Mozilla · Firefox · 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.
