To be honest, I am a bit dismayed at the quality of the data. 2001 only categorized 1.7% of the vulns recorded (I am sure most, if not all, were added retroactively). The highest percentage of vulns that had been categorized was 90% in 2008. I find it interesting that the first few years are dominated by buffer overflows (perhaps because of poor data), and then around 2008, web vulns become the top recorded and categorized. Perhaps this is because of the vast amount new web technologies emerging. That is, until 2011 where buffer overflows are once again the most. I used the xml files from the NIST and my source code that I used to generate the stats is on github. Using LINQ, so it isn't super speedy. Takes a few minutes. Works with Mono or .NET.
