Shodan matched these CVEs against the service banners it saw on 212.117.184.180 (apolut.net), which advertise nginx 1.18.0. 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-2025-23419 CVE-2023-44487 CVE-2021-23017 CVE-2021-3618
What to do
Confirm the running versions on 212.117.184.180 and compare them against the current security release for each package before treating any single CVE as live.

212.117.184.180 (apolut.net) reports nginx 1.18.0. 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: 212.117.184.180
Without HSTS the browser will still try http:// first on a fresh visit, which is the window an on-path attacker uses.
What to do
Send `Strict-Transport-Security: max-age=31536000; includeSubDomains` once you are sure everything works over HTTPS.
asset: https://apolut.net/
CSP is the main defence that limits what an injected script can do. Without it, any XSS bug is fully exploitable.
What to do
Start with a report-only policy, tighten it against the reports, then enforce.
asset: https://apolut.net/
No X-Frame-Options or CSP frame-ancestors directive, so another site can load this page invisibly inside its own and trick users into clicking.
What to do
Send `X-Frame-Options: DENY` or `Content-Security-Policy: frame-ancestors ’none’`.
asset: https://apolut.net/
Full URLs — including any tokens or IDs in them — are sent to every third party the page links to.
What to do
Send `Referrer-Policy: strict-origin-when-cross-origin`.
asset: https://apolut.net/
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: apolut.net
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"`.
