Vulnerability in python-aiohttp (UBUNTU-CVE-2024-23829)

Summary

Vulnerability in python-aiohttp (UBUNTU-CVE-2024-23829). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 3.8.1-4ubuntu0.2+esm1 or later.

Original description

The description as published by the source.

aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. Security-sensitive parts of the Python HTTP parser retained minor differences in allowable character sets, that must trigger error handling to robustly match frame boundaries of proxies in order to protect against injection of additional requests. Additionally, validation could trigger exceptions that were not handled consistently with processing of other malformed input. Being more lenient than internet standards require could, depending on deployment environment, assist in request smuggling. The unhandled exception could cause excessive resource consumption on the application server and/or its logging facilities. This vulnerability exists due to an incomplete fix for CVE-2023-47627. Version 3.9.2 fixes this vulnerability.

Response actions

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

1
Identify exposure identify
```
grep -r 'python-aiohttp' . | 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 python-aiohttp 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 python-aiohttp to 3.8.1-4ubuntu0.2+esm1
```
ステージング環境で 3.8.1-4ubuntu0.2+esm1 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。
