  • Look for requests matching /*.swf$ from a Firefox 17.x User-Agent, which may indicate delivery of the exploit's Flash trigger payload.
  • Detect SVG 'use' element href being set to the current page location with a fragment (e.g., location.href + '#a'), which is the mechanism used to clone the plugin object into anonymous SVG content.
  • Detect attempts to overwrite __proto__ on a frame's prototype to an object exposing 'setTimeout' and 'call', which is the CVE-2013-0757 wrapper bypass step chained with this CVE.
  • The exploit navigates a child frame to a chrome:// URL via a cloned Flash plugin object inside an SVG 'use' element; monitor for child frame navigations to chrome:// scheme from web content.
  • The exploit delivers an HTML page with an embedded object, a base tag, and an SVG use element; look for responses containing all three together targeting Firefox 17.x clients.
  • ·The exploit targets only Firefox 17.0 and 17.0.1 with Flash installed; it does not use memory corruption and requires JavaScript to be enabled.
  • ·In Thunderbird and SeaMonkey, the flaw cannot be exploited via email because scripting is disabled, but may be exploitable in browser-like contexts.
  • ·Any Firefox plugin with script access (not just Flash) can be used to trigger the SVG plugin cloning vulnerability.
