Official description

FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to 1.5.10.1812, the listing tables on multiple management pages (Host, Storage, Group, Image, Printer, Snapin) are vulnerable to Stored Cross-Site Scripting (XSS), due to insufficient server-side parameter sanitization in record creations/updates and a lack of HTML escaping in listing tables. Version 1.5.10.1812 patches the issue.
