CVSS: 6.5EPSS: 0%CPEs: 6EXPL: 0CVE-2023-6209 – Mozilla: Incorrect parsing of relative URLs starting with "///"
https://notcve.org/view.php?id=CVE-2023-6209
Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal "/../" part in the path could be used to override the specified host. This could contribute to security problems in web sites. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5. Las URL relativas que comenzaban con tres barras se analizaban incorrectamente y se podía utilizar una parte de path-traversal "/../" en la ruta para anular el host especificado. Esto podría contribuir a problemas de seguridad en los sitios web. • https://bugzilla.mozilla.org/show_bug.cgi?id=1858570 https://lists.debian.org/debian-lts-announce/2023/11/msg00017.html https://lists.debian.org/debian-lts-announce/2023/11/msg00030.html https://www.debian.org/security/2023/dsa-5561 https://www.mozilla.org/security/advisories/mfsa2023-49 https://www.mozilla.org/security/advisories/mfsa2023-50 https://www.mozilla.org/security/advisories/mfsa2023-52 https://access.redhat.com/security/cve/CVE-2023-6209 https://bugzilla.redhat.com/ • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 0CVE-2023-6206 – Mozilla: Clickjacking permission prompts using the fullscreen transition
https://notcve.org/view.php?id=CVE-2023-6206
The black fade animation when exiting fullscreen is roughly the length of the anti-clickjacking delay on permission prompts. It was possible to use this fact to surprise users by luring them to click where the permission grant button would be about to appear. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5. La animación de desvanecimiento negro al salir de la pantalla completa es aproximadamente la duración del retraso anti-clickjacking en las solicitudes de permiso. Era posible utilizar este hecho para sorprender a los usuarios atrayéndolos a hacer clic en el lugar donde el botón de concesión de permiso estaría a punto de aparecer. • https://bugzilla.mozilla.org/show_bug.cgi?id=1857430 https://lists.debian.org/debian-lts-announce/2023/11/msg00017.html https://lists.debian.org/debian-lts-announce/2023/11/msg00030.html https://www.debian.org/security/2023/dsa-5561 https://www.mozilla.org/security/advisories/mfsa2023-49 https://www.mozilla.org/security/advisories/mfsa2023-50 https://www.mozilla.org/security/advisories/mfsa2023-52 https://access.redhat.com/security/cve/CVE-2023-6206 https://bugzilla.redhat.com/ • CWE-1021: Improper Restriction of Rendered UI Layers or Frames •
