CVE-2002-2228: MailScanner before 4.0 5-1 and before 3.2 6-1 allows remote attackers to bypass protection via attachments...

Security readout for executives and security teams

This CVE describes an old MailScanner attachment-filtering weakness. A remote sender could bypass protection by using attachment filenames with leading spaces, trailing spaces, or character encodings MailScanner could not process. The provided sources do not include CVSS, active exploitation evidence, or detailed vendor remediation guidance. Exposure is most likely on legacy mail gateways or servers still running affected MailScanner versions. Organizations that never used MailScanner, or that upgraded beyond the affected release lines, are unlikely to be exposed based on the supplied sources. Treat this as a legacy exposure check, not an emergency based on the supplied evidence. Prioritize it if MailScanner remains in production mail flow, because bypassed attachment filtering can weaken malware and policy controls. Mitigation focus: Inventory mail gateways and identify any MailScanner deployments.; Verify MailScanner versions against the affected version boundaries in the CVE record.; Upgrade affected MailScanner installations or follow current vendor guidance..
