Vulnerability in electrum (DEBIAN-CVE-2018-6353)

Summary

Vulnerability in electrum (DEBIAN-CVE-2018-6353). Successful exploitation can lead to full system takeover. Mitigation: upgrade to 3.2.3-1 or later.

Original description

The description as published by the source.

The Python console in Electrum through 2.9.4 and 3.x through 3.0.5 supports arbitrary Python code without considering (1) social-engineering attacks in which a user pastes code that they do not understand and (2) code pasted by a physically proximate attacker at an unattended workstation, which makes it easier for attackers to steal Bitcoin via hook code that runs at a later time when the wallet password has been entered, a different vulnerability than CVE-2018-1000022.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

1
Identify exposure identify
```
grep -r 'electrum' . | 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 electrum を grep し、稼働しているサービス・バージョンを把握する。
2
Apply patch patch
```
Upgrade electrum to 3.2.3-1
```
ステージング環境で 3.2.3-1 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を含めること。
3
Post-deployment verification verify
```
Confirm patched version is live in production
```
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。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
