TID 7001907 gives details about a potential security vulnerability with Apache, or more specifically ApacheAdmin, on NetWare 6.5 after you've installed an OES2 Linux server into the same tree.
However there seems to (currently) be some ambiguity about the actual cause and suggested fix.
Here's one way of securing access to port 2200 on your NetWare server using FILTCFG.
PROTOCOL-SERVICE IP, NWWebMgr, pid=TCP port=2200 srcport=<All>, NetWare Web Manager
Packet Type: NWWebMgr
Packet Type: NWWebMgr
Src Addr Type: Network
Src IP Address: network/netmask
