Cross-Site Scripting

⚔️ Attack Types Related 27
slug: xss

Explanation

XSSは「Webページの中に、攻撃者の悪意あるJavaScriptを忍び込ませる」攻撃です。 例えば掲示板に `<script>盗む()</script>` のような投稿をして、それを見た他のユーザーのCookie (ログイン情報) を盗む、といった攻撃が典型的です。 対策は「ユーザー入力を画面に出すときに、HTMLとして無害化 (エスケープ) する」こと。多くのフレームワークでは標準で対策されています。
📌 Example
2005年MySpaceワーム「Samy」: 1人の投稿が見るだけで他人のプロフィールにコピーされ、24時間で100万人に感染した有名事件。
