Infosec: Seeking advice regarding CVSS scoring.

One of the hardest tasks in my dayjob (at WPScan.com) is to assign CVSS scores. Particularly the Availability impact metric is a source of internal arguments. Personally I think the CVSS v3.1 Users Guide is quite clear on the subject, but we still end up arguing how this should be understood in the context of WordPress plugins.

Typically the argument is that if a vulnerability lets an attacker upload arbitrary files or execute arbitrary code, that amounts to a high impact on availability. The way I read the CVSS docs, this would only affect the Confidentiality and Integrity impact metrics, leaving Availability at None or at most Low.

Does anybody have any advice or insights into how we should understand and score this metric?

I've written about a vulnerability I've been researching at work. Forking your dependencies without really knowing what you do may cause unintended consequences. If your project happens to be a WordPress plugin, you may risk that it appears on our blog. Don't appear on our blog!

I recommend anyone who wants a solid intro to finding and exploiting weaknesses in C and C++ code to check out the training from @Patricia@social.vivaldi.net at NDC-security in Oslo in January!

I’ve adjusted my training to be targeted towards security professionals who want hands-on experience with binary exploitation and vulnerabilities.

Cool to see my work mentioned in a conference talk by @{https://mastodon.technology/@rysiek}. It was a very interesting talk too, definitely one to check out for the more technically inclined people interested in a more decentralised and open web!
