CVE-2012-0458 – Mozilla: Escalation of privilege with Javascript: URL as home page (MFSA 2012-16)

https://notcve.org/view.php?id=CVE-2012-0458

Mozilla Firefox before 3.6.28 and 4.x through 10.0, Firefox ESR 10.x before 10.0.3, Thunderbird before 3.1.20 and 5.0 through 10.0, Thunderbird ESR 10.x before 10.0.3, and SeaMonkey before 2.8 do not properly restrict setting the home page through the dragging of a URL to the home button, which allows user-assisted remote attackers to execute arbitrary JavaScript code with chrome privileges via a javascript: URL that is later interpreted in the about:sessionrestore context. Mozilla Firefox antes de v3.6.28 y v4.x hasta v10.0, Firefox ESR v10.x antes de v10.0.3, Thunderbird antes de v3.1.20 y v5.0 hasta v10.0, Thunderbird ESR v10.x antes de v10.0.3, y SeaMonkey antes de v2.8 no restringen adecuadamente establecer la página principal a través del arrastre de una dirección URL hacia el botón de inicio, lo que permite a atacantes remotos asistidos por el usuario ejecutar código JavaScript arbitrario con privilegios de chrome a través de un javascript: URL que luego se interpreta en el ??contexto about:sessionrestore. • http://lists.opensuse.org/opensuse-security-announce/2012-03/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2012-03/msg00015.html http://lists.opensuse.org/opensuse-updates/2012-03/msg00042.html http://rhn.redhat.com/errata/RHSA-2012-0387.html http://rhn.redhat.com/errata/RHSA-2012-0388.html http://secunia.com/advisories/48359 http://secunia.com/advisories/48402 http://secunia.com/advisories/48414 http://secunia.com/advisories/48495 http://secunia.com/advisories • CWE-264: Permissions, Privileges, and Access Controls •
