Root execution or reload via malformed HTTP input
Published Jan 13, 2021 · Updated Nov 12, 2024
Improper input validation in Cisco RV110W, RV130, RV130W, and RV215W routers allows remote authenticated users to execute root code or reload devices. The web-based management interface inadequately validates crafted HTTP request input, although Cisco has not disclosed the affected parameters or functions. Valid administrator credentials are required, and WAN reachability exists only when remote management is enabled; the LAN interface cannot be disabled.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
