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.

Added to KEV: 23 Aug 2024Federal remediation due: 13 Sept 2024

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.
