Oracle Exploit broken?

[tuxi at notemail.de (tuxi)]

hi,
i'm not sure if the Oracle exploit isn't buggy i tested it on some
systems which should be vuln. but only once i got a shell and i could
only execute one command then bindshell stops.

[*] Starting Bind Handler.
[*] REMOTE> 220 192.168.0.2 (Oracle XML DB/Oracle9i Enterprise Edition
Release 9.2.0.1.0 - Production) ready.
[*] REMOTE> 331 pass required for DBSNMP
[*] REMOTE> 230 DBSNMP logged in
[*] Trying to exploit target Oracle 9.2.0.1 Universal 0x60616d46
[*] Exiting Bind Handler.
