A PDF viewer installed on the remote host is affected by a command execution vulnerability.
The version of Foxit Reader installed on the remote Windows host is prior to 3.2.1. It is, therefore, affected by an arbitrary program execution vulnerability related to certain '/Type /Action /S /Launch' or '/Launch /Action' sequences. An attacker can exploit these, by tricking a user into opening a crafted PDF file, to cause arbitrary programs to be executed without user permission.
Upgrade to Foxit Reader version 3.2.1.0401 or later.
