"The version of ManageEngine Desktop Central installed on the remote
host is affected by an arbitrary file upload vulnerability due to the
'AgentLogUploadServlet' script not properly sanitizing user-supplied
input to the 'filename' parameter. A remote, unauthenticated attacker
can exploit this issue to upload files containing arbitrary code and
then execute them on the remote host with NT-AUTHORITY\SYSTEM
privileges.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
