This option is only available for a user logged with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin. (Tenant level users do not have this privilege). The “Change Favicon” (Favorite Icon) option can be mis-used to upload a malicious file ending with .png extension to masquerade as image file. This is possible only after a user with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin has successfully authenticated and logged in.
