Novell eDirectory Host Environment Service (dhost.exe) HTTP Connection Header DoS

This script is Copyright (C) 2008-2011 Tenable Network Security, Inc.


Synopsis :

The remote directory service is affected by a denial of service issue.

Description :

The remote host is running eDirectory, a directory service software
from Novell.

The installed version of eDirectory is affected by a denial of service
issue. By sending an HTTP request with a specially crafted
'Connection' header to the server, an unauthenticated attacker may be
able to trigger a denial of service condition causing dhost.exe to
consume 100% of the CPU and crash the system.
