go-cpe-dictionary

This is tool to build a local copy of the CPE (Common Platform Enumeration) [1].

CPE is a structured naming scheme for information technology systems, software, and packages. Based upon the generic syntax for Uniform Resource Identifiers (URI), CPE includes a formal name format, a method for checking names against a system, and a description format for binding text and tests to a name.

go-cpe-dictionary download CPE data from NVD (National Vulnerabilities Database) [2]. Copy is generated in sqlite format.

Install requirements

go-cpe-dictionary requires the following packages.

• sqlite
• git
• gcc
• go v1.7 or later
  • https://golang.org/doc/install

$ sudo yum -y install sqlite git gcc
$ wget https://storage.googleapis.com/golang/go1.14.2.linux-amd64.tar.gz
$ sudo tar -C /usr/local -xzf go1.14.2.linux-amd64.tar.gz
$ mkdir $HOME/go

Put these lines into /etc/profile.d/goenv.sh

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

Set the OS environment variable to current shell

$ source /etc/profile.d/goenv.sh

Deploy go-cpe-dictionary

To install:

$ mkdir -p $GOPATH/src/github.com/vulsio
$ cd $GOPATH/src/github.com/vulsio
$ git clone https://github.com/vulsio/go-cpe-dictionary.git
$ cd go-cpe-dictionary
$ make install

Fetch CPE data from NVD. It takes about 1 minutes.

$ go-cpe-dictionary fetch nvd
... snip ...
$ ls -alh cpe.sqlite3
-rw-r--r-- 1 ec2-user ec2-user 7.0M Mar 24 13:20 cpe.sqlite3

Now we have a local copy of CPE data in sqlite3.

How to search CPE name by application name

This example use Peco for incremental search.

$ ls cpe.sqlite3
cpe.sqlite3
$ sqlite3 ./cpe.sqlite3 'select cpe_uri from categorized_cpes' | peco
