Vulnerability Note VU#358017
Mozilla Firefox URL protocol handling vulnerability
On Microsoft Windows systems, Mozilla Firefox installs protocol handlers for Mozilla-specific protocols, such as the FirefoxURL and FirefoxHTML protocols. If Microsoft Windows encounters a URL protocol it cannot handle natively it searches the Windows registry for the appropriate protocol handler. When the correct protocol handler is found, Windows passes it the URL string. By design Windows passes the URL string to the protocol handler as it was received without performing any sanitization.
Disabling the Mozilla Firefox protocol handlers will mitigate this vulnerability. To unregister the protocol handlers, delete or rename the following registry keys:
