Description
A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to bypass authorization and modify the configuration of an affected system. The vulnerability is due to insufficient authorization checking on an affected system. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based management interface of an affected system.

This could allow the attacker to modify the configuration of an affected system.
