Description

This module exploits a buffer overflow vulnerability in opcode 21 handled by
rpc.cmsd on AIX. By making a request with a long string passed to the first
argument of the "rtable_create" RPC, a stack based buffer overflow occurs. This
leads to arbitrary code execution.

NOTE: Unsuccessful attempts may cause inetd/portmapper to enter a state where
further attempts are not possible.
