ABB Cylon Aspect 3.08.01 (calendarFileDelete.php) Arbitrary File Deletion

The BMS/BAS controller suffers from an arbitrary file deletion vulnerability. Input passed to the ‘file’ parameter in calendarFileDelete.php is not properly sanitised before being used to delete calendar files. This can be exploited by an unauthenticated attacker to delete files with the permissions of the web server using directory traversal sequences passed within the affected POST parameter.
