Shodan matched these CVEs against the service banners it saw on 202.68.92.78 (sentinel.dts.net.nz), which advertise php 5.1.6, jquery ui 1.7.1, jquery 1.3.2. 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.

What to do
Confirm the running versions on 202.68.92.78 and compare them against the current security release for each package before treating any single CVE as live.

asset: 202.68.92.78
A visitor who types the address without https, or follows an old link, gets the unencrypted site. On public Wi-Fi that page can be read and rewritten in transit.
What to do
Redirect every http:// request to https:// with a 301, then add HSTS.
asset: https://dts.net.nz/
SPF and DKIM alone do not protect the From: address a person sees. Without DMARC, a spoofed message can pass SPF for some other domain and still display yours.
What to do
Publish `_dmarc.dts.net.nz TXT "v=DMARC1; p=none; rua=mailto:dmarc@dts.net.nz"`, review the reports, then move to p=quarantine and p=reject.

FTP transmits credentials in cleartext.
What to do
Restrict 21/tcp to a VPN, bastion, or allow-listed source range.
asset: 202.68.93.38:21

202.68.92.78 (sentinel.dts.net.nz) reports php 5.1.6, jquery ui 1.7.1, jquery 1.3.2. 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: 202.68.92.78
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://dts.net.nz/
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://dts.net.nz/
202.68.93.38 (darryn.dts.net.nz) reports exim 4.99.5. 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: 202.68.93.38
202.20.5.21 (speedtest.dts.net.nz) reports exim 4.99.5. 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: 202.20.5.21
202.68.93.47 (mail.dts.net.nz) reports exim 4.99.5. 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: 202.68.93.47
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://dts.net.nz/
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: dts.net.nz
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: dts.net.nz
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"`.
