CVSS library for working with CVSS version 2 scores and base vectors
Easily parse base vector components from a CVSS2 string:
In []: from cvss import cvss
In []: bv = cvss.BaseVector('AV:N/AC:L/Au:N/C:N/I:N/A:P')
In []: bv.av
Out[]: 'N'
In []: bv.au
Out[]: 'N'
Or constuct an instance of BaseVector from the components:
In []: bv = cvss.from_base_metrics('n', 'l', 'n', 'n', 'p', 'c')
Test for validity:
In []: cvss.valid_vector('AV:N/AC:L/Au:N/C:N/I:N/A:H')
Out[]: False
Calculate the base score:
In []: bv.base_score
Out[]: Decimal('5.0')
Calculate the NVD severity based on the base score:
In []: bv.severity
Out[]: 'Medium'
