Unauthenticated code execution via insufficient upload checks
Published Feb 10, 2022 · Updated Nov 6, 2024
Stack-based buffer overflow in the upload module of Cisco RV340 and RV345 Series Routers allows remote attackers to execute non-root code. The module applies insufficient boundary checks while processing specific malicious HTTP requests, allowing data to exceed a stack buffer boundary. No authentication or user interaction is required, and successful exploitation runs code with non-root privileges on the device.

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.
