QID: 1004 CVSS Base: 7.5 
Category: Backdoors and trojan horses CVSS Temporal: 6.8
CVE ID: -
Vendor Reference: -
Bugtraq ID: -
Service Modified: 06/04/2009
User Modified: -
There are known backdoors that use specific port numbers. At least one of these ports was found open on this host. This may indicate the presence of a backdoor;
however, it's also possible that this port is being used by a legitimate service, such as a Unix or Windows RPC.
If a backdoor is present on your system, then unauthorized users can log in to your system undetected, execute unauthorized commands, and leave the host
vulnerable to other unauthorized users. Malicious users may also use your host to access other hosts and perform a coordinated Denial of Service attack.

Some well-known backdoors are "BackOrifice", "Netbus" and "Netspy". You should be able to find more information on these backdoors on the CERT
Coordination Center's Web site (www.cert.org
Call a security specialist and test the host for backdoors. If a backdoor is found, then the host may need to be re-installed.
