CVSS

This Python package contains CVSS v2 and v3 computation utilities and interactive calculator compatible with both Python 2 and Python 3.

The library is tested on all currently-supported Python versions available via GitHub Actions (with the exception of Python 2.7, which is EOL but still tested against), but it is simple enough to run on even older versions.

Installation

# pip install cvss

Usage

Library

from cvss import CVSS2, CVSS3


vector = 'AV:L/AC:L/Au:M/C:N/I:P/A:C/E:U/RL:W/RC:ND/CDP:L/TD:H/CR:ND/IR:ND/AR:M'
c = CVSS2(vector)
print(vector)
print(c.clean_vector())
print(c.scores())

print()

vector = 'CVSS:3.0/S:C/C:H/I:H/A:N/AV:P/AC:H/PR:H/UI:R/E:H/RL:O/RC:R/CR:H/IR:X/AR:X/MAC:H/MPR:X/MUI:X/MC:L/MA:X'
c = CVSS3(vector)
print(vector)
print(c.clean_vector())
print(c.scores())
print(c.severities())

Sample output:

AV:L/AC:L/Au:M/C:N/I:P/A:C/E:U/RL:W/RC:ND/CDP:L/TD:H/CR:ND/IR:ND/AR:M
AV:L/AC:L/Au:M/C:N/I:P/A:C/E:U/RL:W/CDP:L/TD:H/AR:M
(5.0, 4.0, 4.6)

CVSS:3.0/S:C/C:H/I:H/A:N/AV:P/AC:H/PR:H/UI:R/E:H/RL:O/RC:R/CR:H/IR:X/AR:X/MAC:H/MPR:X/MUI:X/MC:L/MA:X
CVSS:3.0/AV:P/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:N/E:H/RL:O/RC:R/CR:H/MAC:H/MC:L
(6.5, 6.0, 5.3)
('Medium', 'Medium', 'Medium')

Interactive calculator

For interactive calculator run the following:

$ cvss_calculator

For help on the calculator options run:

$ cvss_calculator --help

Testing

For extensive testing, the test vectors were generated using official JavaScript generators and cvsslib.

To run all tests use the following script on a system with both Python 2 and Python 3 installed:

$ cd tests
$ bash run_tests.sh
