Shodan matched these CVEs against the service banners it saw on 37.139.15.112 (maandree.se), which advertise openssh 10.3, nginx 1.30.1. 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-2026-60002 CVE-2026-60001 CVE-2026-60000 CVE-2026-59999 CVE-2026-59998 CVE-2026-59997 CVE-2026-59996 CVE-2026-59995 CVE-2023-51767 CVE-2008-3844 CVE-2007-2768
What to do
Confirm the running versions on 37.139.15.112 and compare them against the current security release for each package before treating any single CVE as live.

asset: 37.139.15.112
37.139.15.112 (maandree.se) reports openssh 10.3, nginx 1.30.1. 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: 37.139.15.112
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: 37.139.15.112:22
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://maandree.se/
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://maandree.se/
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://maandree.se/
Check it is not an open relay.
What to do
Restrict 25/tcp to a VPN, bastion, or allow-listed source range.
asset: 37.139.15.112:25
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://maandree.se/
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://maandree.se/
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: maandree.se
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"`.
