Summary

Description

The BMS/BAS controller suffers from an arbitrary file deletion vulnerability. Input passed to the 'file' parameter in 'databasefiledelete.php' is not properly sanitised before being used to delete 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.
