• CVE-2014-7189
• Affects: crypto/tls
• Published: May 25, 2022
• Modified: Jun 12, 2023

When SessionTicketsDisabled is enabled, crypto/tls allowed man-in-the-middle attackers to spoof clients via unspecified vectors. If the server enables TLS client authentication using certificates (this is rare) and explicitly sets SessionTicketsDisabled to true in the tls.Config, then a malicious client can falsely assert ownership of any client certificate it wishes.
