Cwe 22

🧬 CWE Related 96
slug: cwe-22

Explanation

CWE-22は「ファイル名のパスをユーザー入力から組み立てるとき、`../` のような相対パス記号をきちんと無害化せず、本来アクセスできないファイルを読み書きされてしまう欠陥」のことです。 ファイルダウンロード機能・画像表示機能・テンプレート機能でよく見られます。 対策は「絶対パスへの正規化 + 許可されたディレクトリ内かのチェック」、または「ファイル名にIDのみを使い、パス記号を一切使わない設計」。
📌 Example
CVE-2024-57726 (SimpleHelp): zipファイル展開時のZip Slip攻撃で、サーバー上の任意の場所にファイル書き込みされる脆弱性。CISA KEV入り。
