CVE-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 •
