The Chrome Object Wrapper (COW) implementation in Mozilla Firefox prior to 18.0, Firefox ESR 17.x prior to 17.0.2, Thunderbird prior to 17.0.2, Thunderbird ESR 17.x prior to 17.0.2, and SeaMonkey prior to 2.15 does not prevent modifications to the prototype of an object, which allows remote malicious users to execute arbitrary JavaScript code with chrome privileges by referencing Object.prototype.__proto__ in a crafted HTML document.

This exploit gains remote code execution on Firefox 17 and 17.0.1, provided the user has installed Flash. No memory corruption is used. First, a Flash object is cloned into the anonymous content of the SVG "use" element in the (CVE-2013-0758). From there, the Flash object can navigate a child frame to a URL in the chrome:// scheme. Then a separate exploit (CVE-2013-0757) is used to bypass the security wrapper around the child frame's window reference and inject code into the chrome:// context. Once we have injection into the chrome execution context, we can write the payload to disk, chmod it (if posix), and then execute. Note: Flash is used here to trigger the exploit but any Firefox plugin with script access should be able to trigger it.
