Docker用Vulsを使用した動作確認

 

 

構成

   f:id:pocket01:20171203164658p:plain

実施したいこと

脆弱性診断出来るツールのdocker環境(version:1.12.6)用Vuls導入

 ・Web(テスト用)サーバのスキャン

 ・結果をレポートで出力

  ZAPと同様に脆弱性判断する指標材料として使用

公式のvulsインストール方法を元に導入手順を確認

 

参考先(vulsインストール)

https://github.com/future-architect/vuls/blob/master/README.ja.md

https://github.com/future-architect/vuls/tree/master/setup/docker

 

事前準備(SCAN対象ホスト)

SSHでKYEを使用したログイン可能とする

実行対象へのパッケージ追加

■yum-utilsの追加
# yum install -y yum-utils 

※yum-utils を追加しないと、configtestやSCAN実施時に

  ERROR [0001] yum-utils is not installed
  ERROR [localhost] Error: 0001, err: [yum-utils is not installed]

 みたいなエラーが出て止まりました。

実施

Vuls用ディレクトリ移動

# cd 

各dockerイメージを取得

■go-cve-dictionary
# docker pull vuls/go-cve-dictionary
# docker run --rm vuls/go-cve-dictionary -v

CVE-2017-11176 10.0 HIGH (nvd)
The mq_notify function in the Linux kernel through 4.11.9 does not set the sock
pointer to NULL upon entry into the retry logic. During a user-space close of a
Netlink socket, it allows attackers to cause a denial of service

The http.c:skip_short_body() function is called in some circumstances, such as
when processing redirects. When the response is sent chunked in wget before
1.19.2, the chunk parser uses strtol() to read each chunk's length, but doesn't
