eMule Web Server works on this port. Some versions of this P2P client 
are vulnerable to a DecodeBase16 buffer overflow which would allow an 
attacker to execute arbitrary code.

Thanks to Kostya Kortchinsky for his posting to bugtraq.

Known Vulnerable clients:
eMule 0.42a-d
eMule 0.30e
eMulePlus <1k

* Note: This script only checks if port 4711 is open and if 
it reports banner which contains string eMule. *

Solution: disable eMule Web Server or upgrade to a bug-fixed version 
(eMule 0.42e, eMulePlus 1k or later)
