Because of a incorrect escaped exec command in MagpieRSS in 0.72 in the /extlib/Snoopy.class.inc file, it is possible to add a extra command to the curl binary. This creates an issue on the /scripts/magpiedebug.php and /scripts/magpiesimple.php page that if you send a specific https url in the RSS URL field, you are able to execute arbitrary commands.
