Vendor URL    :  http://www.pcdoc24.de (vendor website seem down)
Vulnerability :  Remote Command Execution
Risk          :  High


==================================================================
An attacker may exploit this vulnerability to execute commands on
the remote host by adding special parameters to wps_shop.cgi script.

There is no filtering special character when open file in sub showartikel.
Vulnerable code :

###########
sub showartikel {
###########
        cartfooter();
        open(DATA, "$shopcatsdir/$info{'cat'}/$info{'art'}"); 
        lock(DATA); 
.......................................
.......................................

}

Fix :

add :
$info{'art'} =~ s/[;<>\*\|'&\$!?#\(\)\[\]\{\}:'"\\]//go;

before :
open(DATA, "$shopcatsdir/$info{'cat'}/$info{'art'}"); 
}
