cisco-sa-sbrv-cmdinjection-Z5cWFdK: Cisco Small Business RV Series Routers Command Injection Vulnerability

First published: Wed Nov 03 2021(Updated: )

A vulnerability in the web-based management interface of certain Cisco Small Business RV Series Routers could allow an authenticated, remote attacker with administrative privileges to inject arbitrary commands into the underlying operating system and execute them using root-level privileges. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending malicious input to a specific field in the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux operating system as a user with root-level privileges. There are no workarounds that address this vulnerability.
