FOG: Authenticated low-privileged API user can modify Storage Nodes and reach root command execution

FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to 1.5.10.2253 and 1.6.0-RC-1, an authenticated API-enabled user with uType=1 who possesses both the user's API token and the global FOG API token can use PUT /fog/storagenode/{id}/edit to modify Storage Node user, pass, and ftppath fields because the API validates the credentials but does not enforce an administrator-only role. With storage replication enabled and a usable Storage Node, FOGImageReplicator interpolates those fields into an lftp command executed through proc_open() by the root-running service, allowing the low-privileged user to execute commands as root. This issue is fixed in versions 1.5.10.2253 and 1.6.0-RC-1.

FOG adInfo endpoint is reported to disclose the Active Directory join password

FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to 1.5.10.1870, the management adInfo() endpoint in packages/web/lib/fog/fogpage.class.php was reported to return the FOG_AD_DEFAULT_PASSWORD value in its domainpass JSON field and to be dispatchable through node=ipxe without an authenticated session. The response was also consumed by host and group Active Directory configuration interfaces. This could disclose the default domain-join credential to a remote unauthenticated requester. This vulnerability is fixed in 1.5.10.1870.

FOGProject has stored XSS via unescaped option label in selectForm() accessible from unauthenticated inventory endpoint

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.

FOGProject has stored XSS via unauthenticated inventory service renders unescaped in Host Management page

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.

FOGProject has unauthenticated clearAES and clearPMTasks that allow remote destruction of host encryption keys and power schedules

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.

FOGProject has stored XSS via unescaped inventory data in buildRow() rendered on Group Inventory tab

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 `str_replace()` 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 vulnerable to unauthenticated SSRF via `/fog/service/getversion.php`

FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Versions 1.5.10.1754 and below contain an unauthenticated SSRF vulnerability in getversion.php which can be triggered by providing a user-controlled url parameter. It can be used to fetch both internal websites and files on the machine running FOG. This appears to be reachable without an authenticated web session when the request includes newService=1. The issue does not have a fixed release version at the time of publication.

FOG has Stored XSS in Multiple Management Pages

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.

FOG has a command injection in /fog/management/export.php?filename=

FOG is a cloning/imaging/rescue suite/inventory management system. Prior to 1.5.10.34, packages/web/lib/fog/reportmaker.class.php in FOG was affected by a command injection via the filename parameter to /fog/management/export.php. This vulnerability is fixed in 1.5.10.34.

FOG's authentication bypass leads to full SQL DB dump

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.

configureNFS in lib/common/functions.sh in FOG through 1.5.10 allows local users to gain privileges by mounting a crafted NFS share (because of no_root_squash and insecure). In order to exploit the vulnerability, someone needs to mount an NFS share in order to add an executable file as root. In addition, the SUID bit must be added to this file.

Multiple cross-site scripting (XSS) vulnerabilities in FOG 0.27 through 0.32 allow remote authenticated users to inject arbitrary web script or HTML via the (1) Printer Model field to the Printer Management page, (2) Image Name field to the Image Management page, (3) Storage Group Name field to the Storage Management page, (4) Username field to the User Cleanup FOG Configuration page, or (5) Directory Path field to the Directory Cleaner FOG Configuration page.

NFS server misconfiguration allows file access outside the exported directory

FOG is a free open-source cloning/imaging/rescue suite/inventory management system. There is a security issue with the NFS configuration in /etc/exports generated by the installer that allows an attacker to modify files outside the export in the default installation. The exports have the no_subtree_check option. The no_subtree_check option means that if a client performs a file operation, the server will only check if the requested file is on the correct filesystem, not if it is in the correct directory. This enables modifying files in /images, accessing other files on the same filesystem, and accessing files on other filesystems. This vulnerability is fixed in 1.5.10.30.

FOG path traversal via unauthenticated endpoint

FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to version 1.5.10, an endpoint intended to offer limited enumeration abilities to authenticated users was accessible to unauthenticated users. This enabled unauthenticated users to discover files and their respective paths that were visible to the Apache user group. Version 1.5.10 contains a patch for this issue.

FOG SSRF via unauthenticated endpoint(s)

FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to version 1.5.10, a server-side-request-forgery (SSRF) vulnerability allowed an unauthenticated user to trigger a GET request as the server to an arbitrary endpoint and URL scheme. This also allows remote access to files visible to the Apache user group. Other impacts vary based on server configuration. Version 1.5.10 contains a patch.

FOG stored XSS on log screen via unsanitized request logging

FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to version 1.5.10.15, due to a lack of request sanitization in the logs, a malicious request containing XSS would be stored in a log file. When an administrator of the FOG server logged in and viewed the logs, they would be parsed as HTML and displayed accordingly. Version 1.5.10.15 contains a patch. As a workaround, view logs from an external text editor rather than the dashboard.

FOGProject v1.5.9 is affected by a File Upload RCE (Authenticated).

FOG leaks sensitive information (AD domain, username and password)

FOG is a cloning/imaging/rescue suite/inventory management system. FOG Server 1.5.10.41.2 can leak AD username and password when registering a computer. This vulnerability is fixed in 1.5.10.41.3 and 1.6.0-beta.1395.

FOG has a Log Information Disclosure

FOG is a cloning/imaging/rescue suite/inventory management system. FOG Server 1.5.10.41.4 and earlier can leak authorized and rejected logins via logs stored directly on the root of the web server. FOG Server creates 2 logs on the root of the web server (fog_login_accepted.log and fog_login_failed.log), exposing the name of the user account used to manage FOG, the IP address of the computer used to login and the User-Agent. This vulnerability is fixed in 1.5.10.47.

FOG Authenticated File Upload RCE

FOG is a cloning/imaging/rescue suite/inventory management system. An improperly restricted file upload feature allows authenticated users to execute arbitrary code on the fogproject server. The Rebranding feature has a check on the client banner image requiring it to be 650 pixels wide and 120 pixels high. Apart from that, there are no checks on things like file extensions. This can be abused by appending a PHP webshell to the end of the image and changing the extension to anything the PHP web server will parse. This vulnerability is fixed in 1.5.10.41.
