Description

The BMS/BAS controller suffers from an arbitrary file deletion vulnerability. Input passed to the 'variant' parameter in clearProjectConfigurationAjax.php is not properly sanitised before being used to delete files. This can be exploited by an authenticated attacker to delete files with root permissions using directory traversal sequences passed within the affected POST parameter.
