CVE-2023-34414

3.1 · LOW

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.

Published Jun 19, 2023CWE-295EPSS 0.90%

Overview

CVE-2023-34414 is a low-severity vulnerability. It was published on June 19, 2023 and has a CVSS 3.1 base score of 3.1 (LOW).

This vulnerability has a CVSS 3.1 base score of 3.1, rated LOW. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
