CVE-2022-20825

Severity High
Score 9.8/10

Summary

A vulnerability in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an unauthenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to insufficient user input validation of incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on an affected device using root-level privileges. Cisco has not released software updates that address this vulnerability.
