RE: Bug in MAS90 Accounting Platform remote access?

[<mbwhite () swbell net>]

What OS and version of the MAS 200 host program was tested?  The same
process against ver 3.6 under NT4 provided the message "The Host cannot run
the specified program".

A single CTRL+q however, seems to disable the host.  Sending a CTRL+o will
return extended host information. IE, installation path, server memory,
listening IP addresses, computer name and process owner.

As a side note I was able to kill the host process entirely by pressing any
of the arrow keys while connected via telnet.  Any currently connected
clients will continue to function but no new connections can be made.

I'll test various versions and post results later this week.

-Mike

Greetings,

Not sure if any previous issues with this application have surfaced
here, but I've run

Sage Software's MAS 200 is an accounting platform which can be
configured to permit remote access to server-side data over TCP/IP. A
host application listens for connections on the server, and all remote
clients use a workstation app to interface with the host.

Running a port scanner determined that the MAS 200 host application
listens for connections on port 10000.....

telnet x.x.x.x  port: 10000

Connected...

<enter>

"The host does not support this application"

<control + x> X 10    <enter>

"The host has been disabled"...

exit

telnet x.x.x.x port: 10000

Connected...

<enter>

"The host has been disabled"...

--------------------------------------------------------------

Checking the status of the host app at the server console revealed it
had indeed been switched to 'Disabled' status, and all access to the
server from clients on the LAN and WAN sides thru the client application
had been suspended. Am i missing something here? Or is it way too easy
DOS this software?
