  "account": "An estimated 983,992 FortiGate devices were counted in an analysis of CVE-2025-25249, a heap-based buffer overflow vulnerability affecting FortiOS, FortiSwitchManager, and FortiSASE. This figure, measured on 23 September 2026, represents indexed assets matching a specific fingerprint and is subject to change due to continuous updates to ZoomEye's index. The vulnerability allows attackers to execute unauthorized code or commands via specially crafted packets, which typically require the device to be reachable from an untrusted network. The count supports the argument that a large, visible population of potentially vulnerable devices exists, implying a significant attack surface that could be exploited without deliberate effort. However, the count does not provide details on firmware versions, the specific deployment of devices (edge or internal), support status, or evidence of actual exploitation. To better understand the impact and manage the risk, the analysis recommends re-running the fingerprint query periodically to track changes in exposure and applying the fingerprint logic to an organization's own address ranges for a more accurate inventory.",
  "summary": "983,992 Indexed FortiGate Instances: Reading an Edge-Appliance Count Against CVE-2025-25249 Edge appliances are difficult to measure honestly, because exposure and importance are unrelated properties. A firewall with a pre-authentication packet-processing flaw and a firewall that has never been reachable from an untrusted network can appear in the same fingerprint count.
