Server-Side Request Forgery

⚔️ Attack Types Related 17
slug: ssrf

Explanation

SSRFは「外部からのリクエストを、サーバーが内部ネットワークに転送してしまう」脆弱性です。 たとえば「画像URLを貼って」と言われてWebサービスがそのURLを取りに行く機能で、攻撃者が `http://169.254.169.254/` (AWSの内部メタデータURL) を入れると、AWSの認証情報が漏洩する、というのが典型例。 クラウド時代に特に危険視されている脆弱性です。
📌 Example
Capital One事件 (2019, 1億人の個人情報流出): WAFのSSRF脆弱性経由でAWS認証情報が窃取され、S3バケットから個人情報を全件取られた。
