Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 66

Description The issue is related to the management of resources when the source for resources on a page is through an FTP connection. It is possible to trigger a series of modal alert messages for these resources through invalid credentials or locations, leading to a denial of service attack. These messages cannot be immediately dismissed.

Recommendations For versions prior to 66, update to version 66 or later to resolve the issue. As a temporary workaround, consider avoiding the use of FTP connections for resource sourcing until the update is applied. Restrict access to FTP resources to minimize the risk of exploitation.
