Clearswift MIMEsweeper 5.0.5, when it has been upgraded from MAILsweeper for SMTP version 4.3 or MAILsweeper Business Suite I or II, allows remote attackers to bypass scanning by including encrypted data in a mail message, which causes the message to be marked as "Clean" instead of "Encrypted".

Security readout for executives and security teams

This old mail-gateway flaw can let encrypted email content pass as clean on specific upgraded Clearswift MIMEsweeper 5.0.5 systems. The business risk is missed malware, data hiding, or policy bypass in legacy email filtering. The public bundle does not show active exploitation or a CVSS score. Exposure is likely limited to organizations still running this legacy Clearswift MIMEsweeper version and upgrade path. Modern replacements or fresh installations are not identified as affected in the provided sources. Prioritize this if legacy Clearswift mail filtering still protects inbound or outbound email. Otherwise, treat it as a targeted legacy-asset verification item rather than an enterprise-wide emergency. Mitigation focus: Identify any Clearswift MIMEsweeper 5.0.5 installations and their upgrade history.; Check Clearswift advisory or update readme for vendor-recommended corrective action.; Replace unsupported legacy mail gateways with supported filtering infrastructure..
