MatLab classes to deal with CVSS 2 and CVSS 3.

CVSS for MatLab

This package contains MatLab classes to manipulate CVSS 2 and CVSS 3. You can load a CVSS string into an instance of a CVSS class, and call methods to calculate the base score, the temporal score and the environmental score. It is also possible to manipulate a CVSS instance to add or change values.

Example

c = CVSS2.Parse_Metrics_String('AV:N/AC:L/Au:N/C:N/I:N/A:C');
s = c.Base_Score;

btc = c.Fill_Parse('E:U/RL:OF/RC:UC');  % best temporal parameters
bts = c.Temporal_Score;                 % get the best temporal score

Au = c.Au; % getting one of the CVSS parameters value (not the string)

Optimizations

CVSS for MatLab was optimized by using the MatLab profiler to indicate slow methods. The slowest ones were refactored by reducing the number of loops, and even one of them was replaced by an equivalent C coded function: strsplit.c. You will need to run mex strsplit.c before running to compile it.

More can be optimized, it's a work in progress.

Tests

You can trust this package. More and more tests will be added so that bugs stay away from the code.
