AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N
Injection endpoint is described as unauthenticated (PR:N); admin must view the page (UI:R); payload executes in the browser rather than the server, so scope changes (S:C) with high C/I and no availability impact.

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.

AnalysisAI
Stored cross-site scripting in FOG Project (open-source imaging/inventory suite) before 1.5.10.1832 and 1.6.0-beta.2313 lets remote attackers persist malicious script via the unauthenticated /service/inventory.php endpoint, which is rendered unencoded on the Host Management Inventory page and executes in any administrator's browser. Because the injection point requires no authentication and the payload runs in a privileged admin session, an attacker can hijack administrator actions and effectively take over host management. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the FOG server's inventory intake endpoint /service/inventory.php, which per the description accepts client-supplied inventory values without authentication; the attacker submits a script payload into a static inventory field that is persisted server-side. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N, 7.3) indicates network-reachable, low-complexity exploitation with high confidentiality and integrity impact but no availability impact, gated by user interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker on a network segment that can reach the FOG server sends a crafted POST to the unauthenticated /service/inventory.php endpoint, embedding a JavaScript payload in a static inventory field such as system model or serial number. The value is stored verbatim; when a FOG administrator later opens the Host Management Inventory page, the script executes in their authenticated session, letting the attacker steal the admin session or perform administrative actions on their behalf. … |
| Remediation | Vendor-released patch: upgrade to FOG 1.5.10.1832 on the stable branch, or 1.6.0-beta.2313 if running the 1.6 beta line, per advisory GHSA-2r7m-6mqf-5cc4 (https://github.com/FOGProject/fogproject/security/advisories/GHSA-2r7m-6mqf-5cc4). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: identify all FOG Project instances in production and examine /service/inventory.php access logs for suspicious payloads or anomalous activity; implement immediate network-level restrictions on /service/inventory.php access, limiting it to verified administrators and preferably requiring VPN authentication. …
