===============/========================================================
Exploit ID:     CAU-EX-2008-0001
Release Date:   2008.04.04
Title:          ypupdated_exec.rb
Description:    Solaris ypupdated Command Execution
Tested:         Solaris x86/sparc 10, sparc 9, 8, 2.7
Attributes:     Remote, NULL Auth, Elevated Privileges, Metasploit
Exploit URL:    http://www.caughq.org/exploits/CAU-EX-2008-0001.txt
Author/Email:   I)ruid <druid (@) caughq.org>
===============/========================================================

Description
===========

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>'.


Credits
=======

Josh D. <mcpheea@cadvision.com> from Avalon Security Research is
credited with originally discovering this vulnerability.

This Metasploit exploit module was modeled after kcope's exploit
released to Milw0rm on 2008.03.20.
