Mozilla Firefox before 3.0.11 and SeaMonkey before 1.1.17 associate local documents with external domain names located after the file:// substring in a URL, which allows user-assisted remote attackers to read arbitrary cookies via a crafted HTML document, as demonstrated by a URL with file://example.com/C:/ at the beginning. Mozilla Firefox anteriores a v3.0.11 y SeaMonkey anteriores a v1.1.17 asocian documentos locales con un dominio de nombres externo localizado después de la subcadena "file://" en una URL, lo que permite a atacantes remotos ayudados por el usuario leer cookies de forma arbitraria a través de un documento HTML manipulado, como se demostró mediante una URL con file://examplo.com/C:/ al principio. • http://osvdb.org/55161 http://rhn.redhat.com/errata/RHSA-2009-1096.html http://secunia.com/advisories/35331 http://secunia.com/advisories/35415 http://secunia.com/advisories/35428 http://secunia.com/advisories/35431 http://secunia.com/advisories/35439 http://secunia.com/advisories/35468 http://secunia.com/advisories/35561 http://secunia.com/advisories/35882 http://slackware.com/security/viewer.php?l=slackware-security&y=2009&m=slackware-security.372468 http://slackware.com&# • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Mozilla Firefox before 3.0.11, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.17 use the HTTP Host header to determine the context of a document provided in a non-200 CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack. Mozilla Firefox anteriores a v3.0.11, Thunderbird anteriores a v2.0.0.22, y SeaMonkey anteriores a v1.1.17 utilizan la cabecera HTTP del servidor para determinar el contexto de un documento facilitado mediante una respuesta CONNECT no 200 desde un servidor proxy, lo que permite a atacantes "man-in-the-middle" ejecutar secuencias de comandos web arbitrarios mediante la modificación de la respuesta CONNECT, también conocido como ataque "forzado SSL". • http://osvdb.org/55160 http://research.microsoft.com/apps/pubs/default.aspx?id=79323 http://research.microsoft.com/pubs/79323/pbp-final-with-update.pdf http://secunia.com/advisories/35331 http://secunia.com/advisories/35415 http://secunia.com/advisories/35431 http://secunia.com/advisories/35439 http://secunia.com/advisories/35440 http://secunia.com/advisories/35468 http://secunia.com/advisories/35536 http://secunia.com/advisories/35561 http://secunia.com/advisories/35602 • CWE-287: Improper Authentication •
