Description
FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to versions 1.5.10.1832 and 1.6.0-beta.2313, the unauthenticated inventory service endpoint (`/service/inventory.php`) persists client-supplied values without sanitization, and the Host Management Inventory page renders all static inventory fields into HTML without output encoding, allowing stored cross-site scripting that executes in any administrator's browser. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.
