admin/index.php in PHP iCalendar 2.3.4, 2.24, and earlier does not require administrative authentication for an addupdate action, which allows remote attackers to upload a calendar (aka .ics) file with arbitrary content to the calendars/ directory outside the web root.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
