Cwe 78

🧬 CWE Related 120
slug: cwe-78

Explanation

CWE-78は「ユーザー入力をシェルコマンドの一部として使うとき、適切にエスケープせず、攻撃者がコマンドを追加実行できてしまう欠陥」のことです。 例えば `ping {ユーザー入力IP}` の {ユーザー入力IP} に `; rm -rf /` のような文字列を入れられると、サーバー上のファイルが削除されます。 対策は「シェル経由を避け、引数を配列として直接渡す (PHPなら escapeshellarg)」。
📌 Example
Shellshock (CVE-2014-6271): Bashの脆弱性で、Webサーバーへの普通のリクエスト経由で任意のシェルコマンドが実行できた歴史的な事件。
