The navigator.sendBeacon implementation in Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 processes HTTP 30x status codes for redirects after a preflight request has occurred, which allows remote attackers to bypass intended CORS access-control checks and conduct cross-site request forgery (CSRF) attacks via a crafted web site, a similar issue to CVE-2014-8638. La implementación navigator.sendBeacon en Mozilla Firefox anterior a 37.0, Firefox ESR 31.x anterior a 31.6, y Thunderbird anterior a 31.6 procesa los códigos del estatus HTTP 30x para redirecciones después de se ha ocurrido una solicitud de prevuelo, lo que permite a atacantes remotos evadir las comprobaciones de control de acceso a CORS y realizar ataques de CSRF a través de un sitio web manipulado, un problema similar a CVE-2014-8638. A flaw was found in the Beacon interface implementation in Firefox. A web page containing malicious content could allow a remote attacker to conduct a Cross-Site Request Forgery (CSRF) attack. • http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00031.html http://rhn.redhat.com/errata/RHSA-2015-0766.html http://rhn.redhat.com/errata/RHSA-2015-0771.html http://www.debian.org/security/2015/dsa-3211 http://www.debian.org/security/2015/dsa-3212 • CWE-352: Cross-Site Request Forgery (CSRF) •

Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 do not properly restrict resource: URLs, which makes it easier for remote attackers to execute arbitrary JavaScript code with chrome privileges by leveraging the ability to bypass the Same Origin Policy, as demonstrated by the resource: URL associated with PDF.js. Mozilla Firefox anterior a 37.0, Firefox ESR 31.x anterior a 31.6, y Thunderbird anterior a 31.6 no restringe correctamente las URLs resource:, lo que facilita a atacantes remotos ejecutar código JavaScript arbitrario con privilegios chrome mediante el aprovechamiento de la habilidad de evadir Same Origin Policy, tal y como fue demostrado por la URL resource: asociada con PDF.js. A flaw was found in the way documents were loaded via resource URLs in, for example, Mozilla's PDF.js PDF file viewer. An attacker could use this flaw to bypass certain restrictions and under certain conditions even execute arbitrary code with the privileges of the user running Firefox. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. • https://www.exploit-db.com/exploits/37958 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00031.html http://rhn.redhat.com/errata/RHSA-2015-0766.html http://rhn.redhat.com/errata/RHSA-2015-0771.html http://www.debian.org/security/2015/dsa-3211 http&# • CWE-250: Execution with Unnecessary Privileges CWE-264: Permissions, Privileges, and Access Controls •
