|
|
This exploit targets a weakness in the way the ypupdated RPC
|
||
|
|
application uses the command shell when handling a MAP UPDATE
|
||
|
|
request. Extra commands may be launched through this command
|
||
|
|
shell, which runs as root on the remote host, by passing
|
||
|
|
commands in the format '|<command>'.
|
||
|
|
|
||
|
|
Vulnerable systems include Solaris 2.7, 8, 9, and 10, when
|
||
|
|
ypupdated is started with the '-i' command-line option.
