Security readout for executives and security teams
This is an old Sendmail relay-control bypass. A remote attacker could make a vulnerable mail server treat a blank spoofed DNS hostname in a way that bypasses check_relay restrictions, potentially allowing unauthorized email relaying. Exposure is most likely on legacy internet-facing Sendmail servers running versions 8.9.0 through 8.12.6, especially systems that still accept SMTP traffic directly from untrusted networks. Treat as a legacy exposure issue. Prioritize quickly if affected Sendmail is internet-facing or business email reputation matters, but do not assume active exploitation from the provided evidence. Mitigation focus: Inventory Sendmail versions and identify any 8.9.0 through 8.12.6 deployments.; Check Sendmail 8.12.7 and vendor advisories for fixed or supported upgrade guidance.; Restrict SMTP exposure to required networks while remediation is planned..
