❓ What is the problem
**unsafe deserialization** (CWE-502) exists in h2o. Attackers reach the vulnerable code path via `POST /99/ImportSQLTable` without authentication.
📍 Affected scope
h2o — . Attack surface: POST /99/ImportSQLTable / POST /3/SaveToHiveTable.
🔥 Severity
Severity: ?. Successful exploitation can lead to full system takeover
🔧 How to fix
Update to **3.46.0.6**.
🛡️ Workaround
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
🔍 Detection
Search webserver/proxy logs for unusual `POST /99/ImportSQLTable` requests with malformed payloads or SQL meta-characters. Run `grep -r 'h2o' .` against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.
Response Actions (7 steps)
Concrete steps and command examples for SOC/SRE teams to execute in order
-
1Identify exposure identify
grep -r 'h2o' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で `h2o` を grep し、稼働しているサービス・バージョンを把握する。
-
3Hunt for indicators of compromise detect
grep 'POST /99/ImportSQLTable' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで `POST /99/ImportSQLTable` への異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。
-
6Apply patch patch
Upgrade h2o to 3.46.0.6ステージング環境で 3.46.0.6 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスと、Step 3 で見つけた異常検知の続報チェックを含めること。
-
7Post-deployment verification verify
Replay attack against POST /99/ImportSQLTable on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 3 と同じログクエリでアラート再発が無いか継続監視。
