ACME TLS-SNI-01 validation disabled due to vulnerability – Incidents – Let’s Encrypt Community Support

Posted by jpluimers on 2018/01/11

Now that so many sites depend on LetsEncrypt: maybe it is time for a second one.

We’ve received a credible report of a problem with ACME TLS-SNI-01 validation which could allow people to get certificates they should not be able to get. While we investigate further we have disabled tls-sni-01 validation. We’ll post more information soon.
