  CardBoard Greeting Card CGI Allows Remote Users to Execute Arbitrary
Commands
------------------------------------------------------------------------

SUMMARY

A vulnerability in the <http://www.kilohana.com/dev/> CardBoard greeting
card web software has been discovered. The vulnerability allows Remote
users to execute arbitrary commands on the server with the privileges of
the web server (usually 'nobody').

DETAILS

Vulnerable systems:
CardBoard CGI version 2.4

It seems that the CardBoard CGI does not properly filter out user-supplied
input. A remote attacker can place arbitrary shell commands in the
recipient field causing them to be executed when the greeting card is
sent.
