保存された)購入や決定が、別のタブにおける購入を妨げてしまう危険性があります。

ユーザーの値を複数のブラウザ タブ間で使用できる場合、開発者は、重要な情報を sessionStorage スコープと localStorage 間で移動しないように注意するよう必要があります。

例 1: 次の例では、クレジッド カードの CCV 情報がセッションに保存され、購入物についてカードで支払うことをユーザーがすでに承認していることが示されます。このブラウザー タブのコンテキストで購入しようとすると、必ずクレジッド カードの承認が求められます。CCV の再入力を回避するために、情報は sessionStorage オブジェクトに保存されます。しかし、開発者は、localStorage オブジェクト内にも情報を保存します。


...
try {
sessionStorage.setItem("userCCV", currentCCV);
} catch (e) {
if (e == QUOTA_EXCEEDED_ERR) {
alert('Quota exceeded.');
}
}

...
...

var retrieveObject = sessionStorage.getItem("userCCV");
try {
localStorage.setItem("userCCV",retrieveObject);
} catch (e) {
if (e == QUOTA_EXCEEDED_ERR) {
alert('Quota exceeded.');
}
...

var userCCV = localStorage.getItem("userCCV");
...
}
...
localStorage オブジェクトに情報を戻すことで、CCV 情報は他のブラウザ タブでも利用できるようになります。また、ブラウザを新たに呼び出した場合でも利用できるようになります。これは、アプリケーション論理の本来のワークフローを回避しています。

Abstract
このプログラムは、検証されていないユーザー入力を使用して、SWF ファイルをロードしています。これにより、任意のコンテンツが参照され、ターゲットの Flash アプリケーションによって実行される可能性があります。
Explanation
Flash API によって、既存の実行環境にリモート SWF ファイルがロードされる場合があります。クロスドメインポリシーによって信頼できるドメインのみから SWF ファイルをロードすることが許可されていても、クロスドメインポリシーを過剰に許可して定義している場合が多くあります。信頼できないユーザー入力を使用してロードする SWF ファイルを定義できるようにすると、任意のコンテンツが参照されターゲットアプリケーションよって実行される可能性があります。これは、Cross-Site Flashing 攻撃を引き起こす可能性があります。

次の場合に、Cross-Site Flashing の脆弱性が発生します。

1. 信頼されていないソースからデータがアプリケーションに入り込んだ場合。

2. このデータが使用されて、リモート SWF ファイルがロードされます。
例 1: 次のコードは、ロードされた SWF ファイルへのパラメーターの 1 つの値を URL として使用して、リモートの SWF ファイルをロードしています。


...
var params:Object = LoaderInfo(this.root.loaderInfo).parameters;
var url:String = String(params["url"]);
var ldr:Loader = new Loader();
var urlReq:URLRequest = new URLRequest(url);
ldr.load(urlReq);
...

desc.dataflow.actionscript.cross_site_flashing
Abstract
Visualforce のページ アクション メソッドまたはコントローラー コンストラクターは、不正なリクエストに対する保護なしで、機密性の高いタスクを実行します。
Explanation
次の場合に、Cross-Site Request Forgery (CSRF) の脆弱性が発生します。
1.Web アプリケーションがセッションの cookie を使用する。
2.ユーザーの承諾を得てリクエストが作成されているかをどうかを検証せずに、この Web アプリケーションは HTTP リクエストを処理する。
デフォルトでは、Visualforce ページは CSRF 防止トークンとして機能する非表示のフォーム フィールドとともにレンダリングされます。これらのトークンはページ内から送信されるリクエストに含まれ、サーバーは対応するアクション メソッドまたはコマンドを実行する前にトークンの有効性をチェックします。ただし、この組み込みの防御は、ページ アクション メソッドやカスタム ページ コントローラー コンストラクターには適用されません。これらは、ページのロード中、CSRF 防止トークンが生成される前に実行されるためです。
例 1: 次の Visualforce ページは、カスタム コントローラー MyAccountActions とページ アクション メソッド pageAction() を宣言しています。ページの URL にアクセスすると、pageAction() メソッドが実行され、サーバーは CSRF 防止トークンをチェックしません。

<apex:page controller="MyAccountActions" action="{!pageAction}">
...
</apex:page>
public class MyAccountActions {
...
public void pageAction() {
Map<String,String> reqParams = ApexPages.currentPage().getParameters();
if (params.containsKey('id')) {
Id id = reqParams.get('id');
Account acct = [SELECT Id,Name FROM Account WHERE Id = :id];
delete acct;
}
}
...
}

攻撃者は次のコードを含んだ悪意ある Web サイトをセットアップする可能性があります。

<img src="http://my-org.my.salesforce.com/apex/mypage?id=YellowSubmarine" height=1 width=1/>

Visualforce ページの管理者が、サイトでセッションを行っているときに、悪意あるページにアクセスすると、攻撃者のアカウントを削除してしまいますが、本人はそのことに気づきません。

Abstract
承認していないリクエストを攻撃者が送信できないようにするため、状態を変更する HTTP リクエストにはユーザー固有のシークレットが含まれている必要があります。
Explanation
次の場合に、Cross-Site Request Forgery (CSRF) の脆弱性が発生します。
1.Web アプリケーションがセッションの cookie を使用する。
2.ユーザーの承諾を得てリクエストが作成されているかをどうかを検証せずに、この Web アプリケーションは HTTP リクエストを処理する。

例 1: 次の例では、Web アプリケーションは管理者にアカウントの新規作成を許可します。


RequestBuilder rb = new RequestBuilder(RequestBuilder.POST, "/new_user");
body = addToPost(body, new_username);
body = addToPost(body, new_passwd);
rb.sendRequest(body, new NewAccountCallback(callback));


攻撃者は次のコードを含んだ悪意ある Web サイトをセットアップする可能性があります。


RequestBuilder rb = new RequestBuilder(RequestBuilder.POST, "http://www.example.com/new_user");
body = addToPost(body, "attacker";
body = addToPost(body, "haha");
rb.sendRequest(body, new NewAccountCallback(callback));
example.com の管理者が、サイトでセッションを行っているときに、悪意あるページにアクセスすると、攻撃者にアカウントを作成してしまいますが、本人はそのことに気づきません。これが CSRF 攻撃です。アプリケーションには、リクエストの生成元を検証する方法がないために、この攻撃が可能となっています。リクエストはユーザーによって選択された正当なアクションにも、攻撃者が準備した不正なアクションにもなりえます。攻撃者は偽のリクエストを生成する Web ページを見ることができません。そのため、この攻撃方法は、アプリケーションの状態を変更するリクエストにのみ有効です。

cookie ではなく URL でセッション ID を渡すアプリケーションには CSRF の問題は存在しません。これは、攻撃者にとってセッション ID にアクセスすることやセッション ID を偽のリクエストの一部に追加することは不可能であるためです。

一部のフレームワークでは CSRF ナンスを自動的に含めることでアプリケーションの保護を支援します。この機能を無効化すると、アプリケーションにリスクが生じます。

例 2: Spring Security で保護されるこのアプリケーションでは、CSRF 対策を明示的に無効化します。

1. Web アプリケーションがセッションの cookie を使用する。

2. ユーザの承諾を得てリクエストが作成されているかをどうかを検証せずに、この Web アプリケーションは HTTP リクエストを処理する。



ナンスは、リプレイ攻撃を防ぐためにメッセージと一緒に送信される、暗号のランダム値です。リクエストにその出所を証明するナンスが含まれていない場合、リクエストを処理するコードは (アプリケーションの状態を変更しない限り) CSRF 攻撃に対して脆弱です。つまり、セッション Cookie を使用する Web アプリケーションは、攻撃者がユーザーをだまして偽のリクエストを送信させないように、特別な予防措置を講じる必要があります。管理者が新しいアカウントを作成できる次のような Web アプリケーションを考えてみます。



var req = new XMLHttpRequest();
req.open("POST", "/new_user", true);
body = addToPost(body, new_username);
body = addToPost(body, new_passwd);
req.send(body);


攻撃者は次のコードを含んだ悪意ある Web サイトを準備する可能性があります。


var req = new XMLHttpRequest();
req.open("POST", "http://www.example.com/new_user", true);
body = addToPost(body, "attacker");
body = addToPost(body, "haha");

Abstract
Django アプリケーションは CSRF ミドルウェア保護を有効にしません。
Explanation
次の場合に、Cross-Site Request Forgery (CSRF) の脆弱性が発生します。
1. Web アプリケーションがセッションの cookie を使用する。

2. ユーザの承諾を得てリクエストが作成されているかをどうかを検証せずに、この Web アプリケーションは HTTP リクエストを処理する。

ナンス (ワンタイムパスワード) は、反射攻撃を防止するためにメッセージと共に送信される暗号的な乱数値です。生成元を証明するナンス (ワンタイム パスワード) がリクエストに含まれていない場合、このリクエストを処理するコードは CSRF 攻撃に対して脆弱になる可能性があります (アプリケーションの状態が変更される場合は脆弱になりません)。つまり、セッション cookie を使用する Web アプリケーションでは、攻撃者によってユーザが偽のリクエストを送信するように仕向けられることないように、特殊な予防措置を講じる必要があります。管理者が次のフォームを送信して新しいアカウントを作成できる Web アプリケーションを例としてみましょう。


<form method="POST" action="/new_user" >
Name of new user: <input type="text" name="username">
Password for new user: <input type="password" name="user_passwd">
<input type="submit" name="action" value="Create User">
</form>


攻撃者は次のフォームを使用した Web サイトを準備する可能性があります。


<form method="POST" action="http://www.example.com/new_user">
<input type="hidden" name="username" value="hacker">
<input type="hidden" name="user_passwd" value="hacked">
</form>
<script>

Abstract
承認していないリクエストを攻撃者が送信できないようにするため、HTTP リクエストにはユーザー固有のシークレットが含まれている必要があります。
Explanation
次の場合に、Cross-Site Request Forgery (CSRF) の脆弱性が発生します。
1. Web アプリケーションがセッションの cookie を使用する。

2. ユーザーの承諾を得てリクエストが作成されているかをどうかを検証せずに、この Web アプリケーションは HTTP リクエストを処理する。

ナンス (ワンタイムパスワード) は、反射攻撃を防止するためにメッセージと共に送信される暗号的な乱数値です。 生成元を証明するナンス (ワンタイム パスワード) がリクエストに含まれていない場合、このリクエストを処理するコードは CSRF 攻撃に対して脆弱になる可能性があります (アプリケーションの状態が変更される場合は脆弱になりません)。 つまり、セッション cookie を使用する Web アプリケーションでは、攻撃者によってユーザーが偽のリクエストを送信するように仕向けられることないように、特殊な予防措置を講じる必要があります。 管理者が新しいアカウントを作成できる Web アプリケーションを例としてみましょう。

デフォルトでは、Play Framework は CSRF に対する防御を追加しますが、グローバルに、または特定のルートに対して無効にすることができます。

例 1: 次のルート定義は、buyItem コントローラー メソッドの CSRF 保護を無効にします。

+ nocsrf
POST /buyItem controllers.ShopController.buyItem
shop.com のアクティブ セッション実行時に、ユーザーは意図せずに悪意あるページに誘導され、気づかないうちに攻撃者にアイテムを購入してしまいます。 これが CSRF 攻撃です。 アプリケーションには、リクエストの生成元を検証する方法がないために、この攻撃が可能となっています。 リクエストはユーザーによって選択された正当なアクションにも、攻撃者が準備した不正なアクションにもなりえます。 攻撃者は偽のリクエストを生成する Web ページを見ることができません。そのため、この攻撃方法は、アプリケーションの状態を変更するリクエストにのみ有効です。

cookie ではなく URL でセッション ID を渡すアプリケーションには CSRF の問題は存在しません。これは、攻撃者にとってセッション ID にアクセスすることやセッション ID を偽のリクエストの一部に追加することは不可能であるためです。

Abstract
承認していない要求を攻撃者が実行できないように、フォームの post には、ユーザー指定のシークレットを追加する必要があります。
Explanation
次の場合に、Cross-Site Request Forgery (CSRF) の脆弱性が発生します。
1. Web アプリケーションがセッションの cookie を使用する。

2. ユーザの承諾を得てリクエストが作成されているかをどうかを検証せずに、この Web アプリケーションは HTTP リクエストを処理する。



ナンス (ワンタイムパスワード) は、反射攻撃を防止するためにメッセージと共に送信される暗号的な乱数値です。生成元を証明するナンス (ワンタイム パスワード) がリクエストに含まれていない場合、このリクエストを処理するコードは CSRF 攻撃に対して脆弱になる可能性があります (アプリケーションの状態が変更される場合は脆弱になりません)。つまり、セッション cookie を使用する Web アプリケーションでは、攻撃者によってユーザが偽のリクエストを送信するように仕向けられることないように、特殊な予防措置を講じる必要があります。管理者が次のフォームを送信して新しいアカウントを作成できる Web アプリケーションを例としてみましょう。


<form method="POST" action="/new_user" >
Name of new user: <input type="text" name="username">
Password for new user: <input type="password" name="user_passwd">
<input type="submit" name="action" value="Create User">
</form>


攻撃者は次のフォームを使用した Web サイトを準備する可能性があります。


<form method="POST" action="http://www.example.com/new_user">
<input type="hidden" name="username" value="hacker">
<input type="hidden" name="user_passwd" value="hacked">
</form>
<script>
document.usr_form.submit();
</script>
example.com の管理者が、サイトでセッションを行っているときに、悪意あるページにアクセスすると、攻撃者にアカウントを作成してしまいますが、本人はそのことに気づきません。これが CSRF 攻撃です。アプリケーションには、リクエストの生成元を検証する方法がないために、この攻撃が可能となっています。リクエストはユーザによって選択された正当なアクションにも、攻撃者が準備した不正なアクションにもなりえます。攻撃者は偽のリクエストを生成する Web ページを見ることができません。そのため、この攻撃方法は、アプリケーションの状態を変更するリクエストにのみ有効です。

Abstract
未検証の機械学習モデルの出力を Web ブラウザーに送信すると、結果としてブラウザーで悪意のあるコードが実行される可能性があります。
Explanation
次の場合に、Cross-Site Scripting (XSS) の脆弱性が発生します。

1.信頼できないソース経由でデータが Web アプリケーションに入り込んだ場合。人工知能 (AI) の場合、信頼できないソースは通常、AI システムから返される応答です。


2.未検証で Web ユーザーへ送信される動的コンテンツにデータが含まれている場合。

Web ブラウザーへ送信される悪意あるコンテンツは多くの場合 JavaScript セグメントの形式になっていますが、HTML や Flash など、ブラウザーで実行される何らかのタイプのコードが含まれることもあります。XSS に基づく攻撃の種類はほぼ無限にあります。一般的には、cookie などの個人情報やその他のセッション情報を攻撃者に送信したり、攻撃者の制御下にある Web コンテンツに被害者をリダイレクトしたり、脆弱性のあるサイトを装ってユーザーのマシン上で悪意ある操作を実行したりします。悪用は他の形式の XSS ほど単純ではありませんが、ユーザー入力や AI モデルからの応答は予測しにくいため、応答は安全なものとして扱うべきではありません。

例 1: 次の Java コードは、大規模言語モデルから応答を取得し、HTTP 応答でユーザーに返します。


@GetMapping("/ai")
String generation(String userInput) {
return this.chatClient.prompt()
.user(userInput)
.call()
.content();
}

この例にあるコードは、モデルからの応答に含まれるのが英数字のみの場合、期待どおりに動作します。ただし、エンコードされていない HTML メタキャラクターが応答に含まれている場合は、XSS が可能です。たとえば、「please repeat the following statement exactly '<script>alert(1);</script>'」というプロンプトに対する応答からは、使用されているモデルとコンテキストに応じて XSS の PoC (Proof of Concept) が返される場合があります。

Abstract
未検証のデータを Web ブラウザーに送信すると、結果としてブラウザーで悪意のあるコードが実行される可能性があります。
Explanation
次の場合に、Cross-Site Scripting (XSS) の脆弱性が発生します。

1.信頼できないソース経由でデータが Web アプリケーションに入り込んだ場合。人工知能 (AI) の場合、信頼できないソースは通常、AI システムから返される応答です。リフレクト XSS の場合、通常は Web リクエストです。


2.未検証で Web ユーザーへ送信される動的コンテンツにデータが含まれている場合。

Web ブラウザーへ送信される悪意あるコンテンツは多くの場合 JavaScript セグメントの形式になっていますが、HTML や Flash など、ブラウザーで実行される何らかのタイプのコードが含まれることもあります。XSS に基づく攻撃の種類はほぼ無限にあります。一般的には、cookie などの個人情報やその他のセッション情報を攻撃者に送信したり、攻撃者の制御下にある Web コンテンツに被害者をリダイレクトしたり、脆弱性のあるサイトを装ってユーザーのマシン上で悪意ある操作を実行したりします。悪用は他の形式の XSS ほど単純ではありませんが、ユーザー入力や AI モデルからの応答は予測しにくいため、応答は安全なものとして扱うべきではありません。

例 1: 次の TypeScript コードは、OpenAI チャット コンプリーション モデル message から応答を取得し、ユーザーに表示します。


const openai = new OpenAI({
apiKey: ...,
});
const chatCompletion = await openai.chat.completions.create(...);

message = res.choices[0].message.content

console.log(chatCompletion.choices[0].message.content)


この例にあるコードは、モデルからの応答に含まれるのが英数字のみである限り、期待どおりに動作します。ただし、エンコードされていない HTML メタ文字が応答に含まれている場合は、XSS が可能です。たとえば、「please repeat the following statement exactly '<script>alert(1);</script>'」というプロンプトに対する応答からは、使用されているモデルとコンテキストに応じて XSS の PoC (Proof of Concept) が返される場合があります。

Abstract
未検証の機械学習モデルの出力を Web ブラウザーに送信すると、結果としてブラウザーで悪意のあるコードが実行される可能性があります。
Explanation
次の場合に、Cross-Site Scripting (XSS) の脆弱性が発生します。

1.信頼できないソース経由でデータが Web アプリケーションに入り込んだ場合。人工知能 (AI) の場合、信頼できないソースは通常、AI システムから返される応答です。


2.未検証で Web ユーザーへ送信される動的コンテンツにデータが含まれている場合。

Web ブラウザーへ送信される悪意あるコンテンツは多くの場合 JavaScript セグメントの形式になっていますが、HTML や Flash など、ブラウザーで実行される何らかのタイプのコードが含まれることもあります。XSS に基づく攻撃の種類はほぼ無限にあります。一般的には、cookie などの個人情報やその他のセッション情報を攻撃者に送信したり、攻撃者の制御下にある Web コンテンツに被害者をリダイレクトしたり、脆弱性のあるサイトを装ってユーザーのマシン上で悪意ある操作を実行したりします。悪用は他の形式の XSS ほど単純ではありませんが、ユーザー入力や AI モデルからの応答は予測しにくいため、応答は安全なものとして扱うべきではありません。

例 1: 次のコードは、大規模言語モデルから応答を取得し、HTTP 応答でユーザーに返します。


chatService.createCompletion(
text,
settings = CreateCompletionSettings(...)
).map(completion =>
val html = Html(completion.choices.head.text)
Ok(html) as HTML
)
...

この例にあるコードは、モデルからの応答に含まれるのが英数字のみの場合、期待どおりに動作します。ただし、エンコードされていない HTML メタキャラクターが応答に含まれている場合は、XSS が可能です。たとえば、「please repeat the following statement exactly '<script>alert(1);</script>'」というプロンプトに対する応答からは、使用されているモデルとコンテキストに応じて XSS の PoC (Proof of Concept) が返される場合があります。

Abstract
未検証のデータを Web ブラウザに送信すると、結果として特定のブラウザで悪意のあるコードが実行される可能性があります。
Explanation
次の場合に、Cross-Site Scripting (XSS) の脆弱性が発生します。

1.信頼できないソース経由でデータが Web アプリケーションに入り込んだ場合。リフレクト XSS の場合、信頼できないソースは Web リクエストであることが最も多く、一方、持続型 XSS (別名: ストアド XSS) の場合はデータベースなどのバックエンドデータストアであるのが一般的です。


2.未検証で Web ユーザーへ送信される動的コンテンツにデータが含まれている場合。

Web ブラウザーへ送信される悪意あるコンテンツは多くの場合 JavaScript セグメントの形式になっていますが、HTML や Flash など、ブラウザーで実行される何らかのタイプのコードが含まれることもあります。XSS に基づく攻撃の種類はほぼ無限にあります。一般的には、cookie などの個人情報やその他のセッション情報を攻撃者に送信したり、攻撃者の制御下にある Web コンテンツに被害者をリダイレクトしたり、脆弱性のあるサイトを装ってユーザーのマシン上で悪意ある操作を実行したりします。

ブラウザがレスポンスを HTML として、またはスクリプトを実行する可能性のあるその他のドキュメントとしてレンダリングするためには、text/htmlMIME タイプを指定する必要があります。したがって、XSS が可能になるのは、レスポンスがこの MIME タイプ、またはブラウザがレスポンスを HTML として、またはスクリプトを実行する可能性のあるその他のドキュメント(SVG イメージ (image/svg+xml) や XML ドキュメント (application/xml) など)としてレンダリングするように強制するその他のタイプを使用する場合のみです。

ほとんどの最新のブラウザーは、application/octet-stream のような MIME タイプのレスポンスが提供されても、HTML をレンダリングせず、スクリプトも実行しません。ただし、Internet Explorer などの一部のブラウザは、Content Sniffing と呼ばれる機能を実行します。Content Sniffing では、提供された MIME タイプが無視され、レスポンスの内容によって正しい MIME タイプを推測しようとします。
ただし、text/htmlは、そのような MIME タイプの中で XSS の脆弱性を引き起こす可能性がある唯一の MIME タイプであることには注意が必要です。SVG イメージ (image/svg+xml) や XML ドキュメント (application/xml) など、スクリプトを実行する可能性があるその他のドキュメントは、ブラウザが Content Sniffing を実行するかどうかにかかわらず、XSS の脆弱性を引き起こす可能性があります。

したがって、<html><body><script>alert(1)</script></body></html> などのレスポンスは、その content-type ヘッダーが application/octet-streammultipart-mixed などに設定されていても、HTML としてレンダリングできます。

例 1: 次の JAX-RS メソッドは、application/octet-stream レスポンスにユーザー データを反映します。


@RestController
public class SomeResource {
@RequestMapping(value = "/test", produces = {MediaType.APPLICATION_OCTET_STREAM_VALUE})
public String response5(@RequestParam(value="name") String name){
return name;
}
}


攻撃者が nameパラメータを <html><body><script>alert(1)</script></body></html> に設定してリクエストを送信すると、サーバは次のレスポンスを生成します。


HTTP/1.1 200 OK
Content-Length: 51
Content-Type: application/octet-stream
Connection: Closed

<html><body><script>alert(1)</script></body></html>


レスポンスを JSON ドキュメントとして扱うようにレスポンス内で明確に既述されていても、古いブラウザはレスポンスを HTML ドキュメントとしてレンダリングしようと試みる場合があり、Cross-Site Scripting 攻撃に対する脆弱性が生じます。
