CVE-2012-3973

First published: Wed Aug 29 2012(Updated: )

The debugger in the developer-tools subsystem in Mozilla Firefox before 15.0, when remote debugging is disabled, does not properly restrict access to the remote-debugging service, which allows remote attackers to execute arbitrary code by leveraging the presence of the HTTPMonitor extension and connecting to that service through the HTTPMonitor port.
