Description:
Some vulnerabilities have been discovered in myEvent, which can be exploited by malicious users to conduct script insertion and SQL injection attacks, and by malicious people to compromise a vulnerable system.

1) Input passed to the "event_desc" parameter in addevent.php is not properly sanitised before being used. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site when a malicious event is viewed.

2) Input passed to the "event_id" parameter in addevent.php and del.php, and to the "event_desc" in addevent.php is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

3) Input passed to the "myevent_path" parameter in event.php and initialize.php is not properly verified before being used to include files. This can be exploited to execute arbitrary PHP code by including PHP files from local or external resources.

4) Input passed to the "myevent_path" parameter is also not properly verified in myevent.php and viewevent.php before being used to include files. This can be exploited to execute arbitrary PHP code by including PHP files from local or external resources.

Successful exploitation requires that "register_globals" is enabled and "magic_quotes_gpc" is disabled.

Solution:
Edit the source code to ensure that input is properly sanitised.
