go-cve-dictionary

This is tool to build a local copy of the NVD (National Vulnerabilities Database) [1] and the Japanese JVN [2], which contain security vulnerabilities according to their CVE identifiers [3] including exhaustive information and a risk score. The local copy is generated in sqlite format, and the tool has a server mode for easy querying.

Installation

Install requirements

go-cve-dictionary requires the following packages.

SQLite3, MySQL, PostgreSQL or Redis
git
gcc
go v1.7.1 or later
- https://golang.org/doc/install

Here's an example for Amazon EC2 server.

$ ssh ec2-user@52.100.100.100  -i ~/.ssh/private.pem
$ sudo yum -y install sqlite git gcc
$ wget https://storage.googleapis.com/golang/go1.7.1.linux-amd64.tar.gz
$ sudo tar -C /usr/local -xzf go1.7.1.linux-amd64.tar.gz
$ mkdir $HOME/go

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

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

Set the OS environment variable to current shell

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

Deploy go-cve-dictionary

To install:

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

Create a log output directory. You can use another directory on the command line option (-log-dir).

$ sudo mkdir /var/log/vuls
$ sudo chown ec2-user /var/log/vuls
$ sudo chmod 700 /var/log/vuls

Fetch vulnerability data from NVD. It takes about 10 minutes (on AWS).

$ for i in `seq 2002 $(date +"%Y")`; do go-cve-dictionary fetchnvd -years $i; done
... snip ...
$ ls -alh cve.sqlite3
-rw-r--r-- 1 ec2-user ec2-user 7.0M Mar 24 13:20 cve.sqlite3

Now we have vulnerability data. Start go-cve-dictionary as server mode.

$ go-cve-dictionary server
[Mar 24 15:21:55]  INFO Opening DB. datafile: /home/ec2-user/cve.sqlite3

[Mar 24 15:21:56]  INFO Listening on 127.0.0.1:1323

Update go-cve-dictionary

If the DB schema was changed, please specify new SQLite3, MySQL, PostgreSQL or Redis DB file.

$ cd $GOPATH/src/github.com/kotakanbe/go-cve-dictionary
$ git pull
$ rm -r vendor
$ make install

Binary files are created under $GOPATH/bin
