Two tester findings.
1. Windows Server 2016 wrongly flagged as EOL (HIGH) though it still
gets monthly CUs until 2027-01. Cause: is_eoas (active-support
ended 2022) was treated the same as is_eol → MEDIUM/critical-ish
finding even while security patches still flow.
New three-tier model in _build_eol_status():
- is_eol : security support ENDED (eolFrom past, no ESU) →
HIGH, cvss 9.0, title "EOL".
- is_eol_soon : eolFrom within EOL_SOON_DAYS (90) but future →
MEDIUM, cvss 5.5, title "EOL SOON (Nd)".
- is_eoas only: mainstream support ended, security patches still
flow → LOW, cvss 3.0, title "end-of-active-support".
Server 2016 (eoas 2022, eol 2027-01) now → LOW today, flips to
MEDIUM "EOL SOON" ~90d before Jan 2027, HIGH after.
_days_until() handles eolFrom given as a bool (endoflife quirk).
Both check_eol + check_os_eol share _build_eol_status now.
2. Nessus "Scan + Import" failed with "Server disconnected without
sending a response" on launch. That's the Nessus Essentials (free)
API-launch limitation — it drops the connection and the scan never
enters 'running'. The job now catches the launch NessusAPIError: if
the scan already has completed/imported results it imports those
(flagged via job.launch_warning + a clear stage message); otherwise
it fails with an actionable hint ("this edition may not allow
API-triggered scans — launch in the Nessus UI then Sync now").
eol-check loops (router + scheduler) updated to also surface
is_eol_soon findings.
