Description: A vulnerability was reported in phpMyAgenda. A remote user can include and execute arbitrary code on the target system.
The 'agenda.php3' script does not properly validate user-supplied input in the 'rootagenda' parameter. If register_globals is enabled,
a remote user can supply a specially crafted URL to cause the target system to include and execute arbitrary PHP code from a remote
location. The PHP code, including operating system commands, will run with the privileges of the target web service.
