Pfsense

Pfense is a widely embedded open-source firewall and routing platform deployed across small-business networks, enterprise security architectures, and service-provider infrastructure, where its compact product footprint belies substantial reach across distributed defensive perimeters. Vulnerabilities affecting the vendor skew toward serious outcomes, with an elevated share reaching critical severity and a consistent tendency to acquire public exploit code; the exposure spans the core firewall application and its ecosystem of security packages including Suricata, Snort integration, and DNS filtering modules. The recurring weakness classes—cross-site scripting, path traversal, OS command injection, and dynamic object-attribute manipulation—reflect the complexity of web-based administrative interfaces, shell-command delegation in packet-filtering rules, and plugin architecture, creating a durable attack surface characteristic of appliance-oriented software. Defenders should prioritize patch deployment for this vendor's releases and restrict administrative access to the web interface; live severity and exploitation figures are shown alongside this summary.
