The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-e5859237ff advisory.
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. (CVE-2023-34414)
When choosing a site-isolated process for a document loaded from a data: URL that was the result of a redirect, Firefox would load that document in the same process as the site that issued the redirect. This bypassed the site-isolation protections against Spectre-like attacks on sites that host an open redirect. Firefox no longer follows HTTP redirects to data: URLs. This vulnerability affects Firefox < 114. (CVE-2023-34415)
Memory safety bugs present in Firefox 113, Firefox ESR 102.11, and Thunderbird 102.12. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 102.12, Firefox < 114, and Thunderbird < 102.12. (CVE-2023-34416)
Memory safety bugs present in Firefox 113. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 114. (CVE-2023-34417)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
