Security readout for executives and security teams
This is an old local bypass issue in Tiny Personal Firewall 1.0 and 2.0. A user already on the machine could send unusual TCP traffic through non-Windows protocol adapters and avoid the firewall’s filtering. The sources do not show remote compromise, active exploitation, CVSS severity, or a named patch. Exposure is likely limited to legacy endpoints still running Tiny Personal Firewall 1.0 or 2.0. Risk depends on whether local users can install or use alternate protocol adapters and whether the firewall is relied on for outbound control. Treat as a legacy exposure check, not an emergency, unless the product is still deployed on sensitive endpoints. Business urgency comes from reliance on obsolete local firewall filtering rather than evidence of current exploitation. Mitigation focus: Inventory endpoints for Tiny Personal Firewall 1.0 or 2.0.; Check vendor or archived advisory guidance for fixed versions or replacements.; Restrict local ability to install or use alternate protocol adapters..
