CVE-2023-34414
CVSS v2.0
5.0
Medium
| Vector | AV:N/AC:L/Au:N/C:P/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Firefox ESR versions prior to 102.12
Firefox versions prior to 114
Thunderbird versions prior to 102.12
Description
The issue is related to the error page for sites with invalid TLS certificates, which was missing the activation-delay used to protect prompts and permission dialogs from attacks that exploit human response time delays. A malicious page could elicit user clicks in precise locations immediately before navigating to a site with a certificate error, creating 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.
Recommendations
For Firefox ESR versions prior to 102.12, update to version 102.12 or later.
For Firefox versions prior to 114, update to version 114 or later.
For Thunderbird versions prior to 102.12, update to version 102.12 or later.
