A collection of tools for working with National Vulnerability Database feeds.
The HOWTO provides a broader view on how to effectively use these tools.
- Go 1.13 or newer
You need a properly setup Go environment.
For Go 1.13 - 1.14:
go get github.com/facebookincubator/nvdtools/...
cd "$GOPATH"/src/github.com/facebookincubator/nvdtools/cmd
go install ./...From Go 1.15 onwards, modules are not downloaded to GOPATH, but to GOMODCACHE. It is recommended to clone the repo and run run go install from there instead:
git clone https://github.com/facebookincubator/nvdtools
cd nvdtools
go install ./...From Go 1.17 onwards, go get is deprecated. go install is used instead to download the module to the cache and install it:
go install github.com/facebookincubator/nvdtools/...@latestgo mod init github.com/facebookincubator/nvdtools
go mod tidy
make
cp build/bin/* ~/go/bin/
cpe2cve is a command line tool for scanning an inventory of CPE names for vulnerabilities.
It expects a stream of lines of delimiter-separated fields, one of these fields being a delimiter-separated list of CPE names in the inventory.
Vulnerability feeds should be provided as arguments to the program in JSON format.
Output is a stream of delimiter-separated input value decorated with a vulnerability ID (CVE) and a delimiter-separated list of CPE names that match this vulnerability.
Unwanted input fields could be erased from the output with -e option.
Input and output delimiters can be configured with -d, -d2, -o an -o2 options.
The column to which output the CVE and matches for that CVE can be configured with -cve and -matches options correspondingly.

-cpe_part-- identifies the class of a product: h for hardware, a for application and o for OS-cpe_vendor-- identifies the person or organisation that manufactured or created the product-cpe_product-- describes or identifies the most common and recognisable title or name of the product-cpe_version-- vendor-specific alphanumeric strings characterising the particular release version of the product-cpe_update-- vendor-specific alphanumeric strings characterising the particular update, service pack, or point release of the product-cpe_edition-- capture edition-related terms applied by the vendor to the product; this attribute is considered deprecated in CPE specification version 2.3 and it should be assigned the logical value ANY except where required for backward compatibility with version 2.2 of the CPE specification.-cpe_swedition-- characterises how the product is tailored to a particular market or class of end users-cpe_targetsw-- characterises the software computing environment within which the product operates-cpe_targethw-- characterises the software computing environment within which the product operates-cpe_language-- defines the language supported in the user interface of the product being described; must be valid language tags as defined by [RFC5646]-cpe_other-- any other general descriptive or identifying information which is vendor- or product-specific and which does not logically fit in any other attribute value
Omitted parts of the CPE name defaults to logical value ANY, as per specification
Optional flag -lower brings the strings to lower case.

cpe:/a:microsoft:internet_explorer:8.1:sp1:-fireeye2nvd downloads the vulnerability data from FireEye and converts it into NVD format. The resulting file can be used as a feed in cpe2cve processor
flexera2nvd downloads the vulnerability data from Flexera and converts it into NVD format. The resulting file can be used as a feed in cpe2cve processor
idefense2nvd downloads the vulnerability data from Idefense and converts it into NVD format. The resulting file can be used as a feed in cpe2cve processor
nvdsync synchronizes NVD data feeds to local directory; it checks the hashes of the files against the ones provided by NVD and only updates the changed files.
rpm2cpe takes a delimiter-separated input with one of the fields containing RPM package name and produces delimiter-separated output consisting of the same fields plus CPE name parsed from RPM package name.
echo openoffice-eu-writer-4.1.5-9789.i586.rpm | rpm2cpe -rpm=1 -cpe=2 -e=1
cpe:/a::openoffice-eu-writer:4.1.5:9789:~~~~i586~rustsec2nvd converts the vulnerabilities from the Rustsec Advisory-DB into NVD format. The resulting file can be used as a feed in cpe2cve processor
snyk2nvd downloads the vulnerability data from Snyk and converts it into NVD format. The resulting file can be used as a feed in cpe2cve processor
vfeed2nvd converts the vulnerability data from vFeed into NVD format. The resulting file can be used as a feed in cpe2cve processor
vulndb is a command line tool to manage NVD-like vulnerability databases, backed by MySQL.
Supports NVD CVE JSON 1.0 feeds. Data is versioned, organized by provider names and grouped by vendor, custom, and snoozes datasets:
- Vendor dataset: read-only CVE feeds we continuously import.
- Custom dataset: allows to overwrite CVEs from vendor data with custom data during exports
- Snooze dataset: user-defined CVE and metadata with deadline, used for remediation automation
See vulndb help for details.
Implementation of CVSS v2 specification which provides functions for serializing and deserializing vectors as well as score calculation.
Implementation of CVSS v3 specification which provides functions for serializing and deserializing vectors as well as score calculation.
