Shodan matched these CVEs against the service banners it saw on 84.198.252.38 (cairox.be), which advertise http server 2.4.41. These are version-fingerprint matches, not confirmed exploits: a distribution may have back-ported the fix while leaving the banner unchanged. Severity reflects the volume of known issues associated with this host, not a CVSS score. CVE-2026-49975 CVE-2026-44631 CVE-2026-44186 CVE-2026-44185 CVE-2026-44119 CVE-2026-43951 CVE-2026-42536 CVE-2026-42535 CVE-2026-34356 CVE-2026-34355 CVE-2026-34059 CVE-2026-34032 CVE-2026-33857 CVE-2026-33523 CVE-2026-33007 ...and 84 more
What to do
Confirm the running versions on 84.198.252.38 and compare them against the current security release for each package before treating any single CVE as live.

asset: 84.198.252.38
84.198.252.38 (cairox.be) reports http server 2.4.41. Publishing precise versions lets anyone match the host against a CVE feed without probing it, which is how targets get shortlisted for mass exploitation after a new advisory lands.
What to do
Suppress version tokens in server banners (for example `ServerTokens Prod` in Apache) and keep the packages current.
asset: 84.198.252.38
Receivers are asked to report spoofing but not to block it. This is the right first step, and the wrong place to stop.
What to do
Once reports look clean, move to p=quarantine, then p=reject.
asset: cairox.be
Answers for this domain are not signed, so a resolver cannot tell a forged response from a real one.
What to do
Enable DNSSEC at your DNS host and publish the DS record at the registrar.
asset: cairox.be
Mail to this domain can be downgraded to plaintext by an on-path attacker, because senders have no way to know TLS is required.
What to do
Publish an MTA-STS policy (a TXT record plus a small HTTPS-hosted file).
asset: cairox.be
Any public certificate authority may issue certificates for this domain. CAA lets you name the ones allowed to.
What to do
Add a CAA record naming your CA, e.g. `0 issue "letsencrypt.org"`.
