All of them on a software version from an earlier observation: a service of that kind is open now.
Not counted: 25 from an older observation (openssh 7.2p2; matched 2026-06-08). See them

Vulnerabilities
Only affects certain platforms (4)
These CVEs only apply when the software runs on a particular platform (for example Windows), and this host's platform is not known. They are not counted.
These CVEs were matched on software this host reported in an earlier observation (matched 2026-06-08), not on a port that is open now, and no service of that kind was open at the latest check (2026-05-24). They are not counted above.
Every port that has answered a connection on this address, and when. A port is listed as open above only when a service was identified on it. Times are UTC.
