CVE-2021-1419
Cisco Access Points SSH Management Privilege Escalation Vulnerability
Overview
Description
A vulnerability in the SSH management feature of multiple Cisco Access Points (APs) platforms could allow a local, authenticated user to modify files on the affected device and possibly gain escalated privileges. The vulnerability is due to improper checking on file operations within the SSH management interface. A network administrator user could exploit this vulnerability by accessing an affected device through SSH management to make a configuration change. A successful exploit could allow the attacker to gain privileges equivalent to the root user.
