CVE-2012-3973

Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 15.0

Description The issue is related to the debugger in the developer-tools subsystem. When remote debugging is disabled, it does not properly restrict access to the remote-debugging service. This allows remote attackers to execute arbitrary code by leveraging the presence of the HTTPMonitor extension and connecting to that service through the HTTPMonitor port.

Recommendations For versions prior to 15.0, update to version 15.0 or later to resolve the issue. As a temporary workaround, consider disabling the HTTPMonitor extension until a patch is available. Restrict access to the remote-debugging service to minimize the risk of exploitation.
