FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Versions 1.5.10.1673 and below contain an authentication bypass vulnerability. It is possible for an attacker to perform an unauthenticated DB dump where they could pull a full SQL DB without credentials. A fix is expected to be released 9/15/2025. To address this vulnerability immediately, upgrade to the latest version of either the dev-branch or working-1.6 branch. This will patch the issue for users concerned about immediate exposure. See the FOG Project documentation for step-by-step upgrade instructions: https://docs.fogproject.org/en/latest/install-fog-server#choosing-a-fog-version.

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 buildRow() method in fogpage.class.php substitutes data values into HTML table cell templates using strreplace() without any HTML escaping. An unauthenticated attacker who knows any registered host's MAC address can POST malicious inventory values (e.g. sysproduct, sysserial) to /service/inventory.php, which stores them in the database. When an administrator opens the Group Inventory tab, the payload renders as executable HTML/JavaScript in the admin's browser. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.

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 clearAES and clearPMTasks methods in FOGPage can be invoked by an unauthenticated attacker via a single HTTP GET request through the public client node endpoint. This allows remote wiping of host AES encryption credentials and deletion of all power management scheduled tasks, with no login, session, or CSRF token required. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.

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 selectForm() helper in fogpage.class.php renders <option> labels using raw, unescaped user input. An unauthenticated attacker who knows any registered host's MAC address can POST a malicious sysproduct value to /service/inventory.php, which is stored in the database. When an administrator opens Reports > Inventory, the payload breaks out of the <option> element and executes arbitrary JavaScript in the admin's browser. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.

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.

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.
