ZoomEye can show internet-visible services and product fingerprints associated with Proxmox VE and VMware, but its result counts are not counts of vulnerable hypervisors. They do not, on their own, establish that a management interface is directly reachable, identify who owns an asset, confirm its software version, or show that it has been compromised.
What ZoomEye can—and cannot—show
ZoomEye’s API documentation says its search covers IPv4 and IPv6 devices and websites, with matches across data from protocols such as HTTP, SSH, and FTP. Depending on the query, searchable information can include ports, services, product and version fingerprints, titles, banners, and update time. Its documentation also describes global keyword matching across data such as HTTP/HTTPS headers and bodies, SSL information, page titles, and other protocol banners.

That breadth makes query scope important. A port query, a product fingerprint query, and a broad title search do not measure the same thing. A match is an observation in ZoomEye’s data; it is not proof that a privileged management UI is reachable from the public internet. Nor does it establish a vulnerable version, unique physical or virtual host, asset owner, or compromise.
What the published result counts say
The figures below were reported by two DEV Community authors describing ZoomEye queries in September 2026. They are attributed search results, not independently verified measurements of distinct, publicly reachable management interfaces or vulnerable systems.
| Reported query | Reported results | What the report establishes |
|---|---|---|
port:8006 |
3,988 | kozhevniko reported this count for a September 2026 collection. The author identifies port 8006 with the Proxmox VE web management interface, but says the count does not establish each host’s version, owner, or direct public reachability. DEV Community post, September 17, 2026 |
title:"Proxmox" |
522,829 | The same author warns this broad title-match count is not a count of exposed hypervisors; it includes matches such as documentation, tutorials, forums, and marketing pages. DEV Community post, September 17, 2026 |
app="VMware ESXi" |
414,092 | yutianle reported this fingerprint count for a query said to have run on September 20, 2026. It is not independently verified as a count of reachable ESXi management interfaces or vulnerable hosts. DEV Community post, September 24, 2026 |
app="Proxmox VE" |
140,746 | yutianle reported this fingerprint count for a query said to have run on September 20, 2026. The report does not establish unique, attributable, publicly reachable management interfaces. DEV Community post, September 24, 2026 |
app="vSphere" |
12,354 | yutianle reported this fingerprint count for a query said to have run on September 20, 2026; it is not a verified count of exposed or vulnerable systems. DEV Community post, September 24, 2026 |
The figures answer what those authors reported seeing for particular queries and collection times—not how many Proxmox or VMware systems are vulnerable. No population-level count of vulnerable hypervisors is established by these reports. Counts can change as observations and query results change, and query syntax determines what gets counted.

How to interpret a match before treating it as exposure
- Port match: A service observed on a port is a clue, not confirmation that an administrator can reach its interface from an arbitrary public network.
- Product fingerprint: An application label may suggest a product, but it does not by itself verify the installed version or vulnerability status.
- Title or keyword match: A text match can describe a page about a product rather than a product’s management endpoint.
- Result count: A count is not necessarily a count of unique assets, and the cited reports do not independently validate ownership or compromise.
To compare results meaningfully, note the exact query and whether it is scoped to a port/service or based on a broad title or product match. Also record the collection date and check whether version, direct reachability, uniqueness, and asset ownership were actually established. Where the reports do not provide those checks, those facts remain unknown.
How organizations should validate findings
For defensive asset management, use internet-wide search as a lead and compare carefully scoped findings with the organization’s own inventory. Confirm suspected assets and their exposure through authorized channels; then establish reachability, software version, ownership, and configuration before deciding what to fix. Do not treat a search result alone as proof of a vulnerable system.
The September 17, 2026 DEV Community post recommends keeping Proxmox port 8006 off the public internet and adding a second factor where the interface cannot be moved. Those are recommendations from the post’s author, not vendor instructions cited here. The broader principle is to avoid exposing privileged management surfaces unnecessarily and to verify the actual network path rather than infer it from a fingerprint.

ESXi hardening: restrict management access, not packet forwarding
Broadcom’s guidance for ESXi 7.0, 8.0, and later recommends using Strict Lockdown Mode to restrict direct access to the management interface, limiting firewall rules to essential services, and segregating management, vMotion, and data traffic. These are configuration and network controls; a ZoomEye result alone cannot tell an administrator whether they are in place.
Broadcom specifically cautions: “Disabling packet forwarding is not a standard security best practice for ESXi.” Its Knowledge Base article also says ESXi “does not possess a supported parameter to toggle ‘packet forwarding’ as a hardening measure.” Administrators should follow supported ESXi hardening guidance rather than attempt packet-forwarding changes as a substitute for access restrictions.
