CVSS: 4.3EPSS: 1%CPEs: 5EXPL: 1CVE-2019-11743 – Mozilla: Cross-origin access to unload event attributes
https://notcve.org/view.php?id=CVE-2019-11743
Navigation events were not fully adhering to the W3C's "Navigation-Timing Level 2" draft specification in some instances for the unload event, which restricts access to detailed timing attributes to only be same-origin. This resulted in potential cross-origin information exposure of history through timing side-channel attacks. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1. Los eventos de navegación no se adhirieron totalmente a la especificación borrador del "Navigation-Timing Level 2" de W3C en algunas instancias para el evento de descarga, que restringe el acceso a los atributos de sincronización detallados para que solo sean del mismo origen. Esto resultó en una posible exposición de información de origen cruzado mediante la sincronización de ataques de canal lateral. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1560495 https://security.gentoo.org/glsa/201911-07 https://usn.ubuntu.com/4150-1 https://w3c.github.io/navigation-timing https://www.mozilla.org • CWE-203: Observable Discrepancy CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
CVSS: 4.3EPSS: 0%CPEs: 2EXPL: 0CVE-2019-11749 – Mozilla: Camera information available without prompting using getUserMedia
https://notcve.org/view.php?id=CVE-2019-11749
A vulnerability exists in WebRTC where malicious web content can use probing techniques on the getUserMedia API using constraints to reveal device properties of cameras on the system without triggering a user prompt or notification. This allows for the potential fingerprinting of users. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1. Se presenta una vulnerabilidad en WebRTC donde el contenido web malicioso puede utilizar técnicas de sondeo en la API getUserMedia usando restricciones para revelar las propiedades del dispositivo de las cámaras en el sistema sin la activación de un aviso o notificación de usuario. Esto permite la posible toma de huellas digitales de usuarios. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1565374 https://www.mozilla.org/security/advisories/mfsa2019-25 https://www.mozilla.org/security/advisories/mfsa2019-26 https://access.redhat.com/security/cve/CVE-2019-11749 https://bugzilla.redhat.com/show_bug.cgi?id=1748666 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 6.5EPSS: 0%CPEs: 2EXPL: 0CVE-2019-11748 – Mozilla: Persistence of WebRTC permissions in a third party context
https://notcve.org/view.php?id=CVE-2019-11748
WebRTC in Firefox will honor persisted permissions given to sites for access to microphone and camera resources even when in a third-party context. In light of recent high profile vulnerabilities in other software, a decision was made to no longer persist these permissions. This avoids the possibility of trusted WebRTC resources being invisibly embedded in web content and abusing permissions previously given by users. Users will now be prompted for permissions on each use. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1564588 https://www.mozilla.org/security/advisories/mfsa2019-25 https://www.mozilla.org/security/advisories/mfsa2019-26 https://access.redhat.com/security/cve/CVE-2019-11748 https://bugzilla.redhat.com/show_bug.cgi?id=1748665 • CWE-281: Improper Preservation of Permissions CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 9.3EPSS: 0%CPEs: 3EXPL: 0CVE-2019-9812 – Mozilla Firefox sync Universal Cross-Site Scripting Sandbox Escape Vulnerability
https://notcve.org/view.php?id=CVE-2019-9812
Given a compromised sandboxed content process due to a separate vulnerability, it is possible to escape that sandbox by loading accounts.firefox.com in that process and forcing a log-in to a malicious Firefox Sync account. Preference settings that disable the sandbox are then synchronized to the local machine and the compromised browser would restart without the sandbox if a crash is triggered. This vulnerability affects Firefox ESR < 60.9, Firefox ESR < 68.1, and Firefox < 69. Dado un proceso de contenido comprometido dentro del sandbox debido a una vulnerabilidad separada, es posible escapar de ese sandbox cargando accounts.firefox.com en ese proceso y forzando un inicio de sesión en una cuenta de Firefox Sync maliciosa. La configuración de preferencias que deshabilita el sandbox es sincronizada con la máquina local y el navegador comprometido se reiniciará sin el sandbox si es activado un bloqueo. • https://bugzilla.mozilla.org/show_bug.cgi?id=1538008 https://bugzilla.mozilla.org/show_bug.cgi?id=1538015 https://www.mozilla.org/security/advisories/mfsa2019-25 https://www.mozilla.org/security/advisories/mfsa2019-26 https://www.mozilla.org/security/advisories/mfsa2019-27 https://access.redhat.com/security/cve/CVE-2019-9812 https://bugzilla.redhat.com/show_bug.cgi?id=1748660 • CWE-250: Execution with Unnecessary Privileges •
CVSS: 9.8EPSS: 0%CPEs: 2EXPL: 0CVE-2019-11733 – firefox: stored passwords in 'Saved Logins' can be copied without master password entry
https://notcve.org/view.php?id=CVE-2019-11733
When a master password is set, it is required to be entered again before stored passwords can be accessed in the 'Saved Logins' dialog. It was found that locally stored passwords can be copied to the clipboard thorough the 'copy password' context menu item without re-entering the master password if the master password had been previously entered in the same session, allowing for potential theft of stored passwords. This vulnerability affects Firefox < 68.0.2 and Firefox ESR < 68.0.2. Cuando se establece una contraseña maestra, es necesario ingresarla nuevamente antes de que pueda ser accedida a las contraseñas almacenadas en el cuadro de diálogo "Saved Logins". Se detectó que las contraseñas almacenadas localmente pueden ser copiadas en el portapapeles por medio del elemento del menú contextual "copy password" sin reingresar la contraseña maestra, si la contraseña maestra ha sido ingresada previamente en la misma sesión, permitiendo el robo potencial de contraseñas almacenadas. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1565780 https://www.mozilla.org/security/advisories/mfsa2019-24 https://access.redhat.com/security/cve/CVE-2019-11733 https://bugzilla.redhat.com/show_bug.cgi?id=1745687 • CWE-287: Improper Authentication CWE-306: Missing Authentication for Critical Function •
