概要

Trivy(tri发音像trigger,vy发音像envy)是一个简单而全面的容器漏洞扫描程序。Trivy可检测操作系统软件包(Alpine,RHEL,CentOS等)和应用程序依赖项(Bundler,Composer,npm,yarn等)的漏洞。此外,Trivy也非常易于使用。只需安装二进制文件即可执行扫描,你只需指定扫描容器的镜像名称即可。

它被认为适用于CI。在推送到容器注册表之前,你可以轻松扫描本地容器镜像。详情请参阅此处

特性

全面的漏洞检测

操作系统(Alpine,Red Hat Universal Base Image,Red Hat Enterprise Linux,CentOS,Debian和Ubuntu)

应用程序依赖(Bundler,Composer,Pipenv,Poetry,npm,yarn和Cargo)

使用简单

仅需指定镜像名称

请参阅快速入门和示例

安装简便

无需安装DB,库等先决条件。

apt-get install,yum install和brew install都可以。

高精确度

特别是针对Alpine Linux和RHEL/CentOS;

其他操作系统的精确度也很高。

DevSecOps

适用于CI,如Travis CI,CircleCI,Jenkins等。

安装

RHEL/CentOS

将存储库设置添加到/etc/yum.repos.d。

$ sudo vim /etc/yum.repos.d/trivy.repo
[trivy]
name=Trivy repository
baseurl=https://knqyf263.github.io/trivy-repo/rpm/releases/$releasever/$basearch/
gpgcheck=0
enabled=1
$ sudo yum -y update
$ sudo yum -y install trivy

$ rpm -ivh https://github.com/knqyf263/trivy/releases/download/v0.0.15/trivy_0.0.15_Linux-64bit.rpm

Debian/Ubuntu

将[CODE_NAME]替换为你的代码名称

CODE_NAME:wheezy,jessie,stretch,buster,trusty,xenial,bionic

$ sudo apt-get install apt-transport-https gnupg
$ wget -qO - https://knqyf263.github.io/trivy-repo/deb/public.key | sudo apt-key add -
$ echo deb https://knqyf263.github.io/trivy-repo/deb [CODE_NAME] main | sudo tee -a /etc/apt/sources.list.d/trivy.list
$ sudo apt-get update
$ sudo apt-get install trivy

$ sudo apt-get install rpm
$ wget https://github.com/knqyf263/trivy/releases/download/v0.0.15/trivy_0.0.15_Linux-64bit.deb
$ sudo dpkg -i trivy_0.0.15_Linux-64bit.deb

Mac OS X / Homebrew

你可以在Mac OS上使用homebrew。

$ brew install knqyf263/trivy/trivy

二进制(包括Windows)

此页面获取最新版本,并下载适用于你操作系统/架构的存档文件。解压缩该文件,并将二进制文件放在$PATH中(在UNIX-y系统上,位于/usr/local/bin)。确保执行位已打开。

你需要安装rpm命令来扫描RHEL/CentOS。

从源码

$ mkdir -p $GOPATH/src/github.com/knqyf263
$ cd $GOPATH/src/github.com/knqyf263
$ git clone https://github.com/knqyf263/trivy
$ cd trivy/cmd/trivy/
$ export GO111MODULE=on
$ go install

快速开始

只需指定镜像名称(和标签)即可。缓存中出现问题时应避免使用最新标签。请参阅清除镜像缓存部分。

基本使用

$ trivy [YOUR_IMAGE_NAME]

示例

$ trivy python:3.4-alpine

结果

Docker

将[YOUR_CACHE_DIR]替换为计算机上的缓存目录。

$ docker run --rm -v [YOUR_CACHE_DIR]:/root/.cache/ knqyf263/trivy [YOUR_IMAGE_NAME]

macOS示例:

$ docker run --rm -v $HOME/Library/Caches:/root/.cache/ knqyf263/trivy python:3.4-alpine

如果要扫描主机上的镜像,则需安装docker.sock。

$ docker run --rm -v /var/run/docker.sock:/var/run/docker.sock \
    -v $HOME/Library/Caches:/root/.cache/ knqyf263/trivy python:3.4-alpine

如果发生错误,请重新pull最新的knqyf263/trivy。

跳过漏洞数据库的更新

Trivy在开始运行时会更新漏洞数据库。这通常不会花费太多的时间,因为它是一个差异的更新。但是如果你想跳过这个过程,可以使用--skip-update选项。

$ trivy --skip-update python:3.4-alpine3.9

结果:

2019-05-16T12:48:08.703+0900    INFO    Detecting Alpine vulnerabilities...

仅更新你指定分发的漏洞数据库

默认情况下,Trivy会更新所有分发的漏洞数据库。你也可以使用--only-update选项,指定分发的漏洞数据库。

$ trivy --only-update alpine,debian python:3.4-alpine3.9
$ trivy --only-update alpine python:3.4-alpine3.9

忽略未修复的漏洞

默认情况下,Trivy还会检测未修补/不可修复的漏洞。这意味着即使你更新了所有的软件包,也无法修复这些漏洞。如果你想忽略它们,可以使用--ignore-unfixed选项。

$ trivy --ignore-unfixed ruby:2.3.0

结果:

指定退出代码

默认情况下,即使检测到漏洞,Trivy也会以代码0退出。如果要使用非0代码退出,可以使用--exit-code选项。

$ trivy --exit-code 1 python:3.4-alpine3.9

+---------+------------------+----------+-------------------+---------------+--------------------------------+

此选项对CI/CD很有用。在以下示例中,仅当发现严重漏洞时,测试才会失败。

$ trivy --exit-code 0 --severity MEDIUM,HIGH ruby:2.3.0
$ trivy --exit-code 1 --severity CRITICAL ruby:2.3.0

忽略指定漏洞

使用.trivyignore。

$ cat .trivyignore
# Accept the risk
CVE-2018-14618

# No impact in our settings
CVE-2019-1543

$ trivy python:3.4-alpine3.9

重启

使用--reset选项清除所有缓存和数据库。在此之后,需要很长时间才能在本地重建漏洞数据库。

$ trivy --reset

结果:

2019-05-16T13:05:31.935+0900    INFO    Resetting...

持续集成(CI)

扫描Travis CI/CircleCI内置的镜像。如果发现漏洞,测试将失败。如果你不想测试失败,请指定--exit-code 0。

注意:第一次可能需要等待一段时间(第二次缓存后会快许多)

私有Docker Registry的授权

Trivy可以从私有注册表下载镜像,而无需安装Docker和任何第三方的工具。那是因为它很容易在CI进程中运行。

你所要做的就是安装Trivy并设置ENV vars。但我并不建议在你的本地计算机上使用ENV vars。

Docker Hub

Docker Hub需要TRIVY_AUTH_URL,TRIVY_USERNAME和TRIVY_PASSWORD。从公共存储库下载时,你不需要设置ENV变量。

export TRIVY_AUTH_URL=https://registry.hub.docker.com
export TRIVY_USERNAME={DOCKERHUB_USERNAME}
export TRIVY_PASSWORD={DOCKERHUB_PASSWORD}

Amazon ECR(弹性容器注册表)

Trivy使用AWS SDK。你不需要安装aws CLI工具。你可以使用AWS CLI的ENV Vars。

GCR(谷歌容器注册表)

Trivy使用Google Cloud SDK。你不需要安装gcloud命令。

如果你想使用目标项目的存储库,可以通过GOOGLE_APPLICATION_CREDENTIAL设置。

# must set TRIVY_USERNAME empty char
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credential.json

自托管注册表(BasicAuth)

BasicAuth服务器需要TRIVY_USERNAME和TRIVY_PASSWORD。

export TRIVY_USERNAME={USERNAME}
export TRIVY_PASSWORD={PASSWORD}

# if you want to use 80 port, use NonSSL
export TRIVY_NON_SSL=true

漏洞检测

系统软件包

未修复/不可修复的漏洞意味着尚未在其分发中提供该修补程序。

系统 支持版本 目标软件包 检测未修复的漏洞
Alpine Linux 2.2 – 2.7, 3.0 – 3.10 Installed by apk NO
Red Hat Universal Base Image 7, 8 Installed by yum/rpm YES
Red Hat Enterprise Linux 6, 7, 8 Installed by yum/rpm YES
CentOS 6, 7 Installed by yum/rpm YES
Debian GNU/Linux wheezy, jessie, stretch, buster Installed by apt/apt-get/dpkg YES
Ubuntu 12.04, 14.04, 16.04, 18.04, 18.10, 19.04 Installed by apt/apt-get/dpkg YES

应用程序依赖项

Trivy会自动检测容器中的以下文件,并扫描应用程序依赖项中的漏洞。

Gemfile.lock

Pipfile.lock

poetry.lock

composer.lock

package-lock.json

yarn.lock

Cargo.lock

这些文件的路径不重要。

示例:https://npm.pkg.github.com/knqyf263/trivy-ci-test/blob/master/Dockerfile

使用

NAME:

请参阅电子表格了解有关详情

在这种情况下,所有漏洞扫描器检测到的漏洞的联合将用作数据集。

注意:

可能存在所有扫描程序都无法检测到的漏洞。

可能存在误报,因为我已手动进行了确认。

Alpine Linux

使用Alpine Linux 3.7.1的composer:1.7.2结果(截至2019/05/12)。

3.png

Trivy具有较高的精确度,而GCR没有检测到任何的漏洞。虽然Docker Hub有许多True Positive,但它也存在很多误报。

RHEL/CentOS

使用CentOS 7.6.1810的crate:3.2.2结果(截至2019/05/14)。

以下图表仅包含可修复的漏洞。

4.png

大多数扫描程序仅检测RHEL/CentOS上的修补/可修复的漏洞,但Trivy还会检测未修补/无法修复的漏洞。

此图还包括无法修复的漏洞。

其他系统

在其他OS的情况下,结果类似于其他容器扫描程序。

vs Clair

Clair使用alpine-secdb。但该数据库的目的是知道哪些包具有backport的修复。正如README描述的那样,它不是Alpine中所有安全问题的完整数据库。

Trivy从Alpine Linux Redmine收集Alpine Linux中的漏洞信息。然后,这些漏洞将被保存在vuln-list上。

alpine-secdb有6959个漏洞(截至2019/05/12)。vuln-list有11101个与Alpine Linux相关的漏洞(截至2019/05/12)。检测准确性存在差异,因为漏洞数量几乎翻了一番。

此外,Trivy还分析了中间层,并找出了哪个版本的库用于静态链接。

Clair无法处理以下情况,因为它在应用所有图层后分析图像。

RUN apk add --no-cache sqlite-dev \
 && wget https://xxx/yyy.tar.gz \
 && tar zxvf yyy.tar.gz && cd yyy \
 && make && make install \
 && apk del sqlite-dev

正如许多人所知,很难选择Clair客户端,因为很多客户都被弃用了。

最后,Trivy还可以检测应用程序相关库中的漏洞,例如Bundler,Composer,Pipenv等。

vs Anchore Engine

与Clair类似,Alpine Linux的检测准确度也有所不同。Anchore Engine不会检测RHEL/CentOS上的无法修复的漏洞,而Trivy则会进行检测。

此外,Anchore Engine需要一些额外操作才能开始扫描。Trivy则更容易使用。

vs Quay,Docker Hub,GCR

由于Quay在内部使用Clair,因此它具有与Clair相同的精确度。Docker Hub只能扫描官方镜像。GCR几乎无法检测到Alpine Linux上的漏洞。此外,它还被锁定到了特定的注册表。

无论注册表如何,都可以使用Trivy。而且它也很容易与CI/CD服务集成。
