RE: CVE for hosted services

just for the sake of 'argument', and more of an exercise to see what 
is leading to.


Harold, how would you write a CVE-ish description of this, in the 
of moving CVE to site-specific issues? The service and info disclosed 
the easy part. Then what? Do you also mention some of the services that 
use Cloudflare? Some businesses may know, where individuals do not 
1Password is hosted on it). What date range do you put down for this? 
know the fix date, but not the start date. This goes back to the 
of making such entries useful to companies trying to determine risk.

In many ways, this entry would be one of the easiest to write given the 
details, and yet lacks a critical bit of info.

: A popular service/site has a vulnerability for some period of time. 
This vulnerability created an exposure for users/consumers of the 
service/site. The users/consumers would like to go back and determine 
if they have been impacted because of this exposure. In order to do 
this they will need a date range and a description of the problem (i.e. 
what part of the service was vulnerable), potential impacts on them 
(the users), and potential (or actual) exploits. While it would be 
beneficial if the service provider had all of this information, they 
may not, and now there is a need to have a long-lived identifier to 
coordinate the discussion among several different stakeholders (I would 
also argue that just communicating between the service provider and the 
customer is enough reason for the identifier). I agree collecting this 
information may not be easy at the moment, but I don't think that 
doesn't mean it isn't desirable to have it. Minimally, I think this use 
case demonstrates t
 he need for an identifier. Perhaps once it is demonstrated that this 
information is important then it will be more routine for it to be 
tracked and available.

: Agreed, there's likely pain for cataloging purposes (de-duplication) 
and low value for engineering purposes.  But the overriding factor for 
me is
: *identification* (and yes, for ID to work, it has to be possible to 
distinguish different vulnerabilities).
: CVE throws light on vulnerabilities.  Probably weekly, without 
looking, I come across issues that don't have CVE IDs assigned and 
therefore aren't noticed by people who might benefit from knowing.  I 
make a note to send in a minimum viable entry, but haven't yet.
: Oh, services have CVEs?  Airplanes?  Dentist office software?  Oh, 
large services freely admit they have vulnerabilities, and fix them?
: Users/customers actually like such transparency?
: Vulnerabilities are common and everywhere and aren't terribly special 
individually.  Name them and go about your choice of defensive 
activities, probably including vulnerability management.
