Official Description
Kerio Personal Firewall 4.0 (KPF4) allows local users with administrative privileges to bypass the Application Security feature and execute arbitrary processes by directly writing to \device\physicalmemory to restore the running kernel's SDT ServiceTable.
Technical Analysis
CVE-2004-1658 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
