[Servercert-wg] Voting begins for Ballot SC45: Wildcard Domain Validation

[Ryan Sleevi]

This email begins the voting period for Ballot SC45: Wildcard Domain
Validation

Purpose of Ballot:

This Ballot addresses security issues with the use of methods 3.2.2.4.6,
3.2.2.4.18, and 3.2.2.4.19 of the Baseline Requirements to authenticate an
entire domain namespace. These methods rely on an HTTP based demonstration
of control, which only demonstrates control over a particular host and
service, rather than the entire Domain Namespace.

Effective 2021-12-01, these methods MUST NOT be used to issue Wildcard
Certificates and MUST NOT be used as Authorization Domain Names for
subordinate FQDNs of the validated FQDN.

Although not directly modifying the same section, this Ballot does interact
with Ballot SC42: 398-day Re-use Period, and so two versions are presented,
based on whether or not SC42 finishes the IP review period without issues.
If SC42 is adopted, 3.2.2.4.6 does not need to change, because no past
validations can be reused to issue new certificates after the effective
date. However, if SC42 were to fail, 3.2.2.4.6 is also modified to keep
consistent with .18 and .19.

The following motion has been proposed by Ryan Sleevi of Google and
endorsed by Jos Purvis of Cisco and Dimitris Zacharopoulos of HARICA.
