CVE-2024-20416Network attack vector

Authenticated root code execution via upload boundary failure

Published Jul 17, 2024 · Updated Aug 1, 2024

Remote code execution in Cisco RV340 and RV345 firmware 1.0.03.24 and later allows remote authenticated users to execute code as root. The upload module applies insufficient boundary checks while processing attacker-crafted HTTP requests. Administrative access to the web interface is required, and successful exploitation compromises the device with root privileges.
