CVE-2021-1436
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to conduct path traversal attacks and obtain read access to sensitive files on an affected system.
Does this matter?
Lower severity and a low EPSS score (0.31%). Track it; it rarely justifies an emergency change on its own.
Description

This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to an affected system. A successful exploit could allow the attacker to view arbitrary files on the affected system.
