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.
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
