"The version of tested product installed on the remote host is prior to
12.3X48-D80. It is, therefore, affected by a vulnerability in the Veriexec
subsystem of Juniper Networks Junos OS allowing an attacker to fully compromise
the host system. A local authenticated user can elevate privileges to gain full
control of the system even if they are specifically denied access to perform
certain actions as referenced in the JSA10956 advisory.
Note that Nessus has not tested for this issue but has instead relied only
 on the application's self-reported version number.");
