Authenticated router reboot via malformed HTTP request
Published Oct 2, 2024 · Updated Oct 2, 2024
Input validation failure in Cisco RV042, RV042G, RV320, and RV325 web interfaces allows remote authenticated users to reboot routers. The interface processes a crafted HTTP request without properly validating packet input, forcing an unexpected device reload. Valid Administrator credentials and management-interface access are required; exploitation interrupts routing until the device restarts.
