Introduction

OpenSCA is intended for scanning third-party dependencies, vulnerabilities and licenses.

Detection Ability

OpenSCA is now capable of parsing configuration files in the listed programming languages and correspondent package managers. The team is now dedicated to introducing more languages and enriching the parsing of relevant configuration files gradually.

LANGUAGE	PACKAGE MANAGER	FILE
Java	Maven	pom.xml
Java	Gradle	.gradle .gradle.kts
JavaScript	Npm	package-lock.json package.json yarn.lock
PHP	Composer	composer.json composer.lock
Ruby	gem	gemfile.lock
Golang	gomod	go.mod go.sum Gopkg.toml Gopkg.lock
Rust	cargo	Cargo.lock
Erlang	Rebar	rebar.lock
Python	Pip	Pipfile Pipfile.lock setup.py requirements.txt requirements.in(For the latter two, pipenv environment & internet connection are needed)

Download & Deployment

1. Download the appropriate executable file according to your system architecture from releases.

2. Or download the source code and compile (go 1.18 and above is needed)

   // github linux/mac
   git clone https://github.com/XmirrorSecurity/OpenSCA-cli.git opensca && cd opensca && go build
   // gitee linux/mac
   git clone https://gitee.com/XmirrorSecurity/OpenSCA-cli.git opensca && cd opensca && go build
   // github windows
   git clone https://github.com/XmirrorSecurity/OpenSCA-cli.git opensca ; cd opensca ; go build
   // gitee windows
   git clone https://gitee.com/XmirrorSecurity/OpenSCA-cli.git opensca ; cd opensca ; go build

   The default option is to generate the program of the current system architecture. If you want to try it for other system architectures, you can set the following environment variables before compiling.

   • Disable CGO_ENABLED CGO_ENABLED=0
   • Set the operating system GOOS=${OS} \\ darwin,liunx,windows
   • Set the architecture GOARCH=${arch} \\ amd64,arm64

Use OpenSCA

Parameters

PARAMETER	TYPE	Descripation	SAMPLE
config	string	Set the path of the configuration file	-config config.json
path	string	Set the path of the target file or directory	-path ./foo
out	string	Save the result to the specified file whose format is defined by the suffix	-out out.json, out.html
log	string	Specify the path of log file	-log my_log.txt
token	string	Cloud service verification from our offical website	-token xxx
proj	string	SaaS project token to sync report with OpenSCA SaaS	-proj xxx

From v3.0.0, apart from these parameters available for CMD/CRT, there are also others for different requirements which have to be set in the configuration file.

Full introduction about each parameters can be found in config.json

v3.0.2 and above allows OpenSCA-cli to snyc reports with OpenSCA SaaS (via proj), so that all reports of multiple projects can be managed together.

If the configuration parameter conflicts with the command-line input parameter, the latter will be taken.

When there's no configuration file in the set path, one in default settings will be generated there.

If no path of configuration file is set, the following ones will be checked:

1. config.json under the working directory
2. opensca_config.json under the user directory
3. config.json under opensca-cli directory

From v3.0.0, url has been put in the configuration file. The default set goes to our cloud vulnerability database. Other online database in accordance with our database structure can also be set through configuration file.

Using previous versions to connect the cloud databse will still need the setting of url, which could be done via both CMD and configuration file. Example: -url https://opensca.xmirror.cn

Report Formats

Files supported by the out parameter are listed below：

TYPE	FORMAT	SPECIFIED SUFFIX	VERSION
REPORT	json	.json	*
	xml	.xml	*
	html	.html	v1.0.6 and above
	sqlite	.sqlite	v1.0.13 and above
	csv	.csv	v1.0.13 and above
	sarif	.sarif
SBOM	spdx	.spdx .spdx.json .spdx.xml	v1.0.8 and above
	cdx	.cdx.json .cdx.xml	v1.0.11and above
	swid	.swid.json .swid.xml	v1.0.11and above
	dsdx	.dsdx .dsdx.json .dsdx.xml	v3.0.0and above

Sample

# Use opensca-cli to scan with CMD parameters:
opensca-cli -path ${project_path} -config ${config_path} -out ${filename}.${suffix} -token ${token}

# Start scanning after setting down the configuration file:
opensca-cli

Scan & Report via Docker Container

# Detect dependencies in the current directory:
docker run -ti --rm -v ${PWD}:/src opensca/opensca-cli

# Connect to the cloud vulnerability database:
docker run -ti --rm -v ${PWD}:/src opensca/opensca-cli -token ${put_your_token_here}

You can also use the configuration file for advanced settings. Save config.json to the mounted directory of src or set other paths within the container through -config. The writing method for mounting the current directory on different terminals varies, we list common ones here FYI:

terminal	pwd
bash	$(pwd)
zsh	${PWD}
cmd	%cd%
powershell	(Get-Location).Path

FAQ

Is the environment variable needed while using OpenSCA?

No. OpenSCA can be directly executed by the command in CLI/CRT after decompression.

About the vulnerability database?

OpenSCA allows configuring the local vulnerability database. It has to be sorted according to the Format of the Vulnerability Database File.

Meanwhile, OpenSCA also offers a cloud vulnerability database covering official databases including CVE/CWE/NVD/CNVD/CNNVD.

About the time cost of OpenSCA scanning?

It depends on the size of the package, the network condition and the language.

From v1.0.11, we add aliyun mirror database as the backup to the official maven repository to solve the lag caused by network connection.

For v1.0.10 and below, if the time is abnormally long and error information about connection failure to the maven repository gets reported in the log file, users of versions between v1.0.6 and v1.0.10 can fix the problem by setting the maven field in config.json like below:

{
    "maven": [
        {
            "repo": "https://maven.aliyun.com/repository/public",
            "user": "",
            "password": ""
        }
    ]
}   

After setting, save config.json to the same folder of opensca-cli.exe and execute the command. Eg:

opensca-cli -token {token} -path {path} -out output.html -config config.json

Users of v1.0.5 and below may have to modify the source code. We recommend an upgrade to higher versions.
