CVE-2023-20045Network attack vector

Root command execution via management request injection

Published Jan 19, 2023 · Updated Aug 2, 2024

Command injection in Cisco Small Business RV160 and RV260 router firmware before 1.0.01.04 allows remote authenticated users to run commands. Cisco attributes the flaw to insufficient input validation in the web-based management interface but does not disclose the request parameter or command-construction path. Administrator-level credentials are required, and successful exploitation executes arbitrary commands with root privileges over LAN or enabled WAN management.
