## GitHub Issue: Phase 3 PR C — Router Firmware Elevated to First-Class CVE Target in Simulation
A major simulation project is advancing a core component of its cyber defense model, formally elevating router firmware to a primary attack surface. The update, designated as Phase 3's "PR C," redefines routers as first-class CVE targets, integrating their firmware directly into the procedural vulnerability lifecycle that drives the simulation's timeline. This shift means each simulated router will now be generated with a vendor-stamped firmware version, and firmware-specific CVEs will be published over simulated "game time" using the same system that governs service vulnerabilities. The change significantly expands the attack vectors available to simulated penetration testing tools.

The implementation introduces new code modules to manage this firmware ecosystem. A dedicated pool file defines version templates for six major router vendors: Cisco IOS, MikroTik RouterOS, DD-WRT, OpenWRT, pfSense, and EdgeOS. These templates are designed to be compatible with the existing timeline "walker" system. Furthermore, a new firmware lookup module mirrors the structure of the project's existing vulnerability system, providing functions to find firmware CVEs for a given vendor and version at a specific point in time, and to identify the latest safe firmware patch available. This structural parity allows exploitation tools like `msfconsole` to target routers through either a traditional port-service vulnerability or a newly modeled firmware flaw.

This architectural pivot carries notable implications for the simulation's realism and complexity. By treating firmware with the same procedural rigor as software services, the model more accurately reflects real-world security dynamics where outdated or vulnerable router firmware is a critical enterprise risk. The ability for simulated system administrators to run `apt upgrade` on a router to patch both services and firmware in a single operation adds a layer of defensive gameplay. Notably, this firmware-focused PR was originally slated as "PR D" but was promoted in priority after another planned feature, local firewalls, was deferred to a later phase, indicating its strategic importance to the project's evolving "defense treadmill."
