This affects an unknown function of the file /ThemeAndWidgets.xhtml of the component Theme Customization. Performing a manipulation of the argument uploadLogo results in unrestricted upload. Remote exploitation of the attack is possible. The exploit is now public and may be used. Upgrading to version 6.10 mitigates this issue. You should upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product."
