Craig Morrison Mail Transport System Professional (aka MTS Pro) acts as an open relay when configured to relay all mail through an external SMTP server, which allows remote attackers to relay mail by connecting to the MTS Pro server, then sending a MAIL FROM that specifies a domain that is local to the server.

Security readout for executives and security teams

This is an open-relay flaw in Craig Morrison Mail Transport System Professional. In a specific relay configuration, outsiders could use the organization’s mail server to send mail through it. The main business risk is email abuse, spam distribution, domain reputation damage, and potential blocklisting, not proven direct system compromise. Exposure appears limited to MTS Pro deployments using the described external SMTP relay configuration and reachable by untrusted clients. The source bundle does not provide affected versions, CPEs, or default-install details. Treat as a targeted legacy email-infrastructure risk. Prioritize if MTS Pro is still internet-reachable or handles business mail, because abuse can harm deliverability and brand trust. Mitigation focus: Check current vendor or maintainer guidance for MTS Pro relay behavior.; Disable unauthenticated or broadly trusted SMTP relaying where possible.; Restrict SMTP access to trusted networks or authenticated users..
