Vulnerability in libspring-java (DEBIAN-CVE-2018-1272)

Summary

Vulnerability in libspring-java (DEBIAN-CVE-2018-1272). Successful exploitation can lead to full system takeover. Mitigation: upgrade to 4.3.19-1 or later.

Original description

The description as published by the source.

Spring Framework, versions 5.0 prior to 5.0.5 and versions 4.3 prior to 4.3.15 and older unsupported versions, provide client-side support for multipart requests. When Spring MVC or Spring WebFlux server application (server A) receives input from a remote client, and then uses that input to make a multipart request to another server (server B), it can be exposed to an attack, where an extra multipart is inserted in the content of the request from server A, causing server B to use the wrong value for a part it expects. This could to lead privilege escalation, for example, if the part content represents a username or user roles.

Response actions

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

1
Identify exposure identify
```
grep -r 'libspring-java' . | 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 libspring-java 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 libspring-java to 4.3.19-1
```
ステージング環境で 4.3.19-1 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。
