Shodan matched these CVEs against the service banners it saw on 91.202.208.139 (dylanit.nl), which advertise exim 4.99.4, lua-nginx-module 1.31.1.1, openresty 1.31.1.1, openssh 8.0. 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-2026-66141 CVE-2026-66140 CVE-2026-60002 CVE-2026-60001 CVE-2026-60000 CVE-2026-59999 CVE-2026-59998 CVE-2026-59997 CVE-2026-59996 CVE-2026-59995 CVE-2026-35414 CVE-2026-35388 CVE-2026-35387 CVE-2026-35385 CVE-2025-32728 ...and 13 more
What to do
Confirm the running versions on 91.202.208.139 and compare them against the current security release for each package before treating any single CVE as live.

91.202.208.139 (dylanit.nl) reports exim 4.99.4, lua-nginx-module 1.31.1.1, openresty 1.31.1.1, openssh 8.0. 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: 91.202.208.139
FTP transmits credentials in cleartext.
What to do
Restrict 21/tcp to a VPN, bastion, or allow-listed source range.
asset: 91.202.208.139:21
Public SSH invites credential stuffing and key brute force.
What to do
Restrict 22/tcp to a VPN, bastion, or allow-listed source range.
asset: 91.202.208.139:22
Commonly a leftover listener or an implant default port.
What to do
Restrict 4444/tcp to a VPN, bastion, or allow-listed source range.
asset: 91.202.208.139:4444
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://dylanit.nl/
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://dylanit.nl/
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://dylanit.nl/
Without clientTransferProhibited, a compromised registrar account can move the domain to another registrar in days, with no second step.
What to do
Enable the transfer lock (and registrar lock, if offered) in the registrar control panel.
asset: dylanit.nl
Check it is not an open relay.
What to do
Restrict 25/tcp to a VPN, bastion, or allow-listed source range.
asset: 91.202.208.139:25
Lets browsers guess content types, which turns some upload and text endpoints into script injection points.
What to do
Send `X-Content-Type-Options: nosniff` on every response.
asset: https://dylanit.nl/
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://dylanit.nl/
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: dylanit.nl
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: dylanit.nl
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"`.
