Usually, no.
But generally, 3 ways come to mind:
  • If the HTTP server is configured wrong and doesn't recognize the scripts as executables, and serves the content instead
  • If another application on the same server is vulnerable to relative path errors, eg instead of calling /xyz/abc.html the attacker can call /xyz/../../cgi-bin/script.pl
  • If you've got a script that uses templates with variables passed through POST. Those could be set also via GET and potentially serve content you wanted hidden

NAME
CGI::XML - Perl extension for converting CGI.pm variables to/from XML SYNOPSIS
use CGI::XML; $q = new CGI::XML; # convert CGI.pm variables to XML $xml = $q->toXML; $xml = $q->toXML($root); # convert XML to CGI.pm variables $q->toCGI($xml); DESCRIPTION
The CGI::XML module converts CGI.pm variables to XML and vice versa. CGI::XML is a subclass of CGI.pm, so it reads the CGI variables just as CGI.pm would. METHODS
$q = new CGI::XML creates a new instance of CGI::XML. You also have access to all of the methods in CGI.pm. $q->toXML([$root]) where $root is an optional parameter that specifies the root element. By default, toXML will not return a root element. $q->toCGI($xml) where $xml is the XML you would like to convert to CGI.pm parameters. Values in the XML will overwrite any existing values if they exist. NOTE
CGI::XML does not currently handle multiple selections passed from HTML forms. This will be added in a future release. AUTHOR
