CVSS: 7.1EPSS: 0%CPEs: 15EXPL: 0CVE-2018-12397 – Mozilla: WebExtension local file permission check bypass
https://notcve.org/view.php?id=CVE-2018-12397
A WebExtension can request access to local files without the warning prompt stating that the extension will "Access your data for all websites" being displayed to the user. This allows extensions to run content scripts in local pages without permission warnings when a local file is opened. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63. WebExtensions pueden solicitar el acceso a archivos locales sin que salte un aviso de advertencia en el que consta que la extensión accederá a sus datos para todo sitio web, mostrándose así al usuario. Esto permite que las extensiones ejecuten scripts de contenido en páginas locales sin advertencias de permisos al abrir un archivo local. • http://www.securityfocus.com/bid/105718 http://www.securitytracker.com/id/1041944 https://access.redhat.com/errata/RHSA-2018:3005 https://access.redhat.com/errata/RHSA-2018:3006 https://bugzilla.mozilla.org/show_bug.cgi?id=1487478 https://lists.debian.org/debian-lts-announce/2018/11/msg00008.html https://security.gentoo.org/glsa/201811-04 https://usn.ubuntu.com/3801-1 https://www.debian.org/security/2018/dsa-4324 https://www.mozilla.org/security/advisories/mfsa2018-26&# • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-862: Missing Authorization •
CVSS: 7.5EPSS: 0%CPEs: 15EXPL: 0CVE-2018-12395 – Mozilla: WebExtension bypass of domain restrictions through header rewriting
https://notcve.org/view.php?id=CVE-2018-12395
By rewriting the Host: request headers using the webRequest API, a WebExtension can bypass domain restrictions through domain fronting. This would allow access to domains that share a host that are otherwise restricted. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63. Al reescribir las cabeceras "Host: request" que utilizan la API webRequest, WebExtensions pueden omitir las restricciones de dominio mediante la fronting del dominio. Esto permitiría el acceso a dominios, cuyo acceso es normalmente restringido, que comparten un host. • http://www.securityfocus.com/bid/105718 http://www.securitytracker.com/id/1041944 https://access.redhat.com/errata/RHSA-2018:3005 https://access.redhat.com/errata/RHSA-2018:3006 https://bugzilla.mozilla.org/show_bug.cgi?id=1467523 https://lists.debian.org/debian-lts-announce/2018/11/msg00008.html https://security.gentoo.org/glsa/201811-04 https://usn.ubuntu.com/3801-1 https://www.debian.org/security/2018/dsa-4324 https://www.mozilla.org/security/advisories/mfsa2018-26&# • CWE-284: Improper Access Control •

A vulnerability where the JavaScript JIT compiler inlines Array.prototype.push with multiple arguments that results in the stack pointer being off by 8 bytes after a bailout. This leaks a memory address to the calling function which can be used as part of an exploit inside the sandboxed content process. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3. Vulnerabilidad por la cual el compilador JIT de JavaScript inserta Array.prototype.push con múltiples argumentos que resultan en que el puntero de la pila está fuera de su sitio por 8 bytes tras un bailout.

Windows 10 does not warn users before opening executable files with the SettingContent-ms extension even when they have been downloaded from the internet and have the "Mark of the Web." Without the warning, unsuspecting users unfamiliar with this new file type might run an unwanted executable. This also allows a WebExtension with the limited downloads.open permission to execute arbitrary code without user interaction on Windows 10 systems. *Note: this issue only affects Windows operating systems. Other operating systems are unaffected.*. • http://www.securityfocus.com/bid/104560 http://www.securitytracker.com/id/1041193 https://bugzilla.mozilla.org/show_bug.cgi?id=1468217 https://posts.specterops.io/the-tale-of-settingcontent-ms-files-f1ea253e4d39 https://security.gentoo.org/glsa/201810-01 https://www.mozilla.org/security/advisories/mfsa2018-15 https://www.mozilla.org/security/advisories/mfsa2018-16 https://www.mozilla.org/security/advisories/mfsa2018-17 https://www.mozilla.org/security/advisories/mfsa2018-18 https://www&# •
