An administrator could upload a file containing executable code to the server as a logo file if they rename the file to a supported image file format. The issue is not exploitable by itself unless the administrator account that has access to configuration is hacked. However, site audits may flag this issue, and it can cause security audits (such as PCI) to fail.
