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.","provenance":"source","from":"NVD"},"summary":{"text":"Versa Director's GUI customization feature, specifically the \"Change Favicon\" option, fails to restrict file types on upload, allowing a malicious file to be stored with a .png extension to disguise it as an image. An attacker needs network access to the Director interface and must be authenticated as a Provider-Data-Center-Admin or Provider-Data-Center-System-Admin user, since tenant-level users cannot reach this
