The remote host is vulnerable to a local 'privilege escalation' flaw.
The remote host is running the Alt-N MDaemon mail server. This is a mail server for the Microsoft Windows platform. This version of MDaemon is vulnerable to a flaw where local attackers can overwrite critical MDaemon library files. Successful exploitation would give the local user the ability to escalate privileges to those of the MDaemon server. This would impact confidentiality, integrity, and availability.
Upgrade to version 9.0.7 or 9.54 or higher.
