VAR-200112-0202

Vulnerability from variot - Updated: 2025-04-03 22:25

Tiny Personal Firewall 1.0 and 2.0 allows local users to bypass filtering via non-standard TCP packets created with non-Windows protocol adapters. Many of these applications only block packets created by the standard Windows protocol adapter. Exploitation will result in a violation of security policy. Tiny Personal Firewall, ZoneAlarm and ZoneAlarm Pro are confirmed vulnerable. It is believed that other applications similar in design may also be vulnerable
