The remote host is vulnerable to a local flaw in the way that it creates temporary files.
The remote host is running NTOP, a tool for viewing network configuration, usage, statistics, protocols and much more via a web interface. This version of NTOP is reported ot be prone to a local exploit. Specifically, a local attacker can overwrite critical ntop temporary files, leading to an escalation of privileges.
Upgrade to version 3.2 or higher.
