Security readout for executives and security teams
CVE-2003-0930 is an email security gateway policy-bypass issue in Clearswift MAILsweeper before 4.3.15. The product may miss filenames inside BinHex/HQX encoded attachments, so a prohibited attachment name could pass filtering rules. Business impact depends on whether legacy MAILsweeper is still enforcing attachment policy. Exposure is likely limited to organizations still running Clearswift MAILsweeper versions earlier than 4.3.15 for inbound or outbound email attachment policy enforcement. Prioritize this if legacy MAILsweeper still protects business email. The issue can weaken attachment policy enforcement, but available evidence does not indicate active exploitation or broad modern exposure. Mitigation focus: Inventory any Clearswift MAILsweeper deployments and confirm exact version.; Upgrade MAILsweeper to 4.3.15 or later if still supported.; Review Clearswift or successor-vendor guidance for legacy remediation details..
