What the flaw is

The Versa Director GUI contains an unrestricted upload of file with dangerous type vulnerability that allows administrators with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin privileges to customize the user interface. The “Change Favicon” (Favorite Icon) enables the upload of a .png file, which can be exploited to upload a malicious file with a .png extension disguised as an image.

CISA's description

The Versa Director GUI provides an option to customize the look and feel of the user interface. This option is only available for a user logged with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin. (Tenant level users do not have this privilege). The “Change Favicon” (Favorite Icon) option can be mis-used to upload a malicious file ending with .png extension to masquerade as image file. This is possible only after a user with Provider-Data-Center-Admin or Provider-Data-Center-System-Admin has successfully authenticated and logged in.
