ePerl: bad handling of ISINDEX queries

    (ePerl is an embedded Perl Interpreter for HTTP servers)

* Description:
    Incorrect Handling of ISINDEX queries (command line argument)
when ePerl runs as a nph-cgi/cgi.

* Cause:
    According with the CGI/1.1 specification, the HTTP
server executes CGI's passing the ISINDEX field as a command
line argument. When ePerl runs and gets this argument
(argc > 1), it fails to set MODE_CGI, then tries to
open the argument for parsing/executing.

    This can lead to arbitrary Perl code being executed on
the server.

* Example:
http://foo.com/some/dir/doit.phtml?/home/ftp/incoming/executemycode.phtml
