CVSS: 7.5EPSS: 0%CPEs: 22EXPL: 1CVE-2017-7787 – Mozilla: Same-origin policy bypass with iframes through page reloads (MFSA 2017-19)
https://notcve.org/view.php?id=CVE-2017-7787
Same-origin policy protections can be bypassed on pages with embedded iframes during page reloads, allowing the iframes to access content on the top level page, leading to information disclosure. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55. Las protecciones de política del mismo origen se pueden omitir en páginas con iframes embebidos durante la recarga de páginas, lo que permite que los iframes accedan a contenido en la página de nivel más alto, lo que conduce a una divulgación de información. La vulnerabilidad afecta a Thunderbird en versiones anteriores a la 52.3, Firefox ESR en versiones anteriores a la 52.3 y Firefox en versiones anteriores a la 55. • http://www.securityfocus.com/bid/100234 http://www.securitytracker.com/id/1039124 https://access.redhat.com/errata/RHSA-2017:2456 https://access.redhat.com/errata/RHSA-2017:2534 https://bugzilla.mozilla.org/show_bug.cgi?id=1322896 https://security.gentoo.org/glsa/201803-14 https://www.debian.org/security/2017/dsa-3928 https://www.debian.org/security/2017/dsa-3968 https://www.mozilla.org/security/advisories/mfsa2017-18 https://www.mozilla.org/security/advisories/mfsa2017-19 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-863: Incorrect Authorization •
