CVE-2002-1121: SMTP content filter engines, including (1) GFI MailSecurity for Exchange/SMTP before 7.2, (2) InterScan Vir...

Security readout for executives and security teams

This issue let attackers send email in RFC2046 message fragments so some SMTP security filters did not inspect the complete message. That could allow malware or prohibited content to pass through mail gateways that organizations relied on for detection. Exposure is most likely in legacy mail gateways or archived configurations using the named products and versions. Modern environments are affected only if they still run old SMTP content filtering stacks or equivalent filters that mishandle message/partial MIME content. Prioritize if legacy email security gateways remain in production. The business risk is control failure: malicious email may bypass filters that leadership assumes are enforcing malware and content policy. Mitigation focus: Inventory SMTP content filtering products and versions.; Upgrade named products beyond the affected versions.; Review vendor guidance for equivalent message/partial handling issues..
