Summary

A vulnerability in the CLI of Cisco SD-WAN vManage Software could allow an authenticated, local attacker to elevate privileges on an affected system. To exploit this vulnerability, an attacker would need to have a valid Administrator account on an affected system. The vulnerability is due to incorrect privilege assignment. An attacker could exploit this vulnerability by logging in to an affected system with an Administrator account and creating a malicious file, which the system would parse at a later time. A successful exploit could allow the attacker to obtain root privileges on the affected system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
