Multiple buffer overflows in the ESMTP service of Lotus Domino 5.0.2c and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via long (1) "RCPT TO," (2) "SAML FROM," or (3) "SOML FROM" commands.

Security readout for executives and security teams

A very old flaw in the email service (ESMTP) of Lotus Domino 5.0.2c and earlier lets a remote attacker crash the mail server and possibly run their own code by sending overly long commands. Any organization still running this decades-old, unsupported mail platform faces meaningful risk to email availability and server integrity. Exposure is limited to legacy Lotus Domino 5.0.2c or earlier servers with the ESMTP service reachable from untrusted networks. Such deployments are rare in 2026, but any surviving instance in production or lab environments would be directly at risk. Low urgency for most modern enterprises because Lotus Domino 5.x has been out of support for many years. However, if legacy Domino is still in use anywhere in the estate, treat as high priority: plan immediate isolation and a funded migration to a supported mail platform. Mitigation focus: Inventory any Lotus/IBM/HCL Domino instances and confirm none run version 5.0.2c or earlier.; Retire or upgrade legacy Domino servers to a currently supported release per vendor guidance.; Restrict inbound SMTP to a hardened, supported mail gateway rather than exposing legacy Domino directly..
