CVE-2023-34414

Disclosure Date: June 19, 2023
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

The error page for sites with invalid TLS certificates was missing the
activation-delay Firefox uses to protect prompts and permission dialogs
from attacks that exploit human response time delays. If a malicious
page elicited user clicks in precise locations immediately before
navigating to a site with a certificate error and made the renderer
extremely busy at the same time, it could create a gap between when
the error page was loaded and when the display actually refreshed.
With the right timing the elicited clicks could land in that gap and
activate the button that overrides the certificate error for that site. This vulnerability affects Firefox ESR < 102.12, Firefox < 114, and Thunderbird < 102.12.
